Summary: with the development of society and the progress of the times, the demands of our people on the quality of everyday life have increased further, so have the frequency of vegetable production in the sheds at this stage, but with the continued growth of vegetable cultivation in the sheds, with the emergence of various related problems, the prevention and control of the disease and pests of the tomato sheds has become a hot topic for academic circles. On this basis, the paper briefly analyses the techniques used to grow large-scale tomatoes and explores, for information purposes, common pest and disease management programmes in the production of large-scale tomatoes. Keywords: lodge tomato; lodge vegetable; pest and pest control to improve the efficiency of control of common conditions in greenhouse gas tomatoes, the scope of application of scientific choice of medicines, strengthening preventive measures, etc. This paper presents prevention measures for the main diseases, such as tomato ashilosis, anthrax, umbilical disease and white lice, and provides the basis for the relevant authorities to develop appropriate preventive and control measures. The importance of vegetable cultivation in large sheds is an important part of our “basket”, and the production of vegetables in our country has become an important part of the quality of life of our people. The development of our cities and towns has led to the appropriation of a large amount of land, the decreasing area of vegetable cultivation and the declining production of commercial vegetables. Therefore, accelerating the development of vegetable production and improving the quality of agricultural products are important factors affecting the incomes of farmers and the living standards of urban people. Local governments and the agricultural and rural sectors need to be fully aware of the importance of good vegetable production and to promote the transformation of facilities into modern agriculture, on the basis of which new technologies, varieties and equipment will be promoted. The agricultural and rural sectors at all levels need to strengthen the development, introduction, screening and development, introduction, demonstration and improvement of new varieties to adapt them to the local natural environment, thereby increasing their resilience to natural disasters, adapting them to the needs of different varieties in various markets and increasing the efficiency of cultivation. In recent years, the incidence of various diseases in the agricultural production of our facilities has increased every year. The low level of application of many farmers in the production of vegetable plants in facilities makes it necessary to strengthen research into the prevalence of common pests and pests and, depending on their occurrence, to develop appropriate countermeasures. The type of shed is the preferred type of tomato-planting technique 2. 1, which is commonly used. It is clear that the variety of varieties is becoming more diverse as a result of the development of greenhouse-planting, and chang lok county is located in the north, and the form of greenhouses can be used as serials. Farmers should make scientific choices about the type of greenhouse before planting. The main types of huts are small greenhouses, single-body greenhouses, congested greenhouses and solar-heating chambers. For example, in the northern part of the country, winter cultivation usually uses winter-heating greenhouses, which allow for the full use of sunlight, moisture and temperature, and require good light and temperature protection and effective resistance to wind. When building a shed, farmers also determine the area to be built in accordance with crop yields, and in the case of high-yielding farmers, ensure that the quality of raw materials for greenhouse construction, such as the thickness of plastic sheeting, meets the demand for production, so as to prevent the deterioration of plastic sheeting as a result of changes in the natural environment during production. 2. 2 it is clear that the selection of tomato varieties for intensive cultivation is directly related to the economic benefits and yields of tomato production, so that the factors involved should be thoroughly analysed before tomato production takes place. For example, in chang lo county, the land is mostly sandy and crops are dominated by wheat. First, a survey of the current tomatoes to understand the type of tomatoes that consumers currently love would greatly help to improve economic efficiency. At present, the most commonly used tomatoes in the market are roman tomatoes, black pearl tomatoes, cow heart tomatoes and cherry tomatoes. Each tomato requires strict regulation of its conditions of growth and farmers themselves to understand it. Second, based on local ecological factors and the type of disease, new varieties with high resistance, such as roman tomatoes, are selected, albeit highly resistant to the disease, but less resistant to the disease requires careful selection by farmers. Finally, because of the high transport requirements for tomato products, some varieties that can be transported over long distances, such as cherries, which are more robust in the processed form, are selected so that they can remain intact in long distances and do not affect the economic benefits of farmers. 2. 3 optimization of field management begins with light and temperature, which are important determinants of tomato growth and development, especially in large-scale greenhouses, which should be centred on temperature regulation. The main regulatory measures include, first, a certain degree of shade during the day within seven days of the completion of the planting, a reduction in the number of ventilations, and keeping temperature within the greenhouses below 25°c. Second, after the tomato flower period, daytime ventilation is enhanced at 28°c and 20°c at night to prevent excessive tomato production due to excessive temperature differentials. Thirdly, if the temperature in the greenhouse is high, an appropriate amount of wind cooling should be carried out, preferably during the daytime, in order to avoid the freezing of tomatoes by night-time air flows. Fourth, tomato growth requires a high demand for air moisture, a high correlation between temperature and humidity, and dynamic monitoring of water in air at high temperatures. Second, fertilizers and water are the nutrients necessary for the growth and development of tomatoes, farmers are required to manage the fattening to adapt to the demand for tomatoes, and during watering, care is taken to properly water the seedlings and, when the fruit matures, to water them adequately. Eventually, potassium and phosphorus were applied throughout the reproductive period in order to increase the resilience of tomatoes to pests and pests, and more organic fertilizers were applied on a few occasions, using soybean, vegetable and poultry animal manures as fertilizers to increase the resilience of tomatoes. The common pests of tomato cultivation and the control programme 3. 1 tomato ashilosis are in the production of tomatoes in facilities, and grey grapes, a common tomato fungal disease, are not yet known. Of these diseases, green fruit has been the most affected, gradually spreading from flower to fruit surfaces, mostly near the handle, and producing a grey, fury fungi layer. The disease was infected at the back of a leaf, in the form of type v, with a grey and white stain on its mark. The bacterial disease of tomatoes is prone to outbreaks in cold, high-humid, ill-lighted greenhouses, and the spread of the disease is exacerbated by temperatures below 20°c, relative humidity above 97%, weak light conditions, especially persistent clouds. During periods of fruit expansion, the lack of timely ventilation can easily lead to the spread of asymptomosis, leading to fruit decay. In order to prevent the outbreak of ketchup grapes in the facility, it is necessary to determine the appropriate time and number of times during which they will be filled, usually in the morning. In the early stages of the disease, the frequency and intensity of water recharge must be increased, and new technologies such as membrane and subdural drip irrigation must be vigorously developed. Regular clean-up of films to enhance air circulation and light in the greenhouses. The disease tree is to be removed in a timely manner and the fruit is to be transported out of the greenhouse, burned or buried in order to control the spread of the disease and prevent its occurrence. Care is taken to ventilate, and at the end of each irrigation, adequate ventilation is required to release high humidity gas as soon as possible. When the disease develops to control indicators, targeted treatment can be carried out with 25 per cent of the bacterium fungus emulsifiable concentrate 1,500 times the fluid, 50 per cent of the corrosive humid powder and 70 per cent of the methyl sulphate filamentable powder 1,000 times the fluid, one time every six to seven days and two to three consecutive times, with some preventive effect. 3. 2 tomatoma is a plant-centred disease that results in an elliptical or irregular light yellow spot in front of the plant, followed by a grey stain. The disease goes down, and when it increases, the back is covered with ash, and the leaves are curled up and turned yellow. The outbreak of the tomato leaf disease is closely related to plant management, ventilation, flooding, humidity, light and fertilization. Over-density, continuous cultivation, infrequent ventilation, flooding, high humidity, less light, excess nitrogen fattening and growing plants can facilitate or exacerbate outbreaks of disease. Before seeding, the seed is impregnated with hot water at 55 °c, 20 μm and then 30 μm with more than 50 μms of filamentable powder 1,000 times more, which can effectively kill the fungus and then wash it with fresh water and then sprouts. Facility tomato production requires a reasonable rotation mechanism, usually over three years. During the production process, the management of temperature and humidity should be strengthened, the frequency of water and irrigation should be reasonably controlled, and the use of membrane and sub-membrane drip irrigation should be vigorously promoted. Water should be distributed in a timely manner, plant shearing should be done, fertilizing should be observed, and potassium phosphorus should be applied to prevent plants from flourishing. When the control target is met, 25 per cent of amisida humid powder should be sprayed with 2,000 times more liquid, 30 per cent of seed-friendly cream 4,000 times more liquid, 50 per cent of kaiser water dispersed powder 1,500 times more liquid, 96 per cent up to 3,000 times the pyrocin or 60 per cent up to 600 times the anticinogen, plus 1,500 times the silica and 2116,600 times the day. The above-mentioned agents are interchangeable and are sprayed once every 7 to 10 days and twice to three times. 3. 3 tomatomic corrosive disease is found in greenhouse tomatoes, the most common of which is tomato corrosion. It first produces a water stained spot on the umbilical, then slowly spreads to the top of the fruit and collapses into it, colours of dark brown or brown, and some can grow to more than one third, with many consequences。it is a physiological disease caused by calcium deficiency. The water supply is uneven, with prolonged drought, a marked increase in the evaporation of plants, and a shortage of water on the surface of the plants, which leads to umbilical diseases. Excessive nitrogen fertilization, especially ammonium nitrogen, can have some inhibition on calcium in plants. At the same time, the calcium content of the root of rice has been significantly reduced under drought conditions. In addition, the utilization of soil moisture by plants has been significantly reduced with lower surface temperatures. The application ratio of n, p and k is to be reasonably adjusted according to the power of the earth and the state of production, with due regard to the application of trace elements such as ca, mg, b and zn. Through many years of production experiments, large-scale large shed tomatoes were found to be highly vulnerable to anthrax and to have caused considerable damage to their leaves. In the early stages of the infection, the leaves of the plant will first produce a circular necrosis, then turn gray, and the boundaries are clear, and the leaves will then merge together and become an irregular necrosis. The impact on plant root systems is also significant when disease is more severe in daejeon. Biochemical control is a safer response, and the effects of the use of pest intensification are more pronounced. The methods currently in use are cedar trapping and chalk trapping, which have a better effect on large areas of cedar baiting; and the use of colour disc baiting, which can effectively combat large black powdered and bees. In recent years, tomato facilities have grown rapidly, and disease prevention and control have become a widespread concern and some progress has been made. The use of biosafety techniques can significantly reduce the negative effects of pests on the surrounding environment and achieve effective protection of the surrounding environment. Increased prevention of disease and pests and the active use of biopesticides in the production of tomatoes in facilities will not only ensure the healthy growth of tomatoes, but also improve their growth quality and reduce environmental impacts. 3. 4 the environmental protection and ecological awareness of other pests is increasing, and a variety of new ecological control techniques have emerged in tomato cultivation. In the course of tomato cultivation, it is also necessary to change its own thinking and to proactively introduce ecological controls. (1) chemical control. In the context of the integrated management of pests and diseases, which is dominated by non-hazardous chemicals, it is important that farmers, when selecting pesticides, purchase cleaner, non-polluting ecochemicals from the market, not only to reduce the environmental pollution caused by pesticides, but also to ensure the safety of tomato products. (2) physical control. Safety is its most prominent feature, and it is a physical approach to pest and disease control that does not affect food safety or the ecological environment. In tomato greenhouses, the more common physical control method consists of a colour disk trap, which uses insect sensitivity to colour to induce and has a clear impact on the control of pests such as aphids and powdery bacteria. For example, anti-worm nets, which are protected from harmful biological intrusion by covering the greenhouses, do not interfere with light or air. There are also insect lanterns, which induce insects by lighting them, a light source that uses solar energy as a low-cost, effective and easy to replicate. (3) biological control. Biocontrol is a biotechnology-based integrated pest management approach, more representative of sexual inducements, which can effectively curb pest reproduction and reduce the number of harmful organisms in greenhouses. Insects such as grasshoppers, host cocoon bees and raviolis are used in greenhouses to combat pests such as twilight flies and white powder lice. (4) agricultural control. The use of agricultural science and technology to control pests, for example by regulating the density of cultivation, can reduce the incidence of pests; there is also field management to ensure healthy growth of plants by controlling the humidity, light, temperature and ventilation of greenhouses. In addition, the incidence of pests and diseases can be reduced through such measures as fusion, fallback and rotation. The occurrence of tremors is strongly related to tomato cultivation methods and cultivation conditions, such as high humidity and depth of cultivation. Infecting with tomato stem decomposition, the bottom of the trachea becomes brown, and then there's a white bulge on the rotting part, and there's an unsuspecting root that grows, leaves with yellow atrophy, although its roots generally do not rot and are not well controlled, and it slowly becomes a dark brown fungus. The selection of resistant plants is preceded by the laxation of the land before planting; the selection of a hot and hot shed with sufficient sunlight to achieve bacterial, insecticidal and disinfection effects; the mixing of the agents into the plant every six days, depending on the conditions, after planting; and the application of the agent to the root of the disease within a range of 2 to 3 metres. As the most important agent for tomato transmission, the tomato aging bacteria are characterized by infestation and the collection of insects on the back surface of the plant, the extraction of leaf surfaces, resulting in eutrophication of the leaves and, in serious cases, the death of the plant. Black sorghum is a highly reproductive, large group of pests whose adult pests and insects tend to consume large quantities of nectar, causing large areas of coal contamination, thus having a negative impact on the photocosy and breathing of tomatoes. Time-bound patrols, the timely removal of infested leaves and their centralization outside the huts can significantly reduce the origin of pests; they can also be booby-trapped in greenhouses or can be tied to lower the probability of their occurrence. 3. 5 the rational choice of the field of application to determine the scope of application of drugs can be a good incentive for the production of large greenhouse tomatoes, which, in terms of their growth and development characteristics, play a significant role throughout their development. However, overdependence on these substances is highly likely to produce pesticide residues, affecting the quality of facilities and the health of the population. In addition, most plant workers' practice of administration yes
