摘要
[目的]研究气象环境条件对小麦品种灌浆进程和灌浆效率的影响。[方法]选择冬小麦半冬性和弱春性品种进行灌浆速度测定,同时选取相对应时间里平行观测的气象因素进行对比分析。[结果]结果表明,日照是影响灌浆速度的主导气象因子,温度是限制因子,其他气象因素的影响一般为间接作用。弱春性品种灌浆期间的气象指标低于半冬性品种,差别主要在于对温度的要求。生产中慎用大粒型的半冬性品种。良好的田间通风透光条件,有利于提高灌浆效率。[结论]协调好"源"、"流"、"库"的关系,可充分发挥气候条件的潜力,提高小麦籽粒重。
[ Objective ] The propose was to study the effect of weather condition on the winter wheat grouting rote. [ Method]Winter wheat varieties of haffwinter and feeble-spring were choice to determine grouting rate, while weather factors that were synchronously observed in relative time were analyzed. [Resuit]The results indicated that the dominant weather factor of effecting grouting rate was sunlight. Temperature was limiting factor. The effect of other weather factors on grouting rate was co,no,fly indirect, The weather indexes of feeble-spring variety during grouting were lower than half-winter,and the main differerlce was that they needed the different temperate. The big-grain ball winter variety was not popular in production. The favouuable draught and fully light condition in field was propitious to enhance grouting rate, [ Conclusion] The relationship among fountain, current and storeroom is finely harmanized, which can adequately exert the potentials of climate and raise seed grain weight of wheat.
