Effect of Lycium barbarum L. Root Restriction Cultivation Method on Plant Growth and Soil Bacterial Community Abundance

The root restriction of protected cultivation has been widely used to increase productivity and sustainability in modern agriculture. However, there have few studies wolfberry (Lycium barbarum) restriction, it is cultivated mostly by clean tillage. In this study, we measured the growth Lycium barbarum composition diversity bacterial community soil properties L. under different methods with restriction. results showed that X60 root-restriction treatment significantly increased canopy size (east–west), leaf length, width, number length new branches, concentrations chlorophyll K barbarum. N, P, groups were all higher than those CK. ratio N:P was greatest CK plants least X80, indicating X80 had a relatively weak effect on balance N:P. addition, improved fruit quality increasing organic matter carbon also fertilization efficiency promote plant growth. Moreover, high-throughput sequencing abundance bacteria Furthermore, total top 10 genera treatment. Redundancy analysis K, major factors affected community. A comprehensive comparison but reduced bacteria. yielded best Our findings provide an empirical reference for appropriate width.
