Description
Technical field:
The invention belongs to plant pest management technical field, relate to a kind of composition of the control leek diseases and insect pests utilizing natral plant ingredients and taste to be prepared into, particularly a kind of composition preventing and treating leek diseases and insect pests.
Background technology:
In recent years, malicious leek event happened occasionally, and malicious leek is the insect in order to prevent and treat harm leek root, the noxious material such as a large amount of applying pesticides in leek planting process, apply dose not according to safety standard, cause residue of pesticide to exceed standard seriously, acute poisoning after even causing consumer edible, usually, the insect of harm leek plantation has borer, Liriomyza etc., borer is raw in soil, specially sting Radix Folium Allii tuberosi, Radix Folium Allii tuberosi is bitten broken just cannot normal growth, therefore vegetable grower administers this insect and pours in pestsides synthesis to water exactly, the insect of ensconcing in soil is killed, the vitality of borer is extremely strong, general agricultural chemicals is difficult to kill, so, the insecticidal power that some vegetable grower just lists violated list in country by force and the not labile agricultural chemicals of medicament residue, water or spray in process, absorbed by leek and cause residue of pesticide, after people have eaten this leek, it remains and eater can be caused to have a headache, dizzy, unable, hidrosis, vomiting, diarrhoea etc., expiratory dyspnea can be there is in severe person, stupor, the symptom of the life threatenings such as blood cholinesterase activity decrease, on April 1st, 2010 starts, and Qingdao " malicious leek " event raises fear, the patient that hospital is poisoning after receiving 9 edible leek successively, on March 25th, 2011, there is malicious leek event in Nanyang City, Henan Province, and malicious leek is found the residual severe overweight of agriculture, in order to stop the generation of malicious leek, will keep under strict control from source, finding natural plants and harmless composition composition killing insect pest medicine, become an important problem, according to the study, many natural plant compositions have the effect of antibacterial expelling parasite desinsection, the multiple natral plant ingredients with antibacterial insecticidal action is passed through reasonable preparation, make spray liquid or pouring liquid, then periodically sprinkle or be poured onto on leek, can play the effect suppressing germ, again can desinsection expelling parasite, can also have plant nutrition fertilizer function, be the really natural environment-friendlyplant plant agricultural chemicals preventing leek diseases and insect pests, there is not yet the technical scheme of pertinent literature report such composition so far.
Summary of the invention:
The object of the invention is to the shortcoming overcoming prior art existence, seek to design a kind of with tobacco leaf for primary raw material adds the composition of the control leek diseases and insect pests that the natral plant ingredients such as garlic and argy wormwood is prepared into again, to solve injury that residue of pesticide cause human body and the pollution to surrounding ground and air ambient.
To achieve these goals, the main component of the composition that the present invention relates to comprises:
The preparation technology of the composition that the present invention relates to comprises the preparation of tobacco slurries, the preparation of garlic slurries, the preparation of argy wormwood slurries, the preparation of pumpkin seeds juice and composition and prepares five steps;
(1) tobacco slurries preparation: get cadmium yellow tobacco leaf and stalk, be cut into the bulk of 1-2cm, put into beater, in fresh tobacco leaf and stalk: the weight ratio of distilled water is that the ratio of 1:3 ~ 5 adds distilled water, mixing polishing 5 ~ 10 minutes tobacco slurries;
(2) garlic slurries preparation: choose the band root straw garlic without rotting without assorted soil, in garlic: ethanol water is the ratio of 1:2 ~ 3, it is for subsequent use that mixing is polished into garlic slurries, and wherein the weight percent concentration of ethanol water is 3 ~ 5%;
(3) argy wormwood slurries preparation: win fresh argy wormwood, after first rinsing with the saline solution that weight percent concentration is 3 ~ 10%, put into the bulk that vegetable-chopper is cut into 1-2cm, lower than under the environmental temperature of 25 DEG C, by fresh argy wormwood: distilled water is the part by weight of 1:3 ~ 5, it is for subsequent use that mixing is polished into argy wormwood slurries;
(4) pumpkin seeds juice preparation: get completed belt shell pumpkin seeds, first by pumpkin seeds: distilled water is after pumpkin seeds are soaked 2 ~ 5 hours by the part by weight of 1:2 ~ 4, then it is for subsequent use to be polished into pumpkin seeds juice;
(5) composition preparation: take tobacco slurries, garlic slurries, argy wormwood slurries and pumpkin seeds juice respectively by weight, the temperature that controls environment is lower than 25 DEG C, each slurries are put into agitator tank and stir 5-10 minutes to after mixing, bottling or pack pack, obtain composition finished product, the percentage by weight of its ethanol is less than 1%, and the shelf-life is 2-10 days under lower than 25 DEG C of environment.
Composition product prepared by the present invention can after solids removed by filtration particle, and dilute with water 2-3 is doubly directly sprayed onto leek blade face, reach antibacterial, expelling parasite, disinsection efficiency, or directly water to leek root without filtration, reach expelling parasite insecticidal effect, and the growth of leek can be promoted, improve output.
Compared with prior art, its preparation technology is simple, noresidue harmless to leek, and to human non-toxic's side effect, processing cost is low, and raw material is easy to get, and can make by oneself personal in the present invention, and applied environment is friendly.
