Problems solved by technology

[0005] At present, the main breeding method of oleander is cutting propagation. However, during the breeding process, rooting is often difficult and slow, the upper and lower cuts are easily infected by bacteria and rot, and the skin is damaged during the cutting process. The rooting rate of general cuttings of oleander is only about 70%

Embodiment 1

[0028] The oleander cutting propagation method of the present embodiment specifically comprises the following steps

[0029] 1. Select the mother plant for cuttings. The selected mother plant should have good quality, strong growth, no pests and diseases, etc., and it is advisable to be at the age of 3-5. On the same plant, the cuttings generally have shorter internodes, thick branches and leaves, and full buds. On the same branch, the middle and lower branches are generally used for cuttings, and the cuts of the cuttings should be smooth, the upper end should be cut into a horizontal plane, and the lower end should be cut into a slope. When cutting branches, choose thick branches with a diameter of 2 to 2.5 cm, and the length of the cuttings is 10 to 12 cm. The cuttings must have two or three buds. The upper cut is about 1.5 cm away from the buds, and the lower leaves are removed. The best cutting time is in early spring and March, which is the second month of spring in the...

Embodiment 2

[0035] Others are the same as in Example 1, but the cutting method is:

[0036] 4. Cutting method. Perforate holes in the cutting medium of the slotting bed, then take several pieces of cutting medium and glue them to the base of the oleander cuttings, and then insert the cuttings of oleander into the holes, the size of the holes is the same as that of the sticking The size of the cutting medium is matched to the base of the oleander cuttings.

Embodiment 3

[0038] Adopt conventional mode to select the same standard cuttings cuttage with embodiment 1, concrete steps are:

[0039] Facilities and seedbed preparation. Cuttings in greenhouses should be covered with greenhouse films and shade nets. After the ground in the shed is leveled, a ground cutting seedbed is established. The width of the seedbed can be about 100 cm, and 10-12 cm high baffles are installed around it. Spread a layer of fine sand on the bottom of the seedbed to facilitate drainage, and vermiculite can be used as the cutting substrate. Seedbeds and substrates should be disinfected with fungicides and insecticides to prevent pests and diseases.

[0040] In the spring in early March, the length of the cuttings is controlled at 10 cm, and 1-2 healthy leaves are left. Before cutting, the cuttings are treated with rooting agent. The cutting depth is preferably 7 cm, and the row spacing is 5 x 10 cm. Water thoroughly after cutting.

[0041] For post-planting managem...

Abstract

The invention discloses a cutting cultivating method of thevetia peruviana. The method comprises the following steps: (1) applying a naphthylacetic acid solution to 1cm to 2cm of a stem base of each thevetia peruviana cutting strip; (2) perforating holes in a cutting medium of a cutting bed, and inserting the thevetia peruviana cutting strips into the holes; (3) cultivating the cut thevetia peruviana for 30 days under the condition of 20 to 25 DEG C and relative humidity of 80 to 85 percent, and applying carbendazim one time every ten days; the cutting medium in the step (2) is prepared by a following method: taking yellow soil in the depth of 1m, exposing the yellow soil, crushing the yellow soil, mixing the yellow soil with sawdust according to a weight ratio of 6: 4 by continuously watering the mixture to maintain wet, and adding disinfectant and uniformly stirring the disinfectant and the yellow soil.

Description

technical field [0001] The invention relates to a cutting propagation method of oleander oleander, belonging to the field of cultivation methods of oleander oleander. Background technique [0002] Thevetia Peruviana (Thevetia Peruviana), belonging to the genus Apocynaceae, is a tree with a height of 5 meters. The whole plant is glabrous; the bark is brown with obvious pores; the branches are soft and the branchlets are drooping; the whole plant has abundant milk. Leaves alternate, subleathery, sessile, linear or linear-lanceolate. Both ends long and pointed, 10-15 cm long, 5-12 cm wide, bright, entire, slightly dorsally curled; leaf veins are sunken on the leaf surface, raised on the back of the leaf, and the lateral veins are not obvious on both sides. Flowers are large, yellow, fragrant, terminal cymes, 5-9 cm long; pedicels 2-4 cm long; calyx green, 5-lobed, triangular lobes, 5-9 mm long, 1.5-3 mm wide; corolla funnel Shaped, corolla tube throat with 5 hairy scales, co...
