Embodiment 1

[0019] A kind of grafting method of crape myrtle, comprises the following steps:

[0020] 1) Selection of rootstocks: select American red rocket crape myrtle from November to February of the next year, leave the trunk at a height of 115 cm when planting, and cut off the upper part; after the new spring shoots grow, select 3 with suitable angles The main branch, the diameter of the main branch is 2.5cm; the upper end side of the main branch is longitudinally cut 15 degrees inward, spraying the nutrient solution to the incision of the main branch, and covering the incision after spraying with a film for 15 hours;

[0021] 2) Selection of the scion: Before the scion germinates in the spring, choose a red fireball crape myrtle branch with a diameter of 2 cm, and select at least 4 buds on the scion; cut off the buds at the lower part of the scion; Cut a 3 cm long bevel on the straight side of the lower part; cut a horse ear-shaped bevel on the back of the long bevel, and form a 45-...

Embodiment 2

[0025] A kind of grafting method of crape myrtle, comprises the following steps:

[0026] 1) Selection of rootstocks: select American red rocket crape myrtle from November to February of the next year, leave the trunk 120 cm high when planting, and cut off the upper part; after the new spring shoots grow, select 4 with suitable angles The main branch, the diameter of the main branch is 3.2cm; the upper end side of the main branch is longitudinally cut 18 degrees inward, spraying nutrient solution to the incision of the main branch, and covering the incision after spraying with film for 18 hours;

[0027] 2) Selection of the scion: Before the scion germinates in the spring, choose a red fireball crape myrtle branch with a diameter of 3 cm, and select at least 5 buds on the scion; cut off the buds at the lower part of the scion; The straight side of the lower part cuts a long bevel with a length of 2.8 cm; the second cut cuts a horse-ear-shaped bevel on the back of the long beve...

Embodiment 3

[0031] A kind of grafting method of crape myrtle, comprises the following steps:

[0032] 1) Selection of rootstocks: select the American red rocket crape myrtle from November to February of the next year, leave the trunk at a height of 125 cm when planting, and cut off the upper part; after the new spring shoots grow, select 3-3~ 4 main branches, the diameter of the main branch is 4cm; the upper end side of the main branch is longitudinally cut 20 degrees inward, spraying nutrient solution to the incision of the main branch, and covering the incision after spraying with film for 20 hours;

[0033] 2) Selection of the scion: before the scion germinates in the spring, choose a red fireball crape myrtle branch with a diameter of 4cm, and select at least 4 buds on the scion; cut off the buds at the bottom of the scion; Cut a 3.2 cm long bevel on the straight side of the lower part; cut a horse ear-shaped bevel on the back of the long bevel, and form a 45-degree angle with the lon...

Abstract

The invention provides a lagerstroemia-indica grafting method. The lagerstroemia-indica grafting method includes the following steps of 1) stock selecting, wherein American lagerstroemia indica red rockets growing from leaf falling in November to February in the next year are selected, the height of trunks remains 115 cm to 125 cm during transplanting, the upper portions are cut off, and a nutrient solution is sprayed to notches of main branches; 2) scion selecting, wherein scions are selected before sprouting in spring, lagerstroemia indica dynamite branches with the diameter of 1.5 cm to 4 cm are selected, scions with at least 4-5 of bud scions are selected, buds at the lower portions of scion branches are chipped off, the chipped-off scions immerge into a nutrient solution, and the nutrient solution is fully absorbed by the scions; 3) grafting, wherein in summer and the weather is that the sun shines again after rain, the scions treated by the nutrient solution in the step 2) are inserted into the stock notches treated by the nutrient solution in the step 1), close attachment is carried out, and the outer sides of the upper portions and the lower portions of the combination portions between the bud scions and the stocks are tightened with films. According to the lagerstroemia-indica grafting method, the American lagerstroemia indica red rocket serves as the stock, lagerstroemia indica dynamite serves as the scion, and the grafting survival rate is high.
