Pepper is a crop that requires more fertilizer and has a larger amount of fertilizer. According to relevant research results, the production of 2,000 kilograms of pepper needs to absorb 10.38 to 11.60 kilograms of nitrogen, 1.16 to 2.20 kilograms of phosphorus, and 12.92 to 14.80 kilograms of potassium. Tests have shown that applying more nitrogen to adequate amounts of pepper, followed by potassium, phosphorus can be less. The fertilization schemes with more nitrogen, potassium, and phosphorus were 24.9% higher than the N, P and K ratios, and were 26.8% higher than nitrogen, phosphorus, and potassium.
Scientific and rational fertilization method, first of all to determine the soil in a variety of effective nutrient content, calculate the soil available components; and then will obtain a certain amount of nutrients needed to absorb the nutrient content of the pepper, minus the soil available for nutrition; finally according to different fertilizers Nutrient content and its absorption and utilization calculate the required application amount of NPK fertilizer. This is the more advanced soil testing formula fertilization. Where there is no condition for soil testing and where there are few farmyard fertilizers, in order to obtain high yield of peppers, we recommend that 50-60 kg of NPK fertilizer should be applied per acre, 50 kg of calcium magnesium phosphate fertilizer, 15-25 kg of urea, and potassium sulfate. Or potassium chloride 10 to 20 kg (or 200 kg of plant ash). The specific amount of fertilizer is based on the increase or decrease of soil fertility. Among them, calcium, magnesium and phosphate fertilizers have delayed effect, poor mobility in soil, and are easily fixed by soil. All of them should be basal fertilizers and be concentrated in furrows. The urea-burning roots are easily lost and only a small amount (usually 5 kg/mu) is used as base fertilizer. Potassium fertilizer is also very easy to lose, and pepper results in a large amount of potassium absorption. Potash fertilizer can promote fruit enlargement. Therefore, potassium fertilizer is mainly used for topdressing in the result period. Compound fertilizer is mostly used as base fertilizer. If the plastic film is covered and cultivated, more than 80% of the total amount is used as base fertilizer; 50% to 60% of the clay with good plasticity without covering the mulch is used as the base fertilizer, and 30% to 40% of the sandy soil is used as base fertilizer.
In addition to nitrogen, phosphorus and potassium, pepper also needs a variety of nutrients. Farmhouse organic fertilizers are completely nutritious and can also improve the soil, so it is better to use farmyard fertilizers for growing peppers. Without farmyard fertilizer, bio-organic fertilizer can be purchased. The active bacteria contained in it include nitrogen fixation, phosphate release, and potassium release, which fixes the free nitrogen in the air to the soil and converts the phosphorus and potassium that cannot be used by the crop in the soil. For the available state, the fertilizer has high efficiency and no pollution. After the application, the crop diseases and insect pests are reduced, and the yield and quality are improved. If the pepper is completely used with chemical fertilizers, in addition to conventional fertilization, foliar spray fertilizer is also required, mainly to supplement the boron and zinc it needs. , iron, copper and other trace elements, can choose to use high-yielding treasure, spray Shibao, plant power 2003, Guangzeng and other foliar fertilizers, spraying 3 times, generally increase production by 15% or more.
