增产菌对高寒地区燕麦产草量的增产效应

The effect of yield increasing bacteria on oat grass production in alpine region pasture

采用增产菌拌种、喷施２种方法的二因素随机区组设计，对燕麦草的增产效应进行了研究。结果表明，增产菌对燕麦的增产效果极显著（Ｐ＜０．０１），最佳拌种量为３００ｇ／ｈｍ２，最佳喷施量为３００ｋｇ／ｈｍ２。拌种和喷施增产菌对燕麦的增产效果是相互独立的，拌种与喷施的交互作用不显著（Ｐ＞０．０５），两者的增产效应是可加效应，最佳处理组合为３００ｇ／ｈｍ２拌种量＋３００ｇ／ｈｍ２喷施量。

The effect of yield increasing bacteria on oat fresh grass product was studied by seed dressing and spray administration in a bi factor random sampling block test. The results showed that the yield increasing effects was obvious (P<0.01). The most reasonable dose was 300 g/hm 2 for both methods. The two factors were independent each other, but mutual aid effect. Best match of combine usage was 300 g/hm 2 for the two methodes.
