Natural Grass Cultivation Management Improves Apple Fruit Quality by Regulating Soil Mineral Nitrogen Content and Carbon-Nitrogen Metabolism.

ABSTRACT: Orchard grass cultivation management is an effective measure to safeguard the sustainable development of the fruit industry in China. However, details of the influence of natural sod culture management on carbon (C)-nitrogen (N) nutrition of trees and fruit quality in Hanfu apple orchards are lacking. Therefore, a field experiment was conducted, which consisted of two treatments: clean tillage (CT) and natural grass cultivation (NG). Results revealed that NG treatment contributed to the increases in soil organic matter (SOM), total N, and soil NH₄⁺-N at depths of 0-20 cm and 20-40 cm, while the soil NO₃^--N concentration under NG treatment was significantly decreased at the same depth, within the range of 0-200 cm of the soil profile, compared wit
