Abstract
The invention discloses a ripening composition containing thidiazuron and paraquat, and its preparation method and application. The ripening composition is characterized by containing thidiazuron, paraquat and other auxiliary agents, wherein a weight ratio of thidiazuron to paraquat is in a range of (30: 1) to (1: 50). The ripening composition can be utilized for ripening cotton. The ripening composition has the advantages of safety, environmentally friendly characteristics, low cost and good effects. A result of a pharmacodynamic test in a field shows that the ripening composition has obvious ripening effects and yield increasing effects.
Description
Technical field
The invention belongs to field of agrochemicals, relate to the composite of two kinds of agricultural compounds, refer in particular to that Thidiazuron and paraquat are composite to be used for composition and the application thereof that cotton is accelerated the ripening.
Background technology
Thidiazuron:
The colorless and odorless crystal, fusing point 210.5-212.5 ℃ (decomposition), vapour pressure 4nPa (25 ℃ of blue Mil's methods), Kow59 (pH73), solvability water 31mg/L (pH7,25 ℃), hexane 0.002, methyl alcohol 4.20, carrene 0.003, toluene 0.400, acetone 6.67, ethyl acetate 1.1 (g/L, 20 ℃), see that the light time easily changes into optical isomer, stable under the pH5-9 room temperature, (14 days 54 ℃) are undecomposed in quickening the shelf-stable Journal of Sex Research.Be a plant growth regulators, on cotton planting, make defoliant and use.After being absorbed by the cotton plant blade, can impel chorista between petiole and the stem to form naturally early and fall leaves, help machinery and receive cotton and also can make cotton harvesting shift to an earlier date about 10 days, help to improve cotton grade.
Paraquat:
Quick-acting contact killing type steriland herbicides, after bipyridine cation is absorbed by plant leaf rapidly, in chlorenchyma, be reduced into the bipyridyl free radical by photosynthetic and respiration, make water and oxygen in the leaf texture form hydrogen peroxide and peroxy radical through autooxidation again, this class material is extremely strong to chloroplast tunic destructive power, make photosynthesis and chlorophyll synthesize very fast termination, blade behind the medicine and promptly to be begun the variable color of being injured in 2-3 hour, paraquat all has very strong destruction to the chlorenchyma of unifacial leaf and dicotyledon, but do not have conduction, the medicine position is injured.Can not penetrate the bark after the bolt materialization.Once with after soil contacts, promptly be adsorbed passivation.Weeds have orthogenesis after can not damaging seed hiding in plant root and the soil thereby dispenser.

Embodiment: the effect assessment of Thidiazuron, the composite ripener of paraquat
1 materials and methods
1.1 reagent agent
Former medicine: Thidiazuron (content, 98% Jiangsu Youshi Chemical Co., Ltd).Paraquat (content, 91%, the many really Fine Chemical Co., Ltd in Hengshui)
1.2 for the examination target
Cotton: when preserving cotton, moisture and temperature can not be too high, otherwise just are easy to go bad, and vitality completely loses in some months, preserves so will be placed under the low temperature drying condition.Get cotton seed of the same size and soak, because cottonseed kind skin is tough and tensile, and there is one deck short flannel on the surface, if dry seed is live, presoaking and germinating helps broadcasting full stand, and the precocity of early emerging.With soaked in cold water 24 hours, pull two hours out, be spread out in two, three cun thick basking seeds on the filter paper, shine when the seed hair bleaches, build vernalization with Polypropylence Sheet.
2 experimental designs
2.1 dosage setting
Get Thidiazuron, two kinds of former medicines of paraquat, add dimethyl formamide at 23 ℃ then, make former medicine dissolving.Add 0.1% tween then. according to 1: 3.51: 51: 71: 91: 121: 15 several proportionings are made into 35% aqua.
2.2 test method
2.2.1 Toxicity Determination test
In the culture dish that 15 are placed on cottonseed D=9CM, add the soup of the above-mentioned different proportionings of 5ML then, each proportioning is established 4 repetitions, calculates germination rate at last.
Table 1 Thidiazuron paraquat aqua is to cottonseed germination test influential effect
Learn the EC of Thidiazuron and paraquat by single agent Toxicity Determination test
50Be respectively 20ug/ml and 25ug/ml/.Calculate the virulence equation such as the following table of each proportioning thus:
Table 2 Thidiazuron paraquat aqua is to the virulence regression equation of seed germination
Can reach a conclusion from the Toxicity Determination test, though the germination rate to seed after composite has certain inhibitory action, the effect that improves with virulence is lower, and inhibitory action is little, can reach a conclusion: the medicament of 7: 1 these proportionings is less to the influence of the germination rate of seed, after reaching a conclusion from Toxicity Determination test, these several proportionings are tested big Tanaka, to the influence of the effect of accelerating the ripening of comparison cotton.
