Abstract
The invention discloses a method for preventing and controlling weeds in transplanted rice field. The method mainly comprises the following steps: (1) transplanting in the transplanted rice field, and using chemicals after seven days; (2) mixing application chemicals including pretilachlor emulsion in water and oxadiargyl water dispersant to be uniform by adding water, spraying to fine earth, and broadcasting to the rice field; and (3) carrying out water retention in 3-5cm depth for 4-6 days after applying chemicals. Compared with the prior art, the method for preventing and controlling weeds in transplanted rice field has prominent weed prevention and control effect, can reduce the use of the chemical variety on the basis of the prior art, can save the cost, reduces the environment pollution and is economic and safe.
Description
Technical field
The present invention relates to a kind of transplanting rice weed prevention and controls, belong to agricultural weed prevention and control field.
Background technology
Weeds refer to that growth is the plant being harmful to human survival and space for activities, are generally the wild plant of non-cultivation or the plant that do not hinder the mankind.Plant through naming has more than 30 ten thousand kinds in the whole world, and the plant about more than 8,000 regarding as weeds is planted; The botanical name can found in China's books and periodicals has kind more than 36000, and the plant regarding as weeds has 119 sections kind more than 1200.Weeds have serious impact for plant husbandry, and especially to agricultural development, serious Weed infestation can reduce the output of crops, affects economic development.Weed control refers to carries out manually operated behavior to farmland, woodland ecosystems weeds.Be cover crop, nursery stock, avoid nature to grow plant and fight for it daylight, soil, water and nutrient; The vector exempting from pest spreads disease insect pest; And prevent intoxicating of poisonous weeds etc. and the positive control device taked.
Recent two decades widely uses due to bensulfuron-methyl, and preventive effect declines year by year, declines to the most broadleaved herb preventive effect of paddy field, and the pyrazosulfuron preventive effect that nearly 5 years large area use is also not satisfactory, and easily produces poisoning.The built agent preventive effect of bensulfuron-methyl and Acetochlor, butachlor is all poor, easily produces poisoning.The built agent preventive effect of the third careless amine and the third careless amine and bensulfuron-methyl, pyrazosulfuron cannot meet production requirement.Bing Que Evil humulone single dose easily produces poisoning.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of transplanting rice weed prevention and controls.
Technical scheme: for achieving the above object, the invention provides a kind of transplanting rice weed prevention and controls, it mainly comprises the steps:
(1) transplanting rice field rice transplanting, single administration after 7 days;
(2) drug administration is the third careless amine aqueous emulsion and Bing Que Evil humulone water dispersant, and both add water and mix, and are sprayed on fine earth, spread fertilizer over the fields rice field;
(3) water conservation 3 ~ 5cm after medicine, the time is 4-6 days.
As preferably, the concentration of described third careless amine aqueous emulsion is 45-55% (weight ratio).
Preferred as another kind, the concentration of described Bing Que Evil humulone water dispersant is 75-85% (weight ratio).
Preferred as another kind, by every mu with gauge, the proportioning of described third careless amine aqueous emulsion, the third alkynes Evil humulone water dispersant and fine earth is (60-70) ml:(6-7) g:15kg.
Preferred as another kind, by every mu with gauge, the proportioning of described third careless amine aqueous emulsion, the third alkynes Evil humulone water dispersant and fine earth is 66.7ml:6.25g:15kg
Beneficial effect: compared with prior art, transplanting rice weed prevention and controls of the present invention, prevents and treats all kinds of weeds remarkably productive.And decrease the use of medicament categories on the basis of existing technology, save cost, decreased environmental pollution, more economically safety.
