调亏灌溉对日光温室青茄品质和耗水规律的影响
Effects of Regulated Deficit Irrigation on Quality and Water Consumption of Solar Greenhouse Green Eggplant
摘要
Abstract
Effects of different soil moisture at different growth stages on water consuming law,yield,water use efficiency,and appearance quality of green eggplant planted in plot experiments under drip irrigation in greenhouse were studied to determine the irrigation index and irrigation scheduling of water saving,high yield,superior quality and high efficiency of green eggplant.The results showed that the water consumption peak of green eggplant occurred at the mature stage,and the water consumed coefficient was from 49.96% to 64.11%;the amount of water consumption at seedling stage was minimum with 8.64%~16.68% of the water consumed coefficient.Properly regulated deficit irrigation with 80% of full water supply at seedling stage and at the mature stage could improve the yield and water use efficiency,and excessively water deficit with 60% of full water supply at the blooming stage improved the appearance quality of green eggplant,but significantly reduced the yield and water use efficiency.Taking the yield and quality into consideration,the proper irrigation scheduling under drip irrigation in greenhouse was that the irrigation cycle was 10 d,properly regulated deficit irrigation time was at seedling stage and the mature stage with the irrigation quota of 12 mm and 20 mm respectively,and the irrigation quota of sufficient irrigation at the blooming stage was 25 mm.关键词
