早稻—晚稻—小麦的一年三熟制,在福建种植面积逐步扩大.而稻稻麦三季中,以晚稻较缺肥,为迅速提高晚稻产量,开辟新的肥源,两年来,我们开展水稻套种绿肥的试验研究,以探索几种绿肥对晚稻的增产效果,为推广提供依据. In the three years of early rice-late rice-wheat, the planting area in Fujian gradually expanded, while in the third season of rice and wheat, the late rice was more deficient than fattening, in order to rapidly increase the output of late rice and open up a new source of fertilizers, in the past two years, Intercropping green manure experiment research to explore the effect of several green manures on late rice yield, provide the basis for the promotion.
