摘要
对滴灌条件下,不同供水方式对温室桃树耗水量、产量及水分利用效率的影响进行了系统研究,结果表明,随着灌水次数和灌水量的增加,滴灌温室桃树各物候期阶段耗水量呈增加趋势;在整个年生长周期中,各处理土壤水分消耗的变化均呈双峰曲线,需水高峰期分别出现在花芽分化期和果实发育期;在各灌水处理中,T4处理产量和水分利用效率最高,分别达41 521.5 kg/hm2和54.46 kg/(mm.hm2);日光温室桃树耗水量与产量、水分利用效率间均呈二次曲线关系,经相关性分析,相关系数分别为0.894 9,0.915 3,达0.01极显著相关水平。
The water consumption, yield and WUE for the peach in greenhouse under the drip irrigation conditions were studied. The results showed that the water consumption for the peach at different stages increased with irrigation frequency and quantity increasing. During the whole growing stages per year, the water consumption has similar tendency under the different irrigation modes and the relation curves had two peaks at flower bud developing stage and fruit development stage respectively. Among different irrigation treatments, the highest yield and WUE of T4 could arrived 41 521.5 kg/ha and 54.46 kg/（mm· ha）. The relationship of the yield , WUE and water consumption for the peach appeared to be the parabolic curve which correlation coefficient could arrive 0.894 9 and 0.915 3 respectively.
