| Abstract: |
| Abstract：【Objective】To study the effects on quality and yield of Chinese Cabbage by using of drip fertilization and regulating cultivation for northeast pickled cabbage.【Method】Two factors were designed for comparative tests, irrigation method and fertilization ratio respectively, the changes of sensory quality and the effects of lactic acid in fermentation were focused researched on Chinese cabbage. The important soil and environmental parameters were monitored in real time during the whole growth cycle of Chinese cabbage and drip fertilization regulating cultivation by internet of things cloud platform, according to the nutrients data of the soil and the law of fertilizer absorption in different growth stages of Chinese cabbage, the ratio of drip fertilization and the amount of potassium fertilizer usage were adjusted. The effects of drip fertilization and regulating cultivation were checkout systematically through the comparative analysis of the quality, sugar content and lactic acid in fermentation process of Chinese cabbage.【Result】The comparative tests indicated that the side effect caused by low temperature water impacting Chinese cabbage could be avoided through drip fertilization which can reduce disease and improve output. Compared with the traditional planting method, fertilizer saving 50% and water saving 40%, Chinese cabbage has the quality of uniform plant height, full and tight heart, high net weight rate and no disease, the yield of Chinese cabbage reaches 5000kg per 667m2, which is 25% higher than compared group, net income increased 90%. Under the regulating cultivation condition in this paper, the sugar content of Chinese cabbage increased 20.6% maximum, through comparative tests by lactic acid in fermentation, the output rate of pickled cabbage increased by 2.5% using Chinese cabbage which planted by drip fertilization, the acidity pH decreased significantly during lactic acid in fermentation, the fermenting-ripening is achieved 24h in advance than compared group, the fermentation cycle was compressed about 3%, which helpful to improve fermentation efficiency, energy saving and consumption reducing.【Conclusion】The normalization planting of high quality Chinese cabbage can be realized by comprehensive?application?of the regulating cultivation methods such as soil testing for fertilizer, drip fertilization using water soluble compound fertilizer, soil nutrient monitoring online, and controlling potassium fertilizer during the stage?of?heading?in?Chinese?cabbage. |
