核桃全果发酵液体肥在白菜上的应用效果

Application effect of walnut whole fruit fermentation liquid fertilizer on Chinese cabbage

为提高核桃的利用价值,以核桃青果、皮、壳为原料经一系列加工工序和发酵后制作为液体肥,探讨液体肥在蔬菜种植中的应用效果。以白菜为试验材料进行盆栽试验,设置不施肥(CK)、单施基肥复合肥(T1)、单浇灌200倍核桃全果发酵液体肥(T2)、基肥复合肥+浇灌200倍核桃全果发酵液体肥(T3)4个处理,研究核桃全果发酵液体肥对白菜生长与品质的影响。结果表明,与CK相比,施用核桃全果发酵液体肥能提高白菜的生长指标,提高产量,但单独施用的效果低于与基肥复合肥配施、单施基肥复合肥处理;施用核桃全果发酵液体肥可提高白菜的可溶性糖和可溶性蛋白含量,降低粗纤维含量,而与基肥复合肥配施比单独施用效果好,但白菜可溶性蛋白含量显著低于单施基肥复合肥处理。综上所述,以核桃全果发酵后制作的液体肥含有植物生长所需的养分,施用后能促进白菜的生长发育,因其营养组分总体偏低,与化肥配合施用能显著提高其生长指标和品质。

In order to improve the utilization value of walnut,a series of processing processes and fermentation was carried 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 application 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 compound fertilizer was better than that of single application,but the content of soluble protein of Chinese cabbage were significantly 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.
