Abstract:

The experiment was conducted with 5-year-old Red Globe grape trees, studied using different covers on Red Globe grape winter test, by comparing the change of temperature, the winter conditions of grape branches, germination and the growth conditions of new shoots in the coming year, and comprehensive evaluation on cold effects of the special covers for Red Globe grape by Subordinate Function (SF). The results showed that the temperature around the branches higher 0.48-1.87℃ than the control after used different covers. After treated by covers in May, the number of the new branches, fruiting branches rate and the fruiting coefficient was higher than the control, the germination rate increased, the rate of cold branches decreased, the survival rate of self-rooted increased, shown strong growth potential, convenient and practical.
