Abstract:
The effects of optimization of fertilization，application of coated fertilizers，traditional fertilization method on N，P accumulation in different soil layers and the yield of tomato were studied.The results showed that NO3--N content in 0~120 cm soil layers of traditional fertilization were significantly higher.N top dressing amount were reduced by 1/3,1/2 respectively in coated fertilizer treatment(SCZ) and optimize treatment(YH)，NO3--N content in surface layer (0~30 cm) of SCZ treatment was significantly higher than that of YH，there was no significant difference in 30~90 cm soil layer，but in 90~120 cm soil layer it was significant reduction.The amount of application of P fertilizer in FHF and SCZ treatments was the highest，so their residues in the soil were the highest.Compared with YH treatment，they significantly increased the P content in surface soil，but no significant difference in 30~120 cm soil layers.The nitrate content in traditional treatment tomato was the highest，10.9%~17.7% higher than that of others，35.1% higher than CK.Fertilization treatments significantly improved the yield of tomato，the yield of SCZ,YH treatments decreased by 0.8%，15.8% than traditional treatment，but the difference was not significant.
