Comprehensive yield-increasing effect of changing stubble in Sesame rotation

First, the exudates of sesame roots can promote the reproduction of microorganisms in the soil, accelerate the decomposition of organic matter in the soil, improve soil fertility, effectively raise the land, and increase the yield of the following crops. The second is to increase the per unit yield of sesame significantly. In the continuous cropping land, the average dead seedling in the initial flowering stage of sesame is 41.1%, and there is no dead seedling in the non-continuous cropping land; the average infection rate in the mature continuous cropping land is 79.2%, and that in the non-continuous cropping land is 1.34%. The output of non-continuous cropping increased by 29% in one year and 80% in two years. In production, it is better to "plant two kinds of sesame seeds for 4 years" (not to plant sesame seeds at an interval of 2 years), and the rotation of flood and drought is better.
