玉米高产群体结构问题,是玉米栽培重大理论课题。但至今始终没有从理论上得到彻底解决,因此这一课题成为国内外跨世纪老课题。笔者通过密植研究玉米高产群体结构,最终从理论上破解了玉米高产群体结构这一课题。这个玉米高产结构,是以一个公式形式体现出来的。即:最高单产=品种标准单株产量/(最小·常数)×适宜密度/(最大·变数)公式的发现解决了两个理论问题。第一、玉米个体、群体在什么情况下最协调,单产最高,第二、找到了玉米增产正确途径。
Maize high-yield population structure problems, is a major theoretical issue of corn cultivation. However, it has not been completely solved theoretically so that this subject has become a cross-century old topic at home and abroad. The author studied the structure of high-yielding maize population through close planting, and finally solved the problem of high-yield population structure of maize theoretically. The high-yield structure of corn is embodied in the form of a formula. Namely: The highest yield = standard varieties per plant yield / (minimum constant) × appropriate density / (maximum, variable) The discovery of the formula solves two theoretical problems. First, the individual corn, the group under the most coordinated circumstances, the highest yield, second, to find the correct way to increase corn yield.
