Abstract

The invention belongs to the technical field of tea plant seedling raising, and particularly relates to a hardwood cutting seedling raising method for a tea plant. In the method, the technical measures of parental garden cultivation, matrix cutting, shading and seedling raising of a seedling management system are adopted by taking tea plant hardwoods as cuttings; and the method shows the capabilities of saving labor, saving water and reducing cost and a rapid seedling raising effect of cultivating strong tea seedlings in the current year.

Description

A kind of tea tree hardwood cutting and seedling raising method

 

One, technical field

This invention belongs to tea tree seedling growing process field, is specifically related to a kind of tea tree cuttage and system management technologies utilized, the method for cultivating healthy and strong tea shoot.

Two, background technology

The tea tree cuttage seedling raising method is a kind of mating system that generally adopts on the Tea Production; Be the branch that adopts growth of tea plant then in the actual production as inserting fringe, but six after promptly spring tea is finished, July clip branch cutting just could be cultivated new branch after last year, branch need cut off; Inserting fringe passes through in new native nursery cuttage, shades, manages out the garden; It is convenient that this traditional cottage method is got fringe, and technology is prone to grasp, and weak point is: wasted branch last year; Maternal tea place does not have spring tea and can adopt slotting then fringe weak point in vegetative period.The tea tree cuttage is analyzed feasible theoretically, and technology is difficult, does not still have complete cuttage and seedling culture method at present.

Three, summary of the invention

The problem that the present invention need solve is:

Hardwood cutting and seedling raising method promptly utilizes and gives birth to the method that the slotting fringe of branch conduct carries out cuttage and seedling culture last year, through cultivating branch, inserting a kind of new cuttage and seedling culture method of series of measures such as fringe clip, matrix cuttage, coverage shading, fertilising.

Technical scheme of the present invention is:

(1) cultivation and the clip of the hard branch of tea tree: select healthy and strong maternal tea place, prune the science tea garden management behind the spring tea deeply; When spring next year, tea shoot sprouted, the clip branch was divided into the three sections separately cuttages in upper, middle and lower; Help management, short spike length degree, clip direction, stay clip on request such as leaf.

(2) selection of cutting medium and water and fertilizer management: select for use the peat composed of rotten mosses, vermiculite, perlite material as matrix; And mix by the volume proportion of 1:1:1; Keep certain humidity, temperature and illumination; Gradually increase sealing fertilizer after 3 months, the aqueous solution that is made into concentration and is 0.1-0.5% sprays, and guarantees to insert that fringe becomes to live and tea shoot is healthy and strong.

The present invention compared with prior art beneficial effect is:

The present invention has overcome the deficiency of traditional tea tree cuttage and seedling culture, has made full use of tea tree branch resource, has overcome the technological difficulties of tea tree cuttage; Low, the branch of temperature in early spring is old, difficult to be become to live etc., through technique improvement, adopts new technologies such as matrix cuttage, coverage shading, fertilising; Not only cuttage survival rate reaches more than 80%, prolongs owing to insert the fringe growth time, can cultivate healthy and strong tea shoot then; And spring tea can also be plucked in maternal tea place, has improved the spring tea economic benefit.

Four, embodiment:

(1) maternal plant garden is cultivated, late May, prune deeply, and mu sealing fertilizer 100-150 kilogram, mid-October, mu was executed cake fertilizer 250-300 kilogram, cultivated healthy and strong branch;

(2) selection and the clip of slotting fringe are selected the hard branch of tea tree last year March next year, are cut into 4-5 centimetre short fringe; Clip is smoothly parallel, inclined-plane 45 degree, and the clip direction is consistent with direction blade; Insert the fringe upper end and stay leaf, the leaflet kind is stayed a leaf, and the middle period kind is stayed half leaf; Slotting fringe stays 1-2 axillalry bud, stays leaf base and epimere clip 4-5 millimeter;

(3) insert fringe and handle, some slotting fringes are concentrated tie, base portion is immersed in the naphthalene acid solution of 20PPm concentration, taking-up cuttage in 30 minutes with a branch of bundle of rubber band;

(4) prepare in matrix and seedbed, uses the peat composed of rotten mosses: vermiculite: perlite=1:1:1 volume ratio mixes the back as cutting medium, and the seedbed is wide 80 centimetres, and length is looked landform and decided, and 50 meters with interior suitable;

(5) cottage method, 10 centimetres of line-spacings are pressed in the moistening and sterilization with furrow face matrix earlier then before inserting; 4 centimetres of spacing in the rows, the cuttage degree of depth are 2-3 centimetre, and blade is inserted neat towards a direction; Not overlapping between the blade; Blade and ground angle 45 degree compress base portion soil gently, and slotting fringe is closely contacted with soil;

(6) coverage shading is barricaded as little shed with black plastic film and covers, and reduces water evaporates, keeps humidity, on plastic greenhouse, adds a cover the sunshade net summer in good time, regularly ventilates;

(7) seedling management mainly is the adjusting management of moisture, temperature, photoenvironment, and 7-9 month increase sprays 0.1-0.5% aqueous solution composite fertilizer, is beneficial to the formation in strong sprout;

(8) tea shoot goes out the garden, and December 80%, tea shoot was up to more than 25 centimetres then, goes out the garden and transplants.

Claims (1)

1. a tea tree hardwood cutting and seedling raising method is characterized in that adopting the hard branch of tea tree to carry out cuttage as inserting fringe, specifically is made up of following steps:
