东南沿海地区大棚葡萄促早熟的影响因素及有效措施

Influencing factors and measures to promote early maturity of greenhouse grape in southeast coastal region

大棚促早栽培可以使葡萄提早成熟,一是可以实现早销售价格高,增加收益;二是能够有效起到避灾、减灾的效果;三是避免霜霉病的发生;四是缓解旺销期销售难的问题。生产上通过提早封膜、多次调控棚温、使用破眠剂、增加叶幕透光度、适产栽培等措施都可以达到促早熟的效果,可以解决大棚促早熟栽培生产上无法提早成熟,双膜栽培的成熟期晚于单膜栽培的问题。

The main purpose of early maturity cultivation of greenhouse grape was to increase efficiency. First, it could achieve early sales with high prices and increase profits; second, it could effectively play a role in avoiding disasters and reduce disasters; third, it could prevent downy mildew from occurring; and fourth, it could ease sales during strong sales. In the production, the methods of promoting early maturing could be achieved by early sealing membrane, multiple control of the greenhouse temperature, use of materials for breaking dormancy, increase of the transmittance of the leaf screen, and optimum cultivation. The maturity of double-membrane cultivation was later than that of single-membrane cultivation.
