我们常说的菌肥,是一种用工业方法生产的根瘤菌剂,每克菌剂含根瘤菌活菌数3～5亿个。施用菌肥是一项简便易行、经济效益高的增产措施。 据我站调查,花生施用菌肥每亩增产荚果约30斤;菌肥可使大豆每亩增产二十斤左右;应用于牧草,每亩可多牧干草150～180斤。应用菌肥的亩投资很少,农作物为0.3～0.4元,牧草为0.1～0.2元,而每亩直接经济效益为6～14元。
We often say that the fertilizer, is an industrial production of Rhizobium agents, bacteria per gram of bacteria containing Rhizobium 3 to 500 million viable cells. Application of bacteriostat is a simple, economical and efficient stimulation measures. According to my station investigation, the peanut application of fertilizer per acre yield pods about 30 pounds; bacterial fertilizer can increase soybean yield about 20 pounds per mu; used in pasture, mu Mu Mu hay can be 150 to 180 pounds. Mu fertilizer application of fertilizer little, 0.3 to 0.4 yuan for crops, pasture 0.1 to 0.2 yuan, while the direct economic benefits per acre 6 to 14 yuan.
