套种是一种农业增产措施,在华北等地区得到广泛的应用,它主要是利用两种或两种以上的作物交替生长,以充分利用生长季节、地力和光能,从而可以提高粮食总产量。在省科委的支持下,我院从1975年开始,由农学系为主,进行了以早熟品种为内容的套种两熟的研究,收到了增产、增收、增细粮的初步效果。农机系于76和77两年配合进行了套种两熟机械化的研究,基本上解决了生产过程机械化的问题。
Interplanting is an agricultural stimulation, widely used in North China and other regions. It mainly uses two or more crops to grow alternately to make full use of the growing season, soil fertility and light energy so as to increase the total grain output. With the support of the Provincial Science and Technology Committee, our institute started from 1975 and was mainly engaged in agronomy. The research on the intercropping of two crops with early maturing varieties was carried out, and the initial results of increasing production, increasing income and increasing fine grain were received. In the two years of 76 and 77, the Department of Agricultural Mechanization conducted the research of mechanization of interplanting double ripening and basically solved the problem of mechanization in the production process.
