Abstract

The invention discloses a reagent for preventing and curing apple-tree valsa canker. The reagent is prepared from, by weight, 6-8 parts of dandelion extract, 8-15 parts of radix aconiti kusnezoffii, 8-12 parts of perilla frutescens leaves, 28-35 parts of cortex magnoliae officinalis, 2-4 parts of tuba roots, 12-18 parts of wrinkled gianthyssop herbs and 25-30 parts of pine needles. Compared with the prior art, the reagent has the advantages that the raw materials are all plant materials, antibiotics are not contained, the reagent is applied directly in the injection mode or the fertilization mode, and medicine losses caused by poor medicine permeability can be avoided; the medicine acts inside a trunk, pathogenic bacteria of apple-tree valsa canker can be killed, and fungi diseases such as apple valsa canker are prevented.

Description

A kind of reagent preventing and treating apple valsa canker

Technical field

The invention belongs to technical field of agricultural breeding, be specifically related to a kind of reagent preventing and treating apple valsa canker.

Background technology

Apple valsa canker is a kind of trunk disease, is the Chinese medicine disease of northern China apple tree, usually can cause that tree vigo(u)r is weak, limb is withered, and dead tree even ruins garden.Trace it to its cause, mainly have casting skin shell bacterium to cause, germ survives the winter in the cortex of field diseased plant and invalid body with mycelium, pycnidium and perithecium, when temp. and humidity is suitable, constantly sprout in bark, destroy plant tissue, finally cause cortical tissue downright bad.Existing method of much preventing and treating rot at present, how to focus on during the spring in autumn, but usually can not get good prevention effect, in the annual 5-9 month, easily can sprout rotten pathogenic bacteria, therefore need to control infecting of rotten pathogenic bacteria in this period, and conventional prevention and controls is for after scraping and debarking, daubing medicament, this method could can only be implemented after the sick abnormal pigmentary deposit on the skin of discovery, usually late, cause rot comparatively serious, even if cure, also can next year be more serious again, at present commercially mostly be chemical agent for what prevent and treat apple valsa canker in addition, control efficiency is poor, and effective drug duration is short, need repeatedly to use, on the other hand, the permeability of chemical reagent is very poor, from and extend treatment time and as effect, therefore, need a kind of medicament and the application process thereof that can give full play to drug effect, avoid the waste because apple valsa canker causes.

Summary of the invention

The object of the invention is for existing problem, provide a kind of reagent preventing and treating apple valsa canker.

The present invention is achieved by the following technical solutions: a kind of reagent preventing and treating apple valsa canker, is made up of the raw material of following weight portion: dandelion extract 6-8 part, radix aconiti agrestis 8-15 part, perillaseed leaf 8-12 part, bark of official magnolia 28-35 part, trifoliate jewelvine 2-4 part, wrinkled giant hyssop 12-18 part, pine needle 25-30 part.

As further improvement of these options, preparation method comprises the following steps:

(1) get the alcohol immersion 3-4 days of the radix aconiti agrestis of corresponding deal, perillaseed leaf, the bark of official magnolia, wrinkled giant hyssop and pine needle 100 weight portions, filtration obtains filter residue and ethanol filtrate is for subsequent use;

(2) filter residue is added respectively the soak by water twice of 200 parts, decoction temperature is 55-65 DEG C, and the time is 2-3 hour, twice is filtered the mixing of gained filtrate, is mixing filtrate;

(3) stir after mixing filtrate and ethanol filtrate mixing and be heated to 60 DEG C, keeping 20-40 minute, leaving standstill to cooling for subsequent use;

(4) get the trifoliate jewelvine of corresponding deal, soak 2 hours in the acetum of 15 part 2%, then filter and obtain acetic acid filtrate;

(5) mixed by gained mixed liquor in acetic acid filtrate and step (3), then add dandelion extract and stir, then reduced pressure concentration is 1/10th of original volume, encapsulates under the high temperature conditions, gets product.

Obtain through experiment, in the present invention, reagent drug effect can keep 20-25 days, therefore uses once every 20 days; During use, concentrate is diluted 100 times, with tree injector injection, the injection volume of every tree is 5-8ml at every turn, also can be used in combination with chemical fertilizer, growth regulator; After fruit tree is ill, the usage amount of every tree is increased to 15-18ml, every other day injects once, suitably reduces dosage after injecting 5-7 time continuously according to fruit tree recovery situation.

In addition, in the present invention, gained reagent is also applicable to the control of similar fruit tree putrefaction disease.

The present invention has the following advantages compared to existing technology: in the present invention, raw material are vegetable material, not containing antibiotic, the direct mode of injection or fertilising that adopts is used, the drug loss because drug permeability difference causes can be avoided, medicine is in trunk internal action, the pathogen of apple valsa canker can be killed, the generation of the fungal diseases such as prevention apple canker.
