Description
Technical field
The invention belongs to agricultural technology fields, and in particular to a kind of corn field Synergistic herbicide compositions and its application.
Background technique
China is corn major producing country in the world, about 300,000,000 mu of long-term cultivated area or so, Huang-Huai-Hai be China most
Big Summer Maize growing area.Planting type is mostly two-cropping for wheat and corn in one year, and planting form is largely interplanting or iron
Stubble sowing.Corn field main weeds raw gramineae weed one year, such as: barnyard grass, herba setariae viridis, herba digitariae, wild avena sativa, herba eleusines indicae
Deng；Annual broadleaf weed, such as: oak-leaved goosefeet dish, Amaranthus retroflexus, piemarker, purslane, field bindweed, dayflower, herba eragrostidis pilosae, setaria viridis,
Iron amaranth grass, cottonsedge-like thistle herb, black nightshade, sowthistle, field thistle, rhizome of nutgrass flatsedge etc.；The harm of weeds can cause 1~2 one-tenth of the corn underproduction, sternly
3~5 one-tenth of underproduction when weight.
Corn field weed vitality is extremely vigorous, and seed can still germinate for 20 years in soil, as the rhizome of nutgrass flatsedge, Chenopodiaceae, knotweed,
Purslane, field bindweed etc..Weeds usually have the characteristics that mature early, irregular, segmentation emergence, are unfavorable for preventing and treating, and very much
Weeds can wake up from death, especially perennial weeds, such as purslane is shone 3 days after manually pulling out in field, and rainy season still may be used
Restoration ecosystem.In addition, weeds also have a surprising fertility, the solid number of most weeds is several times of crop, several hundred
Even up to ten thousand times again.There are about 220,000 seeds for every plant of herba digitariae according to investigations, it is seen that its fertility it is powerful.
Chemical method weeding is one of the main means for agriculturally controlling weeds.In recent years, due to some herbicide kinds
Large area is used alone, and has caused a lot of weeds to develop drug resistance.Meanwhile grass phase is complicated when weeds generation, grass family is miscellaneous
The mixed life of grass, broadleaf weeds, nutgrass flatsedge multiclass weeds, single variety herbicide can be shown using not can solve farmland weed
Defects and limitations in a certain respect.
Different types of herbicide mixture, has that herbicidal spectrum is wide, promotes actual effect, delays herbicide resistance, is time saving
Saving of labor's advantage.By the screening of formulation of pesticide, practical control efficiency can be effectively improved, dosage is reduced, reduces cost, delay
The generation of disease, worm, crop smothering drug resistance is an important means of comprehensive agricultural management.
Nicosulfuron also known as cigarette sulphur is grand, Yu Nongle, belongs to the absorbability cauline leaf process herbicide of sulfonylurea, can be miscellaneous
Grass blade leaf and root absorption, then conduct in plant, cause sensitive plant growth retardation, cauline leaf chlorisis, gradually withered, and one
As in the case of death in 20~25 days, but longer time is needed to certain perennial weeds in the lower situation of temperature.4 after bud
The good drug efficacy being administered before the leaf phase, the drug effect decline being administered when seedling is big.After the medical instrument has activity of weeding before bud, but activity is compared with bud
It is low.
Mesotrione, one kind is able to suppress before the bud of medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dual oxide enzyme (HPPD) and wide spectrum selects after seedling
Selecting property herbicide can effectively prevent main broadleaved herb and some gramineae weeds.The mesotrione suspending agent pair of 100 grams per liters
Corn field annual broadleaf weed and part gramineae weed such as piemarker, three-coloured amaranth, Chenopodiaceae, knotweed, barnyard grass, herba digitariae etc. have preferable prevention and treatment
Effect.However it is poor to acalypha copperleaf and some gramineae weed control efficiency.Dosage is 105~150g (effective component)/ha
(being converted into 100 grams per liter mesotrione suspending agent commodity amounts is 70~100mL/ mus.General spouting liquid is 15~30L/ mus).It uses
Method is spraying for cauline leaf.The corn in one season uses 1 time, to corn safety under recommended dose.
Atrazine, chemical name are the chloro- 4- ethylamino- -6- isopropylamino -1,3,5-triazines of 2-.Atrazine is in selectivity
Inhale conduction type seedling before, herbicide after seedling, based on root absorption, cauline leaf absorb seldom, be transmitted to rapidly plant meristem and
Leaf portion, interference photosynthesis keep weeds lethal.In the resistance crops body such as corn, atrazine resolves into non-poisonous material by corn ketolase
Matter, thus to seeding corn and other crops safety.The lasting period of atrazine is longer, broad weed-killing spectrum, for preventing and kill off corn field annual grassy weeds,
It is especially preferable to the preventive effect of corn field broadleaf weeds.Atrazine is easily eluted by rainwater to soil deeper, to certain deep roots
Grass is also effective, but is easy to produce phytotoxicity.When weeds generation density is higher or plant is larger, it is difficult to thoroughly kill weeds.
Thifensulfuronmethyl belongs to selective herbicide after inner sucting conduction type seedling, is branched-chain amino acid synthetic inhibitor, can inhibit
The biosynthesis of valine, leucine, isoleucine prevents cell division, sensitive crop is made to stop growing.It is mainly used for preventing and kill off
Cereal crop wheat, barley, oat, corn field broadleaf weeds, such as Amaranthus retroflexus, purslane, Descurainia sophia, shepherd's purse, pig
Hair dish, clearvers, Veronica, ox chickweed etc., however it is invalid to field thistle, field bindweed and dogstail etc..
Brassin lactones class compound is novel sterols plant endogenous hormones, and bioactivity is higher, universally present in
In the organs such as pollen, seed, stem and the leaf of plant, it has been found that brassin lactones class compound 18.Brassin lactones class chemical combination
Object can be absorbed via the leaf, stem, root of plant, then be transmitted to the position worked, and having makes plant cell division and extended
Double action can promote well developed root system, enhance the absorption to liquid manure, promote plant growth, improve chlorophyll content, enhance photosynthetic
Effect, promotion fertilization, flower and fruit protecting promote Fruit, increase mass of 1000 kernel, improve the quality of crop, and enhancing crop cold resistance resists
The resistance such as drought, salt resistance alkali mitigate phytotoxicity, increase disease resistance.It is dissolved in the organic solvents such as methanol, ethyl alcohol, ether, chloroform, indissoluble
Yu Shui.The significant effects such as volume increase, upgrading, disease-resistant, degeneration-resistant, reparation, solution phytotoxicity, drop residual, synergy are above shown in the application of agricultural
Fruit is suitable for cereal crops, industrial crops, vegetables and fruit etc., is to develop to subtract to apply synergy, highly efficient farming to provide greater and better yields not
It can the excellent products that obtained more.The concentration for the treatment of of brassin lactones is extremely low, and usual 10-1~10-5Mg/L can show powerful physiology
Activity.
Corn field herbicide is limited by crop safety at present, and degrass spectrum is also limited, and a kind of herbicide single dose is used alone
Cannot completely effectively control the generation of corn field weed, furthermore some herbicides because the water-soluble big or field lasting period is too long,
Dosage is big or application unevenly be easy to cause the residual hazard to this season crop or succession crop.
