Embodiment 1

[0025] A kind of guava tree grafting method, comprises the following steps:

[0026] A. Selection of scion and rootstock: The scion is selected from high-quality guava lignified branches with a thickness of 5-10 mm in diameter; the rootstock is selected from guava seedlings that are more than 1 year old, and the average height of each seedling is 200-300 mm. mm high, the stem thickness is 10~20mm;

[0027] B. Grafting preparation: The grafting time is February 16, 2011, on a cloudy day, cut the high-quality guava branches to the scion with a length of 2 cm, and keep 1-2 full bud eyes on the scion; remove the leaves;

[0028] C. Grafting: Hold the scion in your hand, cut the lower end of the scion into a bevel, the bevel becomes tongue-shaped, the bevel is smooth, and the depth just reaches the xylem, cut the scion to 2cm long; cut off the rootstock from the joint, and then face south from the section The skin of the scion is peeled off, the depth is seen in the xylem, and the...

Embodiment 2

[0035] A kind of guava tree grafting method, comprises the following steps:

[0036] A. Scion and rootstock selection: The scion is made of high-quality guava lignified branches with an average diameter of about 10 mm; the rootstock is selected from guava seedlings that are more than 1 year old, and the average height of each seedling is more than 250 mm, and the thickness of the trunk is 10 mm. ~20mm;

[0037] B. Grafting preparation: The grafting time is May 25, 2011, on a cloudy day, cut the high-quality guava branches to the scion with a length of 1-2cm, and keep 1-2 full bud eyes on the scion; remove the leaves;

[0038] C. Grafting: Hold the scion in your hand, cut the lower end of the scion into a bevel, the bevel is tongue-shaped, the bevel is smooth, and the depth is just to the xylem; cut the scion to 1~2cm long; cut off the rootstock from the interface, and then from the cross section The epidermis facing the south is peeled off, the depth can be seen in the xylem,...

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. [0003] Guava saplings are fruit...
