Pepper is a crop that requires more fertilizer and a larger amount of fertilizer. According to the relevant research results, the production of 2000 kg of pepper requires absorption of nitrogen 10.38 ~ 11.60 kg, phosphorus 1.16 ~ 2.20 kg, potassium 12.92 ~ 14.80 kg. Tests have shown that the application of nitrogen to pepper should be applied in an appropriate amount, followed by potassium and phosphorus. Fertilization schemes with more nitrogen, potassium and less phosphorus increased yield by 24.9% compared with NPK, and increased yield by 26.8% compared with nitrogen, phosphorus and potassium.
Scientific and rational fertilization method, firstly, to determine the various effective nutrient contents in the soil, calculate the soil available nutrient content; then the nutrient content of the pepper that is obtained for a certain yield, minus the soil nutrient content; finally, according to different fertilizers The nutrient content and its absorption and utilization rate are calculated from the application amount of NPK fertilizer. This is the more advanced soil testing formula fertilization. Where there is no condition for soil testing and there is very little farmyard manure, to obtain high yield of pepper, we recommend that 50-60 kg of NPK fertilizer should be applied per mu, 50 kg of calcium magnesium phosphate fertilizer, 15-25 kg of urea, potassium sulfate. Or 10 to 20 kg of potassium chloride (or 200 kg of ash). The specific amount of fertilizer applied is based on the increase or decrease of soil fertility. Among them, calcium magnesium phosphate has a slow effect, is poorly mobile in the soil, and is easily fixed by the soil. It should be used as a base fertilizer and concentrated in the ditch. Urea easily burned roots and easily lost only a small amount (usually 5 kg / mu) as a base fertilizer. Potassium fertilizer is also easy to lose, and the pepper absorbs potassium in a large amount during the fruiting period. Potassium fertilizer can promote fruit expansion, so potassium fertilizer is mainly used for topdressing in the fruiting stage. Compound fertilizer is mostly used as a base fertilizer. If it is covered by plastic film, more than 80% of the total amount is used as the base fertilizer; 50% to 60% of the sticky soil with good mulch is used as the base fertilizer, and 30% to 40% of the sandy soil with leakage is used as the base fertilizer.
In addition to NPK, peppers also require a variety of nutrients. The farmer's organic fertilizer is completely nutrient, and it can also improve the soil. Therefore, it is good to apply the farmer's fertilizer. If there is no farmyard manure, bio-organic fertilizer can be purchased. The active bacteria contained in it have the functions of nitrogen fixation, phosphorus dissolving and potassium decomposing, that is, the free nitrogen in the air is fixed in the soil, and the phosphorus and potassium which cannot be utilized by the crop in the soil are transformed. In order to be available, the fertilizer efficiency is high, no pollution, the crop pests and diseases are reduced, the yield and quality are improved after application. If the fertilizer is completely used, in addition to conventional fertilization, foliar spray fertilizer is needed, mainly to supplement the boron and zinc it needs. , iron, copper and other trace elements, you can choose high-yield treasure, spray Shibao, plant power 2003, Guangzengsu and other foliar fertilizer, spray 3 times, generally increase production by more than 15%.
