Abstract: 【Objective】To explore the effects of different organic materials combined with chemical fertilizers on the yield,quality of mountain-grown Actinidia chinensis Planch. and soil nutrients in southern Shaanxi,and to provide a basis for high-quality and high-yield cultivation of mountain-grown A. chinensis Planch..【Methods】Ten-year-old Xuxiang A. chinensis Planch. was used as the experimental material,and five treatments were set up：no fertilization（CK）,application of chemical fertilizer alone（F）,chemical fertilizer+cow manure+kitchen waste（FCF）,chemical fertilizer+cow manure+branches（FCB）,chemical fertilizer+kitchen waste+branches（FFB）. Earthworms and microbial inoculants were added to each fertilization treatment. The effects of different treatments on leaf growth,fruit yield,quality of mountain-grown A. chinensis Planch. and soil nutrients were analyzed.【Results】The contents of total nitrogen,total phosphorus and total potassium in leaves and fruits of each treatment were significantly higher than those of CK（P<0.05）;among them,FCF treatment was the best,which was 58.89%,68.42%,49.31% and 60.00%,59.09%,44.05% higher than CK,respectively. The fresh weight per 100 leaves,dry weight per 100 leaves,water content,leaf area,thickness per 100 leaves and SPAD value in leaves of each treatment were significantly higher than those in CK（P<0.05）,and FCF treatment was the best. The single fruit weight,yield per plant,firmness,soluble sugar content,sugar-acid ratio,soluble solid content,vitamin C content and fruit shape index of A. chinensis Planch. in each treatment were significantly higher than CK（P<0.05）;among them,the comprehensive effect of FCF treatment was the best,which was 65.97%,56.04%,30.80%,50.06%,65.39%,42.22%,51.11% and 5.60% higher than CK,respectively. The yields and profits of F,FCF,FCB and FFB treatments were higher than those of CK,and the FCF treatment was the best,which was 31.31 t/hm² and 187 500 yuan/hm²,respectively. All treatments significantly increased soil nutrient content;among them,FCF treatment had the best effect and the contents of soil organic matter,alkali-hydrolyzable nitrogen,available phosphorus and available potassium in 0-20 cm soil layer increased by 79.87%,67.37%,131.21% and 89.56%,respectively,compared with CK.【Conclusion】Chemical fertilizer+cow manure+kitchen waste treatment,together with the addition of earthworms and microbial inoculants,can achieve high quality and high yield of mountain-grown A. chinensis Planch.,increase economic benefits and improve soil fertility. It is a suitable cultivation and fertilization regime for high quality and high yield of mountain-grown A. chinensis Planch. in southern Shaanxi.
