摘要
采用5因素二次回归正交旋转组合设计方法,研究了施肥量、种植密度、多效唑化控量、灌溉时间以及叶面喷硼量等因素对豫豆24产量的影响,建立了中等以上肥力栽培的产量决策模型,筛选出产量目标3 750 kg/hm2以上的高产优化栽培技术方案,经较大面积示范证明该优化栽培技术方案的增产效果十分显著。
Using two times orthogonal regression rotational fabricate design of five factors studied relationship on cultivation measures of influencing "Yudou 24" yield which are fertilizer amount, density, chemical manipulation amount, irrigation time and spraying leaf-surface with borax. Yield decision pattern over medium fertility was built. Cultivation scheme over 3 750 kg/ hm2 was formulated by computer imitating and exploring, and effect of increasing yield is very marked with optimal cultivation scheme by comparison experiments in great range.
