Abstract
The chemical mainly consists of chloram phenicol as one kind of tetracycline medicine, methyl cellulose and xanthan gum. It is painted to the cut surface of diseased rubber tree and it can increase rubber yield by 14.27% while preventing and treating brown spot effectively.
Description
The invention belongs to the plant protection technology field.Specifically a kind of preventing and treating chemical for brown spot of rubber tree.
Brown spot of rubber tree is to open a kind of worldwide common important face disease of cutting bamboo grows, having a strong impact on the production of rubber, a lot of glue states that produce only take to stop the measure of cutting to the disease tree of brown spot of rubber tree, and the purpose of estate rubber tree is to obtain benefit in order to tap rubber, stopping cutting had not both had output, was difficult to make the disease tree to recover to produce the glue ability yet.China's brown spot of rubber tree is to produce one of higher country of the incidence of disease in the glue state in the world, the dead skin of high yield bud grafting tree stops the rate of cutting generally at 8-10%, seedling tree reaches more than 10%, sick tree belongs to the bark tissue necrosis of face, the brown back disease type that the glue ability is produced in the latex dust forfeiture more, and due to illness the dried glue of Ting Chaning is lost in more than 10%.For this reason, both at home and abroad the processing of brown spot of rubber tree is attached great importance to cutting again, the active measures that proposed some control brown spot of rubber tree in recent years replace the passive measure that stops cutting, as the pharmacotherapy measure of the shallow plane of focus in conjunction with compound trace element proposed, though certain effect is arranged, the shallow plane skin of focus method handles that the worker employed in a plant nursery is many, weak effect, plane skin difficulty greatly, the dispenser inconvenience burrows.
The purpose of this invention is to provide a kind of hybrid medicine control brown spot of rubber tree, it can prevent the generation of brown spot of rubber tree effectively, simultaneously can play therapeutic action preferably to brown spot of rubber tree again,, improve bamboo grows and produce the glue ability to guarantee the bamboo grows ordinary production.
The present invention chooses the bark that typical foxiness is arranged at the strong intersection of the disease of bamboo grows secant focus, cut fritter near phloem cambium place and be organized as sample, earlier with 2.5% glutaraldehyde 0.1M PH, 7.4 phosphate buffer fixers, back with 2% osmic acid 0.1M PH, 7.4 phosphate buffer fixer double fixed, dewater through ethanol series, the expoxy propane dehydration, epoxy resin Epon812 embedding, the section of LK B-48001 type slice machine.Section is observed under the LEM-100X Electronic Speculum with acetic acid uranium, lead citrate double staining.Discovery can be observed the rickettsia-like organism (RLO) of various forms at large in disease tree stem phloem sieve tube cell section, the thalline size is 100-2400nm, and the wall film has the mentioned ridge-shaped projection, the about 20nm of wall thickness.And, all do not find RLO at the electron microscopic examination that the health of contrast is set.Therefore, the inventor thinks that the cause of disease of brown spot of rubber tree is exactly RLO.
The symptom feature of brown spot of rubber tree is that hypodermal layer has tangible foxiness focus on the secant, and binder removal reduces or binder removal not, causes the bamboo grows underproduction or does not produce.At the cause of disease and the symptom feature of brown spot of rubber tree, the inventor has invented a kind of preventing and treating chemical for brown spot of rubber tree, is named as the hybrid medicine and the using method thereof of " protecting 01 ", can prevent and treat brown spot of rubber tree effectively.
Preventing and treating chemical for brown spot of rubber tree provided by the invention, it is characterized in that forming (percentage by weight): tetracyclines (chloram phenicol) 0.05～0.10% by following substances, methylcellulose 1.0～1.5%, yellow first glue 0.01～0.03%, all the other are water.
Preventing and treating chemical for brown spot of rubber tree provided by the invention takes out the tree lace (or a week scraping the coating band around tree) on the bamboo grows secant earlier when using, immediately soup evenly is applied to (or on coating band) on the secant face then, the wide about 1-3 of this face centimetre.
The compound method that the invention provides medicament is:
(1) takes by weighing tetracyclines, methylcellulose, yellow first glue respectively by above-mentioned configuration proportion.
(2) place broken mixing and stirring of the medicinal powder that weighs up respectively and packing the place that cools stand-by.
(3) dispenser is preceding 2 days, gets the clear water of nonmetallic vessel splendid attire aforementioned proportion, pours the above-mentioned medicinal powder of having prepared then into, is stirred in the immersion water, park 2 days after, medicine fully dissolves, and is stirred into the glue suspension, is guarantor's 01 medicament of the present invention, can use.
When using medicament of the present invention, if just open cut treelet and in, use on the hypopathia tree, the Best Times that is coated with medicament for the first time is to have opened when cutting just to carry out, later on every the one and a half months coating once.Dial except that the tree lace on the bamboo grows secant during each dispenser, and evenly be applied on secant and the top face with the hairbrush dip in liquid medicine immediately, width 1-3 centimetre, tap rubber by the system of normally cutting behind the coating, do not need not to cut.If middle age above brown spot of rubber tree stop cutting on the tree and use, can choose the normal bark of binder removal and cut again, in positive cutter or the moon line below 5-6 centimeters of lancinating, be parallel to secant, enclose around tree and to scrape wide coating band for 1-1.5 centimetre a week, the degree of depth gets final product to scrape off tertia, immediately coating.Coating Ying Yukai cuts pre-treatment for the first time, and ring-type rossing coating once can be tapped rubber after each the processing routinely at quarterly intervals later on.
If mix use, required ethrel or the former medicine of other stimulant added to use after stirring in the medicament of the present invention with ethrel or other bamboo grows stimulant.
Advantage of the present invention is the pathogenesis and the pathogen of having understood fully brown spot of rubber tree, develops and can prevent and treat the confection of brown back disease effectively, uses this chemical control brown back disease, it is good to have preventive effect, easy and simple to handle, improve gum output, to characteristics such as gum have no side effect.According to thalline situation of change before and after the electron microscope observation coating, the result shows: the disease-preventing and yield-increasing mechanism of medicament of the present invention is that medicine is fallen ill inhale in the gum tissue after, destroy thalline, thereby control the state of an illness of rubber brown back disease.In some just susceptible and not downright bad tissues, because this medicament has suppressed the activity of germ, thereby recovered the normal physiological function of gum and produced the glue function, play the effect of disease-preventing and yield-increasing.Use the present invention and prevent and treat brown spot of rubber tree, according to the statistics that 2,210,000 strains is coated with loblolly tree, control efficiency is 61.9-86.7%, after coating was executed medicament of the present invention, the incidence of disease of the sick tree of 1-3 level descended 2.8%, and the coating contrast tree incidence of disease does not rise 15%, spread the gumwood of this medicament, dried glue output generally has a net increase of produces 8.19-22.35%, on average increases production dried glue 14.27%, and dry rubber content has a net increase of 1.71-9.4%.Bamboo grows spreads medicament of the present invention, and average every strain increases income 2-2.54 unit, and cost and benefit ratio are 1: 4.53-6.23.
