Adopt the method for chemical ripening dehydration paddy rice can meet the needs of mechanized harvest, reduce yield loss, can not only promote that seed is ripe consistent, improve yield and quality, but also load when can alleviate mechanical harvest.Therefore, the range of application of chemical ripening on crop is further extensive, and technology is also further ripe.
At present, for urging withered composition to mainly contain diquat, paraquat, ethrel etc.Paraquat has very strong oral toxicity to people and animals, and acute poisoning lethality is high, there is no special efficacy antidote at present.Before rice harves, spray paraquat urges withered, and medicine can remain on rice grain, is unfavorable for people and animals' edible safety.Also have a kind of method at present, use diquat to use to urge withered cauline leaf and dry seed the last week in rice harves, but diquat may cause certain underproduction, only be suitable for plum rain season and get the harvest in quickly.
Summary of the invention
Based on this, be necessary to provide a kind of avirulence, can avoid urging the withered rear underproduction and dehydration serious problems break withered composition.
A kind of paddy rice urges withered composition, comprises diquat and growth regulator, and diquat and growth regulator are according to weight ratio 1:1 ~ 10:1 configuration.
Wherein in an embodiment, growth regulator is the one in ethrel and gibberellin.
Wherein in an embodiment, growth regulator is ethrel, and diquat and ethrel are according to weight ratio 1:1 ~ 4:1 configuration.
Wherein in an embodiment, growth regulator is gibberellin, and diquat and gibberellin are according to weight ratio 5:1 ~ 10:1 configuration.
This paddy rice urges withered composition, uses diquat and plant growth adjustment mixture, namely solves diquat and cause the problem of urging the withered rear underproduction, can solve again paddy rice and urge withered de-water problem, reduce airing labour cost, effectively increase economic efficiency.
Embodiment
For the ease of understanding the present invention, will be described more fully the present invention with specific embodiment below.But the present invention can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of this embodiment be make the understanding of disclosure of the present invention more comprehensively thorough.
A kind of paddy rice of the present invention urges withered composition, comprises diquat and growth regulator.Diquat and growth regulator are according to weight ratio 1:1 ~ 10:1 configuration.Growth regulator is the one in ethrel and gibberellin.
By these two kinds of compositions above-mentioned are carried out combination matching, not only can play urge withered dehydration to the paddy rice of results, reduce airing time or without airing, also can not cause the paddy rice underproduction.
The total amount of the active component of composition of the present invention---diquat and biological regulator---can be selected according to concrete factor, to realize desired effect.Described factor mainly refers to formulation, use age and using method etc.
Diquat, biological regulator, solvent are become oil phase, and auxiliary agent and water are mixed into aqueous phase, under agitation oil phase are added aqueous phase and are mixed into aqueous emulsion.
Comparative example one, biological regulator are ethrel, and diquat and ethrel press 1:1 configuration according to aforementioned mixed method.
Comparative example two, biological regulator are ethrel, and diquat and ethrel press 1.5:1 configuration according to aforementioned mixed method.
Comparative example three, biological regulator are ethrel, and diquat and ethrel press 3:1 configuration according to aforementioned mixed method.
Comparative example four, biological regulator are ethrel, and diquat and ethrel press 4:1 configuration according to aforementioned mixed method.
Comparative example five, biological regulator are gibberellin, and diquat and gibberellin press 5:1 configuration according to aforementioned mixed method.
Comparative example six, biological regulator are gibberellin, and diquat and gibberellin press 7:1 configuration according to aforementioned mixed method.
Comparative example seven, biological regulator are gibberellin, and diquat and gibberellin press 10:1 configuration according to aforementioned mixed method.
Comparative examples one, be used alone ethrel.
Comparative examples two, be used alone gibberellin.
By the composition of above-mentioned comparative example and comparative examples, be a large group separately, seven days groups, ten days groups and 15 days groups, three experimental group are divided again in every large group group, each experimental group is according to every mu of 200 milliliters of compositions and be watered the consumption of 40 kilograms, seven days groups are gathered in the crops the first seven sky in paddy rice ripening stage and are sprayed, ten days groups are gathered in the crops in paddy rice ripening stage and are sprayed for front ten days, 15 days groups are gathered in the crops in paddy rice ripening stage and are sprayed for first 15 days, each large group complete test after to urging the water content of withered rate and grain measure and compare, data are as follows:
From contrast experiment's data, seven days groups urge withered effect entirety to be better than ten days groups and 15 days groups, can think that paddy rice ripening stage, to carry out spraying be better suited in the first seven sky.
Contrast the data of two comparative examples and seven comparative examples, that can see comparative examples urges withered effect entirety not as comparative example, and when water content is higher suitable only with comparative example of thousand kernel weight.
It seems from the data of seven comparative examples, the effect entirety of ethrel is better than gibberellin, ethrel urge withered better effects if, and can higher thousand kernel weight be kept.
Visible, the combinationally using of diquat and biological regulator is better than biological regulator and is used alone.Biological regulator is optimum with ethrel, especially diquat: ethrel (1.5:1) proportioning is best, and gibberellin takes second place.
Diquat chemical name: 1,1'-ethylidene-2,2'-bipyridyl dibromo salt, it can the electron transmission of inhibited photosynthesis after being absorbed by green plants, the Bipyridine compound of reducing state is under photoinduction, oxidized very soon when aerobic exists, and forms active hydrogen peroxide, the accumulation of this material makes plant cell film destroy, withered and yellow by medicine position.Can be used as spermatophyte desiccant; Also can be used for the crops such as potato, cotton, soybean, corn, Chinese sorghum, flax, sunflower and urge withered dose; When processing ripe crop, green portion and the weeds of remnants are dried-up rapidly, and can gather in ahead of time, loss of seeds is less.Ethrel chemical name: 2-chloroethyl phosphoric acid, soluble in water, methyl alcohol, acetone, ethylene glycol, propane diols, be slightly soluble in toluene, be insoluble to benzinum.Be plant growth regulator, there is plant hormone and promote milk expression, hasting of maturity, come off, the physiological effect of old and feeble and Accelerate bloom.Under certain condition, ethrel not only self can discharge ethene, and plant can also be induced to produce ethene.Gibberellin refer to there is gibbane skeleton, the general name of the compounds that can irritate cell division and elongation, extensively exist in plant corpus, crop growth can be promoted, make it premature ripening, improve output, improve quality, fruit growth can also be stimulated, improve the fruiting rate of fruit, have significant effect of increasing production to paddy rice, cotton, vegetables, melon and fruit, green manure etc.To sum up, by combinationally using diquat and biological regulator, not only can play urge withered dehydration to the paddy rice of results, reduce airing time or without airing, also can not cause the paddy rice underproduction.
