Problems solved by technology

[0003] Chrysanthemum chrysanthemum is a tree species that is difficult to grow seedlings and afforestation by cutting. It is usually used to raise seedlings and afforestation by sowing, but there is a shortcoming of long cycle time for sowing seedlings.
In the prior art, there are also techniques for growing seedlings and afforestation using root cuttings, but root cuttings need to dig out the roots of P.

Embodiment 1

[0046] (1-1) Select cutting substrate and container

[0047] Cutting seedlings are grown in the seedling greenhouse. The cutting substrate ratio is: 40-80 mesh river sand 50wt%, yellow heart soil 30wt% and peat soil 20wt%. Wash; use the non-woven fabric seedling container filled with matrix as the cutting seedling container, specifications: diameter 10cm, height 15cm;

[0048] (1-2) Collect bud strips and cut cuttings

[0049] The cutting test was carried out in the greenhouse in the spring and summer seasons. When the germination strips of P. japonica in the field grew to 30-60cm, the sprouting strips were cut and brought back to the greenhouse for later use; Cut the cuttings into 15-25 cm long cuttings with sharp branch scissors, each cutting has two nodes; the upper end of the incision is cut flat, 2-3 cm away from the upper node, leaving 50% of the leaf surface of the upper node; each The cuttings contain 2-3 branches and leaves, the lower end of the incision is 2-3cm be...

Embodiment 2

[0059] The difference between this embodiment and embodiment 1 is: as figure 2 As shown, in step (1-1), four gas-permeable monitoring tubes 1 are pre-embedded in the cutting matrix, and the gas-permeable monitoring tubes 1 are selected from 2mL round-bottomed plastic centrifuge tubes (specifications: the inner diameter of the nozzle is 9mm, the outer diameter of the nozzle is 13mm, height 42mm): the round bottom of the round bottom plastic centrifuge tube is cut off (cut height 2mm), and the bottle cap is removed; the four ventilating monitoring tubes 1 are distributed equidistantly around the cutting center 2 and are spaced apart from the cutting center. The distance M1 of 2 is 2-3cm; the vertical distance M2 between the bottom of the air-permeable monitoring tube 1 and the bottom of the cuttings 3 is 2-3cm, and the mouth of the air-permeable monitoring tube 1 is 1-2mm higher than the upper surface of the cutting substrate. The air-permeable monitoring tube 1 can monitor whe...

Embodiment 3

[0061] The difference between this embodiment and embodiment 1 is: as image 3 As shown, in step (1-1), after the cutting, forcefully press four matrix-dense conical tubes 4 into the cutting matrix, and the matrix-dense conical tube 4 is a 0.2mL pointed-bottomed plastic centrifuge tube (specification: tube Mouth inner diameter 5mm, tube mouth outer diameter 7mm, height 22mm) make, remove bottle cap; Burn yellow core soil permeation hole 41 on the side wall of described substrate dense tapered tube 4, the aperture of described yellow core soil permeation hole 41 is 1-2mm, The distance between the upper and lower adjacent yellow core soil permeable holes 41 is 0.3-0.5mm, and the distance between the left and right adjacent yellow core soil permeable holes 41 is also 0.3-0.5mm. The matrix dense conical tube 4 is pre-filled with yellow core soil And inject water until water seeps outward from the permeable hole 41 of the yellow core soil; the four dense conical tubes 4 of the matr...

Abstract

The invention relates to a method for cultivating tabebuia chrysantha, which comprises the following steps of: (1) carrying out cuttage seedling cultivation on tabebuia chrysantha: (1-1) selecting a cuttage substrate and a container, (1-2) collecting sprouting strips, shearing and cutting, (1-3) sterilizing and disinfecting ear strips, (1-4) treating the ear strips with rooting hormone, (1-5) carrying out cuttage, (1-6) carrying out seedling hardening management, (2) carrying out field cultivation, fertilizing and nursing management on tabebuia chrysantha, (2-1) selecting tabebuia chrysantha planting lands and carrying out cleaning and ploughing on an afforestation field, (2-2) selecting tabebuia chrysantha planting base fertilizer, (2-3) determining planting density, (2-4) planting seedlings: digging holes, basal dressing and planting, (2-5) carrying out tending management and topdressing, (2-6) clipping plantings, (2-7) controlling plant diseases and insect pests, The cuttage seedling raising technology of the method can effectively improve the survival rate of the tabebuia chrysantha and can achieve the rapid cultivation of the tabebuia chrysantha into a forest.

Description

technical field [0001] The invention relates to the technical field of breeding and cultivation. Specifically, it is a method for cultivating P. japonica. Background technique [0002] Campanula is a deciduous tree belonging to the Bignoniaceae family, with a height of up to 5 meters. Campanula will change its appearance with the changes of the seasons: in spring, the branches and leaves are sparse, and beautiful yellow flowers will bloom around Qingming Festival; in summer Long leaves bear pods; in autumn, the branches and leaves are flourishing, a green scene; in winter, the dead branches and leaves show a desolate beauty. Due to the different and unique styles of the chrysanthemum in spring, summer, autumn and winter, it can be used as a shade tree or street tree in gardens, courtyards, highways, lawns in scenic areas, and ponds, and is suitable for planting alone or side by side. It is an excellent landscaping tree species. [0003] Campanula chrysanthemum is a tree s...
