粘土具有某些必须克服的缺点,也有某些优点,有关这些优缺点的假定是研究粘土上谷物生产的基础。无论是优点或缺点,都能从粘土的结构或团聚体上找出其原因。粘土的耕性和有效利用,取决于具有良好性质的团聚体的形成。本文目的在于研究这种团聚体的形成与促进团聚化的土壤管理措施的关系。 Clay has some disadvantages that must be overcome, as well as certain advantages. Assumptions about these advantages and disadvantages are the basis for the study of grain production on clay. Whether it is a merit or a weakness, it can be found from the structure or aggregate of the clay. Tillage and efficient use of clay depend on the formation of agglomerates with good properties. The purpose of this paper is to study the relationship between the formation of such aggregates and the soil management measures that promote reunification.
