| 摘 要： | 对青引1号燕麦采用不同施磷处理，探讨不同施磷对其饲草产量和蛋白产量的影响，找出最佳的施磷量，为青海省燕麦饲草生产提供了理论依据。结果表明：青引1号燕麦在不同施磷处理下，总分蘖数、株高无显著变化。在施磷量90kg／hm^2时有最大有效分蘖数（2．00个／蘖），在施磷75kg／hm^2时有最大茎粗（0．584cm）。青引1号燕麦在施磷量60kg／hm^2，乳熟期收获时可获得较高的饲草产量（29855．0kg／hm^2）。青引1号燕麦在施磷量75kg/hm^2，开花期收获可获得较高的蛋白产量（2177．2kg／hm^2）。各时期饲草产量和蛋白产量（Y）与施磷量（P）的数量关系均可用Y=a＋bp＋cP^2表示。

| Abstract: | The different phosphate fertilizer level were applied to Qingyin No l oat to discuss the effect of the phosphate fertilizer level on hay gras yield and protein yield of oat,and find the optimum phosphate fertilizer content and give the theoretical basis of oat hay grass production in Qinghai provincl.The results showed that the total tillers and the plant height were no significant change when the different phosphate fertilizer level were applied to Qingyin No l oat.The maximum availability tillers of Qingy... |
