Abstract
The invention discloses Chinese fir herbicide, and relates to the agricultural field. According to the Chinese fir herbicide, oxyfluorfen serves as a base material, and quizalofop-p-ethyl or efficient grasses or clethodim or efficient haloxyfop-methyl is matched. Compared with the prior art, due to the fact that the oxyfluorfen is adopted to serve as the base material and the quizalofop-p-ethyl or the efficient grasses or the clethodim or the efficient haloxyfop-methyl is matched, the preventing effect of the herbicide is higher than the preventing effect of an off-season, weeding is wide, gramineous weeds and broadleaf weeds can be prevented and removed at the same time, the usage of pesticide is lowered, the effecting time is shortened, and meanwhile Chinese fir seeds are not damaged. Due to the field application experiment, after the herbicide is sprayed on the Chinese fir seed base covered with weeds for five days, the wild weeds are all withered and dead, the Chinese fir seeds are not influenced, and the problem that when weeding is carried out by common herbicide, a part of Chinese fir is influenced and damaged is avoided.
Description
Technical field
The present invention relates to agricultural technology field, especially a kind of China fir weed killer herbicide.
Background technology
China fir, formal name used at school: Cunninghamia lanceolata (Lamb.) Hook., has another name called: Sha Mu, Sha Shu etc., belong to Coniferales, Taxodiaceae arbor, up to 30 meters, the diameter of a cross-section of a tree trunk 1.3 meters above the ground can reach 2.5-3 rice; Bark taupe; Hibernaculum subcircular, male cone is coniform, female cone Dan Sheng, cone oval, long 2.5-5 centimetre, footpath 3-4 centimetre.
The weeds in Chinese Fir Seedling base occur general, and kind is a lot, and be mainly grassy weed and annual broadleaf weed, weeds and Chinese fir seedling are striven fertilizer and striven water, cause Chinese fir seedling poor growth; Artificial weeding and chemical weed control are herbicidal methods the most frequently used at present, but artificial weeding is not suitable for the China fir of establishing in large scale, and take time and effort also be not easy to management, therefore, for the China fir of establishing in large scale, people generally select China fir weed killer herbicide to carry out chemical weed control.
If so be one of China fir weed killer herbicide, belong to diphenyl ether herbicide, it is mainly by the photosynthesis of interference plant; suppress the generation of ATP; the energy impelling plant for want of required and dead, has good effect to broad leaved weed, but poor to the preventive effect of grassy weed; Trefanocide is also conventional China fir weed killer herbicide, and existing action of contace poison, has systemic action again, and effective to the broad leaved weed of grass family and part small-sized seed, the duration is long, but because it belongs to processing soil treatment agent before bud, invalid to unearthed weeds; Glyphosate also has certain effect to China fir weeding, and it is a kind of inner sucting conduction type broad-spectrum herbicide, can kill 40 Duo Ge section over one hundred kind of weeds, have good control efficiency for grass family, sedge family, but glyphosate is among disturbance at present.
This above-mentioned several herbicides, although have good effect to China fir weeds, also has certain harm to the Chinese Fir Seedling grown, and the Chinese Fir Seedling as understood some when weeding is also therefore withered.
Summary of the invention
Problem to be solved by this invention is to provide a kind of good drug efficacy, delays Weed Resistance, the lasting period is long and Chinese Fir Seedling is had to the China fir weed killer herbicide of good safety.
In order to solve the problems of the technologies described above, scheme of the present invention is: it is base-material with Oxyfluorfen, mixes Quizalotop-ethyl or efficient grass gram or clethodim or haloxyfop-r-methyl.
In technique scheme, scheme can also be more specifically: described Oxyfluorfen and described Quizalotop-ethyl mass ratio are 2:3; Described Oxyfluorfen and described efficient careless gram mass are than being 2:3; Described Oxyfluorfen and described clethodim mass ratio are 2:3; Described Oxyfluorfen and described haloxyfop-r-methyl mass ratio are 2:3.
Oxyfluorfen of the present invention, chemical name is the chloro-4-trifluoromethyl of 2--3'-ethyoxyl-4'-nitrobenzophenone ether, is contact killing type weed killer herbicide; Its activity of weeding is played when there being light.Enter in plant corpus mainly through coleoptile, mesocotyl, less through root absorption, and have denier upwards to be transported by root to enter leaf portion.
Quizalotop-ethyl of the present invention, chemical name: (R)-2-[4-(6-chloroquinoxalin-2-yloxy) phenoxy group] ethyl propionate, be again smart quizalofopethyl, belong to low toxicity herbicide, absorbed by weeds cauline leaf, Bidirectional Conduction up and down in plant corpus, is accumulated in top and intercalary meristematic, T suppression cell fatty acid synthesizes, and makes weeds downright bad.Quizalotop-ethyl is a kind of novel dry land cauline leaf inorganic agent of high selectivity, has the selectivity of height, have good preventive effect to the grassy weed in broad leaf crop field between grassy weed and dicotyledonous crops.Essence quizalofopethyl speed of action is faster, and drug effect is more stable, is not subject to the impact of the environmental conditions such as rainwater temperature and humidity.
Clethodim of the present invention is foliar herbicide, is the ACCase inhibitor of a kind of highly effective and safe, high selectivity, has special efficacy, to dicotyledonous crops safety for most of annual and perennial grassy weed.
Haloxyfop-r-methyl of the present invention, it is a kind of selective herbicide, various grassy weed is prevented and kill off for various broad leaf crop Tanaka, especially to perennial obstinate grassy weeds such as reed, cogongrass, Bermuda grass, there is remarkable preventive effect, to broad leaf crop high safety, effect stability under cryogenic conditions.
Owing to adopting technique scheme, the present invention compared with prior art, has following beneficial effect:
Owing to adopting Oxyfluorfen to be base-material, mix Quizalotop-ethyl or efficient grass gram or clethodim or haloxyfop-r-methyl, the preventive effect of this weed killer herbicide is higher than the preventive effect in dull season, herbicidal spectrum is wide, can effectively prevent and kill off grassy weed and broad leaved weed simultaneously, reduce the usage amount of agricultural chemicals, shorten effective time, do not hurt Chinese Fir Seedling again simultaneously; Tested by Field information, infested with weeds Chinese fir seedling base to be sprayed after this weed killer herbicide 5 days, the whole withered and yellow death ray of wild weeds, Chinese Fir Seedling but meets no danger, and overcomes weed killer herbicide that people commonly use understands some China fir when weeding also therefore withered future trouble.
Embodiment
Below in conjunction with instantiation, the invention will be further described:
Embodiment 1: the preparation of weed killer herbicide
