【摘要】 采用二次饱和D-最优设计方案,对洛麦22产量影响较大的播种期(x1)和播种量(x2)二因素高产优化栽培模式进行了研究。结果表明:播种期、播种量的合理配置是夺取高产的关键,并得出洛麦22的优化栽培技术组合,即最佳播种期为10月6~7日,最佳播种量为114.8 kg/hm2。更多还原

【Abstract】 Through the quadratic saturated D-optimal design,the optimum cultivation technology of wheat new variety "Luomai 22" was studied.The results indicated that the rational coordination of sowing date and sowing quantity was the key to obtain high yield,the optimum sowing date of "Luomai 22" was October 6~7th,and the best sowing quantity was 114.8 kg/hm2.更多还原
