众所周知,当前作物栽培中,土壤是绝大多数作物生长的基质、依托,是农业生产的基础。作物生长所需的水、肥、气、热及扎根条件都要通过土壤来供给,也就是说,土壤实际上是个由根系、微生物、水肥气热等诸因子构成的一个生态体系,其为植物生长供应和协调水分、空气、热量的能力影响着植物的全部生育进程,从而在很大意义上决定了作物的收成。而土壤的这种供给和协调功能来源于其最基本的结构单位——团粒结构。 As we all know, the current crop cultivation, soil is the vast majority of crop growth matrix, backing, is the basis of agricultural production. The water, fertilizer, gas, heat and rooting conditions needed for crop growth are supplied through the soil. That is to say, the soil is actually an ecological system made up of various factors such as root system, microorganism, water and fertilizer, The ability to grow and supply water and to coordinate the moisture, air and heat affects the entire plant growth process, which determines the crop yield to a great extent. The soil supply and coordination of this function comes from its most basic structural unit - aggregate structure.
