Catalogue catalogue autumn plantation technology overview of varieties selection and plantation technology preparation and plantation technology for the collection and storage of fertilizers and pest management technologies, and risk analysis of autumn plantation technology the provision of healthy foods, orchids, is a nutritious vegetable, rich in vitamins and food fibres, and the development of the autumn orchid cultivation can provide more healthy foods for the market. The autumn to meet market demand is the main consumption season for the broccoli, and therefore knowledge and mastery of the farming techniques for the orchid can meet market demand and raise farmers ' incomes. The species that choose to grow broccoli in the autumn should choose those that are adaptable, resistant, productive and of good quality. The climatic conditions for planting broccoli in autumn under the basic condition 01 weather conditions are more stringent, requiring a cooler climate, high temperature during the day and night, high air moisture and good soil drainage. Soil conditions in which broccoli is grown in the autumn of soil conditions include soil fertility, organic abundance, good drainage and ph suitability. As consumer demand for quality of agricultural products improves, the planting of broccoli in the autumn will focus more on precision cultivation, improving product quality and production. As awareness of food safety and environmental protection increases, precision cultivation will become a trend for the development of the orchid plant in the autumn, improving product quality and safety. With the spread of the internet and the development of rural electricians, the marketing channels of the autumn broccoli will become more diversified, including online and offline sales, cooperative sales and wholesale marketing. The principles of the development of the autumn cultivation in diversified distribution channels, the selection of species for the autumn cultivation and the selection of varieties for breeding techniques, are adapted to the autumn climate, disease resistance, good commodities, and species for storage, such as excellence, green belts, etc. Appropriate varieties are selected according to the climatic characteristics and market needs of different regions, such as those of early maturity, which are suitable for cultivation in higher temperatures and those of late maturity, which are suitable for cultivation in lower temperatures. The choice of seedling beds for breeding techniques is intended to select flat ground, well-drained, soil-rich plots as seedbeds, the length of which should not normally exceed 10 metres, depending on the sowing volume and terrain. The seeding method is based on on-demand seeding, with 1-2 seedings per den at a depth of 0. 5-1 cm and a range of 15-20 cm and a range of 10-15 cm. The planting time is determined according to local climatic conditions and variety characteristics, and the normal planting time for fall planting is mid-july to early august. The temperature in the nursery bed shall be maintained at 25-30°c before the seedling is produced, and the temperature shall be reduced appropriately after the seeding, at 20-25°c during the day and 10-15°c at night. Temperature management of seedlings is followed by maintenance of about 70 per cent humidity in the nursery bed and proper fatting during growth, usually 2-3 times urea per acre and 5-10 kg urea per acre. Water fertilizer management is vulnerable to aphids and viral diseases during its fall season, and care is taken to prevent them by using agents such as aphids. Pest control03 field preparation and planting technology field selection 01 select soil fertile, well drained and organically rich plots to avoid re-cropping and rotation with cross-flower vegetables. Fields are prepared to fertilize the land at a depth of 02, tan, fertilize, apply decomposed organic fertilizer of 2000-3000 kg per acre, calcium per phosphate of 50-100 kg, ammonium sulfate of 20-30 kg and potassium chloride of 20-30 kg. Zirconium-03 is made up of 1. 5-1. 7 metres wide, 5-8 metres long flat or high, 30-40 cm wide and 15-20 cm deep, depending on the shape and size of the plot. Autumn planting is usually practiced from mid-july to mid-august. The seeding time is on-demand, with 1-2 seeds per den ranging from 40 to 50 centimetres and 30 to 40 centimetres. The sowing method is sowing at a depth of approximately 2 cm and then covers a thin layer of soil. During the growth of the broccoli, the in-depth planting technique, 03 fertilizers, is followed in due course, usually 2-3 times with urea or 10-15 kg compound fertilizer per acre. Post-plant management should be followed by timely watering and soil humid to facilitate seed sprouts and seedlings. Weeds are removed from the field in time to prevent competition with orchids for nutrients and moisture, either before or after the orchid. 04 fertilizer management techniques use decomposed organic fertilizers as base fertilizers to improve soil structure and increase soil fertility. Organic fertilisation is applied to the full range of nutrients in accordance with the nutritional needs of the broccoli over different periods of growth, with a combination of different ratios. Composite fertilizer application supplements trace elements such as boron, magnesium and calcium to meet the demand for trace elements in broccoli. Micro-element application of rational fertilization techniques during sowing water is used to water the bottom water before seeding, to ensure soil moisture and to facilitate seed germing and growth. Life and long-term water is distributed rationally, depending on weather conditions and soil moisture, to meet the moisture requirements for the growth of the broccoli. In times of drought, water should be watered more often and more in order to ensure normal growth of broccoli. Preventing the insatiable flooding of orchids should avoid over-watering leading to over-wetting of the soil so as not to affect root growth and disease. Attention should be paid to drainage during the rainy season and to the timely discharge of water in order to avoid the prolonged accumulation of water in the soil that hinders the growth of broccoli. Avoiding excessive fertilization may lead to problems such as burning seedlings and soil sheeting of broccoli, and the application of fertilizers should be controlled in appropriate quantities. Attention to fertilizer 05. The main pest and pest control techniques are the soft, rotting, stinking, and marginal diseases. The black scavenging orchids show round or irregular foliage, the edges are brown, the centre is light brown, the roots are bruised and black, and the later leaves atrophy. The bacterium nuclei plant has water stains on the base of the plant and later has white filaments and rat faeces. The larvae larvae eat the leaves, creating a “hole hole”, which can be eaten up when it is severe. The larvae larvae eat the leaves, resulting in hollowness or lack of carving, and can eat them all when they are severe. Black scrutinism enhances plant management, with attention to drainage and ventilation; spray control can be done with a combination of agro-sulphate salcin or copper hydroxide at the beginning of the disease. Select anti-pathological varieties; strengthen plant management, with attention to drainage and ventilation; spray control can be carried out with agricultural sulphate-chainicillin or copper hydroxide in the early stages of the disease. Timely removal of leaves left in the fields and reduction of bacterial sources; strengthening of plant management, with attention to drainage and ventilation; and use of agricultural sulphate chain carbide or copper hydroxide agents for spray control in the early stages of the disease. Controls such as biopesticides such as bacillus are used; spray control is also possible with chemical pesticides such as chlorocypermethrin. Controls such as biopesticides such as bacillus are used; spray control is also possible with chemical pesticides such as chlorocypermethrin. Treatment methods and measures to reduce environmental and human hazards through the use of vegetative moths, moths and fertilizers, strictly comply with the safety protocols for the use of pesticides and ensure the safe use of medicines; different pests and pests should be treated with different agents to avoid the creation of resistance; efficient, low-toxic and low-residency pesticides should be selected to reduce environmental and human hazards; and emphasis should be placed on the rotation of medicines to avoid the long-term use of the same agent. The harvest time of the harvest and storage techniques is approximately 150 days after the planting of the orchids, and the harvest time is better in the morning or evening than in the high temperature. The harvest method should cut off a mature flower ball on a plant and retain 3-4 leaves to maintain fresh and wetness. The harvest time and methods should be preceded by the sorting of the collected flower ball, the removal of the excess leaves and buds, and the washing of sludge and pesticide residues on the surface of the flower ball. The pre-treatment of broccoli has a suitable storage temperature of 0-1°c and a relative humidity of 90-95%, and therefore should be based on the choice of a well-ventilated, cool and humid storage to avoid direct sunlight and freezing. During storage periods, the storage period for storage conditions technology 1 storage period23 is subject to periodic inspection of the storage of broccoli, such as detection of infirmity, decay, etc., should be dealt with in a timely manner and the storage environment kept clean. To maintain the freshness and quality of the broccoli, a number of conservation techniques, such as membrane packaging, and the use of freshenware, are available. Preserve should first select orchids, remove undesirables and defectives, and grade them to increase the value of sales. The benefits and the quality of the analysis of the autumn pods in the autumn of coop07 are favourable to the improvement of the quality of the broccoli, such as vitamin c content and taste. The yield analysis market advantage in the autumn was a strong season for the sale of broccoli, with high market demand and better market prices. High-yielding autumn-planted broccoli can achieve higher yields at appropriate temperatures and light conditions. Climate change autumn is also a high-prevalence period for orchid pests, such as bacterial nuclei and aphids, which can affect the growth and production of orchids. The risk of fluctuations in demand in the pest and pest market analyses the demand for broccoli in the autumn market, although it may be large, but prices may fluctuate as a result of market demand and supply, with some market risk。volatility in the autumn may have an impact on the growth and development of broccoli, such as high-temperature droughts or cloudy humidity. Ways and means of increasing the benefits are the choice of good varieties for disease-resistant, reversible, high-yielding orchid varieties suitable for fall cultivation. Quality management strengthens field management, regularly fertilizing, watering, weeding, etc., and ensures a healthy environment for the broccoli. Pest control regularly inspects the growth of broccoli to detect and control pests and pests in a timely manner to reduce losses. Marketing strategies rationalize the timing of harvests and sales to achieve better economic benefits, depending on market demand and prices. Thanks thanks for watching
