摘要
主要讨论了钾肥对紫花苜蓿的影响,试验证明,紫花苜蓿产量虽因钾肥的释放量增加而增加,但是当钾肥投放量达到150 kg·hm-2后增产效果不再明显。钾肥可以在紫花苜蓿刈割后起到稳产的作用,对紫花苜蓿中粗纤维合成的影响最为显著。
This paper mainly discusses the influence of potassium fertilizer on alfalfa, the experiment proves, alfalfa yield although potassium release was increased, but potassium quantity reaches 150 kg· hm^-2, yield increasing effect is no longer obvious, potash fertilizer in alfalfa cutting after the effect of potassium fertilizer on the yield, the effect of crude fiber of alfalfa in the synthesis is the most significant.
