Abstract
The present invention relates to a maturing agent for cotton, which is an ethephon-paraquat aqueous solution prepared by compounding the plant growth regulator of ethephon (2-chloroethyl phosphonic acid), the contact poisoning type herbicide of paraquat (the cation salt of 1, 1'-dimethyl-4, 4'-bipyridine) and water in a certain proportion, wherein the components with the proportioning rangescomprise 10% to 50% of the original chemical of the ethephon, 3% to 20% of the original chemical of the paraquat, and water as the rest, and the summation of the weight percentages of the components is 100%. The present invention has fast maturing effect and low cost, the grade of cotton can be improved, and both production and income can be increased.
Description
The present invention relates to a kind of cotton ripener that cotton plays dematuration that is mainly used in.
It is one of important step of Cotton Production middle and later periods management that optimum period accelerates the ripening, and the cotton ripener that generally uses is based on the plant growth regulator ethrel at present.Ethrel has another name called an examination spirit.Its English name: ethephon; Chemical name: 2-chloroethyl phosphoric acid; Chemical structural formula:
Molecular formula: C2H6O3Clp; Relative molecular weight (by international relative atomic mass in 1993) 144.5; Fusing point: 74～75 ℃.Soluble in water, methyl alcohol, ethanol are insoluble in benzene and dichloroethylene.Ethrel is very stable in the highly acid medium, but decomposites ethene very soon in pH value＞4 media.The pH value of the general plant cell of cause is all more than 4, and ethrel enters in the plant corpus through blade, bark, the fruits and seeds of plant, is transmitted to the position of effect then, just discharges ethene, plays the effect that promotes fruit maturation and leaf abscission.The ethrel list agent effect of accelerating the ripening is slower, and stubble sowing behind the cotton wheat crop rotation area is had certain influence, and cost higher (about every mu of consumption 300 grams, 1.8 ten thousand yuan/ton of unit prices close about 5 yuan/mu).
The object of the present invention is to provide that a kind of effect of accelerating the ripening is fast, cost is low, can improve cotton grade not only can increasing both production and income and but also do not influence the new cotton ripener of cotton development.
The present invention is achieved in that a kind of ethrel paraquat aqua, it is with plant growth regulator ethrel (2-chloroethyl phosphoric acid) and contact killing type herbicides paraquat (1,1 '-dimethyl-4,4 ' one bipyridine cation salt) and the composite by a certain percentage ethrel paraquat aqua of making of water, the ratio range of each component is: the former medicine 10～50% of ethrel, the former medicine 3～20% of paraquat, all the other are water, the summation of each component is 100%.
Compare with existing ethrel list agent ripener, the present invention adopts plant growth regulator ethrel and the composite ethrel paraquat aqua of making of contact killing type herbicides paraquat, on probation and the tests of pesticide effectiveness through many areas, this product accelerate the ripening on cotton that fallen leaves are fast, the cracking blow-of-cottons early, to increase before the frost flower and the effect of raising grade obvious.And can reduce young bell and come off, it is heavy to reduce the bell shell, increases illumination, avoids mashed bell, improves output of cotton, reaches the effect of increasing both production and income.And consumption few (about every mu 80 gram, only 1/3 of ethrel, toxicity is little, and is easy to use, use cost low (close about 3 yuan/mu), only about 60% of ethrel.It is a kind of more satisfactory cotton ripener.
Below in conjunction with embodiment the present invention is made a detailed description:
Ethrel paraquat aqua of the present invention by the former medicine of ethrel (2-chloroethyl phosphoric acid), the former medicine of paraquat (1,1 '-dimethyl-4,4 '-the bipyridyl ion salt), auxiliary agent and water by a certain percentage, stir the composite greyish black aqueous solution that forms under given conditions.More stable at acid medium (pH value＜3), meet alkali and then decompose easily.Soluble in water, be insoluble in organic solvent.Its component ratio range is: the former medicine 10～50% of ethrel (weight), the former medicine 3～20% of paraquat (weight), auxiliary agent 5～15% (weight); Water 20～80% (weight); The each component summation is 100% (weight).The proportioning of the sharp former medicine of therein ethylene, the former medicine of paraquat also can be 20～30% and 5～10%.Be preferably 22～28% and 6～9%.Auxiliary agent is a surfactant.Preparation after composite proves that through cotton field control effectiveness test for many years the disleave rate of its effect of accelerating the ripening, cotton, blow-of-cottons rate, bell heavily reach fiber length and be significantly improved, and cost is low, has reached the purpose that improves grade, increasing both production and income simultaneously.
Production technology summary:, mix in the enamel reaction pot with the input of the ethrel after paraquat, auxiliary agent, water and fusion belt stirrer then and stir evenly discharging then, finished product metering packing earlier with the former medicine heating and melting of ethrel.
Lift three example its proportioning of explanation and production processes below:
Example 1: at first, get the former medicine 255kg heating of ethrel melting; Then, mix stirring evenly in the enamel reaction pot with the input of the ethrel after paraquat 365kg, water 1380kg and fusion belt stirrer, discharging, cooling back packing.
Example 2: at first, get the former medicine 300kg of ethrel heating and melting; Then, the ethrel of paraquat 50kg, auxiliary agent 50kg, water 500kg and fusion is dropped into mixes in the enamel reaction pot of belt stirrer and stir evenly, discharging, pack the cooling back.
Example 3; At first, get the former medicine 250kg of ethrel heating and melting; Then, the ethrel of paraquat 80kg, auxiliary agent 100kg, water 570kg and fusion is dropped into mixes in the enamel reaction pot of belt stirrer and stir evenly, discharging, pack the cooling back.
