Problems solved by technology

These star anise forests are mainly afforested by seedlings. Due to gene heterozygosity under seedling propagation, the plant traits in the stand are greatly differentiated. There are more inferior plants and fewer high-yielding and good-quality plants, resulting in very low yield per unit area. Or the quality is uneven, and the annual output is unstable
[0003] However, the star anise seed forest has tall plants, wide crowns, and it is difficult to pick fruits. Under the current market trend of star anise picking labor costs rising year by year and star anise prices continuing to slump, the economic benefits of operating star anise seed forest stands have dropped significantly or even lost money

Embodiment 1

[0028] A dwarf and high-yield grafting technique for star anise, comprising the following steps:

[0029] S1, select rootstock: select well-developed root system, strong resistance, no damage by diseases and insect pests and a height of 10 centimeters from the ground, a rootstock with a root diameter of 0.5-2 centimeters;

[0030] S2, collect the scion: select the strong, lignified branches of young buds in the good mother tree without damage by diseases and insect pests as the scion;

[0031] S3. Broken anvil: Select 4-28 side branches near the crown of the rootstock as grafted rootstock branches, saw off each side branch, keep the length of the branch at about 20 cm, then cut off the main trunk at the top, and organize the broken anvil smooth;

[0032] S4. Cutting the anvil: Use a grafting knife to cut off the edge of the interface of the anvil, so that the interface forms a small slope, and then use the tip of the knife to draw a vertical line above the bark on the small s...

Embodiment 2

[0047] A dwarf and high-yield grafting technique for star anise, comprising the following steps:

[0048] S1, select rootstock: select well-developed root system, strong resistance, no damage by diseases and insect pests and a height of 20 centimeters from the ground, a rootstock with a root diameter of 1.1 centimeters;

[0049] S2, collect the scion: select the strong, lignified branches of young buds in the good mother tree without damage by diseases and insect pests as the scion;

[0050]S3. Broken anvil: Select 4-28 side branches near the crown of the rootstock as grafted rootstock branches, saw off each side branch, keep the length of the branch at about 25 cm, then cut off the main trunk at the top, and organize the broken anvil smooth;

[0051] S4. Cutting the anvil: Use a grafting knife to cut off the edge of the interface of the anvil, so that the interface forms a small slope, and then use the tip of the knife to draw a vertical line above the bark on the small slop...

Embodiment 3

[0060] A dwarf and high-yield grafting technique for star anise, comprising the following steps:

[0061] S1, select rootstock: select well-developed root system, strong resistance, no damage by diseases and insect pests and a height of 30 centimeters from the ground, a rootstock with a root diameter of 1.5 centimeters;

[0062] S2, collect the scion: select the strong, lignified branches of young buds in the good mother tree without damage by diseases and insect pests as the scion;

[0063] S3. Broken anvil: Select 4-28 side branches near the crown of the rootstock as grafted rootstock branches, saw off each side branch, keep the length of the branch at about 30 cm, then cut off the main trunk at the top, and arrange the broken anvil smooth;

[0064] S4. Cutting the anvil: Use a grafting knife to cut off the edge of the interface of the anvil, so that the interface forms a small slope, and then use the tip of the knife to draw a vertical line above the bark on the small slop...

Abstract

The invention discloses an anise dwarfing and high-yield grafting technology which comprises the following steps: S1, selecting a rootstock, namely selecting the rootstock which is developed in root system, high in resistance, free of plant diseases and insect pests, 10-40cm above the ground and 0.5-2cm in root diameter; s2, collecting scions: selecting thick, strong and bud lignified branches growing on the upper part of an excellent seed tree without plant diseases and insect pests as the scions; according to dwarfing grafting, the tree height of the star anise tree can be relatively low, fruits can be picked more easily, great convenience is provided for picking personnel, the height of the star anise tree is controlled to be about 5 m, branches are reasonably distributed, light receiving of the star anise tree is facilitated, a good foundation is laid for high yield of the star anise tree, and the method is suitable for large-scale popularization and application. The dwarfing survival rate of the star anise tree obtained through the grafting technology is relatively high, the star anise tree can blossom and bear fruits in the second year after dwarfing, two mature periods exist in one year, two fruits can bear, the yield is far higher than that of the star anise tree which is not dwarfed, and the yield of the dwarfed star anise tree which grows well is about 5 times that of the normal star anise tree.

Description

technical field [0001] The invention relates to the technical field of star anise grafting, in particular to a dwarf and high-yield grafting technology of star anise. Background technique [0002] Star anise is an evergreen arbor broad-leaved tree belonging to the family Octagonaceae, with a tree height of up to 20m. It is a spice and medicinal tree species with fast growth, long life and high economic value unique to the southern subtropical region of my country. Star anise is commonly known as "aniseed" in northern my country. In addition to being used as a condiment, it can also be used as an important raw material for daily chemical products such as perfume, toothpaste, soap, and cosmetics. The effect. Star anise fruit contains about 10% shikimic acid, which is an important raw material for the production of anti-influenza drugs. At present, the area of ​​my country's star anise forest is about 400,000 hm2, of which Guangxi's star anise area and output both account for ...
