Brackish Water Irrigation of Greenhouse Tomato in Non-cultivated Land
According to the experiments designed by single factor randomized block,the effects of different brackish water utilization modes on tomato growth,yield,quality and soil physicochemical property properties were studied with the brackish water irrigation as the control.The results showed that compared to brackish water irrigation,the yield under purified water irrigation was improved by 44.78%,soil electrical conductivity in 0~~20 cm and in 20~40 cm decreased 67.21 % and 10.61% respectively,and Vc,total sugar,titratable acid,dissolvable solid content all had an extremely significant differences; Water use efficiency increased and fruit quality was affected under purified water irrigation.Under mixed irrigation,the yield increased by 26.56 %,the nutrient content of fruit was higher than that under purified water irrigation but it was less than that uner brackish water irrigation,the salt in concentrated root layer was not obviously accumulated,and the production cost reduced by 50 %.The mixed irrigation could be treated as the best utilization pattern after brackish water being purified and brackish water irrigation was suitable for high-quality tomato production.
