超高产条件下农艺措施与小麦产量关系的研究

为了探讨超高产小麦定量化、规范化、模式化栽培技术方案，采用五元二次回归旋转组合设计，研究了超高产小麦的播期、播种量、施氮量、施磷量及施有机肥量等5项农艺措施与产量的关系及其交互作用。结果表明，5项农艺措施与产量之间存在着明显的函数关系，建立了产量目标数学模型。5项农艺措施对产量影响的大小不同，播期与播种量、播种期与有机肥、播种量与施N量、施N量与施P2O5量、有机肥与施P2O5量之间的相互效应达到极显著水平，生产中注意协调5项农艺措施之间的关系。‘豫麦49-198’产量达到(9393±234.8) kg/hm2的优化农艺措施是：播种期10月11-13日，播种量91.9~99.4 kg/hm2，施N量213.5~231.4 kg/hm2，施P2O5量144.7~157.2 kg/hm2，有机肥施用量41117.0~41367.0 kg/hm2。经在同样生态类型区麦田示范推广应用，效果非常显著。

Research on the Relationship Between the Agronomic Measures and the Wheat Yield under the Super High-yield Condition

To explore the super high-yield wheat quantitative and standardized cultivation technique,we optimized the program with the design of five quadratic regression rotation,and studied the relationship and the interactions between the ultra-high-yield wheat＇s yield and the five agronomic measures,such as sowing time,the sowing rate,the nitrogen rate,the phosphorus rate and the organic fertilizer rate.The results showed that：there was a clear functional relationship between the five agronomic measures and the yield,and finally the mathematical model of the production goals was established.The effects of five agronomic measures on the yield were different,the interactions between the sowing time and the sowing rate,the sowing time and the organic fertilizer,the sowing rate and the nitrogen rate,the nitrogen rate and the P2O5 rate,and the organic fertilizer and the P2O5 rate reached the significant level,and the relationship among five agronomic measures was coordinated effectively.The yield of＇Yumai 49-198＇reached（9393±234.8） kg/hm2 and its optimized agronomic measures were as follow：the sowing time was from October 11 to 13,the sowing rate was 91.999.4 kg/hm2,the nitrogen rate was 213.50-231.4 kg/hm2,the P2O5 rate was 144.7-157.2 kg/hm2,and the organic fertilizer rate was 41117.0-41367.0 kg/hm2.After applying on the similar ecological demonstration area,we found the effect was very significant.
