对两种一年生禾草喷施增产菌的效果进行了研究，结果表明，叶面喷雾可促进燕麦的生殖生长，籽实提前成熟２～５ｄ，籽实产量比对照提高２１．７％，纯增收３２５．５０元，产投比为６．１∶１．０；高粱鲜草产量比对照提高２９．０％，纯增收５８６．５０元，产投比为１０．１∶１．０。拌种＋叶面喷雾对燕麦分蘖有促进作用，可明显提高鲜草产量，纯增收最高可达２５３．５０元，产投比最高可达４．３∶１．０。 The results showed that foliar spray promoted the reproductive growth of oats. The seeds matured prematurely for 2 ~ 5 days and the seed yield increased by 21.7% and the pure yield increased by 325% compared with the control. 50 yuan, production to investment ratio of 6.1: 1.0; sorghum fresh grass production increased 29.0% over the control, net income of 586.50 yuan, production to investment ratio of 10.1: 1.0. Seed dressing + foliar spray can promote the tillering of oats, which can obviously increase the yield of fresh grass. The net yield can reach as high as 253.50 yuan and the production-input ratio can reach as high as 4.3:1.0.
