1980～1981年,我县部份公社,采用西瓜棉花间作、套播油菜秧的栽培方式。80年,全县瓜棉间作、套播油菜秧的面积只有100多亩;81年发展到1350多亩。据调查,实行间套作后,能合理配置作物的群体,更好地利用空间地力和日光能,从而实现了瓜棉双高产,还解决了油菜专用秧田,一举三得。 (一)间套作的利弊 From 1980 to 1981, some communes in our county used the intercropping of watermelon cotton and the cultivation of oilseed rape. In 80 years, the whole county melon intercropping, cover sowing rapeseed area only 100 mu; 81 years to 1350 mu. According to the survey, after the implementation of the intercropping, the group of crops can be rationally allocated to make better use of space and solar energy, thus achieving double high yield of cucumber and cotton and also solving the problem of special seedling for rape.
