增产菌是从植物根部筛选出来的一种植物保健益素。为了明确增产菌对旱粮作物的增产作用及其经济效益,1988年我们在本所对谷子、玉米、小麦等作物进行了试验,取得良好效果。一、材料与方法应用北京农大植保系生产的广谱性增产菌,在谷子、玉米、小麦上做了菌粉拌种(3％)、菌液拌种(2％)、拔节后叶面喷施10—50毫升/亩及菌粉拌种后再叶面喷雾等处理,小区面积0.01亩。
Increased production of bacteria is selected from the plant roots of a plant health benefits. In order to clarify the effect of increasing bacteria on the yield increase of dry grain crops and its economic benefits, we conducted experiments on crops such as millet, corn and wheat in 1988 and achieved good results. I. Materials and Methods The broad-spectrum growth bacteria produced by the Department of Plant Protection and Conservation of Beijing Agricultural University did powder dressing (3%), bacterial seed dressing (2%), foliar spray after jointing Shi 10-50 ml / acre and then powdery seed dressing and then foliar spray treatment, residential area of 0.01 acres.
