Description

Oil tea forest land herbicides special
Technical field
The present invention relates to oil tea forest land weeding technique fields, more specifically, it is related to a kind of dedicated weeding in oil tea forest land Agent.
Background technique
Oil tea (Camelliaoleifera) belongs to Theaceae Camellia evergreen shrubs or dungarunga, is that China is distinctive heavy Woody oil tree species are wanted, are the rising industries that China's economy is greatly developed.Existing more than 400 ten thousand hm of camellia oleifera lam area in the whole nation at present2, It is mainly distributed on southern 14 provinces and regions such as Hunan, Jiangxi, Guangxi.In recent years, more than 100 ten thousand hm of oil tea elite seed stand was newly made in the whole nation2, Wherein Hunan Province newly makes more than 200 ten thousand hm of oil tea elite seed stand2.But due to human resources shortage and labor cost it is big Amplitude rises, and huge variation has occurred in the Tending of camellia oleifera lam, and vast enterprise, self-employed tree cultivator begin to use herbicide to replace tradition Artificial weeding foster so that camellia oleifera lam Tending cost is greatly lowered.
But common herbicidal methods effect is bad at present: on the one hand, existing Common Herbicides are difficult to eliminate perennial pernicious Draft then just continues to increase the dosage and frequency of use of herbicide, often destroys ecological environment in this way, influences oil tea forest Normal growth, influence tea-oil tree yield and quality.
Three people such as Hu Fengping, Chen Zhuqing and Sun Jinqiu points out in " oil tea forest land Application of Herbicides ", uses after (a) afforestation Synergist (such as washing powder, diesel oil, dish washing liquid) is not added in glyphosate herbicidal, otherwise, can generate phytotoxicity to tea oil tree；(b) oil tea Tree is the system of taproot, and main root is flourishing, and lateral root fibrous root is smaller, to the stronger herbicide of some residuals, such as sym-trinitrobenzene and substitution Carbamide herbicides can use in oil tea forest land.Wherein substituted urea class includes chlortoluron (chlorotoluron), Li Gu Grand (linuron), daimuron (daimuron), fluometuron (fluometuron), diuron (diuron), isoproturon (isoproturon), cumyluron (cumyluron) etc..
In " camellia oleifera lam chemical weed control effect disquisition " three people such as Yang Shengli, Chen Chuntang and Lu Guoyao carried out glyphosate and Hexazinone prevents and kill off the research of weeds in oil tea forest land, and wherein weeds include awns beanstalk (Dicranopteris pedata), fern (Pteridium aquilinum varlatiusculun) accounts for 80%, remaining is wood (Loropetalun chinense (R.Br) Oliv), Chinese sumac (Rhuschinensis Mill), clerodendrum bungei (Clerodendron bungei Steud), Jin Ying Son (Rosalaevigata Michx) and cogongrass (Imperata cylindrical (L.) Beauv) etc..Studies have shown that grass is sweet Phosphine will reach preferable herbicidal effect to the herbicidal effect significant difference of awns beanstalk, fern, cogongrass etc., and the dosage of glyphosate is very big； The herbicidal effect highest of hexazinone can reach 98.7%, although the herbicidal effect of hexazinone is preferable, which is only It is directed to the weeding research in the oil tea forest land of situation described in text, the weeds type in the oil tea forest land of different regions has larger difference It is different, it is therefore desirable to which that the preventing and kill off for single grass of hexazinone is studied.
Soviet Union ancestor ten thousand has carried out about pernicious in oil tea young growth in " the chemical control test of malignant weed in oil tea young growth " The research of the chemical control of weeds.Studies have shown that glyphosate is applied alone effect poor；Glyphosate mixture (such as: sulfometuronmethyl, second Oxygen toluene fluoride ether) to prevent and kill off awns beanstalk bone, miscellaneous bamboo, shrub effect very poor；Although and hexazinone to Caulis Miscanthis floriduli, miscellaneous bamboo, awns beanstalk bone etc. no The effect of weeds of the same race is extremely significant, but it is poor for the preventive effect of shrub, to reach preferable shrub preventive effect, The dosage of hexazinone is very big.
The patent document that existing data of publication of application is 2016.11.09, application publication number is CN106069397A discloses one Kind oil tea forest land herbicidal methods, the weeding pesticide of application are to reach herbicide with the glyphosate of isopropyl amine salt concentration 41% or agriculture 2-3 grams of 350mL and 2,4-D pulvis (2,4 dichlorophenoxyacetic acid), which mixes well, to be formulated.Although the oil tea forest land weeding side Method herbicidal effect is good and weeding frequency improves, but 2,4- dichlorphenoxyacetic acids have the function of environment incretion interferent, But in " research that environment incretion interferent 2,4 dichlorophenoxyacetic acid, Atrazine interfere sex hormone normal in blood " It points out " interference mechanism that environment incretion interferent may have hormonal balance in blood in hematological system ", and then can push away Determining 2,4 dichlorophenoxyacetic acid has interference effect to hormonal balance in blood.Therefore, the oil tea forest land herbicidal methods need into One step is improved.
Summary of the invention
