Psidium guajave tree grafting method

Abstract

The invention provides a psidium guajave tree grafting method which comprises the following steps of selection of a scion and a seedling sapling stock, management before grafting of the seedling sapling stock, grafting, application of a grafting method and management after grafting. A seedling psidium guajave sapling is woody rooted and the root system of the sapling is relatively developed, so that the survival rate of grafting is ensured; the seedling psidium guajave sapling and a high-quality psidium guajave tree belong to the same family and the scion has strong affinity with the stock, so that the success rate of grafting is greatly improved and the growing speed of the grafted tree after grafting is also improved; the psidium guajave seedling sapling has strong drought resistance and low-temperature resistance and under the drought and low temperature conditions, the survival rate of grafting can be ensured, so that the grafted psidium guajave sapling can blossom and bear fruits one year after being transplanted and also has capacity that the grafted psidium guajave sapling can pass the winter in the air and is easy to survive after being transplanted. The method of grafting the psidium guajave sapling with the high-quality psidium guajave tree, which is provided by the invention, is simple and convenient and has the high survival rate; the coverage rate of the high-quality psidium guajave varieties is improved; popularization of the improved varieties of psidium guajave is implemented.

Description

technical field [0001] The invention relates to the field of plant grafting, in particular to a guava tree grafting method. Background technique [0002] In my country, guava fruit has always been a favorite fruit, because it tastes sweet and mellow but not greasy, and it is also an excellent tonic. The fruit can be eaten fresh. Guava trees are not cold-resistant, so they are mostly distributed in tropical and subtropical regions of Asia. They are mainly produced in southern provinces such as the east, south and southeast of Guangxi, Guangdong, Fujian and the hillsides of Taiwan. Guava trees like warm and humid climates, but are not tolerant to severe cold. The lowest temperature for guava trees overwintering is not lower than 0°C. Once the temperature is lower than 0°C, the normal physiological activities of the plant will be affected, the absorption capacity of the roots will be weakened, and the shoots and leaves of the plant will wilt.

Problems solved by technology

[0003] Guava saplings are fruit trees grown directly from ordinary guava seeds. Generally, the trees are more than 3 years old before they begin to bloom and bear fruit. However, the fruit produced is small and the yield is low. The tree shape is tall and difficult to manage, but the root system is developed. Strong vegetative growth
