摘  要:
本文研究了氮磷钾不同配比施肥量对黑麦草和紫花苜蓿混播草地牧草生长的影响,结果表明:氮肥促进禾本科牧草叶的生长(P<0.05),增施钾肥对禾草的生长有利;磷能促进豆科牧草根的生长(P<0.05)且豆科牧草株高随着施磷量的增加各处理间差异显著(P<0.05),高氮抑制豆科牧草的生长;最高产量的施肥方式:N:P_2O_5:K_2O为20:30:20,比对照处理的草地产量增加63.92%。

摘  要:
The experiment was conducted on the mixture grassland, i. e. Lolium perenne L. and Medicago sativa L. with the NPK difference matching and the effects of fertilizer on the grass and leguminous grass growth were observed. The results showed that N fertilizer accelerated the grass growth (P< 0.05 ), adding K fertilizer was beneficial to the grass growth ; P fertilizer was able to accelerate the growth of leguminous grass root (P<0.05) and the plant height of leguminous grass varied as the changes of P fertilizer usage (P<0. 05), the higher N fertilizer restrained the growth of leguminous grass. The fertilizer composition of the highest yield was N: P_2O_5: K_2O= 20: 30: 20, and the yield was higher over 63.92% than the control.
