Embodiment 1

[0029] A grafting method for improving the survival rate of red rocket crape myrtle seedlings, comprising the following steps:

[0030] S1: Rootstock selection and treatment: choose a 10-year-old local fast-growing crape myrtle pile in Wuming District, Nanning City, with a thick and straight trunk, no pests and diseases, and no damage as a rootstock, saw it to a height of 0.8, and flatten the wounded surface. The two relative positions on the edge of the section are cut obliquely downward, exposing the cambium I, and spraying the nutrient solution;

[0031] S2: scion selection and treatment: choose 7-year-old red rocket crape myrtle 8 cm seedlings without pests and diseases and no damage as scions, and the buds in the middle of the branches are full and plump as buds; soak in nutrient solution for 4 hours before grafting;

[0032] S3: Grafting: Using the cutting method, cut obliquely downward on the wounded surface of the scion to form cambium II corresponding to cambium I, in...

Embodiment 2

[0035] A grafting method for improving the survival rate of red rocket crape myrtle seedlings, comprising the following steps:

[0036] S1: Rootstock selection and treatment: choose a 15-year-old local fast-growing crape myrtle pile in Wuming District, Nanning City, with a thick and straight trunk, no pests and diseases, and no damage as a rootstock. The two relative positions on the edge of the section are cut obliquely downward, exposing the cambium I, and spraying the nutrient solution;

[0037] S2: scion selection and treatment: choose 9-year-old red rocket crape myrtle 5 cm seedlings without pests and diseases and no damage as scions, and the buds in the middle of the branches are full and plump as buds; soak in nutrient solution for 5 hours before grafting;

[0038] S3: Grafting: Using the cutting method, cut obliquely downward on the scion wound surface to form cambium II corresponding to cambium I, insert cambium II into cambium I and tie it tightly, and control the te...

Embodiment 3

[0041] A grafting method for improving the survival rate of red rocket crape myrtle seedlings, comprising the following steps:

[0042]S1: Rootstock selection and treatment: choose a 25-year-old local fast-growing crape myrtle pile in Wuming District, Nanning City, with a thick and straight trunk, no pests and diseases, and no damage as a rootstock, saw it to a height of 1.2m, and flatten the wounded surface The two opposite positions on the edge of the section are cut downwards, exposing the cambium I, and spraying the nutrient solution;

[0043] S2: scion selection and treatment: select 6-year-old red rocket crape myrtle 6 cm seedlings without pests and diseases and no damage as the scion, and the full and full buds in the middle of the branches are used as the graft; soak in nutrient solution for 3 hours before grafting;

[0044] S3: Grafting: Using the cutting method, cut obliquely downward on the wounded surface of the scion to form cambium II corresponding to cambium I, ...

Abstract

The invention discloses a grafting method for improving the survival rate of red rocket lagerstroemia nursery stocks, which comprises the following steps: S1, stock selection and treatment: selecting a local fast-growing lagerstroemia old stump with a thick and straight trunk, no pest and disease damage and no damage as a stock, sawing off the stock, flattening the damaged surface, making a cambium I, and spraying a nutrient solution; s2, scion selection and treatment: selecting a red rocket lagerstroemia indica adult seedling free of plant diseases and insect pests and damage as a scion, and soaking the scion in a nutrient solution before grafting; s3, grafting, wherein a forming layer II corresponding to the forming layer I is manufactured on the scion wound surface, and the forming layer II and the forming layer I are close to each other and tightened; the temperature in the whole grafting process is controlled to be 17-20 DEG C, and the humidity is controlled to be 50-60%; and unbinding after the grafted buds grow to 15-20 cm. The method can improve the grafting survival rate of the lagerstroemia indica seedlings, accelerate the growth speed and improve the quality of the lagerstroemia indica seedlings.

Description

technical field [0001] The invention belongs to the technical field of red rocket crape myrtle cultivation, and in particular relates to a grafting method for improving the survival rate of red rocket crape myrtle seedlings. Background technique [0002] Red rocket crape myrtle (scientific name: Lagerstroemia indica Red Rocket), a deciduous tree of the genus Lagerstroemia indica, a new variety of American red crape myrtle. The flower color of red rocket crape myrtle is bright red and eye-catching. The flowering period is as long as 130 days. It blooms in the same year, which can greatly shorten the seedling time of large-scale seedlings And the quality of seedlings can quickly achieve the effect of greening and beautifying, which meets the requirements for plants in the current urban greening. Red rocket crape myrtle is one of the most bright red varieties of crape myrtle. The flowers are as bright red as a red flag. The flower clusters can reach 24 inches. The flowers are ...
