摘要
大白菜喜温和气候,它主要的生长时期,平均温度大都以16±10℃的条件为宜.采用Cob-Douglas生产函数模型和通径分析方法,探讨气象要素对大白菜产量综合效应的结果表明,大白菜在我地栽培,其生长过程中对气象要素的需求量,与它的生物学特点相吻合.
The Chinese cabbage prefers to grow in a temperate climate. The most suitable average temperature for it is 16±10°C at its main growing period. In this paper, we adopted Cob-Douglas production function model and path analysis in exporing the synthetic effect of climatic conditions on the yield of the Chinese cabbage. The result shows that the climatic conditions in Hengyang is identical with the biological characteristics of the cabbage in the course of its growth.
