紫云英是我省主要的冬种绿肥作物,一般每亩可产鲜草2—3吨,既可有效地解决农田有机质来源,又能为畜牧业提供良好的青饲料,是实施沃土工程、促进农业可持续发展的措施之一。从生产实践看,种植紫云英对发挥晚季杂交稻增产优势,防止早衰有着明显的作用。但是,近年来种植势头低落,鲜草产量较低,种植面积明显滑坡,撰写此文希望引起重视。 Astragalus is the main winter planting green manure crops in our province, usually 2-3 tons of fresh grass per acre can effectively solve the source of organic matter in farmland, but also for livestock husbandry to provide a good green feed, is the implementation of fertile soil project to promote One of the measures for sustainable development of agriculture. From the perspective of production practice, the planting of Astragalus sinicus has the obvious effect of giving play to the advantage of increasing yield of late season hybrid rice and preventing premature aging. However, in recent years, the planting momentum is low, the yield of fresh grass is low and the area under cultivation is obviously declining. This article is hoped to attract attention.
