摘要
随着生态农业和畜牧业的发展,寒地牧草的种植正在以迅猛的速度发展,而牧草施肥相对比较落后。通过试验表明:牧草专用肥可以促进禾本科牧草的生长发育,使其地上部分生长迅速。N10P5K3表现最好,株高73.7 cm,增高9.8 cm。N10P5K3增产幅度最大,鲜草增产18 486 kg.hm-2,增产率为77.0%;干草增产8 433 kg.hm-2,增产率为78.7%。每kg肥料增产最高的是N10P5K3为61.62 kg,增加了47.9 kg,产投比也最好为5.60∶1。所以N10P5K3是寒地禾本科牧草生产的最佳施肥配方。
With the development of ecological agriculture and stockbreeding,the acreage of pasture has increased rapidly in Frigid Zone. In this experiment, the results showed that special fertilizer on pasture could accelerate the development of gramineous pasture. N10P5K3 indicated the best effect, the plant height was 73.7 cm,increased 9.8 cm than that of control. N10P5K3 indicated the best yield result,biomass yield increased 18 486 kg · hm^-2 ,increase rate was 77.0% ;dry yield increased 8 433 kg· hm^-2, increase rate was 78. 7%. N10P5K3 increased yield 61.62 kg per kilogram fertilizer, increased 47.9 kg than that of control. N10P5K3 was the best fertilizer,the rate of product to invest was 5.60 ： 1. That was to say N10PSK3 was the best for the production of gramineous pasture.
