Abstract: In order to explore the application effect of vegetable waste fermentation liquid in agricultural cultivation,the influence of growth,quality and nutrient absorption of Chinese cabbage after using fermentation liquid.Been setting up 8 treatments by pot experiment,including CK,organic fertilizer(A1),fertilizer(A2),fermentation liquid(A3),organic+chemical fertilizer(B1),organic+fermentation liquid(B2),organic fertilizer+2/3 fertilizer+1/3 fermentation liquid(B3),organic fertilizer+1/3 fertilizer+2/3 fermentation liquid(B4).The growth indexes such as fresh weight and dry weight per plant,Vc and nitrate content,total nitrogen,total phosphorus and total potassium content,plant height,spread width and maximum leaf length/width were determined and analyzed.The results indicated that the fermentation had some effects on promoting growth,increasing yield and improving quality.The fermentation liquid was used in B3 and B4,compared with B1,the plant height,width,maximum leaf length and maximum leaf width of Chinese cabbage increased by 31.1%,28.7%,34.9% and 27.3%;Fresh weight and dry weight per plant increased by 89.4%,45.5%;The contents of nitrogen,phosphorus and potassium B4 increased by 57.3%,15.4%,181.8% in B4.After the application of fermentation,the content of nitrate in the plants was effectively reduced,the moisture content was increased,but the content of Vc was decreased.The study found that vegetable waste fermentation liquid could replace part of chemical fertilizer,and combined with organic fertilizer or chemical fertilizer.It could reduce applying chemical fertilizer and find a new way for recycling vegetable waste,also could contribute to promote crop growth,improve crop yield and quality.

Key words: Chinese cabbage, Vegetables waste, Fermentation, Quality
