摘 要:通过对日光温室桃树滴灌条件下需水规律的研究,结果表明:在滴灌条件下,日光温室桃树的需水量与产量呈二次曲线关系;日光温室桃树温室生长阶段和露地生长阶段具有相似的需水规律,均表现为前期小,中期大,后期小, 露地生长阶段需水强度大于温室生长阶段;在露地生长阶段需水高峰期出现在花芽分化期,而在温室生长阶段的需水高峰期出现在果实发育期。The paper studied the water consumption laws of the peach planted under the greenhouse and drip irrigation condition. The results showed the relationship between peach water consumption and yield appeared to be the parabolic curve. The peach has the similar water consumption laws at growing stages both in greenhouse and without plastic-mulched, which appeared lower at prophase stage and anaphase stage, higher metaphase stage. The amount of water consumption at stage of without plastic-mulched is bigger than that at the greenhouse. The peak water consumption at stage of without plastic-mulched lie in flower initiation stage, but that at the greenhouse stage lies in the development of the fruits.
