Abstract

A biological bud depressant for tobacco is a mixture of coconut oil, C12-C28 fatty acid (lauric acid, myristic acid, palmic acid, oleic acid, etc), agricultural emulsifier and water. Its advantages are high effect on suppressing bud, high yield of tobacco, no chemical residue, and low cost.

Description

Tobacco germination inhibitor
Technical field: the present invention relates to a kind ofly be used to suppress that the long biotype of cigarette strain power blastogenesis is agricultural presses down the bud agent.
Background technology: suppressing the growth of tobacco leaf lateral bud is to improve one of important measures of yield of tobacco and quality.Traditional is artificial time-consuming except that bud, and the labour has high input.The tobacco germination inhibitor that uses mainly is chemosynthesis at present, as removing bud logical (Pendimethalin) and maleic Min (Flumetralin) etc., uses this class to press down the bud agent, partly in the residual tobacco leaf of chemical substance, harmful to the smoker, in the residual soil, be unfavorable for back stubble crop growth, the pressing down the bud agent and also can influence the tobacco leaf metabolism of chemosynthesis, cause part tobacco leaf teratogenesis, blade is little, causes yield of tobacco to descend, when using the people there is excitant, can causes the human allergy to react.
Chinese patent CN-1029656C announced a kind of be used for the blastogenesis of cigarette strain power long press down the bud agent, be rape oil 24-55%, kerosene 40-70%, potassium sulphate 1-3% forms.
Summary of the invention: the purpose of this invention is to provide a kind of efficient bud, no chemosynthesis residue, non-stimulated to the people of pressing down, the biotype cigarette strain wooden fork bud with low cost that can promote tobacco leaf to grow again presses down the bud agent.
According to the present invention, use cocoa butter, the C of effective dose 8-C 24The mixture of fatty acid, agricultural emulsifier and water can reach goal of the invention substantially.
Following tobacco germination inhibitor, better effects if, the volume or weight ratio of each composition consumption is: cocoa butter 30-65 milliliter C 8-C 24Fatty acid 5-15 gram agricultural emulsifier 5-15 ml water 5-60 milliliter is preferably: cocoa butter 40-60 milliliter C 8-C 24Fatty acid 8-12 gram agricultural emulsifier 8-15 ml water 25-50 milliliter, the best is: cocoa butter 45-55 milliliter C 8-C 243045 milliliters of fatty acid 9-11 gram agricultural emulsifier 10-13 ml waters.
C 8-C 24Fatty acid comprises saturated fatty acid and unsaturated fatty acid, and they can be one or more any amount combinations in lauric acid, myristic acid, palmitic acid, oleic acid, palmitic acid or the stearic acid.Agricultural emulsifier can be agricultural unemul, is good with the TX-10 emulsifier.
Press down the sylvite and the zinc salt that can also contain trace in the bud agent, with potassium dihydrogen phosphate and zinc sulphate for well.
Cocoa butter is the commercially available prod, and it is the oil content of squeezing out in the cocoanut tree fruit, uses the technical grade higher level for well.
Tobacco germination inhibitor of the present invention, can produce in order to the below method: at first quantitatively adding an amount of water in the cocoa butter, add fatty acid in proportion, can suitably heat when temperature is low, warm-up time and temperature can be dissolved in wherein with fatty acid exceeds.After cooling, add emulsifier, stir, packing after emulsification is finished is tobacco germination inhibitor of the present invention.This is a stoste, during use, needs dilute with water for using liquid.
Tobacco germination inhibitor stoste is when temperature is low solidifies attitude, water-solubleization of should heating before the dilution.Dilution factor to be to contain 0.3-1.0 gram for well in the application liquid of content of fatty acid after per 100 milliliters of dilutions, with the 0.5-0.8 gram for better.
Using method is a conventional method, promptly binds at cigarette strain initial bloom stage, promptly uses the same day and presses down the bud agent, adopts special-purpose applicator or writing brush to smear the lateral bud position, once can reach bud inhibition effect.
Of the present inventionly press down the bud agent, its superiority shows as:
(1) test of pesticide effectiveness shows, cigarette strain power bud is had the bud effect that significantly presses down.Using 1 mu of cigarette strain experimental field, after effect shows as and uses a week, press down the bud rate and reach 100%, is to be 95% after 99%, six week after all around.Bud inhibition effect is obvious.
(2) raw material sources are in biology, and medicament can not cause the chemistry injury to plant, and noresidue and toxicity do not influence tobacco leaf metabolism and quality of tobacco, and the effect that promotes the tobacco leaf growth is arranged.To human body nonirritant, not contaminated soil.Above-mentioned 1 mu of experiment Tanaka, half uses for experimental group and presses down the bud agent, and second half implements the artificial bud that removes for control group.The result shows: 25.3 centimetres of the long average out to of experimental group plant six weeks back top, and control group is 25.1 centimetres, experimental group is not found abnormal leaf, the lateral bud growth is suppressed, but upper tobacco leaf is normal growth still, shows two groups of qualities of tobacco and output no significant difference, and pressing down bud agent and performance has the growth promotion effect.Through to tobacco leaf and soil analysis check, find no harmful residue, touch experiment through animal skin, nontoxic pair acts on and spread effect.
(3) raw material is easy to get, and is inexpensive.Every mu of plantation field use cost is about 8 yuan, presses down the bud agent well below other.
