葡萄不同品种对设施环境的适应性

Environmental Adaptability of Different Grape Cultivars in Greenhouse

【目的】选择适宜设施栽培环境的葡萄品种。【方法】以22个5年生设施葡萄常用品种为试验材料,研究不同葡萄品种对设施环境的适应性,明确影响设施葡萄连年丰产的重要环境因子。【结果】设施栽培环境条件下连年丰产能力强的品种其耐弱光能力强,但耐低浓度CO2和耐高温能力不一定强;弱光是影响设施葡萄连年丰产的主要环境因素,而低浓度CO2和高温不是影响设施葡萄连年丰产的主要环境因素。【结论】红旗特早玫瑰、紫珍香、无核白鸡心、无核早红、红标无核、87-1、乍娜、莎巴珍珠、奥迪亚无核、香妃和红香妃等品种对设施栽培环境具有较强的适应性,连年丰产能力强。弱光是影响设施葡萄连年丰产的重要环境因素。

【Objective】The objective of this study is to lay a foundation for screening of the grape cultivars which are suitable for the protected cultivation environment.【Method】Twenty-two 5-year-old protected grape cultivars were used as experimental materials to study the adaptability of different grape cultivars under the protected environment and to make clear the important environmental factors which affect high yield in successive years of the protected grapes.【Result】The results showed that the grape cultivars with high-yielding capacity in successive years in the protected cultivation environment conditions have a better ability of resistance to low-light,but not necessarily strong resistance to low concentrations of CO2 and high temperature.Low light is the major environmental factor which affects high yield in successive years of the protected grapes,but low concentration of CO2 and high temperatures are not the major environmental factors.【Conclusion】Hongqitezaomeigui,Zizhenxiang,Centenial Seedless,Wuhezaohong,Hongbiaowuhe,87-1,Cardinal,Pearl of Csaba,Otilia Seedless,Xiangfei and Hongxiangfei have a higher environmental adaptability and high ability of sustainable productivity.Low light is an important environmental factor which affects high yield in successive years of the protected grapes.
