土壤水分状况对温室滴灌番茄水分利用效率及果实品质的影响
Response of Tomato Yield, Quality, and Water Use Efficiency to Soil Water Status under Drip Irrigation in Greenhouse
摘要
Abstract
A drip irrigation experiment was conducted in greenhouse to study the effect of different soil wa ter status at various stages on tomato yield, water use efficiency (WUE) and fruit quality. The result showed that tomato yield had a response of threshold value to soil moisture, and as long as the lower limit of soil moisture was not less than 60％, tomato yield decreased unobviously and WUE increased. Further more, there was a close relationship between soluble solid content (SSC), vitamin c (Vc) and soil water moisture, and the content of SSC and Vc decreased with the increasing of soil water content. Water deficit at fruit set stage and at maturity stage could increase the content of SSC and Vc, and the more water stress, the higher its content, especially its content raised more obvious at maturity stage. Considering to mato yield, WUE and fruit nutritional quality (SSC and Vc content), soil water content maintained at 60％～70％ during fruit set stage and maturity stage could save water and increase yield and fruit quality.关键词
