低丘红壤氮磷配比施用对黑麦草产量和植株养分累积的影响

Study on the Yield and Nutrient Accumulation in Lolium Perenne with Multiple-ratioUsing of N─P Fertilizer in Low Hill Red Soil Region.

研究结果表明，在低丘红壤上氮、磷单施，氮肥效果大于磷肥，而氮磷肥配比混施又优于单一施用；植株体内养分的含量和累积，随施肥量的增加而递增。

The study result shows that the efficiency of N fertilizer is higher than that of p─fertil-izer p─fertili and highest efficiency is achieved when using both N─and p─fertilizerswith multiple-ratio amount.The nutrient content in the plant increases with theamount of the fertilizars applide.
