Description

A kind of rice herbicide
Technical field
The invention belongs to pesticide fields, and in particular to a kind of rice herbicide.
Background technique
Rice belongs to most important one one kind in cereal crops, but efficient and green control is needed to have in production The case where evil is biological, prevents it from leading to grain drop in production.Cause rice underproduction many factors no more than weeds in weeds in paddy field, currently Taking the mode of chemical weed control becomes common mode, and occurs a variety of weeds in paddy field by developing corresponding weeding Agent and effectively control influence of the weeds to paddy field.The difference of combining form is analyzed, and the weeds in rice field can divide Be following several: the first is the leaf weeds of list, and second is dicots weeds, and the weeds of grass family and Cyperaceae It is then monocotyledonous weeds, broadleaf weeds is then dicots weeds, selects different remove referring to the type that this weeds divides Careless agent brings certain reference value.By the development of many years, the kind that can be used for herbicide in rice field and number Amount all with day increase severely, including type have: amides, diphenyl ether, bipyridyliums, sulfonamides, Tetrazoline series, carboxylate Class, quinoline carboxylic acid, organic phosphates, sulfonylurea and heterocyclic.And it is miscellaneous to be then divided into broad-leaved referring to the target of management of weeds Grass, gramineae weed, sedge weed and broad spectrum activity herbicide.
Chemical pesticide is the important leverage of modern agriculture good harvest, and wherein herbicide is that pesticide producing is formed with the maximum used Part.Although herbicide it is long-term, a large amount of, be widely used and promote Food Production, current herbicide is not thorough to weed eradication Bottom, and bio-toxicity is big.Therefore, producing a kind of efficient rice herbicide has very big market prospects.
Summary of the invention
The technical problems to be solved by the invention: it is big for current rice herbicide bio-toxicity, and it is unfavorable for spike of rice fruit Real problem, provides a kind of rice herbicide.
In order to solve the above technical problems, the present invention is using technical solution as described below:
A kind of rice herbicide, according to the mass fraction, including following component: 7 ~ 15 parts of Acetochlors, 2 ~ 6 parts of dispersing agents, 30 ~ 50 parts Water, which is characterized in that further include: 20 ~ 35 parts of eucalyptus allelopathy compounds, 15 ~ 30 parts of rice from source press down careless compound, 50 ~ 70 parts of coating solutions.
The preparation method of the eucalyptus allelopathy compound, includes the following steps:
(1) eucalyptus root system is taken, dissection, in mass ratio 1:4 ~ 7 are dipped in nutrient solution, and in 35 ~ 45 DEG C of wet ball grindings, filtering takes filter residue Washing, obtains washing lotion, takes washing lotion to be added among filtrate, obtains mixed liquid, takes mixed liquid to be evaporated in vacuo in 45 ~ 60 DEG C, is concentrated under reduced pressure into substance Long-pending 15 ~ 35% obtain eucalyptus root system extracting solution, spare；
(2) according to the mass fraction, take 7 ~ 15 parts of eucalyptus root systems without sward earth, 0.5 ~ 1 part of NaH2PO4, 30 ~ 50 parts of glucose, 1 ~ 3 Part (NH4)2 SO4, 5 ~ 10 parts of sodium glutamate, 16 ~ 25 parts of perilla herb oils, 3 ~ 8 parts of KCl, 0.2 ~ 0.6 part of CaCO3, 0.4 ~ 0.8 part MgSO4·7H2O, 0.1 ~ 0.3 part of VB12, 600 ~ 800 parts of water mixing, shaking table oscillation, closed culture, filtering obtains culture solution, takes training Nutrient solution is evaporated in vacuo to the 35 ~ 55% of original volume, obtains concentrate, takes concentrate 1:15 in mass ratio ~ 20 that hair is added in 20 ~ 25 DEG C It is cultivated in ferment culture medium, vibrates shaking table culture, centrifugation, removal centrifugation object obtains fermentation liquid, is evaporated in vacuo, obtains eucalyptus root soil Culture；
(3) 5:2:0.1 ~ 0.4 takes spare eucalyptus root system extracting solution, eucalyptus root soil culture, bigcatkin willow acid-mixed in mass ratio Close stirring, stand, obtain premixed liquid, take premixed liquid 8:0.2 in mass ratio ~ 0.6 be added regulator mixing, ultrasonic wave dispersion to get Eucalyptus allelopathy compound.
Nutrient solution in the step (1): according to the mass fraction, 2 ~ 5 parts of MgSO are taken4·7H2O, 1 ~ 4 part of CaCl2· 2H2O, 2 ~ 6 parts of NH4NO3, 5 ~ 8 parts of K2SO4, 2 ~ 6 parts of KH2PO4, 0.2 ~ 0.6 part of vitamin B1, 15 ~ 25 parts of glucose, 800 ~ 1000 Part water mixing, in 121 DEG C of sterilizing 15min to get nutrient solution.
Fermentation medium in the step (2): according to the mass fraction, 100 ~ 120 portions of potatos, 10 ~ 15 parts of lactose, 2 ~ 5 are taken Part yeast extract, 1 ~ 3 part of dipotassium hydrogen phosphate, 0.05 ~ 0.07 part of magnesium sulfate, 0.01 ~ 0.03 part of calcium chloride, 0.2 ~ 0.5 part of phosphoric acid hydrogen Disodium, 0.01 ~ 0.03 part of vitamin B1, 700 ~ 900 parts of water, sterilize to get fermentation medium.
Regulator in the step (3): 2 ~ 6:5:4:10 in mass ratio takes methyl α-naphthyl acetate, indolebutyric acid, ammonium sulfate, water mixed It closes to get regulator.
The rice presses down the preparation of careless compound from source: in 35 ~ 50 DEG C, 1:4 ~ 7:15 ~ 20 take (NH in mass ratio4)2CO3、 Na2HPO4, water mixing, be mixed, obtain just mixed liquid, take just that component A, component B is added is mixed by mixed liquid 7 ~ 10:1 in mass ratio ~ 3:1:1 It closes, supersonic oscillations press down careless compound from source to get rice.
The component A: 4:1 ~ 2:1 in mass ratio takes methyl α-naphthyl acetate, indolebutyric acid, diethyl aminoethyl hexanoate mixing to get component A.
The component B: 6:1 ~ 2:3 in mass ratio takes polyallylamine, polyethyleneimine, phosphatide mixing to get component B.
The preparation of the coating solution: in 75 ~ 85 DEG C, 6:0.2 ~ 0.5:2:15 ~ 20 in mass ratio take starch, casein, sugarcane Sugar, water are mixed, and obtain mixed liquid, take mixed liquid that the peanut of the sodium carboxymethyl starch of mixed liquid quality 3 ~ 8%, mixed liquid quality 4 ~ 10% is added Tetraenoic acid mixing, high speed shear dispersion are homogeneous to get coating solution.
The dispersing agent: 5:1 ~ 2 take lauryl sodium sulfate, guar gum mixing to get dispersing agent in mass ratio.
The present invention is compared with other methods, and advantageous effects are:
(1) present invention is operated using eucalyptus root system as raw material through Solution culture method, wet ball grinding etc., significantly improves root system secretion phenol The leaching of acid, using eucalyptus root system without sward earth as raw material, through various nutrients rejuvenation, fermentation, generating a variety of has Machine matter, eucalyptus allelopathy compound, in combination with surrounding growth environment, can form biological allelopathic and make when the present invention comes into operation It is significant to the inhibiting effect of weeds with system, strengthen rice to the scoopability of nutrient, reaches biology and press down careless herbicidal effect；
(2) present invention is with polyimides, (NH4)2CO3Deng for raw material, mixing compounding, rice processed presses down careless compound from source, can promote Rice plant grows tall, strengthens tillering ability, improves tiller number, and the effective rice itself that promoted improves rice to the patience of weeds The ability of draw nutrient can be such that suppressing weed seed germination greatly reduces, and lack nutrition and remove, and then play the work for inhibiting weeds With polyallylamine and polyethyleneimine in component B, during processing, primary amino group can in polyallylamine and polyethyleneimine It is crosslinked under the action of the carbon dioxide of rice root slow release, forms polymer three-dimensional network on rice root surface Structure, and carbon dioxide fixation is absorbed in its surface as carbon fertilizer, and the disease-resistant and biocidal property of itself of rice can be improved Can, polyallylamine and polyethyleneimine can also gradually degrade, provide nutritional ingredient by rice absorbing, under the cooperation of coating solution, It can reach long-acting supplement nutrient again, press down careless herbicidal effect.
