摘要:
本试验采用回归设计, 研究草原施肥后对牧草产量及质量的影响, 并对牧草生产进行经济效益分析, 结果表明:草原施肥是草原增产、增收、保护地力的最佳措施, 施肥最佳组合为N93 .8 kg/hm 2 、P2O575 kg/hm 2 、ZnSO437 .5 kg/hm 2 , 与对照相比可增产干草2 634 kg/hm 2 , 增加纯收益 2 63 .4元/hm2 。
Abstract:
The ex periment was conducted w ith an optimum reg ression design , study ing effect s of applying fertilizer on the yield and quality of herbage and economical benefit of herbage production . The results show ed that applying fertilizer w as an optimum method of increasing yield , income and pro tecting soil fertility of grassland .The optimum combination of applying fert ilizer on grass land was N 93 .8 kg/hm2 , P2O5 75 kg/hm2 , ZnSO4 37 .5 kg/hm2 .The dry g rass increased mo re than 2634 kg/ hm2 and the net income increased 263 .4 Yuan/hm2 , compared w ith control .
