Application effect of walnut whole fruit fermentation liquid fertilizer on Chinese cabbage
In order to improve the utilization value of walnut,a series of processing processes and fermentation was car-ried out using walnut green fruit,skin and shell as raw materials to produce liquid fertilizer,the application effect of which was explored in vegetable planting.Pot experiments were conducted on Chinese cabbage,with four treatments:no fertilization(CK),single application of base fertilizer compound fertilizer(T1),single irrigation of 200 times walnut whole fruit fermentation liquid fertilizer(T2),and base fertilizer compound fertilizer+irrigation of 200 times walnut whole fruit fermentation liquid fertilizer(T3).The effects of walnut whole fruit fermentation liquid fertilizer were studied on the growth and quality of Chinese cabbage.The results showed that compared with CK,the application of walnut whole fruit fermentation liquid fertilizer could increase the growth indicators and yield of Chinese cabbage,but the appli-cation alone was lower than the combination and single application of base fertilizer compound fertilizer.The application of walnut whole fruit fermentation liquid fertilizer could increase the soluble sugar,soluble protein and vitamin C content of Chinese cabbage,and reduce the content of crude fiber.The effect of combined application with base fertilizer com-pound fertilizer was better than that of single application,but the content of soluble protein of Chinese cabbage were sig-nificantly lower than that of single application of base fertilizer compound fertilizer.In summary,the liquid fertilizer made from whole walnut fruit fermentation contains nutrients required for plant growth.After application,it can promote the growth and development of Chinese cabbage.However,due to its generally low nutritional components,combined with chemical fertilizers can significantly improve its growth indicators and quality.
