为了探索“五四○六”菌肥在水稻卷秧上的施用效果,我们于1971年、1972年在不同基点、不同品种上进行了一些试验,现将结果简报于后.一、“五四○六”菌肥在水稻卷秧上的施用效果据1971年在我院南场试验(品种“文光”),施菌肥三成与不施菌肥的对比,施菌肥的苗高增加25%,根多20.9%,百苗干重增长50%.1972年在吴忠县古城大队第三生产队试验(品种“京引39号”),施菌肥二成的比猪圈肥三成的苗高31.3%,百苗鲜重增加25.9%,百苗干重增长25%;同年在永宁县红星五队试验 In order to explore “5460 ” effect of the application of fertilizer on rice seedlings, we conducted some tests on different base points and different varieties in 1971 and 1972, and the results will be briefly introduced in the later. “5460” application of bacterial fertilizer in the rice roll seedling effect in 1971 in our hospital South Field test (varieties “Wenguang Fertilizer seedling height increased by 25%, 20.9% more root, a hundred seedlings dry weight increased by 50% .1972 in Wuzhong County ancient city brigade third production team test (cultivar ”Beijing No. 39"), fertilizer Zicheng 31.3% higher than that of the pigsty, the fresh weight of seedlings increased by 25.9% and the dry weight of seedlings increased by 25%.
