摘要: 根据分期播种试验资料,利用最小二乘法得到黑龙江省主栽大豆品种各生育期所需有效积温和生育期下限温度等热量指标;利用1981-2002年全省81站逐日气象资料对热量资源在50km×50km网格上的内插得到的热量资源空间分布、可能生育期日数结果,与各主栽品种全生育期活动积温、生育期日数的实测值作对比,分析讨论了大豆不同熟型品种分区指标和各主栽品种的适宜分布区域。最后将黑龙江省大豆产区划分为两个优势产区(松嫩平原产区和三江平原产区)和一个次要产区(黑河、伊春等北部产区)。

Abstract: Based on the phonological data, the thermal indexes, such as the active accumulated temperature and minimum limit temperature in each growing period of soybean, were calculated for the main cultivated soybean varieties in the Heilongjiang Province, by using the Least Squares Method. The spatial distribution of thermal resource and the possible days of growing period were obtained by interpolating in the 50km50km grid based on the daily climate data in 81 stations from 1981 to 2002 in the Heilongjiang Province, and compared with the observed the active accumulated temperature and days of growing period for the main cultivated soybean varieties. The indexes for dividing zone of different mature period patterns of soybean varieties and suitable planting zones for the main cultivated soybean varieties were discussed. The soybean production zone in the Heilongjiang Province was divided into two dominant production zones (Songnen and Sanjiang plain) and one subsidiary production zone (Heihe and Yichun regions).
