紫云英是我省一种主要绿肥,也是一项最主要的有机肥源。近年,由于三熟制的发展,紫云英的种植面积逐步在缩小,部分地区的单位面积产量不高。因此,必须从多方面采取措施,尽快提高紫云英的单产,为农业生产提供更多的肥料。几年的试验研究证明,菌肥拌种是一项经济有效的丰产措施之一,从不少试验结果看,增产幅度还不小。 Astragalus is a major green manure in our province, but also one of the most important source of organic fertilizer. In recent years, due to the development of three-cropping system, the area planted by Astragalus sinicus has been gradually reduced, and the yield per unit area in some areas is not high. Therefore, measures must be taken from various aspects to raise the yield of Astragalus as soon as possible and provide more fertilizers for agricultural production. Years of experimental studies have shown that bacterial fertilizer dressing is a cost-effective one of the measures to yield high yield, from many test results, the rate of increase is not small.
