黑龙江省草地农业积温带划分初探

Primary Study on the Grassland Agriculture Accumulated Temperate Zone Partition in Heilongjiang Province

根据黑龙江省146个地面气象站2013年的日气象的观测资料,开展了草地农业积温带的划分研究。结果表明黑龙江省≥0℃的年积温为2 115.93℃～3 617.20℃,并将草地农业积温带划分为5、6个积温带,可以更好地为黑龙江省农业种植带的变化、作物适宜种植区变化以及品种更替等提供帮助,并为今后该地区草地积温带的划分提供技术支撑。

Based on the observational data of 146 meteorological stations in Heilongjiang in 2013,the grassland agriculture accumulated temperate zone partition was researched. The results showed that the range of ≥0℃ annual accumulated temperature of Heilongjiang province was 2 115.93 ℃-3 617.20℃,and the grassland temperate zone was divided into 5 and 6 accumulated temperate zones.It could provide the technical support for the division of the agricultural planting belt in Heilongjiang province,the suitable planting area change and the variety change. It could also provide the technical support for the division of the grassland temperate zone in the future.
