Abstract
To improve fertilizer use efficiency,fertilizer applicator fertilization was used as a simple fertilization method on fruit trees. This study was carried out to explore the influence of the ditch broadcast fertilization in the radial shape and fertilizer applicator on the changes of soil nutrient dynamic content,and the impact on the nutrient content of leaves,peach yields and qualities of 10-year-old late-maturing peach cultivar Chinese peach. The results showed that with the same amount of fertilizer,the soil content of potassium and available phosphorus under the treatment of 0 to 40 cm soil fertilization with the fertilizer applicator,was significantly higher than the ditch broadcast fertilization in the radial shape,the maximum increase was 46. 92% and 30. 0%,respectively,and no significant differences appeared compared to 40 ~ 60 cm soil; Each soil layer NH+4- N,NO-3- N content with fertilizer applicator fertilization was significantly higher than the ditch broadcast fertilization in the radial shape,and the maximum increase was 76. 44% and 48. 77%,respectively. Total contents of nitrogen and phosphorus in leaves increased with increasing amount of fertilizer. The difference between the same fertilized amounts was not observed significantly. With the same amount of fertilizer,fertilizer applicator had a positive effect on single fruit weight,fruit diameter,contents of soluble solids and fruit yield.So this study can provide a theoretical basis for fertilizer applicator fertilization increasing soil nutrient content and orchard efficient fertilization.
