Abstract
The invention relates to an additive of weed killer, wherein it is formed by 0.01-5% 4-hydroxycoumarin and 95-99.99% abies. The inventive additive can be used with weed killer, to accelerate the decomposition of left weed killer, and improve the effect of killer. The invention can eliminate bad root, low growth, etc. And the tests have proved its effect.
Description
Technical field
The present invention relates to a kind of herbicide safety additive.
Background technology
China is that an Agricultural Bio-disasters takes place frequently, one of large agricultural country of agroecological environment fragility, China region is wide, weather conditions are different, and farmland weed is of a great variety, and the important weeds that agricultural production is worked the mischief have kind more than 50, cause the malignant weed of serious harm that kind more than 20 is arranged, China farmland is subjected to the weeds hazard area to be about 6,000 ten thousand hectares every year, 3,000 ten thousand hectares of serious injured areas, and direct economic loss is up to more than 200 hundred million RMB.In January, 26.4%, 2005 China's weed killer herbicide output that present weed killer herbicide output in China's registration accounts for the pesticide producing total amount increases by 46.4% on a year-on-year basis.Along with China's weed killer herbicide research and the development of producing, present national farmland chemical herbicide popularizing area has reached 1,000,000,000 mu times, and modern agriculture is more and more stronger to the dependence of weed killer herbicide.Yet because the application of agricultural chemicals such as chemical herbicide, chemical pesticide is residual and pollute the life that has promptly endangered the people, has brought serious disaster to agricultural production again.The harm of weed killer herbicide on agricultural generally has following several: (1) recessive poisoning, poisoning directly perceived; (2) hide poisoning, the outburst poisoning.Recessive poisoning mainly occurs in crop such as wheat when the seedling spraying weed killer herbicide, import or homemade outstanding weed killer herbicide have been selected, though these weed killer herbicides can not cause poisoning directly perceived, but can have influence on the reproductive growth of crops such as wheat, make crop roots such as wheat undeveloped, minimizing is tillered, and resistance against diseases is poor, the incidence of disease is high especially, generally makes more than the crop failure 7-20%.Selected import or homemade part weed killer herbicide inferior when intuitively the poisoning first is owing to the spray medicine for use, made crops suffer the serious underproduction or total crop failure; It two is that blindly medication frequently occurs, can not be in strict accordance with period that requires and dosage medication because the level of peasant's medication is low; In addition, poisoning is to use residual the exceeding standard of chemical herbicide accumulative total year after year owing to hide, the outburst poisoning takes place in about more than 6,000 ten thousand mu of soils, Heilongjiang Province, area, China northeast in this year, weed killer herbicide is promoted relatively early in area, China northeast, chemical residual exceeds standard in the soil, and variation symptoms such as fertilizer are not lacked of proper care, dewatered, take off to length, stiff seedling, Huang Ye, dried point, photosynthesis to cause soybean, rice seedling dead seedling, mashed root, atrophy to occur.Investigate according to Ministry of Agriculture's agricultural chemicals evaluation, weed killer herbicide accounts for 80% in the various pesticide injuries of China, and herbicide residue and poisoning are very severe at present.
Summary of the invention
The object of the present invention is to provide and a kind ofly can repair that chemical residual exceeds standard in the soil that weed killer herbicide causes because of using, crops seedling stage occur dead seedling, mashed root, atrophy not length, stiff seedling, Huang Ye, do the herbicide safety additive that the symptom that makes a variation such as fertilizer was lacked of proper care, dewatered, takes off to point, photosynthesis.
To achieve these goals, technical program of the present invention lies in having adopted a kind of herbicide safety additive, is that the 4 hydroxy coumarin of 0.01-5% and turpentine oil that percentage by weight is 95-99.99% are prepared from by weight percentage.
Described 4 hydroxy coumarin purity is greater than 98%.
Described turpentine oil can be potassium dihydrogen phosphate.
4 hydroxy coumarin among the present invention, chemical name is: 4-hydroxyl-1,2-oxygen be ketone how, and molecular formula is C
9H
6O
3, outward appearance is a white, the pH value is 6-7, water content≤1%, purity 〉=98%; Turpentine oil is a kind of natural essential oil, is based on the mixture of the multiple terpene hydro carbons of firpene, has distinctive chemism.4 hydroxy coumarin is used in combination with turpentine oil and can be used for various crops in the present invention, its be mainly used in treatment because of herbicide residue, disease, poisoning, fertilizer damage, drought, waterlog, freeze etc. that natural calamity caused lacks not length, stiff seedling, Huang Ye, three symptom that makes a variation such as fall of the mashed root of the dead seedling how to cause, atrophy, spray additive of the present invention and restore normal growth substantially in 48 hours.The present invention be according to herbicide spraying on different crops lack composition how and replenish, make crop absorb the back and produce resistance weed killer herbicide, get rid of or decompose weed killer herbicide residual on crops.The present invention and herbicide mixture can quicken the residual decomposition after weed killer herbicide uses, and also can improve the drug effect of weed killer herbicide simultaneously; The present invention can eliminate the effect multiple diseases that the latent type poisoning because of weed killer herbicide causes; Solve the influence of herbicide residue, eliminate dead seedling mashed root, Huang Miao, stiff seedling, phenomenons such as fertilizer are not lacked of proper care, dewatered, take off to length, tikka, photosynthesis in atrophy second stubble crop; Simultaneously can also improve health, alleviate the harm of herbicide residue, reduce the generation of cardio-cerebrovascular diseases the mankind.Additive of the present invention experiment showed, that through large tracts of land this product effect is fine, and effect of increasing production is obvious.
The present invention compares as follows with other medicament:
| Handle | Usage amount | Atrophy is not long | Dead seedling, mashed root | Huang Miao, stiff seedling | ||||
| The incidence of disease | Disease refers to | Preventive effect % | The incidence of disease | Preventive effect % | The incidence of disease | Preventive effect % | ||
| Medicament of the present invention | 800--1000 times of liquid | 2.3 | 1.4 | 94.0 | 1.6 | 85.7 | 1.1 | 87.4 |
| Compound sodium nitrophenolate | 6000--8000 times of liquid | 5.5 | 3.3 | 85.8 | 5.8 | 37.4 | 5.4 | 34.9 |
| CK | The spray clear water | 38.6 | 23.1 | 11.0 | 8.3 | |||
Experimental results show that, the present invention to because of the long preventive effect of crop atrophy that herbicide residue caused more than 94%, and difference portion is remarkable, be higher than the conventional dose compound sodium nitrophenolate, dead seedling, mashed root and yellow seedling, stiff seedling also there is good preventive effect, can effectively prevent the generation of the multiple diseases that causes because of herbicide residue, protect productive rate more than 27%.Remarkable to crop preventive effects such as soybean, cotton, corn, paddy rice especially, have the excellent popularization using value.
When the present invention was pulvis, during use, 0.07 hectare used one bag, and one bag heavy 40 gram is converted water 20-30 kilogram for one bag.
When the present invention was liquor, every bag 30 gram was converted water 20-30 kilogram for one bag, and 0.07 hectare uses one bag.
