| 摘 要： | 分别用喷施宝、三效绿叶神、磷酸二氢钾、双吉尔-GGR6号4种植物生长剂对青海冷地早熟禾(Poacrymophila cv.Qinghai)、青海中华羊茅(Festuca sinensiscv.Qinghai)进行叶面喷施试验,结果表明,所施植物生长剂对2种牧草的丰产性均有不同程度的良好影响,其鲜草产量、种子产量和地下生物量均有提高;增产作用由大至小依次为:磷酸二氢钾三效绿叶神、双吉尔喷施宝。4种植物生长剂均适宜在牧草大田生产中推广使用,尤其是磷酸二氢钾增产显著,价格低廉,使用简便安全,应积极推广应用。

| Abstract: | Four kinds of plant growth agents (Penshibao, Sanxiaolvyeshen, KH2PO4 and GGR6) were sprayed on the leaves of Poa crymophila cv. Qinghai and Festuca sinensis cv. Qinghai respectively to study the effect on seed yield. The results indicated that 4 plant growth agents could increase the yield of the fresh grass, seed and underground biomass and the effect of KH2PO4 was the best. and it could be concluded that 4 agents could be extended for grass production. |
