摘要
试验结果显示，滇中高产玉米每公顷能获１３５００ｋｇ以上的产量，主要是选用了优良杂交玉米品种，增加了种植密度，使叶面积指数由传统栽培的２．７提高到５．２，光能利用率由１．７２％提高到２．６６％。发挥了品种、密度、早播、壮苗等高产栽培技术的综合效应。
A set of comprehensive high-yielding culture technique of maize in middle Yunnan was proposed which was composed of high planting density(g×104 plants/hm2),hybrid variety Yedan No.6 insteaded of the local maise cultivae and transplanting early. As a result of this technique,the LAI of maize population raised to 5.2 from 2.7 of CK (the traditional culivated technique),the percentage of solar energy utilization increased to 2.66% from 1.72% of CK,the yield raised to 13500kg/hm2.
