There are "four major characteristics" in the growth of peppers - hi-light is afraid of strong light; hi-temperature is afraid of high temperature; hi-wet is afraid of phlegm; Therefore, the field management of pepper in the middle and late stages should be done in the following four points: First, rational fertilization The basic principle of pepper topdressing is “controlling nitrogen, stabilizing phosphorus, and supplementing potassium with potassiumâ€, as follows: Light application Before the pepper is slowed down to flowering, fertilization can promote the robust growth of the planting seedlings, and lay a good foundation for the flowering result. In this period, the topdressing fertilizer is mainly composed of compound fertilizer. 2. Stable application of initial fruit fertilizer Before flowering until the first harvest, the main role of fertilization is to promote the branching, flowering and fruit setting of the pepper plants. Topdressing is mainly based on nitrogen, phosphorus and potassium compound fertilizers, generally 5 to 10 kilograms per mu; 5 kilograms of boron fertilizer can be added per acre to increase the fruit setting rate; when 50% of the plants are budded and 20% of the plants are flowering When topdressing, 3 to 8 kg of urea per mu is applied; when 50% of the plants result, the application of potassium sulfate compound fertilizer is about 6 kg, which promotes fruit expansion; watering is repeated every 3 to 4 days after topdressing, avoiding water volume. Too large, timely cultivating, weeding, and soiling after watering. 3. Heavy application of fruit fertilizer The peak of the pepper entering the fire is the period of maximum fertilizer demand during the whole growing season. Fertilization is mainly based on nitrogen, phosphorus and potassium compound fertilizers, 10-15 kg per mu, increasing potassium fertilizer in an appropriate amount, about 3 kg per mu, and using a certain amount of micro-fertilizer; under normal circumstances, watering should be timely after each fertilizer application. It promotes the absorption of nutrients by peppers, improves the utilization rate of fertilizers, and also increases the humidity in the field, which is conducive to flowering and fruit setting. 4. Late fattening In the later stage, root top dressing can be used, and 0.1% urea, 0.2%-0.3% potassium dihydrogen phosphate and other micro-fertilizers can be used. Second, cultivating and weeding In the middle stage of pepper growth, due to watering, fertilization, rainfall and other agricultural operations, it is easy to cause soil compaction and lyrical damage. Before the ridge is closed, the membrane should be cultivated in time to promote the deep growth of roots and prevent premature senescence; the depth and range of cultivating should not be damaged. The root system is prevailing; in general, timely watering after cultivating soil is beneficial to the growth of pepper; the elimination of weeds is beneficial to the vegetative growth and reproductive growth of pepper; the field management of pepper during the whole growth period is well done, the plant grows robustly, and the resistance is relatively strong. Enhanced, pests and diseases are less harmful, can reduce the number of medications, reduce production costs, increase production, and the quality of peppers can also be improved. Third, the prevention of pests and diseases The diseases of peppers mainly include diseases, bacterial wilt, and viral diseases. The disease can be used with anti-virus cockroaches, toxic worms, manganese Zn, garnipin, Phytophthora, etc.; in the early stage of the disease, 72% of agricultural streptomycin 0.25 ‰ liquid, bactericidal 0.25 ‰ liquid, etc. can be used for irrigation. 100-150 ml of liquid medicine, once every 7 to 10 days, and then irrigated 2 to 3 times; virus disease can be sprayed with 20% virus spirit 2 sputum at the seedling stage, and sprayed a second time after colonization. Spray for the third time, at the same time pay attention to the control of aphids, because the aphids are the media to spread the virus; the main pests of the peppers are aphids, small tigers, tobacco budworms, sassafras, etc., 2.5% deltamethrin, 10% again Net, 1% insecticide, 73% gram, etc. Fourth, timely harvest Most of the peppers are eaten with green tender fruits, so they can be harvested as long as they grow to a certain size; but green peppers are most suitable when the peels are dark green, hard and shiny; the early fruits should be harvested early to avoid affecting them. Plant growth; harvesting in the middle and late fruit to a certain maturity to improve quality and yield; harvesting of dried peppers should be harvested when each red pepper reaches 60% to 75%, and the whole plant is picked up at harvest. Every 3 to 6 strains are tied into small bundles and placed in a cool place to be dried. After all the peppers are dried, they are picked, stored, graded and sold.
