【摘要】 采用小区试验方式,在施肥水平、管理条件一致的情况下,研究了不同种植密度对青贮饲用玉米Zeamays产量和品质的影响。结果表明:不同的栽培密度对青贮饲用玉米产量和品质都有影响,采用85 cm×15 cm和65 cm×25 cm播种密度(即61 530~78 450株/hm2)的青贮玉米产量高,品质较好,效益最高,差异达到极显著水平,为四川省青贮饲用玉米的大田生产提供了重要的依据。更多还原

【Abstract】 With plot test design,the effect of different planting densities on the production and quality of silage maize under the same fertilizer level and management was studied.The result showed that different planting densities affected the production and quality of silage maize,seeding densities 85 cm×15 cm and 65 cm×25 cm(namely 61 530~78 450 plant/hm~2) had higher yield 、better quality and the highest benefit.There were a positive correlation.Results of this experiment provided a base for field planting of silage maize in Sichuan province.更多还原
