摘要
利用不同施用量的增产菌，在牧草各生育期分别进行１次、２次、３次叶面喷施，对其增产效应进行了观察研究。结果表明，增产菌对高山禾草型草地牧草具有明显的增产效果，最佳施用量为１５０ｇ／ｈｍ２，施用期为禾草拔节期，施用次数为１～２次，增产幅度为１６．７５％～２４．９％。
Using different amount of Zengchanjun applied to spray one on leaf, two and three times in every growth stage, its increasing yield effect was studied. The results showed that it had significantly increasing yield effect on alpine grasses, the optimum amount applied was 150 g/hm 2 ,and applied in jointing period, the applied times were one to two, the yield increased by 16.75% to 24%.
