为了探讨二晚稻田长期板田直播造成红花草低产和旱期直播红花草难的问题,我区从1983年至今年进行了二晚稻田翻耕播种(单播与混播)绿肥与板田直播绿肥的对比试验,效果较好,并已逐步推广。翻耕播种的红花草冬天生长缓慢,冬苗真叶数、分枝数、主茎长均比板田直播的红花草低10～17％,但立春后翻耕播种的红花草比板田直播的生长迅速,根量、根长、根瘤大小和个数、主茎粗、主茎长、分枝数和鲜草产量等都有显著增加。据1987年4月10日的测定结果:翻耕播种的比板田直播的根
In order to discuss the problem of low yield of safflower grass and direct sowing of safflower grass during the two-night long-term rice paddy field broadcast, we conducted two nights of late-tilling sowing (unicast and mixed-sowing) green manure and BEDA live green manure from 1983 to this year The comparative test, the effect is better, and has been gradually promoted. Tillable safflower grass grow slowly in winter, the number of true leaves of winter mulberry, the number of branches, the main stem length of 10-17% lower than the flat-field direct safflower grass, but after the spring tillage planting safflower grass than the Bieta broadcast The growth of roots, root length, nodule size and number, main stem diameter, main stem length, branch number and fresh grass yield all increased significantly. According to the results of the April 10, 1987 determination: the root of tillage planted than that of Takeda
