Abstract: This study aims to test the effects of phosphorus fertilizer reduction on tomato cultivation. A field experiment was conducted to evaluate the effects of phosphorus fertilizer reduction on tomato plant growth, yield, quality and soil nutrient. There were three treatments, respectively, conventional phosphorus fertilization (CK), 50% reduction of phosphorus fertilizer (P-1) and 70% reduction of phosphorus fertilizer. Reduction of phosphorus fertilizer had little effect on plant height, stem diameter, leaf number and plant height/stem diameter ratio and yield of tomato. The single fruit weight, yield per plant and yield per unit area of tomato was 173-181 g, 1.81-2.05 kg and 51.9-56.9 t/hm2 in all treatments. Compared with CK, P-2 treatment increased the number of root ＞ 2 mm and the root cap ratio by 72.6% and 28.0% , respectively. Both phosphorus reduction treatments significantly improved tomato reducing sugar content and sugar acid ratio as compared with that of CK. The tomato sugar acid ratio in P- 2 treatment was significantly higher than that in P- 1 treatment. The phosphorus reduction treatments both significantly reduced topsoil available phosphorus as compared with that in CK. Reduction of phosphorus fertilizer did not affect tomato yield, while increased tomato quality and improved soil environment.
