【摘要】 葡萄设施栽培中光照因素与果实质量密切相关,受覆膜影响室内透光率仅为65%～80%,设施中人为给光时,光照时数与质量、光合效率降低、架式不合理、叶幕遮挡等因素影响果实质量,要选择合适薄膜并加强保养,栽培设施结构合理,选择适宜的架式和补光措施。更多还原

【Abstract】 There was close relationship between sunlight factor and fruit quality in the grape greenhouse cultivation.Affected by the covering film, the inside transmittance was only to 65%～80%. In the greenhouse, the fruit quality was affected by the decrease of the time and quality of the sunlight, photosynthetic efficiency and unreasonable constructions, etc. It was significant to choose proper films and strengthen protection, as well as choose reasonable cultivation facilitates and supplementing sunlight measures.更多还原
