Description
Technical Field
The invention relates to the field of a bud inhibitor, in particular to an environment-friendly special bud inhibitor for flue-cured tobacco and a preparation method thereof.
Background
Tobacco is one of the important economic crops in China, and leaves are taken as harvest objects. When the tobacco enters the reproductive growth period, the top end of the tobacco must be removed (commonly called as topping), and the tobacco is prevented from flowering and bearing fruits. After the tobacco is topped, lateral buds can continuously grow at the axillary parts of the tobacco leaves, a large amount of nutrients are consumed, the growth and the filling of main stem leaves are influenced, and the yield and the quality of the tobacco are influenced. Therefore, axillary buds (commonly called as 'picking buds') must be removed in time after topping of tobacco, otherwise, as the topping is not carried out, the tobacco plant leaves are not full, the identity is light, the oil content is low, the elasticity is poor, and the taste and the aroma are reduced.
The existing bud picking modes of tobacco comprise chemical bud inhibition and artificial bud picking. The chemical bud inhibition saves labor and time, is generally the main bud inhibition mode adopted at present, but because the bud inhibition agent is used in successive years, the components of the bud inhibition agent are detected to remain in the tobacco sample detection every year. With the improvement of living standard and the enhancement of health consciousness of people, the safety problem of tobacco is getting more and more attention.
Journal of modern pesticides in 2017 for 12 months; "tobacco pesticide residue analysis and detection technology research progress" of vol.16, 6 discloses that, for example, li yi qiang and the like are sampled from main producing areas of tobacco leaves such as fujian, guangdong, hunan, Guizhou, Chongqing, Shanxi, Hubei, Henan, Shandong, Heilongjiang and the like, and pesticide residues of pesticide varieties such as hexachloro-cyclohexane and DDT and the like which are forbidden to be used on tobacco, and pesticide varieties such as aldicarb, imidacloprid and the like which are registered or recommended to be used on tobacco but have easily exceeded the standard in residue, flumetralin (bud sensitivity suppression), desmetron (pendimethalin), maleic hydrazide and the like are subjected to pesticide residue analysis. The applicant finds that the detection result is 0.5mg/kg defined by the national tobacco summary maximum residue limit standard and the CORESTA guidance residue limit standard, 18 samples exceed the standard, and the residues of 9 pesticides such as flumetralin (bud sensitivity inhibitor), diclofop-butyl (pendimethalin), maleic hydrazide and the like are relatively common.
Therefore, the problem of overproof pesticide residues in the tobacco leaves can become an unsafe factor for limiting the development of the tobacco leaves in China in the future, and the control of the pesticide residues in the tobacco leaves in production must be emphasized. How to reduce the harm and influence of pesticide residue on tobacco leaves becomes a problem which needs to be solved urgently by tobacco practitioners at present.
In addition, the components remained in the tobacco leaves of the tobacco processed by the traditional tobacco bud inhibitor not only have no promotion effect on the processing and alcoholization of the tobacco leaves, but also influence the effects after the processing and alcoholization. Furthermore, the traditional sprout inhibitor cannot improve the oil content in tobacco leaves and cannot improve the fragrance of the tobacco leaves.
Chinese patent CN106070207A discloses a bud inhibitor composition capable of reducing the pesticide residue of a bud inhibitor in tobacco leaves, which enhances the bud inhibition effect and reduces the residue of the bud inhibitor by combining flumetralin, butralin and a synergist. The patent has the following defects: the technical scheme does not fundamentally solve the problems that the chemical tobacco bud inhibitor pollutes the environment and is easy to remain, and the bud inhibitor cannot promote the processing and alcoholization of the tobacco leaves.
Chinese patent CN104304322A discloses a tobacco bud inhibitor without public nuisance, pollution and residue, which is prepared by mixing kerosene and absolute ethyl alcohol according to a certain proportion. The patent has the following defects: although the tobacco bud inhibitor overcomes the problems of large pollution and easy residue of the traditional tobacco bud inhibitor, the tobacco bud inhibitor cannot improve the oil content of tobacco leaves and cannot improve the fragrance of the tobacco leaves; the processing and alcoholization of the tobacco leaves cannot be promoted; and the kerosene is flammable and explosive, belongs to a class A fire hazard chemical, has extremely high fire hazard coefficient, is also controlled in transportation and storage, has low use safety, and has great fire hazard to safe production.
Chinese patent CN105594746A discloses a composition containing wood tar and liquor as a tobacco bud inhibitor, which is prepared by mixing wood tar and liquor according to a certain proportion. The patent has the following defects: although the tobacco bud inhibitor overcomes the problems of large pollution and easy residue of the traditional tobacco bud inhibitor, the tobacco bud inhibitor cannot improve the oil content of tobacco leaves and cannot improve the fragrance of the tobacco leaves; the processing and alcoholization of the tobacco leaves cannot be promoted; the preparation process of the wood tar is complex, tobacco stems, tobacco roots and inapplicable tobacco leaves need to be fired at high temperature, the smoke is collected, condensed and recovered, and the wood tar is corrosive and harms the health of workers.
