搞好农作物的间作、套种和混播,可以有效地争取生长季节,经济利用土地,充分利用空间,增加产品种类,提高作物产量,对解决作物争地矛盾和增加单位面积收入有着十分现实的意义。合理的间、套、混作,可以年年获得增产,但不合理的间、套、混作反而会造成减产,甚至招致土壤肥力下降或者破坏。这些方面,前人曾有个研究和作了一些理论性的
Intercropping, intercropping and mixing of crops can effectively improve the growing season, utilize land economically, make full use of space, increase product variety and increase crop yield. It is of great practical significance to solve the contradictions of crops and increase unit area income. Reasonable intercropping, mixing and blending can increase production every year. However, irrational intercropping, mixing and mixing will actually result in a decrease in production and may even lead to the decline or destruction of soil fertility. In these areas, there have been previous studies and made some theoretical
