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。根据上述结果提出了一套冬玉米高产栽培的综合配套技术 From 1996 to 1997, the mechanism of high-yield cultivation of winter maize in south hot area of ​​Yunnan Province and its supporting measures were studied. The results showed that the yield and its components of high-yielding fields, leaf area and photosynthetic potential of all high-yielding fields significantly exceeded that of common field. A nonlinear regression equation of density, yield, fertilizer amount and yield was established. The net income of high-yield fields is also higher than that of ordinary fields. Based on the above results, a set of comprehensive supporting technologies for high-yield cultivation of winter maize was put forward
