Embodiment 1

[0025] A method for grafting and raising seedlings of litchi, comprising planting of rootstocks, collection and processing of scions, grafting operations, and post-grafting management, specifically:

[0026] (1) The planting of rootstock: collect the local wild lychee fruit with plump pulp and dark red color, remove the pulp and refrigerate the wild lychee seeds for 10 days, then soak them in 300ppm gibberellin solution for 12 hours, and dry them naturally in the shade; Wild litchi seeds are placed in a He-Ne laser with a wavelength of 800nm, a spot diameter of 5mm, a power of 650mW, and a radiation dose of 9.8J / cm at a temperature of 22-25°C. 2 1. The irradiation distance is 30cm and irradiated for 30s; mix the fine river sand and wood chips according to the mass ratio of 3:1 and spray with water, place the irradiated seeds in the mixture of river sand and wood chips to accelerate germination; after the seeds germinate Sow the rootstock seedling, pick the heart when the roots...

Embodiment 2

[0032] A method for grafting and raising seedlings of litchi, comprising planting of rootstocks, collection and processing of scions, grafting operations, and post-grafting management, specifically:

[0033](1) The planting of rootstock: collect the local wild lychee fruit with plump pulp and dark red color, remove the pulp and refrigerate the wild lychee seeds for 12 days, then soak them in 350ppm gibberellin solution for 11 hours, and dry them naturally in the shade; Wild litchi seeds are placed in a He-Ne laser at a temperature of 22-25°C with a wavelength of 800nm, a spot diameter of 6mm, a power of 650mW, and a radiation dose of 9.8J / cm 2 1. The radiation distance is 30cm and irradiated for 32s; mix the fine river sand and sawdust according to the mass ratio of 4:1 and spray it with water, and place the irradiated seeds in the mixture of river sand and sawdust to accelerate germination; after the seeds germinate Sow the rootstock seedling, pick the heart when the rootstoc...

Embodiment 3

[0039] A method for grafting and raising seedlings of litchi, comprising planting of rootstocks, collection and processing of scions, grafting operations, and post-grafting management, specifically:

[0040] (1) The planting of rootstock: collect the local wild lychee fruit with plump pulp and dark red color, after removing the pulp, the wild lychee seeds are refrigerated for 15 days, then soaked in 400ppm gibberellin solution for 10 hours, and dry naturally in the shade; Wild litchi seeds are placed in a He-Ne laser with a wavelength of 800nm, a spot diameter of 8mm, a power of 650mW, and a radiation dose of 9.8J / cm at a temperature of 22-25°C. 2 1. The radiation distance is 30cm and irradiated for 35s; mix the fine river sand and wood chips according to the mass ratio of 5:1 and spray with water, place the irradiated seeds in the mixture of river sand and wood chips to accelerate germination; after the seeds germinate Sow the rootstock seedling, pick the heart when the roots...

Abstract

The invention provides a method for culturing litchi seedling by grafting, belonging to the technical field of agricultural planting. The seedling culturing method comprises the steps of planting a tree stock, collecting and treating cion, grafting, and managing after grafting. The tree stock is treated by the following steps: treating by adopting laser radiation, and sowing after being soaked with auxin, thus obtaining tree stock with high survival rate; the cion is treated by the following steps: spraying auxin and a protecting agent to a parent tree and performing grafting operation on the cion which is soaked with a nutrient solution; the grafted cion is sealed with wet soil. By adopting the seedling culturing method, high grafting survival rate can be achieved, and the cultured litchi seedlings have the characteristic of high yield.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of agricultural planting, in particular to a method for grafting litchi seedlings. [0003] 【Background technique】 [0004] Litchi (formal name used at school: Lichi chinensis Sonn.) originates in southern China, is subtropical fruit tree, evergreen tree, about 10 meters high. The peel has scale-like protrusions, bright red, purple. The pulp is translucent and creamy when it is fresh, and has a delicious taste, but it is not resistant to storage. Together with bananas, pineapples and longan, lychees are known as the "four major fruits in the southern country". Litchi is famous for Yang Guifei's favorite food, which made Du Mu write the famous sentence "When a concubine laughs on a ride in the world of mortals, no one knows it is litchi". Litchi is hot in nature, and eating too much is easy to get angry, and can cause "lychee disease". Lychee tastes sweet, sour, warm in nature, enters the heart, s...
