温室葡萄一年两熟果实品质差异研究

Study on the Difference of Fruit Quality in Two Ripe Greenhouse Grapes A Year

北方葡萄一年两熟技术是将促早栽培技术与延迟栽培技术有机结合的综合栽培方式,实现了葡萄第一熟在5—7月,第二熟在元旦、春节期间。通过对‘京香玉’‘瑞都科美’的物候期、果实性状与经济效益的调查分析认为,这两个品种适宜在温室内进行一年两熟栽培,但不同品种间在物候期、果实性状与产量方面差异较大,造成这种差异主要与光照和温度的变化有关。

The northern two ripe grapes a year was an comprehensive cultivation mode,which combination of early cultivation technology and the delayed cultivation technique. Achieve the first ripe grapes mature in May —July,the second ripe mature during the New Year＇s day,Spring Festival. Through investigation and analysis of ‘Jingxiangyu＇ and ‘Ruidukemei＇ varieties of phenophase,fruit characters, and economic benefits.We found two varieties suitable for grape in greenhouse two ripe in a year. After implement two ripe,varieties has much differences in phenophase,fruit traits and yield. The differences have associated with the change of light and temperature.
