| 摘 要： | 田间试验采用3种滴灌湿润比(20%、40%、60%),并以传统漫灌(土壤湿润比为100%)为对照,利用负压计和石膏块监测果树根区土壤水势,观测不同生育阶段内果树的生长指标;用水量平衡法计算不同处理梨树不同生育期的日均耗水量、作物系数与蒸发皿系数.试验结果表明,充分灌溉条件下,滴灌湿润比为20%、40%、60%的成龄香梨...

| Abstract: | The wetted soil percentages included 3 levels(20%,40% and 60%) and the traditional flood irrigation(100% of wetted percentage) was used as control.Soil water potential in the root zone was monitored by a tensionmeter and gypsum blocks.The growth indices of fruit trees were recorded at different growth stages.The daily water use,crop coefficients and pan coefficients under different drip irrigation treatments were estimated by water balance method.The results indicated that the tree water uses under wetted p... |
