“5406”菌肥经在全国范围内大面积的使用,证明它具有提高土壤肥力、促进作物生长和抗病驱虫等作用,只要菌肥质量高,施用得法,均有明显的增产效果。为了进一步探讨“5406”菌肥在甘肃省一些地区的应用效果和应用方法,我们从1973年起,以春小麦为试验材料,分别在兰州、靖远、武威等地进行试验。在几年的试验中,不论从植株的长势或籽粒的产量来看,凡是施用了“5406”菌肥的均有显著的效果,一般增产在10％—30％左右。这个增产幅度和全国全省其他各地所做的肥效试验基本上是一致的。
Large-scale application of “5406” bacterial fertilizer has proved that it has the effect of increasing soil fertility, promoting crop growth and disease-resistant insect pest. As long as the quality of bacterial fertilizer is high and its application is effective, it has obviously increased yield. In order to further explore the application effect and application method of “5406” fertilizer in some areas of Gansu Province, we started from 1973 with spring wheat as test materials and conducted experiments in Lanzhou, Jingyuan and Wuwei. In several years of experiments, no matter from the growth of the plant or the yield of the grain, any application of the “5406” bacteriostat has a remarkable effect, generally increasing the yield by about 10% -30%. This rate of increase and other parts of the province throughout the fertilizer efficiency test is basically the same.
