摘要: 采用二次回归正交旋转设计试验方法,研究了四种不同生态区玉米高产栽培的综合农艺措施。结果表明(1)密度、氮素和磷素三因素及其交互作用对产量均有一定影响,但不同生态区域、不同品种各因素作用顺序及方式不一致;(2)不同生态区各品种采取一定的农艺措麓组合,均可获得较高耔粒产量;(3)本文得出的玉米高产栽培综合农艺措施取值范围为,每亩密度2813-4185,亩需有效氮6.9-13.5公斤,有效磷2.7-9.0公斤。

Abstract: The agronomic practices for the high yield of maize in different EcotopeofSichuan were siudied by using the orthogonal rotation design of quadraticregression. The results showed, (1). that Density、Nitrogen and phosphorus and its interaction affected the yield to a certain extont, but the sequcuce and wqys of cffect were not the same in defferent ecotoppe for different varieties, (2) that the high yield of grain could be gained for each of the varietres in different ecoiope with certain agronomic practices, (3). that the value rang of the agronomic practices for the hihg yiedl of maize were density of 2814-4185, 6.9-13.5 KG N available and Z. 7-9.0 KO N P2O5 available per mu.
