Embodiment 1

[0022] Seedbed disinfection and construction: the seedbed is 1.2m wide, and 25 days before cutting, plow the tea garden soil to a depth of about 20cm, and use 5% mixture of thiophanate-methyl and carbofuran (the mass ratio of thiophanate-methyl to carbofuran is 1:3) Spray the plowed soil surface; water the river sand soil with 0.3% potassium permanganate solution. 7 days before cutting, spread the river sand on the tea garden soil, stir the tea garden soil and river sand to mix them, the volume ratio of river sand and tea garden soil is 2:3; then rinse with clean water until the seedbed seeps out until. Then build a small arch shed on the seedbed with a height of 0.6-0.8m.

[0023] Collection of cuttings: Collect old branches of tea trees with a stem thickness of 1-2cm and a length of 15-35cm in October as cuttings. And the base was sterilized in 70% thiophanate-methyl 1000 times solution for 2 minutes, and the solution was submerged 1 cm deep into the base incision.

Embodiment 2

[0030] Seedbed disinfection and construction: the seedbed is 1.2m wide, and 25 days before cutting, plow the tea garden soil to a depth of about 20cm. 1:3) Spray the plowed soil surface; water the river sand soil with 0.3% potassium permanganate solution. 7 days before cutting, spread the river sand on the tea garden soil, stir the tea garden soil and river sand to mix them, the volume ratio of river sand and tea garden soil is 1:1; then rinse with clean water until the seedbed seeps out until. Then build a small arch shed on the seedbed with a height of 0.6-0.8m.

[0031] Collection of cuttings: In August, collect old branches of tea trees with a thickness of 1-2cm and a length of 15-35cm as cuttings. Sterilize in 70% thiophanate-methyl 1000 times solution for 2 minutes, and the solution is submerged 1 cm deep into the base incision.

[0032] Cutting treatment: The cuttings should be soaked in ABT solution within 6 hours of leaving the mother branch. The cuttings should be...

Abstract

The invention provides a cutting propagation method for tea tree old branches. The method comprises the following steps: cutting base parts of cutting slips into 45-degree inclined diagonal planes by taking the tea tree old branches with the stem thickness of 1-2cm and the length of 15-35cm as cutting slips; disinfecting by using 70% thiophanate methyl 1000-time liquid; immersing by using ABT solutions with the concentrations from low to high before cutting; after cutting, keeping the overshadow degree for 75-85%; and spraying the disinfecting liquid to keep soil humidity until roots grow. The tea tree old branches which are survived by cutting are transported to pots and are pruned and coiled to be molded into a tea tree potted landscape. The method is short in period, rapid in molding, low in production cost and simple to operate. The problem that the tea tree old branches are difficult to survive by cutting is solved; bred new plants have thick stem and are old; a molded mini-type potted landscape can be rapidly manufactured and the ideal modeling effect of simple and unsophisticated and powerful advantages is realized.

Description

technical field [0001] The invention belongs to the technical field of plant asexual propagation, and in particular relates to a method for cutting and propagating old branches of tea trees. Background technique [0002] At present, tea tree propagation is mainly propagated by cuttings, layering, and grafting. Most of the traditional cutting methods use the semi-lignified branches of the year, the length is about 3-5cm, and the branches with 1 bud and 1 leaf or 2 leaves are used as cuttings. The new plants propagated are used as seedlings for tea tree planting, but if they are used to make bonsai, they are not old enough to achieve the desired effect. [0003] Such as Chinese patent application number is 201110405357.4 " a kind of tea tree hard branch cutting seedling raising method ", is to select the first half of the year tea tree hard branch to cut into 4-5cm in March, stay 1-2 bud, half leaf to a whole leaf as cuttings. Soak the base of the cuttings in 20ppm naphthale...
