葡萄一年二季结果栽培技术研究

葡萄是果树中花芽较易形成的树种之一，利用这一特性进行二次结果并在生产上运用，已成为葡萄业主进行调节产期供应，提高种植效益的一种手段。南方热量资源丰富，光照强，降温晚，采用全部落叶修剪，破眠催芽，保根保叶，达到葡萄一年二季结果即夏果与秋果。同时测定各处理间浆果大小，糖份含量，及结果枝条氮素与醣类的累积消耗、生长情形，以 探讨葡萄不同产期之营养生长和生殖生长间的生理变化。

The technical research of the grape plant obtain bear twice fruits in a year

Grape is a plant of fruit trees which its flower buds are easy in growing on. So that special character may be obtain bear twice fruits used in production. But we must to regulate the time of produce. It have become a mean to raise the per unit yield. In South of China, there are rich in natural resources, as more quantity of heat and illumination is stronger and the temperature is drop slow in autumn. So that to adopt pruning ,it help to destroy dormancy and hasten growing buds, keep the leaps and roots in growing. That may be to bear fruit during summer and autumn in a year. In the meantime, We must to determined fruits on size、sugar degree、with “N nutrient” content of fruit branches, and carbohydrates accumulated or consume those, and the grapes growing conditions. So that may be inquire into physiological changing in differ phases of nutrition growing and reproduction growing of the grapes.
