近年来土壤肥力下降已成为发展我区农牧业生产的重要障碍之一,尽管施入一定量的化肥,但化肥的增产幅度明显下降。主要原因是豆科等养地作物的种植比例逐年下降,麦类作物重荏于连作比例逐年增加所致。为了扭转这种被动局面,加强土壤培肥方面的研究工作,实行粮草轮作,大力推广绿肥,对促进我区农牧业生产的稳步发展具有重要的现实意义。
In recent years, the decline of soil fertility has become one of the most important obstacles in the development of agriculture and animal husbandry in our region. Despite the application of a certain amount of fertilizers, the yield increase of chemical fertilizers has obviously dropped. The main reason is that the planting proportion of legumes and other farmland crops is declining year by year, and the proportion of wheat crops re-growing in successive years is increasing year by year. In order to reverse this passive situation, to strengthen soil fertility research, to implement crop rotation, to promote green manure, to promote the steady development of agriculture and animal husbandry in our region has important practical significance.
