【摘要】 抽梢开花期及果实膨大期是柑桔需水的主要时期。土壤适宜含水率(粘壤土)应为20～25%。低于20%为灌水的土壤水分指标;叶片水势在-7×10~5Pa、水分饱和亏达6%,可作为灌水的植株生理指标。更多还原

【Abstract】 Flush--flowering period and fruit size expanding period are critical forthe growth of citrus trees in term of their water requirement,duringwhich soil moisture in the root-zone should be maintained at 20-25%.Soil moisture lower than 20%,or leaf water potential of-7×10~5 Pa,or watersaturation deficit of about 6% may be taken as indexes for irrigation.更多还原
