CIMMYT玉米种质AC8328BNC_1的耐瘠性研究

The Study of Barren Endurance of Population of Corn AC8328BNC1 from CIMMYT

采用不完全随机区组设计,通过玉米品种和施肥水平两因素试验,对玉米生物学和经济学性状作变异度分析,对小区产量作方差分析和对单位产量作差数百分率分析,以系统鉴定CIMMYT玉米种质AC8328BNC1的耐瘠性。结果表明:①AC8328BNC1具有较强的耐低氮和低磷能力,有良好的丰产性和广泛的适应性,是一个优良的国外玉米种质资源,应加大研究和利用力度;②在低肥力土壤上,更应重视玉米科学合理施肥的重要性和追第二次肥的必要性。

Barren endurance of population of corn AC8328BNC1 form CIMMYT were appraised by two factors test of variety of corn and level of fertilization. The results showed: ①AC8328BNC1 had a stronger endurance of low-N and low-P, and had a good high yield and wide adaptation, and was a good abroad resources of population of corn; ②On the lower fertility of soil, it is very important and essential for corn to fertilize scientifically and reasonablly and apply the second fertilizer.
