冬玉米高产栽培途径研究

Studies on The High yield Cultivation Techniquesof Winter Corn

１９９６～１９９７年对云南省南部热区冬玉米高产栽培的机理和配套措施进行了研究。结果表明，高产田的产量及其构成因素、各叶叶面积、光合势都显著地超过普通田。建立了密度与产量、施肥量与产量的非线性回归方程。高产田的纯收入也较普通田的高。

A research on the high yielding principles and relevant cultivating techniques for winter corn was conducted in tropical area in south Yunnan Province from 1996 to 1997 The results showed that yield,yield components,leaf area of each leaf,and leaf area duration in the high yielding fields were significantly higher than those in the general fields Non linear regression equations on cultivating densities to yield and the amount of fertilizer applied to yield were established The benefit from the high yielding fields was higher than those from the general fields Bazed on the experimental data,a package of the high yielding cultivation techniques for winter corn was provided
