间混套种是我国 传统的耕作方法之 一。它具有悠久的历史,早在西汉《汜胜之书》的“区种瓜法”里,就介绍在瓜区中间种薤和小豆的技术。北魏《齐民要术》中还介绍,在葱中间作胡荽(香菜),大麻田里间作芜菁,树荫下种蘘荷,桑树下套种芜菁子,以及在楮树、槐树育苗时,同麻子一起撒播等等。随着现代农业科学的发展,间混套种技术进一步完善,已成为解决我国人多、地少、提高单位面积产量、进行集约化经营的重要途径之一,对农业增产起着愈来愈大的作用。 间混套种为什么能增产,它有什么好处呢? Inter-mixed farming is one of the traditional farming methods in China. It has a long history, as early as the Western Han Dynasty “Book of Wisdom” of the “species of melon law”, introduced in the middle of melon area and the adzuki bean technology. The Northern Wei Dynasty “Qi Min Yao Shu” also introduced in the middle of the onion as a cilantro (coriander), marijuana intercropping turnip, shade under the Dutch, mulberry intercropping turnip seedlings, as well as tree, Sophora japonica seedlings , Sow with pockmarked and so on. With the development of modern agricultural science, the technology of interplanting intercropping has been further improved and has become one of the important ways to solve the problems of overpopulation, less land and more yield per unit area for intensive management in our country. It is playing a more and more important role in increasing agricultural output effect. Why inter-mixed inter-species production increase, what is the benefit of it?
