Grape cuttings multiply, mostly in the spring. In the summer and autumn, the cutting propagation of grapes is generally difficult. I used a variety of treatments as a test, summed up a method, is briefly described as follows: First, the choice of shoots Select the buds with just sprouting grape branches, cut, cut the leaves, according to the length of about 15 cm, at least The requirements of a bud just germinating, cutting the cutting branches. Second, the cutting method to clean the sand as a seedbed. The cut grape branches will be required to be angled at about 45 degrees from the sand bed surface, inserted obliquely into the sand bed, and ensure that a bud just sprouting is buried about 1 cm below the sand bed surface, and there is no sprouting The bud shows sand surface. After cutting, keep the sand bed moist and avoid direct sunlight. Third, changes in cutting branches Cutting about 10 days after cutting, sprouting buds emerged from the sand bed surface to grow green. About 20 days after cutting, the buds where the growing buds grow have adventitious roots. About 35 days after the cutting, the buds that have grown have spread 2-3 leaves, and the section where it is located has grown a large number of young roots. Thus, the cuttings have been successful. The method of cutting the survival rate is generally up to 80%. The key to this method is to bury shallow buds in moist sand. Because, if the newly sprouted bud is exposed on the sand bed, the bud will germinate and grow too quickly, but it will not induce the occurrence and growth of the root in time, and eventually it will lose water and wither. If it is buried too deeply, the bud can germinate. There are also roots in growth. However, it is difficult for buds to break through the sand bed and eventually fail to survive. Only the buds that have just sprouted are immersed in a submerged area about 1 cm below the wet sand surface. The buds slowly expose the sand surface and induce new roots in a timely manner. This results in the balance of water absorption and loss, and finally the plants survive. China Agricultural Network Editor
