Small pepper is actually a popular name for the pepper clustered in pepper. Because it is small and grows in the sky, it is also used to being called Chaotianjiao or Chaotianhong. It is a way for farmers to get rich. However, due to continuous planting and extensive management, the yield and quality of peppers have declined. Through experimental research and observation and analysis in recent years, it is believed that only by cultivating the four key technologies of strong seedlings, formula fertilization, Dae Jingjing, and disease prevention and treatment can we increase production and increase income. First, nurturing and strong seedlings Seed beds should be leeward, sunny, fertile, and irrigated. General planting 667 square meters Daejee should prepare 8 square meters of bed curtains, apply 150kg per seedbed, 0
.5kg of decayed manure, 0.1kg of urea, 1kg of phosphoric acid of potassium dihydrogen phosphate, and mix the soil with fertilizer. General seedbeds should be 20cm above the ground. Water should be poured before sowing and sprayed with 75% chlorothalonil 600 times. At the time of sowing, seeds that had been soaked with seeds were evenly sown on the surface of the bed, and then covered with 0.5 cm of fine clay, then bowed and covered. Small capsicum is a thermophilic crop, the suitable growth temperature is 17-30 °C, and the optimum temperature is 20-25 °C. Seedlings should be kept at 25-28°C before arching, and in principle the seedlings should be lower than about 5°C before emergence so that the seedlings can grow robustly and enhance their cold resistance and disease resistance. "Two-leaf and one-heart" seed bed insulation measures should keep up, if the temperature continues to be low, the flower bud differentiation will be blocked, resulting in serious early flowering and fruit drop. At noon on sunny days, the temperature of the seed bed is very high, and it is advised not to expose large ventilation and prevent the seedlings from wilting or dying due to the large temperature difference and excessive water loss. Timely seedlings and removal of weeds, sick bodies, spraying once every 10-15 days 50% carbendazim 800 times. About one week before transplanting, all thin-film curing seedlings were removed. Second, soil preparation and formula fertilization fine soil preparation, full base fertilizer. According to the determination of the Chinese Academy of Agricultural Sciences, the required fertilizer for peppers is N:P:K=1:0.29:1.59. According to this feature, deep plowing at the beginning of winter is 20cm. After thawing in early spring, 3,500kg of farmland fertilizer and 25% of diammonium phosphate are applied. 15kg of potash, 20kg of urea, 0.5kg of zinc fertilizer and 400kg of boron fertilizer, or 46kg of urea 60kg, 16% of superphosphate 50kg, 50% of potassium sulfate 90kg. After shallow plowing, dig a small ditch every 2m to facilitate drainage. Third, the field management technology seedlings field planting 7 days before and after every 667 square meters with urea 5-7kg, boron 1kg, gibberellin 5g, root rot 15 bags, these drugs, fertilizers, auxins mixed together, with water Diluted pouring Miao Tian, ​​so that the roots thick and well-developed, root disease-free infection. When small pepper seedlings grew to 12 true leaves, they were selected for sunny day transplanting. The row spacing was 3045 cm. After the planting and survival, shallow pods were used once. Afterwards, the rain was used for shallow ploughing. The initial fruit period was combined with cultivator for soil cultivation, so that a small ditch was formed between the rows, which was conducive to fall prevention, drainage and reasonable top dressing. When cultivating soil, 667 square meters of urea 5kg, diammonium phosphate 5kg, ternary compound fertilizer 7.5kg, if the leaves appear a slight physiological yellow, with 0.3% potassium dihydrogen phosphate plus 1% urea mixed spray about 2 times, you can restore . Diseases and Pests Control The main disease of pepper is virus disease. There are four symptoms: mosaic, yellowing, necrosis and deformity. Due to persistent high temperature and drought in recent years, the early yellowing and late deformity of the small pepper is the most prominent. The typical symptoms and the most effective prevention and treatment method is: yellowing, the diseased plant turns yellow from the tender tip, and then a large number of fallen leaves, fallen flowers, and fallen fruit appear. . If a diseased plant is found in the field, it is promptly mixed with tycophora and capsicum and then added with 40% omethoate 1500 times, 0.3% potassium dihydrogen phosphate and 1% urea for 5-7 days. Co-spray three times, the symptoms disappeared, the plant returned to normal growth; deformity, diseased plant deformation, such as the leaves become linear, that is, fern leaves, or plants dwarf, branching very much, was plexiform. With potassium permanganate 750 times plus 0.3% potassium dihydrogen phosphate 0.1%, zinc sulfate spray every 5-7 days 1 times, a total of 3 times, the control effect of more than 90%.
