河套灌区粮食作物分层种植超吨粮田小气候生态效应研究

STUDY ON MICROCLIMATIC FACTORS AND CROP YIELD OF HIGH YIELD FIELD WITH INTERPLANTING IN THE ELBOW AREA OF YELLOW RIVER

本文采用一元二次回归分析方法，对黄河河套灌区超吨粮田不同层次的光温风分布状况进行了定量分析，求算了三因子在不同层次的最佳指标值Ｘ１及其相应的期望产量值Ｙ＿（ｍａｘ）。鉴于植株２／３处光温风分布综合反映了群体结构的生产潜力，故组建了２／３层次的多元非线性复合小气候效应模型。给出了亩产１２５０．０公斤的超吨粮理论指标。指出实现这一理论产量的关键，是广泛推广玉米催芽栽培技术。

The paper deals with wheat-corn intercroping field on whieh the yield can be morethan one ton per MU. The microclimatic conditions are anlyzed by way of statistical modelsdeduced from field tests,accordingly,the correlations between yields and the light,temperature and wind have been worked out.
