氮磷肥配施对一年生黑麦草生长性能及产量的影响
Effects of Combined Application of N and P Fertilizer on Growth Performance and Yield of Annual Ryegrass
摘要
Abstract
This experiment was conducted to study the effects of combined application of nitrogen and phosphorus fertilizer on the growth performance and yield of annual ryegrass.The results showed that the effect of applying phosphorus fertilizer without N(N0)was not obvious.Under the condition of low nitrogen(N150),phosphorus treatment can significantly increase the yield compared with no phosphorus treatment.Under the condition of high nitrogen(N300),the yield of N300P90 experimental group was significantly higher than that of N300P0.The yield of annual ryegrass can be significantly increased by applying nitrogen fertilizer at different phosphorus application levels.Under the conditions of combined use of nitrogen and phosphorus,the ratio of N300P180 treatment had the best effect,which could improve the growth indexes of ryegrass,such as the number of leaves,tillering number,plant height and apparent leaf area,but the yield was not significantly different from that of N300P90 group.The above results showed that the combined application of N and P fertilizer could improve the growth performance and yield of ryegrass,and the comprehensive yield,growth performance and economic benefit of N300P90 was the best.关键词
