Background technology

Tobacco is one of Important Economic crop of China, taking blade as results object. When tobacco enters reproductive stage, must remove top (being commonly called as " pinching "), do not allow it yield positive results. After tobacco is pinched, axil place can constantly grow lateral bud, consumes a large amount of nutrients, affects output and the quality of tobacco. Therefore, tobacco must be removed axillalry bud (being commonly called as " bud picking ") after pinching in time.

The current tobacco bud picking mode of China has chemistry to press down bud and artificial bud picking. Chemistry presses down bud agent saving of work and time, but easily in tobacco leaf, produces residues of pesticides, affects tobacco leaf security, on organic tobacco cultivation, is prohibited from using. Adopt artificial bud picking, every strain tobacco needs bud picking 4～6 times, and the amount of labour used is large, production cost is high, becomes a bottleneck problem of restriction organic farming tobacco development.

After tested, four methods all can reach the effect that suppresses axillalry bud, but also have following shortcoming: the natural preparation method of bud agent and application (patent No. ZL98122743.0) complex process on flue-cured tobacco axillalry bud suppresses thereof of pressing down, is unfavorable for that tobacco grower independently uses; A kind of method (patent No. ZL201010579980.7) amount of labour used of inhibiting bud through bud in organic flue-cured tobacco production is still more; Application (application for a patent for invention CN201210441204.X) use cost that a kind of tobacco germination inhibitor presses down the bud stage tobacco is higher; And a kind of tobacco leaf presses down the tobacco leaf chloride ion content raising of method (application for a patent for invention CN201210352335.0) cultivation of bud, affect quality of tobacco.

Summary of the invention

The invention provides a kind of composition as tobacco germination inhibitor, it contains wood tar and white wine.

The object of this invention is to provide a kind of can be used for organic tobacco cultivation press down bud agent, its production cost is low, can reduce the bud picking amount of labour used, to overcome deficiency of the prior art.

Another object of the present invention is that said composition is applied to tobacco planting district.

Another object of the present invention is for suppressing tobacco axillary bud growth by said composition.

Technical scheme of the present invention: said composition contains wood tar and white wine, the volume ratio of wood tar and white wine is 1:10～25. Wood tar is to utilize the vega discarded objects such as tobacco rod, cigarette root, inapplicable tobacco leaf to fire in charcoal process through 500～700 DEG C, and kiln gas is carried out to a kind of black viscous liquid that cooling recovery obtains, and belongs to the adjunct in charcoal sintering procedure. White wine is to obtain through distillation after utilizing the fermentation of the grain such as corn or Chinese sorghum, and alcohol content is 40～60%.

Preferred version: the volume ratio of wood tar and white wine is 1:15～20.

Compared with " a kind of method (patent No. ZL201010579980.7) of inhibiting bud through bud in organic flue-cured tobacco production ", bud picking saving of labor 3-4 of the present invention/mu, the bud picking amount of labour used reduces more than 50%; Compared with " a kind of tobacco germination inhibitor presses down the application (application for a patent for invention CN201210441204.X) in bud stage tobacco ", the present invention's formula is more cheap, because raw material white wine price is lower than rapeseed oil.
