摘　　要：通过田间试验,研究不同灌水量对日光温室辣椒土壤水分变化的影响。结果表明:随着灌水量的增加,0～60 cm土壤水消耗逐渐减少。各处理0～100 cm土壤贮水量随着灌水量的增加而增加,而土壤水分的消耗则随着灌水量的增加而明显减少。在苗期、营养生长期和结果前期,蒸腾蒸发量相对较少,灌溉水能基本满足植株生长需要,植株从土壤中吸收的水分较少。Soil moisture law of greenhouse pepper under different irrigation amount has been researched.The results showed that with the increase of irrigation amount,0～60 cm of soil water consumption decreased,0～100 cm treatments of soil water storage capacity along with the increasing of irrigation.While the consumption of soil moisture was reduced with the irrigation increasing,In the seedling stage,vegetative growth stage and fruiting stage,the evapolranspiration was relatively low,the amount of irrigation water could meet the basic needs of plant growth,and could obsorb ralively less water from soil.
