Abstract
The invention provides a low-amount synergistic weeding compound agent for paddy field transplantation and application thereof. An application method of the low-amount synergistic weeding compound agent comprises the following steps: directly mixing the following effective components uniformly according to per hectare: 3.6-8.1 g of a plant growth regulator, 13.5-645 g of a weed killer, and 200-1000 g of kieselguhr, and spreading the mixture over a paddy field 5-10 days after the paddy field transplantation. According to the invention, on the basis of the regulation principle of the plant growth regulator and through the utilization of the characteristics of low dosage and no toxicity or low toxicity of the plant growth regulator, the plant growth regulator is compounded with the weed killer, so that the safety coefficient of the weed killer can be increased, the harmful degree of the weed killer to crops is reduced to the minimum, the crop growth balance can be regulated, and the control and elimination function on weeds can be superposed, and the control efficiency is improved; besides, the dosage of the weed killer is reduced, and the paddy rice yield increase and income increase can be guaranteed.
Description
Technical field
The invention belongs to Rice Cropping technical field, particularly relate to a kind of transplanting rice field and subtract medicine Herbicidal synergistic built agent and application thereof.
Background technology
In Rice Cropping process, need timing to remove weeds in field, at present, the removing of weeds is all by directly carrying out at field spraying herbicide.Although the removal of weed killer herbicide to weeds has good effect, because Weed Resistance constantly strengthens, weed killer herbicide consumption constantly increases, and brings residual and pollutes.Due to himself property of medicine of weed killer herbicide, when residue of pesticide reach a certain amount of in soil, inevitably also can produce certain harm to rear stubble crops.If reduce this harm by reducing weed killer herbicide consumption, there will be again the problem that herbicidal effect is undesirable.
Summary of the invention
The object of the present invention is to provide a kind of transplanting rice field to subtract medicine Herbicidal synergistic built agent and application thereof, be intended to solve existing weed killer herbicide can produce certain harm in weeding process problem to paddy rice.
The present invention is achieved in that a kind of transplanting rice field subtracts medicine Herbicidal synergistic built agent, comprises following by each component of mass parts:
Plant adjustment 3.6 ~ 8.1 parts,
Weed killer herbicide 13.5 ~ 645 parts,
200 ~ 1000 parts, diatomite;
Wherein, described in plant adjustment and comprise planting and adjust A and planting and adjust B, described in plant and adjust that A is brassin lactones, one or several in CPPU, nucleotide.
Describedly plant that to adjust B be one or several in compound sodium nitrophenolate, heteroauxin and methyl α-naphthyl acetate.
Preferably, described weed killer herbicide be one in prometryn, 2 first 4 chlorine sodium, bensulfuron-methyl, mefenacet, Oxyfluorfen and butachlor, two kinds or three kinds.
Preferably, described in plant adjust for plant adjust A, described weed killer herbicide is mefenacet or prometryn; Wherein, mefenacet is 50% of described built agent Chinese medicine effective ingredient consumption, 40% of built agent Chinese medicine effective ingredient consumption described in prometryn.
Invention further provides above-mentioned transplanting rice field and subtract the application of medicine Herbicidal synergistic built agent in Rice Cropping.
Preferably, above-mentioned transplanting rice field subtracts the application of medicine Herbicidal synergistic built agent in Rice Cropping, this application method comprises the following steps: plant adjustment 3.6 ~ 8.1 grams by per hectare active ingredient, weed killer herbicide 13.5 ~ 645 grams, 200 ~ 1000 grams, diatomite is mixed directly, within 5 ~ 10 days after transplanting rice, spread fertilizer over the fields in rice field.
The present invention overcomes the deficiencies in the prior art, a kind of transplanting rice field is provided to subtract medicine Herbicidal synergistic built agent and application thereof, by planting adjustment 3.6 ~ 8.1 grams by per hectare active ingredient, weed killer herbicide 13.5 ~ 645 grams, 200 ~ 1000 grams, diatomite is mixed directly, and within 5 ~ 10 days after transplanting rice, spreads fertilizer over the fields in rice field.The present invention plants the adjustment principle of adjustment according to some, utilize the feature of planting low, the nontoxic low toxicity of adjustment consumption, with mixture of herbicides, diatomite plays the effect of certain slowly-releasing drug effect, can not only improve the safety coefficient of weed killer herbicide, and the detrimental extent of weed killer herbicide to crops is dropped to minimum, and can balance by regulating crop growth, can superpose and function is prevented and kill off to weeds, improve preventive effect, reduce weed killer herbicide consumption simultaneously, ensure that increasing production of rice increases income again.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Select Yunnan Guanyuan rice district transplanting rice field 2 points, 5 ~ 20 mu, every experimental tests field, as project research field.Select weed killer herbicide Representative Cultivars prometryn, 2 first 4 chlorine sodium, bensulfuron-methyl, mefenacet, Oxyfluorfen, butachlor that rice district, plateau is the most frequently used, adjust A and planting to adjust B composite with planting, carry out prevention and control weeds drug effect, increasing production of rice test, screening optimum formula, result of the test is as shown in following table 1 ~ 2:
Table 1 weed killer herbicide adjusts mixture control careless synergism test result statistical form with planting
Table 2 weed killer herbicide adjusts mixture control careless synergism test result statistical form with planting
As can be seen from table 1 ~ 2, the weed killer herbicide kind that rice district, plateau uses in a large number is composite suitable plants adjustment, has the effect reducing dosage, increase production and improve productivity.When reducing weed killer herbicide consumption 5% ~ 10%, still herbicidal effect and rice yield can be ensured; Adjusting A and 40% prometryn+plant with 50% mefenacet+plant, to adjust the kind proportioning effect of A best, plants to adjust A and the drug effect of mixture of herbicides and be better than to plant and adjust B, and built agent field test effect well, can Demonstration Application further.
Compared to the shortcoming and defect of prior art, the present invention has following beneficial effect: the present invention plants the adjustment principle of adjustment according to some, utilize the feature of planting low, the nontoxic low toxicity of adjustment consumption, with mixture of herbicides, the safety coefficient of weed killer herbicide can not only be improved, the detrimental extent of weed killer herbicide to crops is dropped to minimum, and can balance by regulating crop growth, can superpose and function is prevented and kill off to weeds, improve preventive effect, reduce weed killer herbicide consumption simultaneously, ensure that increasing production of rice increases income again.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
