Abstract
The invention discloses a method for promoting rooting of tea tree cutting seedlings. The method comprises scion collection, scion sterilization treatment, cutting and nursery bed management, and specifically comprises the steps of immersing branches for cutting in mixed solution of potassium permanganate and boric acid for 3 to 5 hours, then immersing the branches for cutting in mixed solution of ABT rooting powder and carbendazim for 2 to 8 hours, and performing cutting and later-stage nursery bed management. The method for promoting rooting of tea tree cutting seedlings can supplement vitamins and convert embryonic cells into growth-supporting meristem nutrients needed by root cell division; the vitamins can promote the division, growth and the like of plant vascular bundles and facilitate the rooting and germination of the cutting seedlings, the cost in cutting seedling rooting is low by adopting the method, the survival rate of the cutting seedlings is greatly improved and the law that Lingyun Baekho tea is difficult to survive through cutting is broken.
Description
Technical field
The invention belongs to field of plant growing technology, be specifically related to a kind of method promoting Ling Yaoxing tea cutting seedling rooting.
Background technology
Pekoe tea is in the cultivation history of existing more than 300 year of reaching the clouds, and Ling Yaoxing tree product kind sexual propagation system body kind, belongs to dungarunga type and great Ye class, middle non-hibernating eggs.Plant is tall and big, tea tree footpath is thick, and bud-leaf is stout and strong, the food value of leaf is soft, it is long and close to hold strong, the fine and soft milli of tender property, has natural faint scent, includes Tea Polyphenols and the composition such as amino acid, pectin is very abundant, and the self-sow height of tree reaches 6 ~ 9 meters, tree performance partly opens, branch is rarer.Blade horizontal or sagging raw, leaf is large and oval, leaf look viridescent comparatively clouding, blade face protuberance, blade back crinosity, vein close aobvious, the food value of leaf is thin soft.
Because pekoe tea kind belongs to colony of sexual system kind, tea tree is again cross pollinated plant, and locality is all with seed sowing all the time, the Ling Yaoxing single variety of plantation.Again because Ling Yaoxing vein is close aobvious, the food value of leaf is thin soft, seedling resistance is more weak, the mode of cutting seedling plantation, and use management way is the method for other teas, can only ensure that his moisture content is sufficient, cutting seedling only stays leaf, and the energy transformed by photosynthesis is extremely few, can not supply the nutrient component needed for seedlings plugging growth in time, cause Ling Yaoxing germinate evening, yield poorly, resistance is poor, cuttage survival rate is low.
ABT root-inducing powder is a kind of efficient, wide spectrum, composite plant growth regulator, he is to the propagation of plant cell, differentiation, ABT root-inducing powder is used to play a role to the generation of cuttage shoot root and elongation, but the cuttage seeding clip cut with scissors is easily infected, ABT root-inducing powder does not prevent infection of incisional wound bacterial action, and Ling Yaoxing is the kind being difficult to cuttage, use the cottage method survival rate of other teas extremely low, this has become a great problem that restriction Ling Yaoxing expands plantation.
Summary of the invention
The object of the invention is to solve Ling Yaoxing cuttage seeding otch and be subject to bacteriological infection, problem that cuttage seeding survival rate is low, provide a kind of method promoting Ling Yaoxing tea cutting seedling rooting, the technical scheme used for realizing the object of the invention is:
Promote a method for tea cutting seedling rooting, comprise the collection of fringe bar, the sterilization treatment of cuttings, cuttage and nursery bed management, concrete steps are as follows:
(1) fringe bar gathers: from stock tree gather axillalry bud is full, blade is complete lignification or half a lifetime the lignified spring tip, summer shoot or autumn growth branch make cuttings;
(2) sterilization treatment of cuttings: after the collection of cuttings branch being returned, soaks 3-5 hour with potassium permanganate and boric acid mixed solution, and in described potassium permanganate and boric acid mixed solution, the ratio of water, potassium permanganate and boric acid is 5000:1:3; Again cuttings branch is cut into cuttage brachyplast, soaks 2-8 hour with ABT root-inducing powder and carbendazim mixed solution, in described ABT root-inducing powder and carbendazim mixed solution, the ratio of ABT root-inducing powder, water and carbendazim is 1:100:15;
(3) cuttage: is fully sprinkled water in seedbed, ensure that the moisture content of soil is 40-60%, the temperature of soil is 28-35 DEG C, and by cuttings with line-spacing 8-10cm, spacing in the rows is during the cutting density straight cutting of 2-3cm or oblique cutting bury, then compacting soil;
(4) nursery bed management: 1. irrigate, all will note irrigating in whole seedling stage; Principle is: high temperature waters more, and low temperature waters less, waters more, water less after root of hair before root of hair; First month under particularly inserting, spray water every day 3 times, the rainy day does not water, cloudy day water spray 1 time, and before root of hair, adopt watering can watering, spill evenly, water will clean;
2. cuttage same day, spray thiophanate methyl liquid after spray water in 1-3 hour and carry out sterilization, described thiophanate methyl liquid is 500-700 times of liquid;
3. vitamin, carbendazim, La-methyl α-naphthyl acetate, chlorophyll mixed solution are used in cuttage after one week; Described vitamin: carbendazim: La-methyl α-naphthyl acetate: chlorophyll: thiophanate methyl: the ratio of water is 5:10:1:10:20:22000, sprays weekly once afterwards, till cuttage seeding roots.
Preferably, in the sterilization process steps of described cuttings, after the collection of cuttings branch is returned, after soaking 4 hours with potassium permanganate and boric acid mixed solution, then after cuttings branch is cut into cuttage brachyplast, soak 3-5 hour with ABT root-inducing powder and carbendazim mixed solution.
Preferably, in described cuttage step, the water content in seedbed is 40-50%, and the temperature of soil is 28-32 DEG C.
Preferably, described thiophanate methyl liquid is 600 times of liquid.
Preferably, described vitamin is vitamin B1, B6, B12.
The substantive distinguishing features that the present invention gives prominence to and significant progress are:
Cuttings branch of the present invention first uses potassium permanganate and boric acid mixed solution to carry out disinfection, potassium permanganate is a kind of strong oxidizer, there is very strong virus killing, disappear bacterium effect, especially sick to the column in seedling stage, fusarium wilt, soft rot, the control of the diseases such as root rot has good effect, and boric acid is a kind of trace element fertilizer, prevent plant wasting disease from playing a role, good control efficiency is had to cuttage seeding base portion, first carry out sterilizing process to him, prevent the virus infections being subject to plant itself at cuttage mouth, re-use ABT root-inducing powder and carbendazim mixed solution is killed virus to otch, to many sac fungis, imperfect fungus and various basidiomycetes, head blight, anthracnose, scabs etc. have generation and the elongation of good preventing effectiveness and promotion cuttage shoot root.
Replenishing vitamins of the present invention changes the growth encourage mitogenetic nutrient of blastocyte needed for foundation cell division; Vitamin promotes the merisis etc. of plant vasular bundle, is conducive to cuttage seeding and roots, and the cost that the method cuttage seeding is taken root is low, the survival rate that greatly improves cuttage seeding, breaks the law that Ling Yaoxing cuttage difficulty survives.
