怎样解决冬种紫云英的留种问题,我们曾经进行过多方面的摸索。近三年来,利用稻底秋植甘蔗地间种紫云英留种,获得了良好效果。1973年甘蔗地间种的紫云英春收种子亩产只有17.5斤,1976年达到66.5斤。大队党支部及时推广了这个经验,全大队共有甘蔗地376亩,1975年冬就有311亩间种了紫云英留种,基本上改变了从外地调种的状况,降低了生产成本,促进了农业生产的发展。间种紫云英留种不会影响甘蔗产量最初,我们曾耽心间种紫云英留种会影响主作甘蔗的产量,为了得出正确的结论,就专门进行了调查研究和对比试验。1974年收获
How to solve the problem of the remaining species of winter millet, we have conducted many exploration. The past three years, the use of autumn rice planting sugarcane ground intercropping species of milk vetch, get good results. In 1973 the sugarcane variety of Astragalus mongolicum seed yield per spring only 17.5 kg, 66.5 kg in 1976. The brigade party branch promoted this experience in a timely manner. The entire brigade has a total area of 376 mu of sugar cane. In the winter of 1975, there were 311 mu of interspecific alpine shrubs in the area, which basically changed the status of planting seeds from the field, reduced the production cost and promoted The development of agricultural production. Intercropping of Astragalus sepals will not affect the production of sugarcane Initially, we have been worried that the intercropping of Astragalus sinicus will affect the production of main sugar cane. In order to draw the correct conclusions, we conducted a special investigation and comparative experiments. Harvested in 1974
