摘要：

青贮玉米有整株青贮和粮饲兼用两种主要利用方式，一些通过审定的青贮玉米品种具有生物产量和子粒产量均较高的特点，而实现经济效益最优最终决定青贮玉米的推广和应用价值。以京科青贮516和农大108两个玉米品种在不同密度条件下的乳熟期整株产量、完熟期子粒产量以及经济效益差异为研究对象，进行了有关的分析与研究，综合比较，整株青贮经济效益要高于收获子粒，京科青贮516在60000株/hm2密度乳熟期生物产量、成熟期子粒产量均最高，不同收获期的所有组合中经济效益居第1位和第2位，乳熟期效益为7113.9元/hm2，完熟期效益为6947.7元/hm2，对乳熟期和完熟期的经济效益值进行成对数据t测验，t=1.775，t0.05=2.571，t

Abstract:

Maize silage can be utilized in the form of whole ensiling and cereal＆silage maize using, many breeds of maize silage have high biomass yields and grain yields, optimum of benefit will determine the value of extension and utilization. Researched and analyzed the differences of biomass yields of milky maturity ,grain yields of full maturity and economic benefit of maize silage Jingke 516 and Nongda 108 under different density, compared in synthesis, the economic benefit of whole ensiling are higher than the grain yields, the yields of silage maize Jingke516 in milky biomass and full maturity both were highest under density of 60000 palnts/hm2, in all the treats, the economic benefit was 7113.9Yuan/hm2 in milky maturity and 6947.7Yuan/hm2, the results of t test between milky maturity and full maturity were t=1.775，t0.05=2.571，t
