摘要：

宝清县原属黑龙江第三积温带区域，应用第三积温带水稻品种。随着气候变暖，黑龙江省宝清县县域活动积温增加，调整相适应的水稻种植结构，更合理的利用当地热量资源，是保障水稻高产稳产以及优质生产的重要措施。本文分析了宝清县近40年的有效积温、降水量和日照时数变化规律，并试验种植第二积温带应用品种。结果表明，宝清县可以应用第二积温带12片叶水稻品种，有利于优化水稻种植结构，促进水稻高产、优质发展。

Abstract:

Baoqing County was originally located in the third accumulated temperature zone of Heilongjiang Province, where rice varieties planted in the third accumulated temperature zone. With the climate warming, the accumulated temperature of activities in Baoqing County has increased. Adjusting the appropriate rice planting structure to make more rational use of heat resources is an important measure to ensure high and stable yield and high-quality rice production. In this paper the effective accumulated temperature, precipitation and sunshine hours in Baoqing County in recent 40 years were analyzed, and the varieties applied in the second accumulated temperature zone were tested and planted. The results showed that Baoqing County could apply 12 leaf rice varieties in the second accumulated temperature zone, which is beneficial to optimize the rice planting structure, and promote the development of high yield and quality of local rice.

Key words: rice, climate change, active accumulated temperature, Baoqing County
