摘要: 研究表明,气象因子与小麦产量密切相关。在与小麦产量相关的35个气象因子中有12个因子的相关系数达到了显著水平;其中灌浆期降水与冬小麦产量呈极显著相关,且直接通径系数最高,对小麦产量形成的贡献率最大;其次是拔节期降水量和返青期降水量;5月份的蒸发量与冬小麦产量密切相关,达到极显著水平,其对小麦产量形成起较大的负向作用;小麦越冬期间的气温也是不可忽视的气象因素。据此,在制定小麦生产管理计划时,应将以上因素作为考虑的重点。

关键词: 冬小麦产量, 气象因素, 相关分析, 通径分析

Abstract: It was indicated that winter wheat yield was closely related to meteorological factors. Among the 35 meteorologicalfactors related to wheat yield, the correlative coefficients of 12 factors with yield were signif icant. The precipitationduring milking stage, which was significant correlated( at A0101 level) with winter wheat yield, had the highest pathcoefficient, and contributed the most to wheat yield establishment.The second and third factors were the precipitations injointing and stem elongating stage. Closely related to winter wheat yield, the evaporation inMay were significantly correlatedwith the yield at A0101level, showing significant negative effect on wheat yield establishment.Addit ionally, the soil temperaturein the winter was also a very important meteorological factor affecting winter wheat yield. Therefore, the above ment ioned factors should be emphasized when making wheat production and management plan.

Key words: Winter wheat yield, Meteorological factor, Correlation analysis, Path analysis
