Title: Effects of Different Soil Moisture Treatments on Yield and Water Consumption of Tomato in Greenhouse in Northwest China
Abstract:Based on the growth and development rule of tomato,the lower limits of soil moisture in its seedling stage,flowering and fruit setting stage and fruiting bearing stage were respectively set as 50%,60%...Based on the growth and development rule of tomato,the lower limits of soil moisture in its seedling stage,flowering and fruit setting stage and fruiting bearing stage were respectively set as 50%,60% and 75% of the field maintaining water quantity,different irrigation water amount was controlled according to different soil irrigation maximum.The relationship between irrigation water and water consumption amount,yield and water use efficiency were studied.Results indicate that,the irrigation requirement and water consumption amount were significantly correlated with the upper and low irrigation limits that have interactive effect.Along with the increase of water stress degree,the modulus and intensity of water-consumption decreased when the low irrigation limit was the same,it is advantageous to gain high yield and water production efficiency when the upper and low irrigation limits(the percent comparing to the field water capacity)in seeding stage,flowering and fruit stage and fruit setting stage is 50%-65%,60%-75% and 75%-85%.Read More
