| 摘 要： | 本文是在省内不同气候、土壤肥力地区所做的区域性大豆自然生产力试验的基础上,采用二次正交旋转回归设计和双重组合设计方法,建立了黑龙江省大豆自然生产力模型,研究了影响自然生产力的环境因素——积温、降水和土壤有机质的变化及其交互作用对大豆产量的影响程度.同时,运用模型对区域性自然生产力和不同气候年进行了大豆产量的预测.

| Abstract: | This article made an analysis on the basis of the regional natural yield capacity of soybean experiments done in districts of different climate and different soil fertility in Heilongjiang Province in 1983-1985. Method of second orthogonal rotary regression design and method of double combination design were used, A model for natural yield capacity of soybean in Heilongjiang province is established. Environmental factors which effected the natural yield capacity-fluctua-tions temperature summation, precipitation and soil organic matter and their interactions were studied. A model was established and used to forecast the regional annual natural yield capacity and for different climatic years. |
