Abstract
A herbicide for paddy field in order to promote growth of rice and increase yield contains herbiciding chemical (2-80%) and humic acid or humates (20-98%), and features high herbiciding effect.
Description
The present invention relates to herbicide for paddy field, in particular for the humic acid of paddy field management of weeds and the compound of its esters and paddy field weed-killer chemicals.
China region is wide, because weather cold, spring, ground temperature, water temperature were lower, and the paddy rice early development is had adverse effect in the north, high latitude cold temperate climate district especially, and the crop growth phase is short, and heat resources lacks, and damages to plants caused by sudden drop in temperature threatening paddy growth.
Purpose of the present invention promptly provides a kind of herbicide for paddy field, and it can make the water temperature in paddy field raise on the basis that does not reduce herbicidal effect, alleviates the chilling injury influence, thereby makes the wet crop volume increase.
For realizing this purpose, technical scheme of the present invention is as follows:
A kind of herbicide for paddy field is characterized in that: add the filler humic acid in the weeding chemicals, wherein weeding chemicals content is 2%～80%, and humic acid content is 20%～98%, and concrete proportioning humic acid content when using is no less than 200 for every mu and restrains.
A kind of herbicide for paddy field, it is characterized in that: in the weeding chemicals, add filler humic acid salt, wherein weeding chemicals content is 2%～80%, and humic acid salt content is 20%～98%, and concrete proportioning humic acid salt content when using is no less than 200 for every mu and restrains.
Described humic acid is humic acid, fulvic acid, humic acid, fulvic acid.
Cash metal and cash earth metal salt and ammonium salts such as the sylvite that described humic acid salt is a humic acid, sodium salt.
Described weeding chemicals is a kind of of aryloxy carboxylic acid, amide-type, carbamates, ureas, sulfonylurea, heterocyclic, organic phosphates, cyclohexenone analog etc. or several.
After adopting such scheme, of the present invention is that the herbicide for paddy field of filler can make the water temperature of paddy field raise 2～3 ℃ with humic acid and its esters, and the effect of management of weeds is still better.Water temperature improves on the one hand, can alleviate the chilling injury influence, promotes the crop root of hair, and it is fast to turn green, and it is healthy and strong to grow up; Do not have weeds on the other hand, crop growing state is strong, and it is fast many to tiller, and it is vigorous to grow, thereby can obtain high yield, stable yields, finally reaches volume increase.
The present invention will be described in detail below in conjunction with specific embodiment.
Herbicide for paddy field of the present invention is to add filler humic acid and its esters in the weeding chemicals, wherein weeding chemicals content is 2%～80%, humic acid content is 20%～98%, and concrete proportioning humic acid and its esters content when using are no less than 200 for every mu and restrain.
Humic acid is humic acid, fulvic acid, humic acid, fulvic acid.The humic acid salt is cash metal and cash earth metal salt and ammonium salts such as the sylvite, sodium of humic acid, fulvic acid, humic acid, fulvic acid.Wherein best with humic acid and its esters effect.
Can aryloxy carboxylic acid be arranged with the composite weeding chemicals of humic acid and its esters among the present invention, amide-type, carbamates, ureas, sulfonylurea, heterocyclic, organic phosphates, weeding chemicals such as cyclohexenone analog, they are clomeprops, naproanilide, three ethoxies grass ether, the third careless amine, kecaoan, butachlor, mefenacet, bromobutide, Amex820, grass reaches the sky, tiocarbazil, dimepiperate, the east grass is red, pyributicarb, esprocarb, fluorine sulphur is grand, the benzyl ethyl methyl, metsulfuron-methyl, pyrazosulfuron, pyrazolate, benzofenap, pyrazoxyfen, the pyridine of fluorine sulphur grass, cinmethylin, dichloro quinolinic acid, symetryne Evil humulone, prometryn, TCE-styrene, 2 first, 4 chlorine, bentazone, Stam F-34 etc.Humic acid and its esters as filler both can with above-mentioned chemical weed control compound in a kind of composite, also can be composite with several, all can realize the present invention.
The consumption of humic acid and its esters has a significant effect to water temperature.Along with the increase of humic acid and its esters consumption, water darkens, and caloric receptivity increases, and water temperature rising amplitude strengthens.The concrete proportioning of herbicide for paddy field of the present invention humic acid and its esters content when using are no less than 200 grams for every mu, and optimal value is more than every mu 400 gram.
Example: humate aqueous temperatureization:
Use the 1000ml volumetric flask, humic acid sodium be made into the sodium humate aqueous solution of variable concentrations, be put into the outdoor solar irradiation test of carrying out:
Subordinate list 1 is the exposure experiments to light data.
Embodiment 1:
Selection fertility uniformity, the field piece that the weeds kind is many, generating capacity is big are done the experimental field.The dispenser field keeps the 5cm depth of water, and after this not irrigation and drainage in 5 days behind the medicine recover normal.
With the sodium humate is 5% dichloro quinolinic acid soluble powder of filler, and control group is that 50% dichloro quinolinic acid soluble powder is carried out the transplanting rice weed preventing iron test.
5% dichloro quinolinic acid soluble powder sees attached list 2 to preventing and killing weeds in rice field effect (behind the medicine 30 days).
5% dichloro quinolinic acid soluble powder (sodium humate filler) is surveyed to produce in transplanting rice weed weeding test and be the results are shown in subordinate list 3.
Embodiment 2:
5.5% benzene benzyl (mefenacet, benzyl ethyl methyl) but wet-milling (wherein filler is a sodium humate).But control group 55% benzene benzyl wet-milling.All dispensers behind the rice transplanting kept the depth of water 3-4cm7 days.
But 5.5% benzene benzyl wet-milling is prevented and kill off the effect (behind the medicine 30 days) of transplanting rice field weed and is seen attached list 4.
5.5% benzene benzyl transplanting rice field weed preventing iron test is surveyed to produce and be the results are shown in subordinate list 5.
Embodiment 3:
But 5% fourth second benzyl wet-milling (is filler with the sodium humate)
Control group: 60% fourth second benzyl (butachlor, Acetochlor, benzyl ethyl methyl) suspending agent, 60% butachlor ec, but 10% Nongdeshi wet-milling
But the effect of 5% fourth second benzyl wet-milling control weeds in paddy field sees attached list 6.
But 5% fourth second benzyl wet-milling sees attached list 7 to the influence of fertility and output.Subordinate list 1: exposure experiments to light data
