摘要
为促进黑龙江省大豆种植结构优化、发展大豆种植业,结合黑龙江省实际情况,综合考虑温度、降水、日照,建立气候适宜度模型。利用黑龙江省32个气象站点1998-2018年逐日气候数据及大豆全育期内的观测资料,计算大豆种植气候适宜度。基于计算结果及K-means算法将全省大豆种植区域进行划分。研究结果表明:黑龙江省大豆种植可以划分为4个区域,其中北部高寒地区的温度适宜度偏低(低于0.30),大豆种植宜选取耐寒性强、发育期短的大豆品种;中、南部地区各项气候适宜度均高于省内均值,气候条件基本满足大豆生长发育所需,适宜发展大豆种植业。最终基于区划结果及区域气候特征,对各区域大豆种植品种提出建议。
In order to promote the optimization of soybean planting structure and develop soybean planting, a climate suitability model considering temperature, precipitation and sunshine factors was established in combination with the actual situation in Heilongjiang province. This study calculated the climate suitability of soybean planting based on the daily climate data of 32 meteorological stations in Heilongjiang province from 1998 to 2018 and the observation data during the whole soybean breeding period. Then we divided the soybean planting areas of Heilongjiang province based on the calculation results and K-means. The results showed that the soybean planting regions in Heilongjiang province can be divided into four regions. In the northern region, soybean with strong cold tolerance should be selected adapt to the low temperature suitability. The climate suitability of the central and southern regions is higher than the average of Heilongjiang province. The climatic conditions of the two regions basically meet the needs of soybean growth and development. Finally we make recommendations of the regional soybean varieties based on the results of regionalization and regional climate characteristics.
