【 摘 要 】

The effects of formulated fertilization on the soil physical and chemical characteristics of early ripe peach orchard were studied in Shanquan Town, Longquanyi District, Chengdu City, Sichuan Province of China. Base fertilizer of organic fertilizer is 600 kg/667m2, urea is 12-20 kg/667m2, monoamine phosphate is 24 kg/667m2, superphosphate is 80 kg/667m2, potassium sulfate is 56 kg/667m2; germination fertilizer application borax is 6 kg/667m2, urea is 10 kg/667m2; hard-core fertilizer compound fertilizer 40 kg/667m2, potassium sulfate 20 kg/667m2 increased the soil organic matter content by 64.04%-98.95%, soil total phosphorus and available phosphorus by 22.43%-29.52%, 52.38%-75.16%, total potassium and available potassium by 21.71%-31.11%, 19.4%-39.59%, exchangeable calcium by 31.76%-35.36%, and exchangeable magnesium by 2.24%5.88%, respectively, compared with the control. By formulated fertilization, fertilizer application decreased by 23.53%- 28.24%.
