Vegetable production in large gardens is “scientific management”, and many vegetable farmers suffer from poor production, frequent figs, deformations, death of yellow leaves, frequent disease, not because of varieties and weather, but mostly because day-to-day management is inherently flawed. Many people grow their vegetables with experience, which appears to be carefully guarded and expensive, and they step on the pits, which eventually leads to a long gap, lower yields and reduced revenues. Today, the sheds are being summed up to grow six high-frequency lethal error zones, to dismantle faulty practices, to profile hazards, to combine highly ground-based circumvention techniques and to help vegetable farmers to avoid pits and produce more productively。
One: the more fertilizing, the better. Production
This is the most common area of error in the cultivation of the sheds. Many vegetable farmers consider the shed to be a high-input, high-output mode, and want the vegetables to grow fast and guacamole to be applied blindly and in large quantities to organic, compound, water-solar, frequent flushing and overstretching, knowing that the shed environment is closed, hot and wet, that fertilizer is decomposition much faster than in open fields, and that over-fertilization not only does not increase production, but can cause multiple problems。
Insinuation of the roots after the salinization has been exceeded in the soil has led to the prevention of suction of the roots of vegetables and to the burning of roots, smothering of roots and decaying roots and the planting of plants in the form of yellow leaves, rigid seedlings and a weakening of the strength. This can also result in soil clinking, acidification, salinization, the breeding of nematodes and endemic diseases. It can also cause problems such as the growing of plants, the failure to produce results, the fall of flowers and the malformations of fruit, with higher inputs and lower yields。
Pipe avoidance techniques: old sheds (growing for more than three years) strictly control fattening, control of organic fats such as rotting cattle and sheep dung within 2,500 kg per acre, reduction of fertilizer use by half and avoidance of blind pursuit of fat. For salinized plots, fertilizers, em microcosm, bio-organic fertilizers, improved soil structure, pine gas, desalinization. At the same time, micro-elements such as boron, zinc and magnesium are supplemented, as required, to balance soil nutrients, avoid single fertilization, and achieve a steady production of uplifts。
Erection 2: the higher the temperature, the faster the temperature, the better the room
Most vegetable farmers mistakenly assume that the core function of the sheds is to keep warm, and that the higher the temperature of the vegetables grow faster, especially during the winter and low-temperature seasons, in order to prevent freezing, to keep the wind closed all day, to deliberately raise the temperature of the shed and not to cool at night, is typical of the mismanaged approach. Each vegetable has an exclusive growth temperature, with most vegetables at 25-32°c and shed temperatures longer than 35°c, inhibiting growth。
At high temperatures, the respiratory effect of vegetables increases significantly, nutrient consumption goes well beyond the accumulation rate of photosynthesis, strains are physiologically disturbed, and problems with long leaves, long sections and thin leaves are extremely high. At the same time, it can have a serious impact on the fracturing of flowers, resulting in low drops, drops, sits and increased deformities. What is more subtle is the high night temperature, which continues to consume nutrients, resulting in a shortage of nutrients, which directly leads to late production cuts。
Pipe avoidance techniques: implementation of a day and night temperature differential management method, 25-30°c for daytime temperature control, temperature exceeding the temperature mark to open the upper and lower vents in time for cooling; reasonable temperature control at night to maintain 10-15°c to reduce nutrient consumption. Accumulation of nutrients based on a finely adjusted temperature for vegetables, growing stages, suitable low-temperature seedlings during the seeding period, steady temperature during the expansion period and elimination of high-temperature shacks throughout the period。
Wrong zone three: the higher the yield of seedlings, the higher the output, the higher the output of the forest, the higher the output of the seedlings, the higher the output of the seedlings, the higher the output of the seedlings, the higher the output of the seedlings, the higher the yield of the seedlings, the higher the output of the seedlings, the higher the output of the seedlings, the higher the output of the seedlings, the higher it is, the higher it is, the higher the output of the trees, the higher it is, the higher it is, the higher it is, the more it's the same
In order to make the most of the space in the shed, a number of vegetable farmers have deliberately increased the density of their cultivation and the availability of seedlings, regardless of the light of the shed and the limited ventilation conditions, which constitute one of the greatest obstacles to high productivity. In particular, poor winter and spring light, low temperatures, inefficient photosynthesis and low nutrient synthesis can only be counterproductive。
Over-stretching can lead to extreme ventilation in the field, foliage and the inability of lower foliage to photocooperative use, as well as high humidity in the shed, with frequent incidences of frosty, greyy, powdery and bacterial diseases. At the same time, there is a competition for water fattening and light among plants, with mixed overall growth, an increase in the number of small and vulnerable seedlings, a decrease in the number of flowering results, a small yield, an uneven colour and anomalous appearance, and a significant decline in overall production and quality。
Pipe avoidance techniques: maintain rational thinning and limit density of vegetable varieties and sheds to eliminate blind planting. Using the dynamic management model of “pre-enhancement, mid-term defoliation, post-foliation”, long-term and timely defoliation of weak, ill and redundant branches ensures that the leaves are not crowded, ventilated, and that the nutrients are concentrated in the supply of strong plants and fruits。
The bigger the better, the better the better
Many vegetable farmers judge whether vegetables are growing well or not, depending on whether the leaves are thick or not, and believe that a strong cyanide is a sign of high productivity, high fattening of the daily management of the water, which is not managed in a timely manner and which leads to excessive nutrition and delayed reproductive growth. Vegetable growth cores are “nutrient growth and reproductive growth balance”, and excessive foliage takes over the vast majority of nutrients, resulting in inadequate nutrients for flowers。
When the plant is grown, its roots are shallow, resistant, prone to inversion and disease, along with problems such as low flowering, fruit differentials, fermentation and slow expansion, and the phenomenon of “crazy, uncupplied and low yield”. In particular, fruits such as tomatoes, cucumbers, peppers and eggplants have been the cause of severe losses due to the loss of production caused by schoolmasters。
Pipe avoidance techniques: sapling is done during the sapling period, water control is moderate, rooting is promoted, seedlings are nurtured and shallow seedlings are avoided. Long-term dynamic regulation of long-term long-term growth, with a prior guarantee of a reasonable area of leaves, a medium-term balance between nutrition and reproductive growth, and an end-stage focus on chicken promotion, leading to concentration of nutrients towards flowering results. The timely removal of redundant swabs, invalid side branches, old leaves at the bottom and reduced nutrient consumption。
Zone five: the less the spray gets, the more the blind high frequency
The large sheds are prone to disease in a very wet and closed environment, and some vegetable farmers are caught in the misdirection of “drinking, multi-drinking” and sprayed every two to three days, with or without the disease, even with a combination of a variety of agents, which is considered to be a complete prevention. The use of blind high-frequency medications is not only ineffective but also raises a range of problems。
Frequent use of drugs can lead to resistance to bacteria, with post-mortem outbreaks without specific drugs; it can also cause damage to vegetable leaves and flowers, causing drug damage and causing problems such as yellow-haired leaves, flowers and fruit spots. Long-term overdose also destroys the ecological environment in the shed, inhibits plant growth, reduces the resilience of the vegetables themselves, creates a vicious circle of “drugs and diseases”, and leads to excess pesticide residues that affect the quality of vegetables。
Pit avoidance techniques: at the heart of the disease is the improvement of the shed environment, timely ventilation, wetting, rational lighting and the reduction of disease from the source. The principle of “pharmaceuticals, pre-preventives, rotational drugs” is upheld, prevention is carried out periodically in the absence of disease, the disease is identified with precision, the medication is targeted, and blind mixing and high-frequency spraying is avoided. Land-borne diseases focus on soil improvement, sterilization during seeding, prevention of root causes, rather than reliance on later spraying。
Zone six: the more you get, the more you get. Land
In order to maximize the use of the shed resources, most vegetable farmers have opted for year-round multi-cropping, and the land has been inactive for a long time, with the perception that the more frequent, the higher the income. However, long-term re-emergence is one of the core causes of the fall in production and the high incidence of disease. Cultivation of the same vegetables over the years can lead to an imbalance in soil nutrients, the depletion of trace elements, the accumulation of soil pathogens and eggs over the years, and an increase in soil salinization and clinking problems。
Long periods of heavy planting, the roots of vegetables are chronically in poor soil conditions, with long-term weakness and extreme resistance, with the death of a dead seedling, endemic diseases and root worms increasing year by year, and the problem of “more poor and less productive”, even with increased water fattening and pharmaceutical inputs, it is difficult to recover the loss of production。
Pipe avoidance techniques: rational planning of pits, winterization of winter, and spring and autumn of spring are recommended for each year to avoid over-cropping and intensive cultivation. Every summer, free periods are set aside to provide for the improvement of soil and the improvement of the capacity of the soil to be fertilized, dry up the soil, rain-fed salt, suffocated vermin. Rotation, cropping of guacamole and leaves and vegetables has been introduced to ease the obstacles to land connections and to achieve sustainable production。
Summarizing: science avoids pits
The core of the high production of large-scale vegetables has never been blindly and empirically high, but rather has circumvented fault lines and scientific precision management. Fertilizers, temperaments, cultivation, growth, medicine, mouths, and the six management lines can effectively reduce the problems of yellow leaves, dead trees, flowers, malformations, diseases, etc., significantly reduce the risk of production reduction, steadily increase the production and quality of vegetables, and easily increase the yield。
