摘要
试验采用5因素5水平2次旋转回归正交组合设计,测得参数后,建立起烟农15号小麦产量与籽粒蛋白质含量的农艺措施回归模型。又通过微机模拟仿真,证实在产量与蛋白质含量之间存有矛盾;同时看到在一定范围内产量与蛋白质含量同步增长的趋势,进而揭示出亩产400～475kg是该品种的高产优质同步区间。并指出在该区间内,运用合理的农艺措施,能使其籽粒蛋白质含量提高到15％以上。经2年示范验证,收到了良好的效果。
According to the parameters obtained through the orthogonal combination design of quadyatic regression with 'five factors' and 'five levels',the regression model of agronomical measures for yield and grain protein content of the wintery wheat variety,Yannong 15, was set up. By computer simulation,it was proved that the contradiction between yield and protein content was present,And in a definite range the trend of synchronous increase of yield and protein content was seen.It was concluded that the synchronous range of high yield and protein content was from 400 kg per mu to 475 kg per mu.And it was pointed that in this range the grain protein content could be increased by more than 15%.Good results were got for two years through exemplary tests.
