[Objective]This paper aimed to explore the high-yield cultivation techniques of blueberry soil mulching in greenhouse.[Method]In order to explore the cultivation technology of soil mulch for high yield of blueberry in greenhouse,In this paper,four treatments of crushed straw,pine sawdust,pine needles and control(CK)were used to study the effects of different mulching techniques on the growth and fruit quality of blueberry soil.[Result]The results showed that among the four treatments,the plant height,crown width,basal branch length,basal branch thickness,elongated branch length,and elongated branch thickness of straw treatment were higher than those of sawdust,pine needles,and control plants.The single fruit weight of straw treatment was 2.9 g,and the contents of soluble solid,soluble sugar and vitamin C were the highest,which were 13.0%,7.58%and 587.06 mg/kg,respectively.[Conclusion]It was to provide theoretical and technical reference for solving the obstacles of high temperature and strong light during the growth period of blueberry to the development of greenhouse blueberry production.
