What are the hazards of peanut continuous cropping?

What are the hazards of peanut continuous cropping? Please introduce the harm of peanut continuous cropping as follows: 1. It causes serious soil deficiency. Because the root of peanut has a large number of rhizobium, it is not very sensitive to nitrogen. Due to continuous cropping, the soil is lack of elements and can not meet the nutrients needed by peanuts, thus affecting the normal growth and development of peanuts. The longer the continuous cropping, the more serious the deficiency. On the other hand, there is generally no deficiency in the new stubble. 2. It causes serious harm to diseases and insect pests. Peanut bacterial wilt, virus disease, root nematode disease, leaf spot disease, etc., mostly due to the transmission of soil bacteria, the longer the continuous cropping time, the more diseased plants accumulated in the soil, the higher the probability of peanut post-infection. On the other hand, the peanut planted in the new stubble has a mild or no disease. 3. Affect their own absorption of nutrients. In the process of peanut growth and development, its roots continue to secrete more organic acids. Although these organic acids can dissolve minerals in the soil, continuous cropping will inevitably lead to excessive accumulation of organic acids in the soil, resulting in a very unfavorable soil environment for the development of peanut roots, affecting the ability of peanut roots to absorb nutrients, making the plants short and poor in disease resistance. 4. resulting in poor quality and low yield of peanuts. Peanut yield and quality are affected because of low fruit setting rate, low full fruit rate, small or even shrunken peanut kernels in continuous cropping. The experiment shows that the yield of peanut has been reduced by 8% to 10% for two years, by 25% to 30% for three years, and by more than 50% for more than four years. For this reason, peanuts should have high yield and improve quality, and farmers should practice crop rotation instead of continuous cropping.
