Please introduce the fertilization method of sweet pepper with long growing period, underdeveloped root system, few roots, shallow soil penetration, drought tolerance and waterlogging tolerance. It needs more fertilizer than tomato and eggplant, and has strong fertilizer tolerance. The fertilizer requirement of sweet pepper was the highest in potassium absorption, the second in nitrogen and the lowest in phosphorus. Sweet peppers in vegetables.

How to fertilize sweet pepper can increase production? Please introduce the fertilization method of sweet pepper with long growing period, underdeveloped root system, few roots, shallow soil penetration, drought tolerance and waterlogging tolerance. It needs more fertilizer than tomato and eggplant, and has strong fertilizer tolerance. The fertilizer requirement of sweet pepper was the highest in potassium absorption, the second in nitrogen and the lowest in phosphorus. Sweet pepper belongs to the type of high nitrogen and medium high potassium in vegetables, which needs more fertilizer. Therefore, attention should be paid to the adequate supply of nitrogen, phosphorus and potassium in production in order to increase the leaf area and improve the photosynthetic capacity of leaves. In this way, vegetative growth can be coordinated with reproductive growth, neither the "little old seedlings" caused by the stagnation of vegetative growth, nor the "crazy seedlings" with long stems and leaves. When young fruits are mainly harvested, it is appropriate to increase the potassium nutrition level and make the ratio of nitrogen and potassium equal to 1 or slightly more than 1, which is of great significance to improve fruit quality, including commodity quality and nutritional quality. In addition, the calcium nutrition of sweet pepper should not be ignored, once the lack of calcium is easy to make the fruit navel rot, resulting in a great reduction in fruit quality. Fertilization skills: (1) choose vegetable garden soil with high organic matter content and good aggregate structure on seedling fertilizer, apply 150-200 kg mature organic fertilizer (treated by Gymboree starter) and 2-3 kg superphosphate evenly with bed soil every 10 square meters. If the seedlings grow slowly, the leaves are narrow, the stems are thin and the leaves are yellow, 1.0 kg of ammonium sulfate or nitrogen, phosphorus and potassium compound fertilizer can be applied with water 15-20 days before planting, or 2-3 foliar sprays containing 0.5% urea and 0.5% potassium dihydrogen phosphate aqueous solution. (2) the origin of sweet pepper on base fertilizer is tropical, and it grows in the environment of warm and humid climate and rich and loose soil for a long time. It has the characteristics of underdeveloped main root, shallow root distribution, mild temperament and large fertilizer demand. Therefore, the application rate of base fertilizer is very important for the high-yield cultivation of sweet pepper. The amount of high-quality organic fertilizer applied per mu should reach 5000Mu 7000kg. Base fertilizer can be used as pigsty manure, human manure, chicken manure and soil manure, etc. But no matter what fertilizer is used, it must be fully mature, it is best to use Gymboree starter treatment, and pay attention to the combined application of phosphorus and potassium. Calcium superphosphate is mixed into organic fertilizer according to 35Mu 50kg per mu, and 30kg of potassium sulfate can also be mixed. The application method of base fertilizer is to sprinkle 60% base fertilizer before soil preparation, and then trench according to row spacing and apply the remaining 40% when planting. The combination of spreading and furrow application can avoid the phenomenon of burning seedlings due to the concentration of fertilizer, which is beneficial to the development of seedlings. (3) topdressing should be carried out for 3 times. The first topdressing was carried out after slow seedling, ditching and topdressing near the plant, high-quality organic fertilizer was applied in the ditch, and then covered with soil, then watering was properly controlled in order to squat seedlings and promote root development; the second topdressing was carried out in the full fruit stage. before the first layer of fruit (door pepper) is harvested, the second layer of fruit (to pepper) and the third layer of fruit (four doors) continue to expand and the fourth layer of fruit is shedding flowers and fruits, it is the peak period of fertilizer. At this time, nitrogen fertilizer and appropriate amount of potash fertilizer should be applied, urea 10Mel 13 kg or ammonium sulfate 23 Mel 28 kg, potassium sulfate 12 Mel 15 kg; the third topdressing should be carried out in the middle and later stage of harvest, applying human feces and urine (or livestock and poultry manure) every 8 min 10 days, or appropriate amount of chemical nitrogen fertilizer, the amount should be determined according to the plant growth at that time, and pay attention to the combination with irrigation. (4) the application of biological fertilizer contains not only a large number of active bacteria for nitrogen fixation, phosphorus solubilization and potassium solubilization, but also organic matter, humic acid and trace elements. In any fertilizer period, sweet pepper can be combined with other fertilizers, which can not only save the amount of fertilizer, but also solve the problems of soil consolidation and increase the content of soil microorganisms.
