Abstract
The invention provides a plant growth regulator for improving upper leaf enlargement, nicotine reduction and potassium increase after topping. The plant growth regulator is prepared by taking by weight, 0.001-99.990% of gibberellic acid, 0.001-99.990% of heteroauxin, malonic acid, 0.001-99.990% of 2,4-d, 0.001-99.990% of dimethylformamide, 0.001-99.990% of nonylphenol polyoxyethylene ether and 0.001-99.990% of cyclohexanone, mixing the raw materials with uniformly stirring to prepare mixed solution and mixing, by weight, 60-70% of the mixed solution and 30-40% of potassium dihydrogen phosphate buffer solution with uniform stirring. By spraying the plant growth regulator to upper tobacco leaves, the growth period of a tobacco field is shortened, upper tobacco leaf enlargement, nicotine reduction and potassium increase can be promoted, tobacco leaf output is increased, and ashy tobacco leaves after baking of the upper tobacco leaves can be decreased. Besides, the tobacco leaves are slightly loose in structure, slightly dark, slightly high in gloss and sufficient in aroma, a single upper leaf is slightly heavy, the proportion of high-quality and medium-quality tobaccos is effectively increased, and accordingly economic income of tobacco growers is increased.
Description
Technical field
The invention belongs to technical field of pesticide, particularly a kind of rear upper leaf that improves of pinching hacks and falls the plant growth regulator that alkali increases potassium.
Background technology
Upper tobacco leaf, availability is not high to be one of Main Problems in the cured tobacco production of current National Tobacco Leaves producing region, because it is strong that upper tobacco leaf is in illumination, under the draughty condition, its dry-matter accumulation is many, hack bad, its blade is narrow and partially thick, leaf cell is tight, and the institutional framework densification is stiff, moisture content less, ripe slow, and the cured tobacco leaf dust is many, color is deeply dark, nicotine, starch, protein content is too high, and reducing sugar and sugared alkali are on the low side, tobacco aroma quality is poor, perfume quantity is not enough, it is strong etc. that excitant is crossed, therefore cause industrial applicability poor, bring difficulty to cigarette industry, thereby restricted the market management of upper tobacco leaf.
Summary of the invention
Purpose of the present invention, be the problems that exist in sum upper tobacco leaf, a kind of flue-cured tobacco rear cigarette strain apical dominance of pinching of keeping is provided, reducing the mineral nutrients such as blade potassium, calcium shifts, can promote leaf tissue cell development and cigarette strain upper leaf to hack, promote the upper tobacco leaf quality, increase the rear plant growth regulator that upper leaf hacked, fell alkali, increases potassium that improves of pinching of output.
Plant growth regulator of the present invention is got gibberellic acid, heteroauxin, malonic acid, 2, and 4-D, dimethyl formamide, polyoxyethylene nonylphenol ether, cyclohexanone, potassium dihydrogen phosphate buffer solution are raw material, and through formulated.
Gibberellic acid, English common name gibberellic acid has another name called gibberellin, is the solid shape.It is mainly synthetic by the tender cambium of Young Plant, is the important substance of keeping, promote that plant tip growth is grown.Cigarette strain apical dominance after it can be kept flue-cured tobacco and pinches reduces the transfer of the mineral nutrients such as blade potassium, calcium, promotes growth and the cigarette strain upper leaf of leaf tissue cell to hack, and promotes the upper tobacco leaf quality, increases output, reduces alkalinity, improves potassium content.
Heteroauxin is a kind of organic matter, belongs to Benzazole compounds, is the solid shape.It is ubiquitous Endogenous auxin in a kind of plant corpus, is a kind of hormone of coordinate plant growth and growth.
Malonic acid is the solid shape.It is the intermediate of bactericide Isoprothiolane, also is the intermediate of plant growth regulator ' Inshuzhi '.
2,4-D is the solid shape.It is the steroids selective herbicide, by deep processing make 2, the serial herbicides such as 4-D butyl ester, isobutyl ester, different monooctyl ester, amine salt, dimethylamine salt, its low concentration play the effect of coordinate plant growth when using.
Polyoxyethylene nonylphenol ether is emulsifier, and dimethyl formamide, cyclohexanone are organic solution.
Plant growth regulator of the present invention, be to get the gibberellic acid of weight 0.001～99.990%, the heteroauxin of weight 0.001～99.990%, the malonic acid of weight 0.001～99.990%, 2 of weight 0.001～99.990%, 4-D, the dimethyl formamide of weight 0.001～99.990%, the polyoxyethylene nonylphenol ether of weight 0.001～99.990%, the cyclohexanone of weight 0.001～99.990%, stir evenly through mixing and to be mixed with mixed solution, formulated mixed solution is mixed with the potassium dihydrogen phosphate buffer solution of weight 30～40% by 60～70% of its weight, be mixed with plant growth regulator of the present invention through stirring evenly.
Get plant growth regulator formulation of the present invention and be 4% aqua, carry out animal experiment through sending Guiyang Medical College toxicity inspection center, it is as follows that its virus reason test detects data extract:
1, rat acute Oral toxicity test:
Female: LD
50Be ﹥ 5000mg/kg, belong to the lower toxicity agricultural chemicals; Male: LD

2, rat acute percutaneous toxicity test:
Female: LD
50Be ﹥ 2000mg/kg, belong to the lower toxicity agricultural chemicals; Male: LD
50Be ﹥ 2000mg/kg, belong to the lower toxicity agricultural chemicals.
3, rat acute toxicity on inhalation test:
Female: LC
50Be ﹥ 2000mg/mg
3, belong to the lower toxicity agricultural chemicals; Male: LC
50Be ﹥ 2000mg/mg
3Belong to the lower toxicity agricultural chemicals.
4, Rabbits with Acute skin irritatin test:
The skin irritatin mean scores is up to 0, and this plant growth regulator is planted white rabbit skin nonirritant to New Zealand.
5, rabbit eyes irritant test:
Eye irritation score index (I.A.0.I) is up to 10.5, and less than 5, this plant growth regulator is planted the white rabbit eyes to New Zealand to be had slightly to the moderate excitant behind average integral index (M.I.0.I) 4d.
6, guinea pig skin allergy (sensitization) test:
The sensitization rate is 0%, and this plant growth regulator belongs to weak sensitization agricultural chemicals.
Plant growth regulator of the present invention is sprayed in upper tobacco leaf, its cigarette strain growing stage shortens, can promote upper tobacco leaf to hack, fall alkali, increase potassium, yield of tobacco increases, and has reduced the generation of the rear dust tobacco leaf of upper tobacco leaf baking, and its tobacco leaf structure is slightly loose, color is slightly dark, gloss is slightly strong, the perfume quantity foot, upper leaf list leaf is slightly heavy, has effectively improved the ratio of medium grade cigarette on the upper tobacco leaf, thereby increases tobacco grower's income.
