广西南部巨峰葡萄一年两收栽培模式研究

One-year-two-harvest cultural technique system for Kyoho grape in southern region of Guangxi

为了充分利用广西南部优越的光热气候资源，根据巨蜂葡萄易开花的特性，研究发展了葡萄一年两收栽培模式，通过采用15～20倍50％单氰胺破眠荆打破葡萄休眠，1年内收获了生育期完全不重叠的两茬产量，既解决了南方葡萄冬季休眠期低温不够的难题，又使葡萄在夏季修剪和促花剂处理后萌发结冬果。该技术在合理利用南方光照、温度及土地资源的基础上，使臣蜂品种优良的风味品质得到充分表现，大大提高了南方葡萄生产的产量、质量和效益，因而具有广阔的推广应用前景。

In order to fully utilize the superior climate condition in southern region of Guangxi, China, a one-year-two-harvest cultural technique system for Kyoho grape was developed by adopting 15 -20 times diluted 50 % monocyanamide solution treatment to break grape dormancy,which relieved the limit of over temperature for breaking grape dormancy in this region. After summer harvest, appropriate pruning and chemical treatment promoted the other flowering and frniting,which realized the.second harvest in late December. The cultural technique system exploited the natural resources of sunlight, temperature and soil, and provided with good conditions for realizing the elite quality of Kyoho grape ,and finally improving the field,quality and income benefit of the production,showing a bright application prospect.
