Abstract:

To lay a theoretical basis for peach soil testing and nitrogen fertilizer recommendation in China, the method of “scattered experimental data integration” and the method of “nutrient balance and target yield minus soil fertility yield” were employed to study the rich-lack index (RLI) of soil alkaline hydrolysis nitrogen and organic matter and the recommended soil fertilizer application rates (RSFAR) for peach planting in China. The results showed that the RLI of soil alkaline hydrolysis nitrogen for peach planting in China from the first to the sixth level was ≥206, 125-206, 76-125, 46-76, 28-46 and <28 mg/kg, respectively; the RLI of soil organic matter from the first to the fourth level was≥53, 32-53, 12-32 and <12 g/kg, respectively. When the N fertilizer use efficiency was 40% and the target yield was 15-60 t/hm2, the range of the RSFAR of N for the first to the sixth level soil was 0-0, 20-80, 40-159, 60-239, 80-318 and 99-398kg/hm2, respectively. The recommended fertilization system of N in China’s peach soil was established preliminarily, which could provide a scientific basis for peach soil testing and fertilization.
