最近,我国对于合宜的深耕深度进行了广泛的研究。无疑的,这是一个极为重要的问题,但也是一个极为复杂的问题。一般对于这个问题的研究,主要是从深耕之后,对于土壤物理、土壤化学和土壤生物特性所引起的影响,以及对根系发育、分布的关系这个角度去进行的。在上述这些因素中比较直接的是根量分布。但是,根量和根系吸收强度之间,在很多情况下,并不是一致的。 Recently, our country conducted extensive research on the depth of appropriate deep plowing. Undoubtedly, this is an extremely important issue, but it is also an extremely complicated one. The general research on this issue is mainly from the point of view of the relationship between soil physiology, soil chemistry and soil biological characteristics, and the relationship between root development and distribution after deep plowing. Among these factors, the more direct one is the root quantity distribution. However, there is in many cases not the same between root volume and root absorption intensity.
