广西一年两熟葡萄栽培的气候基础

The climate elements for two-harvest-yearly grape cultivation in Guangxi

文章对广西种植葡萄的气候指标进行了详细分析,提出广西充足的光热资源可进行一年两收葡萄栽培,每年可收获夏冬两造葡萄;反季节的冬果生长期是在广西的旱季,符合葡萄专家们提出的葡萄适宜区的各项指标,是葡萄栽培所需的最佳气候环境,能生产出最优品质的果品供鲜食和酿酒;一年两收葡萄栽培模式,既解决了南方葡萄休眠期低温不够的难题,又能提高南方光热资源和土地利用率,值得大力推广。

This paper has analyzed detailedly the climate indexes selection for grape cultivation in Guangxi and indicated that the sufficient sunshine ＆ heat resources in Guangxi can afford two-harvest-yearly （summer and winter） grape cultivation. The winter cultivation is in the drought period accord with the indexes of grape growth suggested by experts so that it has the best climate elements to produce high-quality fruits for fresh consumption and wine-making. The two-harvest-yearly grape cultivation mode can solve the problem of short low temperature days in grape dormancy period as well as increase utilization rate of sunshine, heat and land in Southern China, hence the mode is worth to be promoted and extended.
