不同磷肥水平对退化苜蓿生产性能的影响
Effects of Phosphorus Fertilizer Levels on the Performance of Degraded Alfalfa
摘要
Abstract
In order to improve the yield of degraded alfalfa grassland and prolong the high yield period,the alfalfa planted 8 years ago in Dingxi City was fertilized in 2016. The results showed that the application of P fertilizer could promote the growth of alfalfa and increase the yield of fresh grass. When the amount of phosphorus fertiliger was 750 kg/hm2,the yield of fresh grass reached 24227.75 kg/hm2,the profit 7431.08 RMB/hm2.关键词
