红提葡萄引种及抗寒栽培技术总结

Study on the Introduction and Cultivation Demonstration of The Red Globe Grape

本文根据红提葡萄6年引种、试栽和示范推广的经验, 总结出一套适合宁夏土壤气候条件的抗寒栽培技术模式, 主要内容包括: 园地的选择、规划,开沟施肥、改良土壤,以及合理整形、修剪,科学施肥、控制产量、提高果实品质,强化防寒、防霜冻等。主要经济技术指标是:栽植时需采用嫁接苗,采取单蔓整形,第二年少量结果,第三至四年株产2～3kg, 第五年进入盛果期,株产4～5kg, 单产18000～22500kg/hm2。单穗留果粒数60～80粒, 并采用套袋,改善着色, 果实含糖量18%以上。

Based on the cultivation demonstration and extension experience in a period of six years for Red Globe grape,A set of cold resistant cultivation technologies has been summarized, which is suit the soil and climatic condition in Ningxiaarea. The main contents are including the following aspects: Site Choosing, planting plan, ditching fertilization, soil im-provement ,rationed training and pruning ,scientific fertilization, output control, quality improvement and intensified precau-tions against cold and frost.The main technological norms are as follows :using cold resistant grafted seedlings single stem training form , minimizingthe output in the following year and 2 to 3 kg of fruit production in the third to fourth year after planting. The maximum fruitproduction in the Fifth year after planting reached 4 to 5kg of fruit production per plant and l8,000～22, 500kg/hm2. The numberof the fruits per cluster must be controlled to 60～80 fruits, paper cover for the clusters to improve the color, and sugar contentis well above 18 percent .
