改良土壤结构是提高土壤肥力的主要措施,增加土壤中的团粒结构,就能增加土壤含水量和抗旱能力,解决土壤中水和空气的矛盾,有利于土壤中有机物的分解,提供植物能吸收的养分。增加土壤团粒结构的方法,除了多施有机肥料,实行草田轮作外, Improving the soil structure is the main measure to improve the soil fertility. Increasing the aggregate structure in the soil can increase the soil water content and drought resistance, solve the contradiction between water and air in the soil, facilitate the decomposition of organic matter in the soil and provide the plant with energy absorption nutrient. Methods to increase soil aggregate structure, in addition to more organic fertilizer, the implementation of rotation of grass field,
