Peanut bogey for continuous results
Peanut new planting is generally more than 20% more than continuous cropping, with a maximum yield of up to 40%. According to the survey, there are four major drawbacks to the continuous cropping of peanuts: causing a serious lack of soil. Peanut roots have a large number of rhizobia and are less sensitive to nitrogen. Due to continuous cropping, it leads to soil nutrient deficiency and can not meet the nutrients needed by peanuts, thus affecting the normal growth and development of peanuts, showing more and more serious deficiency of the disease. In addition, new glutinous crops generally do not have a deficiency. Cause serious pest damage. Peanut bacterial wilt, virus disease, root nematode disease, leaf spot disease, etc., are mostly transmitted by soil bacteria. The longer the continuous cropping period, the more the diseased plant body in the soil accumulates, and the higher the chance of peanut infection. However, peanuts planted in Xinyi are lightly or non-pathogenic. Affect their own absorption of nutrients. During the growth and development of peanuts, their roots continuously secrete more organic acids. Although this organic acid can dissolve the minerals in the soil, continuous cropping will accumulate organic acids in the soil. The extremely unfavorable soil environment caused by the growth of peanut roots affected the ability of peanut roots to absorb nutrients, resulting in short plants and poor disease resistance. The quality of peanuts is poor and the yield is low. Peanut continuous cropping, low fruit setting rate. Less fruit, small peanuts, and even pods, some experiments show that peanuts for two consecutive years, 8-10% reduction in production, continuous production for three years to reduce production 25-30%, continuous production for more than 50% reduction in four years.
