- Title:
- A Study on the Mathematical Model of Winter Wheat With Comprehensive Cultural Practice in North Mountainous of Qian County Rainfed Highland
- 摘要:
- 采用五元二次正交旋转回归设计，对影响旱地小麦产量最主要的播期、播量、施氮、施磷、施油饼量五项农艺措施进行田间试验。通过微机统计分析，明确了各项农艺措施的主次作用，建立起综合农艺措施优化数学模型，筛选出该地区不同产量水平及亩产432kg的最佳农艺措施组合方案，为黄土台塬阶地区旱地小麦高产优质规范化栽培提供了科学依据。
- Abstract:
- The effects of five agronomic measures including sowing time, sowing norm, N, P fertilizer and oil cake norm application on winter wheat of dry land by orthogonal rotational regessive designed field experiments been carried out and a set of mathematical model of comprehensive cultural practice were put forward by statistical analysis with computer.From results of the experiments the optimizational scheme of agronomic measures combination in the different yield levels were selected and scientific basis for high-yield, top-quality and slandrdization cultivate to winter wheat were provided in the loessal tableland area.
