Last Updated: 2024/11/05, The main results are as follows: (1) Farm manure is the main and chemical fertilizer is the auxiliary. In China, peanuts are mostly planted in hilly areas, with thin soil layer and low fertility. Farm manure is mainly organic fertilizer, which is rich in nutrients, which can improve soil, fertilize and fertilize the soil for a long time. Chemical fertilizer is a quick-acting fertilizer, although it also contains the nutrients needed by peanuts, but with.

The main results are as follows: (1) Farm manure is the main and chemical fertilizer is the auxiliary. In China, peanuts are mostly planted in hilly areas, with thin soil layer and low fertility. Farm manure is mainly organic fertilizer, which is rich in nutrients, which can improve soil, fertilize and fertilize the soil for a long time. Chemical fertilizer is a quick-acting fertilizer, although it also contains the nutritional elements needed by peanuts, but compared with farm manure, the nutritional composition is still single. At the same time, there are other residual components in the process of chemical fertilizer application, which is not conducive to the growth of peanut and the improvement of soil fertility. (2) the combined application of organic fertilizer and inorganic fertilizer interacts with each other to improve the activation of microorganisms in the soil and the decomposition rate of organic fertilizer, so that various nutrients can be absorbed by peanuts, thus improving the utilization efficiency of fertilizer. (3) full amount of nitrogen and potassium and double of phosphorus. For every 50 kg peanut pods, the ratio of nitrogen, phosphorus and potassium is 5, 4, 4 and 2.5. The utilization rates of nitrogen, phosphorus and potassium fertilizers for peanuts in the current season were 41.8% / 50.4%, 15% / 25% and 45% / 60% respectively.
