【摘要】 研究了河西绿洲灌区调亏灌溉条件下春小麦穗长、有效小穗数、穗粒数、穗粒重、单粒重及株高等产量构成要素的变化,并对小麦籽粒产量、生物产量、收获指数与产量构成要素及株高间和产量构成要素之间的相关关系进行了分析研究,以期为该区春小麦进行适度水分调亏提供科学依据。更多还原

【Abstract】 The yield components such as spike length,fertile spikelets,spike kernels,grain weight,kernel weight and plant height of spring wheat were studied under regulated deficit irrigation in the Hexi oasis irrigation region.In addition,the correlations between the grain yield,above-ground biomass,harvest index and yield components,plant height,as well as those among yield components were also analyzed,aimed to provide some scientific reference for proper water deficit irrigation in this region.更多还原
