Problems solved by technology

Among them, tissue culture requires high technology, complicated operation, and high production cost; grafting propagation requires a large amount of labor, and rootstocks for more than two years must be cultivated, while cutting propagation has simple conditions, easy operation, and low propagation cost.
[0004] At present, the Lagerstroemia crape myrtle cutting seedling raising technology in the prior art has the advantages of simple conditions, easy operation, and low propagation cost, but there are still some problems, such as the average root length and unsatisfactory survival rate, etc.

Embodiment 1

[0024] (1) Cutting substrate selection: use fine river sand as the cutting substrate, with a diameter of 0.35-0.25mm, use 58% metalaxyl-manganese zinc wettable powder 1000 times solution after disinfection, and lay the fine river sand on the seedbed with a thickness of 25cm;

[0025] (2) Selection of cuttings: In the middle and late June, semi-lignified branches that are healthy and free from diseases and insect pests are selected as cuttings. The cuttings are selected with 2 buds, the length of the cuttings is 6cm, and the strong branches of the cutting section are 3mm. The base is cut into a smooth slope. Use 1000mg / L naphthalene acetic acid solution (NAA) to quickly dip the cuttings;

[0026] (3) Cutting: the cutting density is 620 plants / m 2 , the cutting depth is two-thirds of the total length of the branches, spray carbendazim 600 times after cutting;

[0027] (4) Management after cuttings: After cuttings, cover the sunshade net on the greenhouse, and control the temper...

[0030] (1) Cutting substrate selection: use fine river sand as the cutting substrate, with a diameter of 0.35-0.25mm, use 58% metalaxyl-manganese zinc wettable powder 1000 times solution after disinfection, and lay the fine river sand on the seedbed with a thickness of 25cm;

[0031] (2) Selection of cuttings: In the middle and late June, semi-lignified branches that are strong and free of diseases and insect pests are selected as cuttings. The cuttings are selected with 3 buds, the length of the cuttings is 8cm, and the strong branches of the cutting section are 5mm. The base is cut into a smooth slope. Use 2000mg / L naphthalene acetic acid solution (NAA) to quickly dip the cuttings;

[0032] (3) Cutting: the cutting density is 700 plants / m 2 , The cutting depth is two-thirds of the total length of the branches, and the cuttings are sprayed with 600 times of carbendazim. ;

[0033] (4) Management after cuttings: After cuttings, cover the sunshade net on the greenhouse, and c...

[0036] (1) Cutting substrate selection: use fine river sand as the cutting substrate, with a diameter of 0.35-0.25mm, use 58% metalaxyl-manganese zinc wettable powder 1000 times solution after disinfection, and lay the fine river sand on the seedbed with a thickness of 25cm;

[0037] (2) Selection of cuttings: In the middle and late June, semi-lignified branches that are healthy and free from diseases and insect pests are selected as cuttings. The cuttings are selected with 2 buds, the length of the cuttings is 7cm, and the strong branches of the cutting section are 4mm. The base is cut into a smooth slope. Use 1500mg / L naphthalene acetic acid solution (NAA) to quickly dip the cuttings;

[0038] (3) Cutting: the cutting density is 660 plants / m 2 , The cutting depth is two-thirds of the total length of the branches, and the cuttings are sprayed with 600 times of carbendazim. ;

Abstract

The invention provides a method for high-density cutting seedling of twigs of Lagerstroemia indica Pink Velour. The method comprises the following steps: (1) selecting cutting medium; (2) selecting cutting slips; (3) cutting; (4) managing after cutting; (5) hardening seedlings and transplanting. Compared with the prior art, the method provided by the invention not only has the advantages of simple condition, easy operation and low reproductive cost in the prior art, but also can increase the average root length of cut lagerstroemia indica obviously and can greatly increase the survival rate of transplanted seedlings.

Description

technical field [0001] The invention relates to a velvet crape myrtle high-density twig cutting seedling raising method, which belongs to the field of tree asexual propagation methods. Background technique [0002] Velvet crape myrtle (Lagerstroemia indica 'Pink Velour') is a deciduous erect small tree with a height of 8-10m and a crown width of 10-12m. Strong upright type (side branches grow upward at an angle of 45 degrees), unique leaf color (new leaves are tender red, old leaves are dark green), noble flower color (rose red flowers), super long flowering period (up to 150-180 days in the south), flowers The volume is extra large (the longest panicle can reach 50cm), the flowers are fragrant (the flowers are fragrant and elegant), the growth is fast (the root system is abnormally developed, and the ground diameter can grow 1.5-2.1cm in Jiangsu every year) and extremely low temperature resistance (can withstand -20℃ low temperature) and so on. Velvet crape myrtle integra...
