Embodiment

[0016] Example: A method for raising seedlings by cuttings of tea tree autumn twigs, using the semi-lignified branches of the year around September as cuttings:

[0017] 1. Substrate screening: According to the shortcomings of tea tree cuttings such as long rooting time and slow growth after rooting, vermicompost and perlite are selected as cutting substrates.

[0018] 2. Substrate preparation and treatment: choose vermicompost and perlite as the substrate, the ratio of the two is 1:3~1:5, mix well and set aside.

[0019] 3. Acupoint selection: generally choose a 60 or 72-hole acupoint. After filling the tray with matrix, fully infiltrate it, and compact it properly, and fill it up again;

[0020] 4. Selection of cuttings: Select vigorous growth and no pests and diseases from the female parent garden as cuttings, cut them and insert them into the bucket, and wet them with water.

[0021] 5. Cutting cuttings: Select semi-lignified branches as cuttings, generally about 3 cm l...

Abstract

The invention discloses a cutting seedling cultivating method for a twig of a tea tree. The method comprises following steps: in late August to the middle of September, selecting purple, semi-lignification twig of current year tea tree as shoot for cutting, intercepting for 3-5cm, cutting for one bud and one leaf, the physiological upper end of the shoot for cutting is flat, the lower end is oblique section, and the distance between the section and the leaf or bud is 0.5cm more or less; generally keeping one leaf, the leaf can be cut off for 1 / 3 or 1 / 2 when the leaf is oversize; soaking the cut shoot for cutting in the rooting powder of 800ppm for 2-4h, and inserting the soaked shoot for cutting into the medium comprising earthworm fertilizer with 60 or 72 hole disk and perlite of a ratio of 1: 3-5, generally managing, and transplanting in the spring; the cutting seedling cultivating method for the twig of the tea tree effectively uses the season advantage and earthworm manure lasting characteristic for improving the cutting and rooting efficiency for many varieties of tea tree and effectively shortening breeding and seedling cultivating time for the tee tree seedling; the survival rate of transplanting is high, the cutting medium is simple, the production cost is low, the operation is easy and the managing cost is low.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a method for growing seedlings by cuttings of tea tree twigs. Background technique [0002] At present, tea trees mainly reproduce asexually. Due to different varieties, the rooting rate of tea tree cuttings varies greatly, and the seedling rate is low. Combined with the rooting characteristics of tea trees and the requirements for root system development, this technology uses earthworm fertilizers with high nutritional content and loose and breathable perlite as the substrate for tea tree short branch cuttings, and plug trays are used as cutting containers. Ding Dahao and other varieties have achieved good results, and the seedling rate of cuttings has reached more than 85%. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to overcome the defect of a kind of tea tree variety and a formula, and provide a kind of method suitable for mul...
