甘肃省油菜生态气候适应性分析与适生种植区划

Analysis of Ecological Climate Adaptability and PlantingDivision of Oilseed Rape in Gansu Province

采用数理统计方法分析了甘肃省甘蓝型春油菜及白菜型冬、春油菜的生理特性和要求的生态气候条件,确定了生态气候适生种植区划综合指标体系,将甘肃省油菜种植区划分为五级,并针对各地资源特点和油菜生育特性提出了提高生态气候资源利用效率的途径。

The physiological characters and required ecological climate conditions of oilseed rapes, including spring oilseed rape (Brassica napus L.), spring and winter oilseed rape (Brassica campestris L.), in Gansu Province were statistically analyzed. The indices for the suitable planting division of oilseed rape were determined. The oilseed rape planting in Gansu Province was divided into five zones. According to the characters of the ecological climatic resources and the growth of oilseed rape in the different planting zones, the measures to enhance the utilizing efficiency of the ecological climatic resources for oilseed rape production in Gansu Province were put forward.
