摘　　要：[Objectives] The ecological environment of orchard has a direct impact on fruit quality,and straw mulching can effectively improve the physicochemical indicators of orchard soil,so as to achieve environmental protection and yield increase.[Methods]Tests were carried out for 3 consecutive years of mulching straw in vineyard of southern Jiangsu Province.[Results]The results showed that mulching straw continuously could effectively improve soil physicochemical properties,weed controlling effect,and the photosynthetic rate of leaves,as well as the yield and quality of grapes.The contents of total nitrogen,available phosphorus,quickacting potassium and organic matter increased up to 91.67%,259.76%,442.39% and 34.30%,respectively.Soil bulk density decreased by 7.15%,and the weed plant control effect reached 87.45%.The increased of fresh weight was up to 93.55%,and the increase of the leaf parenthetical rate was up to 18.24%.The increases of soluble solids content and single grain weight reached up to 8.82% and 12.75%.The rate of dehiscent fruit was decreased by 50.89%.The grape could pick for sale 3 days ahead,and the increase of unit area yield reached up to 13.16%.[Conclusions]Straw mulching cultivation in vineyard is a good model for efficient recycling of crop straw and safe production of quality grape,and it provides a new technical approach for straw utilization,promising with good economic and ecological benefits.[Objectives] The ecological environment of orchard has a direct impact on fruit quality,and straw mulching can effectively improve the physicochemical indicators of orchard soil,so as to achieve environmental protection and yield increase.[Methods]Tests were carried out for 3 consecutive years of mulching straw in vineyard of southern Jiangsu Province.[Results]The results showed that mulching straw continuously could effectively improve soil physicochemical properties,weed controlling effect,and the photosynthetic rate of leaves,as well as the yield and quality of grapes.The contents of total nitrogen,available phosphorus,quickacting potassium and organic matter increased up to 91.67%,259.76%,442.39% and 34.30%,respectively.Soil bulk density decreased by 7.15%,and the weed plant control effect reached 87.45%.The increased of fresh weight was up to 93.55%,and the increase of the leaf parenthetical rate was up to 18.24%.The increases of soluble solids content and single grain weight reached up to 8.82% and 12.75%.The rate of dehiscent fruit was decreased by 50.89%.The grape could pick for sale 3 days ahead,and the increase of unit area yield reached up to 13.16%.[Conclusions]Straw mulching cultivation in vineyard is a good model for efficient recycling of crop straw and safe production of quality grape,and it provides a new technical approach for straw utilization,promising with good economic and ecological benefits.
