随着双季稻的发展,冬季绿肥紫云英成为我区早稻的当家肥。但一肥两稻的耕作制度远不能满足两季水稻对肥料的需要,目前晚稻产量不高,肥料不足是主要原因,特别是缺乏有机肥。因此需在大力积制农家肥,并努力提高紫云英单产的同时,积极发展夏季绿肥,开展早稻间种田菁的试验研究工作,以解决晚稻基肥,推行两稻两肥制,用地 With the development of double cropping rice, the winter green manure asparticum became the first manure of early rice in our region. However, the farming system of one paddy and two rice far can not meet the needs of two-season rice for fertilizer. At present, the yield of late rice is not high and the shortage of fertilizers is the main reason, especially the lack of organic fertilizer. Therefore, it is necessary to make vigorous efforts to produce farmyard manure and make efforts to raise yields of wild shiyuning. At the same time, we should actively develop green manures in summer and carry out experimental research on farming cyanines in early rice to solve the problem of late rice basal fertilizer,
