本文论及的数学模型研究,实质上是为解决河西地区春小麦“均衡高产”技术服务的。此研究与数理统计上的数学模型研究在设计、分析、综合技术上是一致的,但在应用上只是对有生物学意义的高产段的优化农艺措施有实用价值,超出此一范围的农艺措施预报(尽管在试验约束范围内)不能保证其可靠性。但这已经能基本满足生产要求,更由于通过这种约束,可以把表面上的主效措施研究转化成实质上的包括产量形成中品种、环境、措施在内的综合研究,反而增加了实用价值。
The mathematical model discussed in this article is essentially to solve the problem of “balanced and high yield” spring wheat in Hexi region. This research and mathematical statistics mathematical model research is consistent in design, analysis and comprehensive technology, but it has practical value only in the application of optimized agronomic measures with high biological yield and high yield. Agronomic measures beyond this range Forecasts (although within test constraints) can not guarantee their reliability. However, this can basically meet the production requirements. Moreover, by this kind of constraint, the study of the major efficiency measures on the surface can be transformed into the substantial comprehensive research including the variety, environment and measures in the process of yield formation, which in turn increases the practical value .
