摘　　要：为了给黑龙江省板蓝根种植提供科学依据,基于1991—2020年黑龙江省84个观测站逐日地温和降水资料,采用5 d滑动平均法、3 d滑动平均法、克里金插值法、数理统计分析法以及层次分析法,探讨了板蓝根播种期气象条件适宜性和不同温度条件下播种对板蓝根产量及有效成分含量的影响,建立了板蓝根播种期气象条件适宜度评价模型。结果表明:日平均5 cm地温稳定通过12℃为最佳播种期。黑龙江省5 cm地温稳定通过12℃初日分布为5月1—30日,其空间分布呈现由南向北、由平原向山地日期逐渐推迟的趋势。总体趋势是杜蒙、泰来、甘南、肇源和五常等区域初日出现较早,漠河、呼中、新林、塔河、乌伊岭、嘉荫和绥芬河等区域初日出现较晚。In order to provide a scientific basis for the planting of Isatis tinctoria in Heilongjiang province,based on the daily soil temperature and precipitation data from 84 observations in Heilongjiang province from 1991 to 2020,using the 5-day sliding average method,3-day sliding average method,Krikin interpolation method,mathematical-statistical analysis method,and hierarchical analysis method,the suitability of meteorological conditions at sowing stage of Isatis tinctoria and the effects of sowing at different temperature conditions on yield and active ingredient content of Isatis tinctoria were discussed.The results showed that the optimum sowing time was 12℃with a daily average temperature of 5 cm.The first day of the 5 cm below-ground temperature stable passing 12℃in Heilongjiang province is from May 1 to 30,and its spatial distribution shows a trend of a gradual delay from south to north and from plain to mountain.The general trend is that the first day appeared earlier in Dumeng,Tailai,Gannan,Zhaoyuan,and Wuchang,while the first day appeared later in Mohe,Huzhong,Xinlin,Tahe,Wuyiling,Jiayin,and Suifenhe.
