Embodiment 1

[0026] A grafting method for longan cutting, comprising the following steps:

[0027] A. Scion and rootstock selection: the scion is selected from high-quality longan lignified cut strips, 0.6cm; the rootstock is selected from longan seedlings that are more than 1 year old, and the average cut height of each seedling is more than 20cm, and the cut thickness is 1 to 1.5cm;

[0028] B. Grafting preparation: the grafting time is March 10, 2013, on a cloudy day, cut the high-quality longan seedlings into 3cm long scions, keep 2-3 full bud eyes on the scion; remove the leaves;

[0029] C, grafting: cut off the scion epidermis on the flat side, the cut surface is 1-1.5cm long, 0.5-1cm wide, and the depth just reaches the xylem; the scion is cut to 2-5cm long; the rootstock diameter is selected to be slightly larger than the scion and the rootstock Cut off, then peel off from the cut surface towards the south, the depth can be seen in the xylem, and the width is consistent with the c...

Embodiment 2

[0036] A grafting method for longan cutting, comprising the following steps:

[0037] A. Scion and rootstock selection: the scion is selected from high-quality longan lignified cut strips, 0.7cm; the rootstock is selected from longan seedlings that are more than 1 year old, and the average cut height of each seedling is more than 20cm, and the cut thickness is 1.2-1.5cm;

[0038] B. Grafting preparation: The grafting time is February 25, 2014, on a cloudy day. Cut the high-quality longan seedlings into 2.5-3cm long scions, and keep 2-3 full bud eyes on the scion; remove the leaves;

[0039] C, grafting: cut off the scion epidermis on the flat side, the cut surface is 1-1.5cm long, 0.5-1cm wide, and the depth just reaches the xylem; the scion is cut to 2-5cm long; the rootstock diameter is selected to be slightly larger than the scion and the rootstock Cut off, then peel off from the cut surface towards the south, the depth can be seen in the xylem, and the width is consistent ...

Abstract

The invention provides a grafting method for longan cut-grafting. The grafting method comprises the following steps of scion and stock selection, grafting preparation, grafting and managing after grafting. A longan seedling is a wooden root of arbor, and the root system is well developed, so that the survival rate of grafting is guaranteed. The longan seedling belongs to one same family with a high-quality longan seedling, affinity of a scion and a stock is strong, the grafting success rate is greatly improved, and the speed of growth of the grafted grafting seedling is also accelerated. The longan seedling has stronger drought-resistant ability, the survival rate of grafting can be guaranteed under a drought condition, and blossoming and fruit bearing of the grafted longan seedling can be achieved within three years. The high-quality longan grafting method of the longan seedling is simple and convenient, the survival rate is high, the coverage rate of a longan high-quality variety is improved, and blossoming and fruit bearing of the longan can be realized in advance.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of plant grafting, in particular to a grafting method for cutting and grafting longan. [0003] 【Background technique】 [0004] In my country, longan 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 longan fruit. Longan seedlings are dicotyledonous plants that are less resistant to cold, so they are mostly distributed in tropical and subtropical regions of Asia, and are mainly produced in southern provinces such as the east, south and southeast of Guangxi, Guangdong, Fujian and the hillsides of Taiwan. Longan seedlings like warm and humid climates, and are not resistant to severe cold. The lowest temperature for wintering of longan 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 o...
