Evaluation of the Effects of Returning Apple Shoots In Situ on Soil Quality in an Apple Orchard

Fruit tree shoots are potential useful resources that rich in carbohydrates and inorganic nutrients but not typically utilized sustainable agriculture. Our objective was to evaluate the soil properties quality of an orchard after returning apple situ investigate contribution rate as exogenous source organic carbon for fertility amendment root domain. One-year-old were pruned spring before budding, chopped into 10 cm sections placed on surface. Soil samples collected first year third shoots. Principal component analysis, Pearson correlation analysis index (SQI) comprehensive methods, combined with fuzzy mathematics, adopted effects quality, including indicators, exchangeable cations, neutral sugar amino acids. Increases (SOC), available potassium (K), phosphorus (P) observed different layers returned over time. The total nitrogen (N) content decreased by 18.75% 13.79% 0–20 20–40 layers, respectively, year, increased significantly year. Significant increases cations (Na+, Ca2+, Mg2+) layer also shoots, compared control. In addition, obvious accumulation glucose xylose controls water-soluble free acid contents 1.08- 1.16-times higher, than those layers. SQI higher other treatments layer. This study suggests abandoned used a supplementary orchards enhanced regulated micro environment, improved overall quality.
