Embodiment 1

[0023] A kind of high position grafting method that improves litchi high survival rate and high fruiting rate, comprises the following steps:

[0024] A, pretreatment: select 2 days before cutting the fringe of 3-year-old litchi mother tree, spray the protective agent containing thiophanate-methyl, copper rosinate, methyl bromide and water to litchi mother tree, the thiophanate-methyl in the described protective agent Parts by weight are 5 parts, 3 parts of copper rosinate, 18 parts of methyl bromide and 500 parts of water;

[0025] B. Selection and processing of scion: cut the scion on the litchi mother tree, flatten the interface on the back or side of the bud on the scion branch, see the xylem slightly, cut the surface 1.5 cm long, cut the interface obliquely on the back, and cut it into 40 Degree of slope, at the scion branch interface, use the scion branch medicament to smear and leave it to stand for 7 hours. The scion branch medicament component includes: 0.1 part of ro...

Embodiment 2

[0030] A kind of high position grafting method that improves litchi high survival rate and high fruiting rate, comprises the following steps:

[0031] A, pretreatment: select 3 days before the cutting fringe of 3-year-old litchi mother tree, spray the protective agent containing thiophanate-methyl, copper rosinate, methyl bromide and water to litchi mother tree, the thiophanate-methyl in the described protective agent Parts by weight are 15 parts, 9 parts of copper rosinate, 9 parts of methyl bromide and 700 parts of water;

[0032] B. Selection and processing of scion: cut the scion on the mother litchi tree, cut the joint on the opposite side or side of the bud on the scion branch, see the xylem slightly, cut the length of the surface by 2 cm, cut the short joint obliquely on the opposite side, and cut it into 30 Degree of slope, at the scion branch interface, use the scion branch medicament to smear and let it stand for 4 hours. The scion branch medicament component include...

Embodiment 3

[0037]A kind of high position grafting method that improves litchi high survival rate and high fruiting rate, comprises the following steps:

[0038] A, pretreatment: select 2 days before cutting fringe of 4-year-old litchi mother tree, spray the protective agent that contains thiophanate-methyl, copper rosinate, methyl bromide and water to litchi mother tree, the thiophanate-methyl in described protective agent The parts by weight are 10 parts, 7 parts of copper rosinate, 15 parts of methyl bromide and 600 parts of water;

[0039] B. Selection and processing of scion: cut the scion on the litchi mother tree, flatten the interface on the back or side of the bud on the scion branch, see the xylem slightly, and cut the length of the surface 1.8 cm, cut the interface obliquely on the opposite side, and cut it into 35 cm. Degree of slope, at the scion branch interface, use the scion branch medicament to smear and let it stand for 6 hours. The scion branch medicament component incl...

Abstract

The present invention discloses a high-position grafting method for improving high survival rate and high fruiting rate of litchi. The method comprises steps of pretreatment, selection and treatment of a scion, selection and treatment of a rootstock, grafting, management after grafting, etc. A nutrient is smeared after the grafting, so that grafted branches can keep moist and rapid growth of the grafted branches can also be promoted, and at the same time, insect-killing and sterilization are conducted to enable the branches not to be infected. The high-position grafting method enables the survival rate of the litchi to be as high as 90-95%, the fruiting rate to be 70-88%, and single fruit weight of the litchi to be 40-50 g, greatly improves economic efficiency and meets large demands of people for the litchi.

Description

technical field [0001] The invention relates to the technical field of litchi cultivation and management, in particular to a high-level grafting method for improving the high survival rate and high fruiting rate of litchi. Background technique [0002] Litchi (formal name used at school: Lichichinensis 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". The wood i...
