In agricultural production, heavy stubble is a common phenomenon, and the problem of peanut stubble has always plagued farmers. Peanut stubble can lead to an increase in the number of pathogens and pests in the soil, which can affect the growth and yield of peanuts. So, how to solve the problem of peanut recropping?Below we will analyze and ** from multiple aspects.
1. Reasonable crop rotation.
Crop rotation is an effective way to solve the problem of heavy cropping. In crop rotation, peanuts can be rotated with other crops, reducing the number of pathogens and pests in the soil. In addition, different crops have different nutrient uptake in the soil, and crop rotation can promote the balanced absorption of nutrients in the soil, which is conducive to the growth and yield of peanuts.
Second, the selection of disease-resistant varieties.
The selection of disease-resistant varieties is another important measure to solve the problem of peanut recropping. Disease-resistant varieties have high disease resistance and adaptability, which can reduce the occurrence of flower diseases, thereby reducing the risk of diseases caused by heavy cropping. In addition, the selection of disease-resistant varieties can also improve the yield and quality of peanuts, and increase farmers' profits.
3. Strengthen field management.
Field management is an important part of solving the problem of peanut cropping. Before planting, the soil can be deeply turned and sun-dried to reduce the number of germs and pests in the soil. During planting, multiple tillage and weeding can be carried out to promote root growth and nutrient uptake of peanuts. After harvesting, the fields can be cleaned and disinfected to reduce the residue of pathogens.
Fourth, scientific fertilization.
Scientific fertilization is one of the important measures to solve the problem of peanut cropping. In fertilization, organic fertilizer should be the mainstay, supplemented by chemical fertilizer, and trace elements should be appropriately supplemented. Organic fertilizer can improve soil structure, increase the number of beneficial microorganisms in the soil, and promote the growth and yield of peanuts. At the same time, appropriate supplementation of trace elements can also enhance the disease resistance and adaptability of peanuts.
5. Biological control.
Biological control is a safe and effective way to solve the problem of peanut recropping. By introducing beneficial microorganisms, the number of pathogenic bacteria in the soil can be reduced, thereby reducing the incidence of flower diseases. In addition, beneficial microorganisms can also promote nutrient cycling and decomposition in the soil, which is beneficial for the growth and yield of peanuts.
In summary, comprehensive measures are needed to solve the problem of peanut cropping, including reasonable crop rotation, selection of disease-resistant varieties, strengthening field management, scientific fertilization and biological control. Only by fully implementing these measures can we effectively reduce the risk of peanut stubble and improve the growth and yield of peanuts.
