Guiding Opinions on Scientific Fertilization of Pepper in Spring
1. The principle of fertilization (1) to increase the application of high-quality organic fertilizer according to local conditions. (2) controlled fertilization at flowering stage, from flowering to branching and fruit setting, fertilization should be controlled except that the plant is seriously short of fertilizer and can be slightly applied with quick-acting fertilizer, so as to prevent falling flowers, leaves and fruits. (3) in order to promote the rapid expansion of young fruit, quick-acting fertilizer should be applied in time in young fruit stage and harvest period. (4) from transplanting to pre-flowering stage, pepper should be combined with promotion and control, and be watered frequently with thin fertilizer. (5) avoid using high concentration fertilizer, avoid wet soil topdressing, avoid topdressing at high temperature at noon, and avoid concentrated topdressing. 2. The amount and proportion of fertilizer application (1) the high-quality farm manure is used as base fertilizer at one time. (2) the yield level is below 2000 kg / mu: nitrogen fertilizer (N) 10kg / mu, phosphate fertilizer (P2O5) 3kg / mu, potash fertilizer (K2O) 8kg / mu; yield level 2000kg / mu: nitrogen fertilizer (N) 15kg / mu, phosphate fertilizer (P2O5) 4kg / mu, potash fertilizer (K2O) 10kg / mu The yield level is more than 4000 kg / mu: nitrogen fertilizer (N) 18kg / mu, phosphate fertilizer (P2O5) 5kg / mu, potash fertilizer (K2O) 13kg / mu. (3) 20% to 30% of the total nitrogen fertilizer is used as base fertilizer, 70% to 80% as topdressing; phosphate fertilizer is all used as base fertilizer; 50% to 60% of the total potash fertilizer is used as base fertilizer, and 40% to 50% is used as topdressing. (4) in the middle stage of pepper growth, we should spray 500 times foliar boron fertilizer and foliar calcium fertilizer to control pepper navel rot.

High-yield cultivation techniques of Capsicum in Spring, Summer and Autumn in greenhouse
At present, the main problems in production are mainly production in early spring, less production in autumn after removal of plastic film in summer, listing of vegetables in open field after summer, relaxed management, and low yield of pepper in the later stage. In order to maximize the production role of greenhouse facilities, the author guides the masses to carry out a big stubble planting in spring, summer and autumn.
