内蒙古呼盟农业科学研究所多保永等,于1996年在内蒙古呼伦贝尔大草原选择有代表性的鄂温克旗草库伦对栽培牧草和天然草地进行EM1号叶面喷施试验。一般草地和牧草(碱草、披碱草)喷洒的浓度以200—600mg/kg较为合适,每亩用最为30—70ml。偏碱性土壤,石灰性反应强,肥力高,EM1号的喷施浓度要提高。偏酸性肥力低的或沙性重的土壤,EM1号的喷施浓度应相应减少。灌木应高于多年生草本,多年生应高于1年生草本。生殖期应高于营养生长期,每亩牧草和草地喷施液
Inner Mongolia Hu Meng League Institute of Agricultural Sciences and more, in 1996 in Inner Mongolia Hulun Buir prairie selected representative eleven Kewenlun on cultivated pasture and natural grass EM1 foliar spray experiments. The general grass and pasture (Soda, Elymus) spraying the concentration of 200-600mg / kg more appropriate, with a maximum of 30-70ml per acre. Alkaline soils, strong lime reaction, high fertility, EM1 spraying concentration should be increased. Slightly acidic fertility or sandy heavy soil, EM1 spraying concentration should be reduced accordingly. Shrubs should be higher than perennial herbs, perennial should be higher than the annual herb. Reproductive period should be higher than the vegetative growth period, grass and grass per mu spraying liquid
