从90年代开始,针对我区绿肥生产大幅度下降,传统有机肥主源不足的现状,我们抓住稻草大量过剩的有利条件,在全区广泛开展稻草还田试验、示范和推广应用工作,先后抓试验点6个,示范0.13万公顷,1996年推广面积增加到21.3万公顷,增产粮食5千吨。实践证明,我区多年来大力推广稻草还田,方法多样,简便易行,行之有效,潜力很大,是充分利用过剩秸秆资源,增辟有机肥源,保护土壤肥力,增强农业后劲的有效途径。 Since the 1990s, in response to the drastic drop in green manure production in our region and the shortage of traditional organic fertilizers, we have seized the favorable conditions for excess straw and conducted extensive experiments in the fields to test, demonstrate and popularize straw work. Grasp the pilot six, demonstrating 130000 hectares, in 1996 to promote an area of ​​213000 hectares, an increase of 5 tons of food. Practice has proved that our region has vigorously promoted straw to the field for many years and has diversified methods. It is simple, feasible, effective and has great potential. It is to make full use of excess straw resources, increase organic fertilizers, protect soil fertility, and enhance the effectiveness of agricultural stamina way.
