通过分析永宁、固原两地的气象资料和春小麦生长发育资料 ,发现宁夏春小麦生育期间气候变暖 ,使得春小麦春化阶段缩短、单株成穗率下降、穗粒数减少、千粒重降低。据此 ,提出了扩大冬小麦种植面积、适当提前播种期、控制群体结构等对策措施
By analyzing the meteorological data of Yongning and Guyuan and the data of spring wheat growth and development, it was found that the climate warming during the growth of spring wheat in Ningxia could shorten the vernalization stage of spring wheat, reduce the rate of per plant panicles, reduce the number of grains per panicle, and reduce the grain weight of 1000. Based on this, some countermeasures such as expanding winter wheat acreage, proper sowing date and controlling population structure
