随着一年三熟耕作制度的不断发展,如何进一步发扬自力更生精神,大力开辟肥源,解决农业生产发展所需的肥料,成为一个迫切需要研究的课题。近年来,我们经过学习兄弟省关于冬种绿肥单播改混播的先进经验,在省内组织了二十多个点,开展红花草(即紫云英)、黄花油菜、白花萝卜菁的三花混播高产试验示范,取得了可喜收获。大面积的三花绿肥亩产都有6000-8000斤,高的有一万多斤,比单播紫云英亩产增加30％-50％,有的达一倍以上,为今后提高冬种绿肥产量展示了广阔的前景。三花混播对发展农业的作用
With the constant development of the three-year farming system, how to further develop the spirit of self-reliance and vigorously develop fertilizers to solve the fertilizer needs for the development of agricultural production has become an urgent issue to be studied. In recent years, after studying the advanced experience of Brother Province on the unicast-mixed broadcast of winter-type green manure, we organized more than 20 points in the province to carry out three kinds of flowers, namely red flowers (ie, Chinese milk vetch), yellow flowers, white radish Mixed-cropping high yield test demonstration, has made gratifying gains. A large area of three green fertilizer per mu have 6000-8000 pounds, high of 10,000 kilos, higher than the unicrafted Purple Acre production increased by 30% -50%, and some more than doubled, for the future to improve winter green manure Production shows a vast future. The role of Sanhua mixed broadcasting in the development of agriculture
