膜下滴灌调亏对加工番茄产量和水分利用效率的影响
Effect of Regulated Deficit Drip Irrigation on Economic Yield and Water Use Efficiency of Processing Tomato Mulched with Plastic Film
摘要
Abstract
Effect of deficit water regulation on soil moisture,plant height,dry matter accumulation,economic yield,water use efficiency,and irrigation water use efficiency was studied through experiment of regulated deficit drip irrigation in different growth period of processing tomato mulched with plastic film.The result showed that regulated deficit drip irrigation with 55% of water content in field capacity during seedling could not only decrease total irrigation water,water consumption,and soil moisture before and after transplantation,but also significantly(p0.05) increase fruit number per plant,fruit weight per plant,economic yield,irrigation water use irrigation,and water use efficiency of processing tomato,while the result was significantly(p0.05) different to that mentioned above for the water deficit regulation in flowering and fruiting,especially in the former.The economic yield was significantly(p0.05) increased while the water use efficiency and irrigation water use efficiency were significantly(p0.05) decreased without water deficit regulation and that merely regulating water deficit at harvesting.关键词
