(二)保护地葡萄的栽培类型保护地葡萄的栽培类型,是根据健芽开始时期的早晚和年内成熟采收茬次来区分的,年内成熟采收一次的,叫做促成栽培;年内成熟采收两次的,叫做促成兼延迟栽培。1.促成栽培在促成栽培中,根据催芽开始时期的早晚,可分为早促成栽培,促成栽培和一般促成栽培三种类型。而催芽开始时期的确定,又与葡萄植株的休眠生理和保护地种类及其是否进行人工加温有密切关系。(1)催芽开始时期的确定①葡萄休眠生理与催芽开始时期
(II) Types of Cultivation of Protected Grapes The types of cultivated grapes in protected areas are distinguished according to the early and late buds of the beginning of the Jian buds and the mature harvest stubble during the year. Once ripened and harvested once during the year, they are called forgery cultivation. During the year, mature harvests Twice, called to promote and delay cultivation. 1. Promote cultivation In promoting cultivation, according to the germination of the early period of time, can be divided into early to promote cultivation, promote cultivation and general promote cultivation of three types. The germination of the beginning of the determination, but also with grape plants dormancy physiology and protected areas and whether it is artificial warming is closely related to.
