Psidium guajave tree grafting method

Abstract

The invention provides a psidium guajave tree grafting method. The psidium guajave tree grafting method comprises following steps of scion and rootstock selection; grafting preparation; grafting; and management after grafting. A seedling psidium guajave sapling has an arbor woody root, the root system of the sapling is developed, and the grafting survival rate is guaranteed; the seedling psidium guajave sapling and a high-quality psidium guajave sapling belong to the same family and the scion has strong affinity with the stock, so that the success rate of grafting is greatly increased and the growing speed of the grafted sapling after grafting is also increased; the psidium guajave seedling sapling has strong drought resistance, and under the drought condition, the grafting survival rate can be ensured, so that the grafted psidium guajave sapling can blossom and bear fruits within two years. The method of grafting the seedling psidium guajave sapling with the high-quality psidium guajave sapling is simple and convenient and has the high survival rate; the coverage rate of the high-quality psidium guajave varieties is increased; and the fact that the psidium guajave tree blossoms and bears fruits in advance is achieved.
