Description

A kind of method of tea tree nursery lot covering film in summer sterilization weed eradication

Technical field

A kind of method that the present invention relates to tea cutting nursery lot sterilization, belongs to tea tree asexual grow seedling field.

Background technology

According to textual criticism, tea tree single node cutting technique functions comes from Anxi, 20th century Fujian thirties one band, to the 1950's,The tea tree single-node cutting seed-raising technology that the Fujian Agricultural Room is used with tea grower Anxi, Fujian one is summarized, and by this technologyPromote to the whole nation. Since then, this technology becomes the mainstream technology of Tea Clone stock breeding to be applied so far always, and origin certainlyThrough nearly 80 years, and constantly improve ripe.

Tea tree single-node cutting seed-raising, with fringe few (brachyplast that a leaf band axillalry bud 3-5cm is long), and can keep female wellThis merit (inhereditary material is in full accord), this is the main reason that tea tree single-node cutting seed-raising can be widely used.But tea tree single-node cutting seed-raising, has relatively high expectations to nursery lot, need to do cuttage soil at the thick yellow soil of nursery lot furrow face upper berth 3-5cmLayer. Paving yellow soil is mainly in order to prevent that cuttings from inserting behind seedbed, is subject to microorganism invasion and a key measures taking.Meanwhile, in yellow soil, grass-seed content is low, to a certain extent the prevention and control of early stage Weeds in nursery has been played to certain effect. SoAnd, tea tree nursery lot seedbed paving yellow soil, the use amount of yellow soil is large, every 667m²Need to use yellow soil 20-25m³. Yellow soil resourceLimited, and take time-consumingly, take higher cuttage and seedling culture cost. How can be without spreading subsoil, take certain skillAfter art measure, can on seedbed, grow seedlings by cuttage? adopt desinsection, sterilization and herbicide to carry out nursery bed disinfection, can reach thisOne technical requirement. But such disinfection technology, dosage large (needing to control whole nursery lot topsoil content of microorganisms), exceptMedicine needs outside certain cost drops into, certainly will cause more serious pollution to environment, do not meet current green agriculture developmentRequirement. So the method that adopts chemical agent to sterilize is not generally adopted in tea tree single-node cutting seed-raising technology.CN200510060922.2, factorial seedling-culturing method for tea tree (Tea Inst., Chinese Academy of Agricultural Sciences), discloses a kind of tea treeFactorial seedling-culturing method, cutting medium is the peat that adopts artificial preparation: vermiculite: perlite=2:1:1, urgees by greenhouseEnter the growth of tea tree, the cutting medium of artificial preparation, content of microorganisms is low, but cost is higher, and need chamber facility condition, educateSeedling cost is too high. Only have the disinfection technology of nature environmental protection, just likely thoroughly solve the paving in tea tree single-node cutting seed-raising technologyA yellow soil difficult problem, impelling this technology to get is substantial progress.

Summary of the invention

For removing from upper berth, seedbed, tea cutting ground yellow soil, reach and directly on original soil, carry out tea tree single-node cutting seed-raisingObject, the invention provides the method for a kind of tea tree nursery lot covering film in summer sterilization weed eradication.

The technical solution used in the present invention is as follows:

A method for tea tree nursery lot covering film in summer sterilization weed eradication, is characterized in that, by tea tree nursery lot original soil warpAfter certain processing, do seedbed, the processing procedure of described nursery lot original soil is as follows: select early summer to early autumn in a certain period, at tea tree skewerSlotting nursery lot carries out covering film processing, and keeps the humidity of seedbed abundance, utilizes fine hot high temperature and the effect of sunlight in this period,Make the seedbed under covering film produce damp and hot high temperature, kill microorganism, weeds and seed thereof in top layer, seedbed cuttage soil, make formerSoil seedbed reaches the required soil environment condition of tea tree single node cutting.

In described early summer to early autumn in a certain period, refer to a certain period of mid-June to early September, needs the highest temperature to reach 35The fine hot weather more than DEG C is more than 10 days, and the summer inserts and selects to start mid-June covering film, and autumn sowing selects early August to start covering film.

Described covering film, refers to preparing the tea tree nursery lot used of cuttage on request after whole good furrow, carries out covering film placeReason, comprises the whole covering with plastic film of furrow face and ditch, the overlapping part in place that mulch film joins, and press some soil blocks, prevent mulch film quiltWind sweeps, and makes whole nursery lot ground in the relative sealing state of covering with plastic film.

The humidity of described maintenance seedbed abundance, after referring to rain or after irrigating, makes the seedbed moisture content that reaches capacity.

Beneficial effect of the present invention is:

(1) cuttage cost significantly reduces: covering film of the present invention is disinfected and can be killed seedbed cuttage soil layer more than 95%Fungal microbe, compared with paving yellow soil cuttage and seedling culture, basically identical on outplanting, but the laying of having saved yellow soilWork. Except the collection of yellow soil is laid cost, the nursery that covering film is disinfected, the weeds on ground, later stage cuttage garden are pulled outExcept managing, number of times is also less. Two totals, covering film every 667m that sterilizes²Nursery is saved direct cost and is reached more than 1000 yuan. Grow seedlingsCost is far below the breeding and seedling nursing with equipment such as greenhouse that adopts artificial substratum.

(2) protected yellow soil resource and ecological environment: a small amount of yellow soil is taken may not have for what impact, but large faceLong-pending nursery is in great demand to yellow soil, and each takes turns to grow seedlings and all need again to spread yellow soil, and yellow soil resource is to haveLimit, take in a large number and can exert an influence to landforms and ecological environment; The inventive method can for nursery stock provide one goodGrowing environment, reduces the generation of disease and pest, thereby reduces the use of chemical pesticide, so be self-evident to the protection of environment. The application of tea tree nursery lot covering film in summer sterilization weed eradication technology, significant to the protection of resource and ecological environment.
