Abstract

The present invention discloses a natural kiwi protecting medicament and a preparation method therefor. The natural kiwi protecting medicament is prepared from the following raw materials in parts by weight: Litsea cubeba, n-hexane, 95-98% concentrated sulfuric acid, garlic bulbs, saponin, ginkgo leaves, neem nuts, sodium chloride, ginger powder, industrial castor oil, bentonite powder, fine anklet sporamycin, 80% ethanol and a proper amount of water. Antibacterial components adopted in the medicament all come from components extracted from plants, so that toxicology resistance of plants for pathogenic bacteria is fully exerted, usage of chemical toxic components is reduced, so that deposition effects of toxin on fruit trees and even fruits are reduced, and the planted kiwis can be more sanitary and healthy. Many problems such as environment pollution, food safety and the like caused by pesticide are avoided.

Description

A kind of natural Actinidia chinensis protection medicament and preparation method thereof

Technical field

The invention belongs to the technology field of agricultural chemicals, be specifically related to a kind of natural Actinidia chinensis protection medicament and preparation method thereof.

Background technology

In recent years, China uses 1,000,000 tons, agricultural chemicals control area to reach the crops of more than 300,000,000 hectares every year, plant protection service is that agricultural foison has made tremendous contribution, serve the effect escort, but due to the operation technique of agricultural chemicals and the research wretched insufficiency of technical measures, ignore target organisms behavioral study and generally adopt Large Copacity, the reasons such as large droplet spray technique, China's pesticide efficacy is low, the agricultural chemicals shed by spraying equipment only has 20 ~ 30% can be deposited on crop, be equivalent to the average level of developed country 50%, poor efficiency in Pesticide use, not only waste a large amount of agricultural chemicals, a large amount of pesticidal preparations is also made to be lost in non-target environment, cause person poultry poisoning, environmental pollution, Practice for Pesticide Residue in Agricultural Products amount increases.

The poor efficiency of Pesticide use also has much relations with pesticide processing technical research deficiency, China has become pesticide producing big country, but domestic preparation, the research of formulation and the quality of product compared with abroad appoint there is a big difference, main manifestations is that dispersive property is poor, suspensibility is low, the aspects such as heat storage resolution ratio is high, some formulations are because of wettability, the reasons such as permeability and blade face deposition difference cause drug effect unstable, be equivalent to a part of kind and be obviously worse than same kind of products at abroad in resistance of rainwater washing against and viscosity etc., as domestic pesticide suspension concentrate ubiquity bleed, multiviscosisty, deposition, the problems such as the bin stabilities such as caking.Occur the main cause of this phenomenon except the kind quality and quantity with China agricultural chemicals medicinal surfactant compared with developed countries gap greatly except, also not enough etc. relevant with action of agricultural chemicals study mechanism to just surface-active agent with us.

Summary of the invention

In order to alleviate Pesticidal products bad dispersibility, suspensibility is low, and degraded slowly, the problems such as residual height, the present invention adds a kind of bioactive surface reactive material by modification, improves the result of use of pesticidal preparations, lower Pesticide use frequency, realize particular by following methods:

A kind of natural Actinidia chinensis protection medicament, it is characterized in that, be made up of the raw material of following weight portion: the ethanol 40 ~ 50 of the concentrated sulfuric acid 2 ~ 4 of the fruit of a cubeb litsea tree 10 ~ 15, n-hexane 1.5 ~ 3,95 ~ 98%, garlic bulb 8 ~ 10, Chinese honey locust 12 ~ 16, ginkgo leaf 4 ~ 6, neem fruit 15 ~ 20, sodium chloride 5 ~ 8, ginger slag 10 ~ 15, industrial castor oil 12 ~ 16, bentonite micro mist 0.5 ~ 1, thin pin Neurospora element 3 ~ 6,80% and appropriate water;

A preparation method for natural Actinidia chinensis protection medicament, is characterized in that, comprise following step:

(1) fruit of a cubeb litsea tree is pulverized through preliminary, then add the water of 2 ~ 3 times of its weight portions, add n-hexane, decoct 2 ~ 2.5h, the cooking liquor of filtration, continue heating 2 ~ 3h and concentrate, finally add 95 ~ 98% concentrated sulfuric acids, be heated to 80 ~ 90 DEG C, after insulated and stirred 15 ~ 30min, obtain extract;

(2) mix garlic bulb, Chinese honey locust, ginkgo leaf, neem fruit, sodium chloride and ginger slag, first preliminary pulverizing, then extremely dry through 100 ~ 120 DEG C of high-temperature baking 8 ~ 10h, the powder of ultramicro grinding to 180 ~ 200 mesh sieve, join in the ethanol of 80%, be warming up to 70 ~ 80 DEG C, utilize the process of ultrasonication crusher machine to obtain slurries;

(3) to the slurries described in (2) carry out centrifugal after supernatant, leave standstill after 20 ~ 25min, low pressure evaporation backflow carried out to supernatant, obtains concentrate;

(4) by extract mixed industrial castor oil, bentonite micro mist and other residual components described in (1), be added in the concentrate described in (3), in closed reactor, high speed centrifugation shear-mixed 15 ~ 25min, finally in uniform emulsion.

Litsea cubeba oil mainly concentrates in pericarp, and the residue main component after pulverizing is fruit of a cubeb litsea tree kernel, and in these kernels, containing natural grease, crude protein, raw fiber and the material such as calcium, phosphorus, wherein natural oil reaches 25 ~ 28%.The present invention obtains a certain amount of natural surface reactive material by decoction-pulverizing-squeezing-rough acid refining, wherein in the process decocted, add a certain amount of organic solvent-normal hexane, accelerate the speed of stripping grease and improve extraction efficiency, a certain amount of concentrated sulfuric acid is added after completing, add the acid refining of stirring and carrying out litsea cubeba kernel oil, containing various surface reactive material in products therefrom, as lauric acid Sulfates, metal carboxylate, the a series of surface reactive material such as alkanolamide, alkanolamide wherein has stronger anti-hydrolytic performance, there is significant foam enhancing, steady bubble, the effects such as thickening.

Utilize the surface reactive material of fruit of a cubeb litsea tree extracting natural, reduce the use of chemically reactive substance, reduce the use of the non-renewable energies such as oil, use the surfactant that chemistry refines simultaneously, more or less introduce unnecessary impurity, contaminated environment, after adding the surface reactive material of natural extraction, significantly can accelerate the contact of agricultural chemicals and the wax coat page, significantly stick together on blade simultaneously, retention time is more of a specified duration, and vermins-proof effect is more obvious, reduces the usage amount from agricultural chemicals from the side.

Beneficial effect of the present invention: containing allicin in garlic bulb, all antibacterial action is had to multiple Gram-positive and negative bacterium, suppression killing action is all had to bacillus (shigella dysenteriae, typhoid bacillus, Escherichia coli, Bordetella pertussis), fungi (Candida albicans, cryptococcus, aspergillus fumigatus), virus (cytomegalovirus), Amoeba, Trichomonas vaginalis, pinworm etc., Celastrus angulatus and Dai are all botanical pesticide, therefore can not produce resistance.

The antimicrobial component adopted in invention is all from plant extract component, give full play to the toxicity resistance of plant to pathogen, reducing the use of chemical toxicity composition, thus reduce the deposition of toxin on fruit tree or even fruit, is kiwi fruit health, the health more of plantation.Avoid much because of environmental problem, food-safety problem etc. that agricultural chemicals brings.
