摘要
通过对全球及黑龙江省气候趋势的分析,说明黑龙江省气候至少在未来的几十年内仍处于持续增温的时期。气温升高对黑龙江省水稻生产是有利的,使水稻的北界继续向北扩展,水稻适宜区扩大,同时,原水稻种植区积温增加,可以种植更晚熟品种,单产提高。积温增加、CO2浓度提高和育苗条件的改善,实际生产可用品种熟期可比原积温划分区的可用品种晚1~2个熟级。
Through the analysis of climate trends of global and Heilongjiang Province,the results showed that the climate were still Continued warming,at least in the coming decades in Heilongjiang Province.Elevated temperature is favorable for rice production to the northern boundary of rice continued northward expansion of rice suitable area to expand at the same time,accumulated temperature of original planting area will increase,and will grown even more late-maturing varieties,increase the yield of rice.Increased accumulated temperature,increased CO2 concentration and improved breeding conditions can be comparable to the original maturity varieties accumulated temperature zone can be divided into 1~2 late varieties mature level.
