设施葡萄主栽品种需冷量测定及其应用研究

Measurement and Practical Study on Cold Requirement of Major Culture Varieties in the Cultureof Greenhouse Grape

根据葡萄生物学特性,采用水浸枝蔓法和试区12年来晚秋稳定通过≤7.2℃气温的平均初始日期,测算出目前设施葡萄栽培中矢富罗莎等6个主栽品种的需冷量及相应的适宜扣棚升温时间。依据需冷量、果实生育期、果品品质3指标,筛选出了河西5市日光温室葡萄高效栽培的适栽品种5个,对设施葡萄大面积推广栽培具有较高的实用价值。

Use specific property of grape biology. Adopt the method of soaking branches and tendrils in water and experimental area average dates for the first time that late autumn for the grape steadily survived the atmospheric temperature of smaller or equal than 7.2 ℃ for twelve years in experimental area. Have measured and calculated cold requirement and suitable time of covering greenhouse with plastic film of Shifuluosha etc 6 sorts of grapes of major culture. According to 3 kinds of weight indexes of cold requirement, fruit fertility period and fruit quality; have selected 5 sorts of suitable cultural varities of high-speed culture grapes in greenhouse at 5 area of Hexi. There are higher practical values for extending and culture grapes in greenhouse on a large scale.\;
