针对农田复种指数下降,粮食播种面积逐年下滑,种植效益低,粮食缺口大的现状,我们研究推广农田一年三熟水旱轮作的新模式及配套技术,推广的春大豆-晚稻-萝卜种植模式,提高了农田复种指数,使有限土地资源、温光资源得到充分利用。实行水旱轮作,秸秆还田、用养结合,改善了农田生态环境,使各季作物丰产增收,从而达到农田稳粮增效。
In view of the decline of cropland multiple cropping index, the sown area of grain sown year by year, the low benefit of planting and the large grain gap, we studied and promoted the new mode and supporting technologies of crop rotation and crop rotation in a year, promoted the planting pattern of spring soybean-late rice-radish , Raising the crop multiplication index so that the limited land resources, Wen light resources are fully utilized. The implementation of crop rotation, straw returning, combined with the use of raising and improving the ecological environment of farmland so that all seasons crop yield, so as to achieve stable grain efficiency of farmland.
