土壤是由形状、大小不同的结构单位组成的多孔体。理想土壤要求有一定比例的各种孔隙,具有适宜的透水性,在根密集的土层中,空气和水分能自由流动,水肥气热协调,使作物根系获得良好的土壤环境,吃饱、喝足、住得舒服。人们通常以耕耙土地来进行灭茬,造成理想的土壤环境。但是,并非所有的耕耙都能促成良好的土壤环境,尤其是在土壤过湿状态下耕耙,反而会破坏土壤结构。现根据试验结果和调查资料,简要介绍
Soil is a porous body composed of structural units of different shapes and sizes. Ideal soil requires a certain percentage of various pores, with appropriate water permeability in the root-intensive soil, air and moisture can flow freely, water and fertilizer gas heat coordination, so that crop roots get a good soil environment, eat, drink Foot, comfortable living. People usually rake harrow land for stubble, resulting in the ideal soil environment. However, not all harrows can contribute to a good soil environment. In particular, harrowing soil under wet conditions can destroy the soil structure. According to the test results and survey data, a brief introduction
