Effects of Returning Green Manure on Soil Nutrients,Enzyme Activity and Fruit Quality in Vineyards
To understand the effects of different returning methods on soil nutrients,enzyme activity,and fruit quality in vineyards after inter-cropping rape as green manure.Through field experiments,three treatments were set up:a single grape tree without green manure,intercropping rape with green manure mulching,and intercropping rape with green manure ploughing.The results showed that the organic matter,total N,al-kali-hydrolyzed N,available P,available K,urease,and alkaline phosphatase activity in the 0-20 cm soil layer were the highest under the ploughing,increased significantly by 50.00％,19.40％,16.47％,25.38％,13.69％,82.35％ and 26.87％ compared to the control,respective-ly.In the 20-40 cm soil layer,compared with control soil pH,total N,available K,urease,and sucrase activities significantly increased by 3.70％,5.07％,44.68％,40.43％,14.71％,20.85％,32.00％,35.50％,11.85％ and 29.84％,respectively,while the difference between mulching and ploughing was not significant.The hundred leaf dry weight,ear weight,soluble sugar,sugar acid to ratio,and vitamin C content of grapes were significantly higher than those of the control under mulching and ploughing treatments,and the highest was observed under ploug-hing treatments.Intercropping rape green manure could increase the soil nutrient content,promote grape growth,and improve fruit quality,and the effect of green manure ploughing was better than that of green manure mulching.
