Peanuts are crops that bloom on the ground and are underground. Due to the unique characteristics of peanuts, the production is obviously characterized by low flowering rate and high shell rate. Practice has proved that in peanut cultivation, how to fertilize properly and create soil conditions that are favorable for peanuts after flowering is the key to improving the seed setting rate of peanuts. The "three-in-one" fertilization method is introduced below for reference.
Organic fertilizers combined with chemical fertilizers. In order to improve the effective nutrients of the soil and form a plough layer structure with Panasonic, gas and water coordination, it is necessary to adhere to the combination of organic fertilizer and chemical fertilizer in the type of fertilization. Organic fertilizers not only contain richer and more complete nutrients, but also organic matter that can improve soil structure. Chemical fertilizers contain a single nutrient element and a high nitrogen-fast nutrient content. The combination of the two can promote each other, improve fertilizer efficiency, improve soil structure, continuously fertilize soil and mature the cultivated layer.
Base fertilizer combined with topdressing. Peanut flowering period is the period of strongest root-absorbing capacity and the highest amount of fertilizer absorption. Therefore, all or most of the fertilizer needed for high-yield peanuts should be combined with winter ploughing and early spring cultivating land as base fertilizer and seed fertilizer application. If the base fertilizer is insufficient and no fertilizer is applied, the fertilizer can be properly applied. However, the time for top dressing is early, usually before the flowering period. In order to promote the fullness of the pods in the middle and late stages of growth and development, root dressing can be carried out.
The front sputum is mainly combined with the scorpion supplement. Peanuts are called "sweet" crops, which are straight roots and deep in the soil. They absorb deep nutrients. They also leave a portion of the fixed nitrogen to the soil for use by the lower crops. The residual roots of peanuts and the return of stems and leaves to the fields can significantly improve soil fertility. However, most of the nutrients needed for high-yield peanuts come from the soil. Therefore, under moderate to high ground conditions, the application of sorghum fertilization is better than that of peanut. The relevant tests showed that when the sweet potato was planted in the former, and the peanut was planted in the latter, the total fertilization amount of the sweet potato was the highest when the total fertilization amount of the two crops was the same, and the yield increased by more than 20% compared with the non-fertilizer. Before the peanut, the sweet potato was applied to the whole fertilizer, which was about 12% higher than that of the whole fertilizer. On the basis of pre-fertilization, when the peanuts are planted, the fertilizer should be properly added. Although the peanuts have lower absorption and utilization of the applied nutrients, the yield increase effect is moderate at moderate fertility levels because it can compensate the output consumption. Soil nutrients. All in all, the high-yield fertilization of peanuts must be based on the principle of “being combined with nutritionâ€.
Peanuts are used as a method of fertilization. According to the absorption of nitrogen, phosphorus and potassium nutrients and the absorption and utilization rate of fertilizers under high-yield peanuts, under the general conditions, the method of fertilization of nitrogen halving, phosphorus doubling and potassium can be used, that is, 13.5 kg of nitrogen per acre, phosphorus 11 Kg and potassium 16 kg, equivalent to 5000 kg of high-quality ring fertilizer per acre, 13 kg of urea or 35 kg of ammonium bicarbonate, 72 kg of superphosphate, 22 kg of potassium sulfate or 18 kg of potassium chloride or 150 kg of ash. In the case of medium or low soil fertility conditions, to achieve high yield, the "nitrogen and potassium application, phosphorus fertilizer double application" fertilization method can be used, that is, 27 kg of nitrogen per mu, 11 kg of phosphorus, and 16 kg of potassium, equivalent to each 5,000 yuan of high-quality ring fertilizer, 42.5 kg of urea or 115 kg of ammonium bicarbonate, 72 kg of superphosphate, 22 kg of potassium sulfate or 150 kg of potassium oxide or plant ash.
