Embodiment 1

[0021] Litchi grafting method of the present invention, comprises the following steps:

[0022] A, scion and rootstock selection: the scion selects high-quality litchi lignified branches with a thickness of 3 mm; the stock selects 1-year-old litchi seedlings, and the average branch height of each seedling is 20 cm, and the thickness of the branches is 20 mm;

[0023] B. Grafting preparation: the grafting time is March 10, 2010, on a cloudy day, cut the high-quality litchi seedlings to the scion with a length of 3 cm, and keep 2-3 full bud eyes on the scion; remove the leaves;

[0024] C, grafting: the scion epidermis on the flat side is peeled off, the cut surface is 1cm long, wide 0.5cm, and the depth has just reached the xylem; the scion is cut to 2cm long; the stock is cut off at a position where the rootstock diameter is slightly larger than the scion, and then from the section The epidermis facing the south is peeled off, the depth can be seen in the xylem, and the width ...

Embodiment 2

[0033] Litchi grafting method of the present invention, comprises the following steps:

[0034] A, scion and rootstock selection: the scion selects high-quality litchi lignified branches with a thickness of 8 mm; the stock selects 4-year-old litchi seedlings, and the average branch height of each seedling is 30 cm, and the thickness of the branches is 30 mm;

[0035] B. Grafting preparation: the grafting time is February 25, 2010, on a cloudy day, cut the high-quality litchi seedlings to the scion with a length of 2.5-3cm, and keep 2-3 full bud eyes on the scion; remove the leaves;

[0036] C, grafting: cut off the scion epidermis on the flat side, the cut surface is 1.5cm long, 1cm wide, and the depth just reaches the xylem; cut the scion to 5cm long; select the position where the rootstock diameter is slightly larger than the scion to cut off the rootstock, and then from the section toward The epidermis on the south side is peeled off, the depth can be seen in the xylem, and...

Abstract

The invention provides a litchi grafting method, which comprises the following steps of scion and stock selection, grafting preparation, grafting and post-grafting management. Seedling litchi seedlings have arbor wood roots, the root systems are developed, and the grafting survival rate is ensured through selecting the seedling litchi seedlings as stocks; the seedling litchi seedlings and high-quality litchi seedlings belong to one family, the affinity between scions and stocks is high, the grafting success rate is greatly improved, and the growth speed of the grafted seedlings after the grafting can also be accelerated; the litchi seedlings have higher drought resistance capability, and the grafting survival rate can be ensured under the drought conditions, so the grafted litchi seedlings can bloom and bear fruit in three years. The litchi grafting method has the advantages that simplicity and convenience are realized, the survival rate is high, the coverage rate of high-quality litchi varieties can be improved, and the advanced blooming and fruiting of litchi can be realized.

Description

technical field [0001] The invention relates to the field of plant grafting, in particular to a litchi grafting method. Background technique [0002] In my country, lychee fruit has been a favorite fruit since ancient times. It tastes sweet and mellow but not greasy, and it is also an excellent tonic. The fruit can be dried into dried lychee fruit. Lychee seedlings are dicotyledonous plants, which are less 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. Litchi seedlings like warm and humid climates, and are not tolerant to severe cold. The minimum temperature for overwintering litchi seedlings is not lower than 0°C. Once the temperature is lower than 0°C, the normal physiological activities of the plants will be affected, the absorption capacity of the roots will be weakened, and the tende...
