| 摘要 | [Objectives] This study was conducted to promote the high-yield and high-quality cultivation of non-heading Chinese cabbag. [Methods] Two non-heading Chinese cabbage varieties, ‘Suzhouqing’ and ‘Huakaifugui’, were used as experimental materials. Five concentrations of amino polysaccharides, A (1 000 times solution), B (500 times solution), C (100 times solution), D (10 times solution), and CK, were set up to investigate the effects of amino polysaccharides on nitrogen metabolism, chlorophyll synthesis, dry matter accumulation, and nutritional quality in non-heading Chinese cabbage leaves. [Results] Nitrate reductase and glutamine synthetase activities in the leaves of the two non-heading Chinese cabbage varieties were significantly enhanced, and the free amino acid content, chlorophyll content, soluble protein content, vitamin C content and plant dry weight increased significantly, while the nitrate nitrogen content decreased significantly. Amino polysaccharides facilitated nitrogen conversion and amino acid synthesis in non-heading Chinese cabbage, thereby promoting growth, increasing yield, and improving quality. The application effect of high concentration amino polysaccharide solutions (100 times and 10 times dilutions) was better. [Conclusions] This study provides a theoretical foundation for exploring the application potential of amino polysaccharides in high-yield and high-quality cultivation of non-heading Chinese cabbage. |
