Description

A kind of compound drug preventing and treating rape aphid and preparation method thereof

Technical field

The present invention relates to the Prevention Technique field of damage by disease and insect, be specifically related to a kind of compound drug preventing and treating rape aphid and preparation method thereof.

Background technology

Rape (BrassicacampestrisL.var.amplexicaulisMakino), belongs to Cruciferae Brassica genus, more year life or annual herb plant.Have another name called rape, cold dish, recklessly dish, bitter dish, tongue mustard, green vegetables.Stem is cylindrical, multi-branched.Leaf alternate.Raceme, brightly yellowish look fresh, and flowering stage is long, and nectary is flourishing.Knot siliqua, seed is spherical, has the colors such as red, yellow, black, oil content 30 five to percent percent 50.Originate in China, color is dark green, and side, as Chinese cabbage, belongs to the mutation of Cruciferae Chinese cabbage.North and south is widely cultivated, and the four seasons all have for producing.Quality is tender and crisp, slightly bitter taste.The signboard nutrient content of rape and food therapy value thereof can deserve to be called the outstanding person in all kinds of vegetables.Research shows, containing various nutrients in rape, contained vitamin C is higher than Chinese cabbage more than 1 times.Promoting blood circulation and removing blood stasis, removing toxicity for detumescence, wide intestines defaecation, improves the health.Cure mainly urticaria erysipelas, brothers' furuncle, acute mastitis, habitual constipation, the illnesss such as the elderly's calcium deficiency.

The main in the course of cultivation damage by disease and insect of rape has aphid, Liriomyza etc.Because cultivated area constantly expands, add that rape is planted year after year, rape aphid occurs general, and harm is serious, have impact on the yield and quality of rape, thus affects the enthusiasm for production of peasant.

In prior art, the control of rape is mainly and flutters the 1800 times of liquid sprinklings of lice aphid with 20% Belmark, 2000 times of liquid or 2.5%.China Patent No. is that CN103621519A discloses a kind of medicament killing aphid, this formula is made up of the raw material of following parts by weight: carbamate 10 grams, sumicidin 2 grams, galecron 1.5 grams, fluosilicic acid receives 0.5 gram, neopelex 3.1 grams, chilli oil 8 grams, this formula is mainly based on chemicals, though good insecticidal effect can be played, but use and chemical pesticide too much can be caused too much residual, and then infringement health, be and Chinese patent CN102067887B discloses a kind of anti-preparation eliminated aphis, this invention utilizes pine needle (to comprise masson pine, the needle of the pine trees such as black pine) extract, obtained biological killing aphids preparation, this invention utilizes the active ingredient in acetone extraction pine needle to be prepared into paste, acetone is that a kind of organic solvent has extremely strong volatility, poisonous, have retaining of solvent unavoidably, after entering human body, organ can cause serious organic disease, therefore, safety in utilization is poor.

Summary of the invention

The object of the invention is to avoid the deficiencies in the prior art, provides a kind of compound drug preventing and treating rape aphid, this compound drug preparation method is easy, cost is low, use after without any residue of pesticide, safety, good for the control efficiency of aphid.

Prevent and treat a compound drug for rape aphid, be made up of the raw material of following parts by weight:

Root of Herba Houttuyniae 8-12 part, leaves of Hawthorn 6-10 part, bunge pricklyash leaf 5-10 part, lemon grass (Cymbopogon citratus) 5-8 part, leek seed 3-6 part, Fructus Aurantii leaf 6-10 part, tuber of stemona leaf 15-20 part, bloodroot element 7-12 part, grassleaf sweetflag leaf 3-5 part, 15%-20% sodium chloride solution 20-30 part, Sodium Tvlose 1-2 part, macadamia nut oil 5-10 part

The present invention also provides a kind of compound drug preventing and treating rape aphid, comprises the following steps:

(1) get the leaves of Hawthorn of described parts by weight, add leaves of Hawthorn weight 2-3 water infusion 15-30min doubly, elimination residue, obtains leaves of Hawthorn Aqueous extracts;

(2) get the bunge pricklyash leaf of described parts by weight, the absolute ethyl alcohol lixiviate 2-3h of bunge pricklyash leaf weight 1.5-2 times 75% is added after blending with pulper, decompression recycling ethanol, then adds the distilled water of leaching liquor weight 1/3rd in the leaching liquor of gained, obtains Chinese prickly ash alcohol extract;

(3) get the Fructus Aurantii leaf of described weight fraction, 2-2.5 that grassleaf sweetflag leaf, tuber of stemona leaf add respective weight respectively doubly 50%, 60%, 70% absolute ethyl alcohol add hot reflux lixiviate 20-30min, 15-20min, 10-15min, filter respectively, filtrate is for subsequent use, Fructus Aurantii leaf filter residue, grassleaf sweetflag leaf filter residue, tuber of stemona leaf filter residue are dried naturally, pulverized 40 mesh sieves, the macadamia nut oil adding above-mentioned weight fraction after mixing mixes, and leaves standstill 4-10h, filter, obtain miscella extract;

(4) the lemon grass (Cymbopogon citratus) of getting described parts by weight smashs the pure water putting into its half weight to pieces, and 200 ~ 250 DEG C water decoct 20 ~ 30 minutes, filters and obtains lemon grass (Cymbopogon citratus) extract;

(5) get the leek seed of described parts by weight, root of Herba Houttuyniae is pulverized, cross 40 mesh sieves respectively, then add bloodroot element, the molten 20-30 part of 15%-20% sodium chloride, Sodium Tvlose after mixing, after stirring, add the lemon grass (Cymbopogon citratus) Aqueous extracts prepared by step 4, for subsequent use;

(6) after the raw material mixing and stirring prepared by step 1-5, be placed in materials decoction device, after heating decocts, extract a not good liquor; Add water again and continue to decoct, extract two not good liquors; Add water again and continue to decoct, extract three not good liquors; By a not good liquor, two not good liquors, three not good liquors merge together, carry out heating and concentrate, obtain inspissated juice, after filtration, add inspissated juice weight 1-1.5 distilled water diluting doubly, must prevent and treat the compound drug of rape aphid.

Beneficial effect of the present invention is:

1, the present invention with the addition of plant-derived insecticidal constituent such as: bloodroot element, tuber of stemona leaf etc. can effectively preventing rape aphids, the fast quick-recovery of rape can be promoted, improve the survival rate of rape, comprehensive nutrition can absorb rapidly and enter in rape body, for rape supplements the nutrients rapidly, strengthen its resistance.

2, proportioning science of the present invention, preparation method is simple, easy to use, and this additive is nontoxic, safe and effective, has both avoided the poisoning of chemicals and the pollution problem to environment thereof.
