摘　　要：通过田间小区试验和数理分析方法研究了温室内在小管出流条件下茄子的耗水规律。研究中采用土壤体积含水率作为灌水控制指标,同时监测了茄子的长势、果实品质和产量等。初步结果表明:茄子的耗水规律为苗期平均日耗水强度0.9 mm/d;开花着果期1.1 mm/d;结果期为2.8 mm/d,全生育期耗水量约为149 mm。Based on field experiment and mathematical statistics,the water consumption of eggplant in the greenhouse under small tube flow is studied in this paper.During the research,soil moisture is taken as the index for irrigation control,meantime eggplant growth performance,yield and fruit quality are monitored.The results show that the water consumption of greenhouse eggplant is about 149mm during the whole growing.The daily water consumption intensity in the period of flowering and fruiting are 0.9mm per day,1.1mm per day and 2.8mm per day,respectively.
