Abstract

The invention relates to a breeding method for clone improved dragon well tea 43 in Jiaodong areas. The breeding method is characterized by comprising technological processes of nursery garden selection and settling, spike shearing, cutting, scaffold erecting and shading, nursery management, seeding lifting and the like. The breeding method solves the problems that dragon well green tea 43 seedlings cannot be adapted to boreal climate, the survival rate is low, the management difficult is high, and the like after being introduced form south to Jiaodong areas; and the breeding method is applicable to breeding and cultivation of the dragon well green tea 43 in Jiaodong areas.

Description

Clone tealeaves breeding Dragon Well tea 43 is in the mating system of Jiaodong Areas

Technical field

The present invention relates to tea tree and breed the field, Dragon Well tea 43 green tea are in the mating system of Jiaodong Areas specifically.

Background technology

Longjing green tea originates in Zhejiang, it is a kind of and rare tea tree breed, its mating system is the clone cutting propagation, because southern rainwater evenly causes the tea shoot root system undeveloped, introduce a fine variety Dragon Well tea 43 green tea seedlings from Zhejiang after Jiaodong Areas, can't adapt to boreal climate, survival rate is low, and management difficulty is high.

Summary of the invention

The present invention is for solving Dragon Well tea 43 green tea tea shoots after Jiaodong Areas is introduced a fine variety in south, the tea shoot root system is undeveloped, can't adapt to boreal climate, the problem such as survival rate is low, management difficulty is high provides the method for a kind of Dragon Well tea 43 green tea at Jiaodong Areas clone cutting propagation.

The present invention is for solving the problems of the technologies described above, and the technical scheme of taking is, the mating system of Jiaodong Areas Dragon Well tea 43 green tea, and its special character is to comprise following technical process:

1, nursery lot is selected and arrangement

Nursery lot is chosen in and has a good transport service, physical features is smooth, easily farmland of enough water sources, draining is arranged.That soil property requires is loose, slightly acidic chiltern or light cement earth.Nursery lot is ploughed deeply comprehensively, meticulous bedding, every mu of fertilizer 80-100 kilogram of using the content of organic matter＞70%, join and execute 15 kilograms of superphosphate, fertilizer will be mixed thoroughly with seedbed soil, then spreads the loose soil of 5-6 cm thick in the seedbed, slightly suppression after the shop is even, usefulness during in order to cuttage is then by 8-12 centimetre of wide paddling.

2, cut fringe

From the green tea elite stand select bud tip robust growth, internode is long, branch is sturdy, semi-lignified, cut without the branch of damage by disease and insect, the branch after cutting is placed on shady and cool moist place, in case dehydration is too much.The spike length of clip is 2-4 centimetre, has 1 full axillalry bud and 1 sound true leaf on each fringe, and clip must be level and smooth, clip oblique with leaf to consistent.

3, cuttage

Cut fringe the same day, cuttage on the same day.Cuttage is before at 10 o'clock in the morning or carry out when sunlight turns weak afternoon.It is moistening fully to be sprayed water in the seedbed first before the cuttage, plugged ear is put into root-growing agent solution soak 2-4 second, when treating that earth is tack-free, by line-spacing 8-12 centimetre with plugged ear during live or oblique cutting buries, the degree of depth is advisable to expose petiole, the blade Chaoyang, and the limit insert edge is with a little compacting of soil.Spacing in the rows optic lobe sheet width and deciding does not hide blade to be stacked as suitable mutually.About 130,000 pieces of every mu of nursery cuttages.Fully water immediately after the cuttage.

4, scaffolding shades

Build immediately shading shed after the cuttage, the high 40-50 of canopy centimetre, adopt sunshade net to cover, to avoid the daylight acute irradiation, reduce the ground wind speed, reduce the moisture evaporation, be beneficial to and improve cuttage survival rate and growth of seedling.

5, nursery bed management

Water.Plugged ear wants duty to water before root of hair not, to keep ground moistening, increases air humidity.Fine morning, evening respectively water once, and one day cloudy day watered once, and the rainy day can not water, and should note draining behind the heavy rain.Behind the plugged ear root of hair, every other day or watered water in several days one time, keep ground moistening to get final product.

The shading shed management.Shading shed is wanted timely maintenance and inspection, should increase the shading shed light transmittance behind the plugged ear root of hair.Relatively poor because of Dragon Well tea 43 green tea cold hardinesses, add a cover film when should arriving in the winter time to strengthen ground temperature, removed when next year, temperature went up.

In time weeding, except bud.Weeds on the seedbed will in time remove with hand-lifting, and the bud of tea shoot will in time be extractd with hand.

In good time fertilising.Though seedling can be from soil the absorption portion nutrient, because Primary Root System is few, need to impose in right amount fertilizer.Fertilising should be grasped by stages repeatedly.When the plugged ear root reaches 3-4 centimetre when forming the first repayment group, beginning is fertilising for the first time, per month 1 time later on.Fertilizer is with rare light being advisable, and general combination applies when watering.

Short root.When tea shoot grows 3-4 layer bud-leaf, reduce the frequency of pouring underground water, underground water of interval pouring in 15 days.Change into during this time and spray blade face water and keep tea shoot life.

The anti-worm of curing the disease.Seedling stage, common sick worm had smaller green leaf hopper, tea aphid and leaf disease etc., in time spraying insecticide or bactericide.The spray medicine should spray after the level of blade face after watering.

6, lifting

The green tea seedling of cuttage is in lifting plantation in one October of September in next year.

Technique effect

Technique effect of the present invention is, adopt above-mentioned technical scheme, can realize that Dragon Well tea 43 green tea breed, cultivate at Jiaodong Areas, the tea shoot well developed root system of bred, 1 year the longest 22cm that reaches of seedling, resistance against diseases is strong, and survival rate is high, management is simple, has solved undeveloped, the problem such as management difficulty large low in the north survival rate of southern tea shoot root system.

Embodiment

1, nursery lot is selected and arrangement

Have a good transport service, physical features is smooth, enough water sources are arranged, draining convenient, the soil is porous, the farmland of subacidity chiltern or light cement earth selects 1 square metre of area to make nursery lot, plough deeply, meticulous bedding, use the fertilizer 0.12-0.15 kilogram of the content of organic matter＞70%, join and execute 0.02 kilogram of superphosphate, fertilizer and seedbed soil are mixed thoroughly, then spread the loose soil of 5-6 cm thick in the seedbed, slightly suppression after the shop is even, usefulness during in order to cuttage is then by 8-12 centimetre of wide paddling.
