What is the principle of fertilizing peanuts?
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.

Simple Identification of Peanut Leaf Blight
Peanut net spot, also called moire spot or reticulate spot, was first discovered in America in the mid-1940s. In the late 1970s, Liaoning Province of China reported the occurrence and damage of this disease for the first time. In recent years, the disease is more common in northern production areas of China, and the damage is serious. Generally, the yield is reduced by about 20%, and the serious yield is reduced by 4%.

Occurrence and control of peanut bacterial wilt
Peanut bacterial wilt, commonly known as "green disease", "dead seedling", "plague" and "dead vine", is an important disease in peanut producing areas. The incidence rate of general plots is 10%-25%, and the incidence of serious plots is more than 50%. Peanut bacterial wilt is a typical vascular disease, which can occur in the whole growth period of peanut.
