| Abstract | To examine the effects of nitrogen and reclaimed municipal wastewater(RMW) irrigation on fruit quality of greenhouse tomato and soil nitrogen utilization, field experiments were carried out. Root-layer mineral nitrogen, total nitrogen, tomato yield, nitrogen in fruit, partial factor productivity from applied N, apparent N loss, nitrogen supplying capacity and fruit quality(flavor quality, nutritional quality) were analyzed. The results indicated that RMW irrigation leaded to an average of 1.72 40.39% increase in mineral nitrogen and total nitrogen of rhizosphere soil in 1, 2and 4cluster fruit expanding stage. Compared with CK, nitrogen in fruit, partial factor productivity from applied N and nitrogen supplying capacity of RMW irrigation were obvious increased. Furthermore, compared with CK, nutritional quality of tomato fruits were improved significantly. Maintaining soil fertility, the yield and nutritional quality of fruits were therefore notable improved under RMW irrigation, and which was an effectively management strategy of soil sustainable production and alleviating soil environment. |
