Background technology
Nicotine is the important chemical composition in the tobacco, and it is higher commonplace that present China produces tobacco leaf upper leaf nicotine content, has a strong impact on the upper leaf availability, restricted the foundation and the development of national brand.The tobacco planting brainstrust is devoted to carry out the regulation and control of tobacco smoke alkaloid always, and major measure (1) control nitrogenous fertilizer usage amount attempts by reducing tobacco the absorption of nitrogenous fertilizer to be reduced the synthetic of nicotine, is subjected to the influence of soil, DeGrain.With time control nitrogen yield of tobacco is descended, reduced tobacco grower's income, promote very difficult; (2) increase planting density: density increases, and the yield of tobacco quality descends, and the tobacco grower takes in minimizing, promotes difficulty; (3) postponement is pinched, gathered in advance: the tobacco leaf presentation quality descends, and the tobacco grower takes in reduction; Other measure such as drought resisting, balanced nutrients etc. are subjected to the influence of basic condition restriction and the tobacco grower's technical quality difficulty that operates very big.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the deficiencies in the prior art, by inventor's concentrating on studies and repetition test for many years, provide a kind of and can regulate and control tobacco smoke alkaloid content, science practicality, be easy to promote the method with mixture reduction nicotine content of no negative interaction.
To achieve these goals, a kind of method that the present invention relates to mixture reduction nicotine content, its technical method case is such:
The operating procedure of this method is as follows:
The preparation of A, mixture: use 10mg/kg to 50mg/kg heteroauxin+40mg/kg to 80mg/kg malonic acid (promptly 10~50 mg/kg heteroauxins (IAA) add 40~80 mg/kg malonic acid) preparating mixture, with general utility balance difference weighing heteroauxin 7.5 grams and malonic acid 60 grams, by the 1 hectare of amount of spraying preparation; Dissolve aforementioned heteroauxin (heteroauxin is water insoluble) with 375 milliliters of liquor, with little water (to the negligible minor amount of water of 750 kg water described later) dissolving malonic acid, standby;
B, water constant volume: by 750 kilograms of per hectare waters, water is added constant volume in the above-mentioned heteroauxin for preparing+malonic acid mixture, standby;
C, field spray: the above-mentioned mixture soup for preparing is packed in the sprayer, go to the field after 4 of that afternoons, by 0.75 kilogram of every strain spraying liquid at cigarette strain foliage-spray once; If rain in 6 hours, fill spray once again, otherwise soup no longer fill spray.
D, cleaning: clean sprayer, remove residual liquor, for future use.
A kind of method with mixture reduction nicotine content that the present invention is alleged, when using 7.5 gram heteroauxins (IAA) to add 60 gram malonic acid mixtures, its effect that reduces nicotine content is more obvious.
The alleged a kind of mixture of the present invention reduces the method for nicotine content, has easy and simple to handlely, is easy to grasp, cost is lower, the tobacco leaf output value, output are had no adverse effect, environment is not had characteristics such as negative effect, behind use the present invention, it is obvious that nicotine content of tobacco leaves is reduced effect.For example: not using tobacco upper leaf nicotine content of the present invention is 6.87%, use the present invention, after 7.5 gram heteroauxins (IAA) add 60 gram malonic acid mixture process, the upper leaf nicotine content is 3.45%, contrast nicotine content 6.87%, reduce by 3.42 percentage points in nicotine, the range of decrease is 49.78%.Promotion prospect of the present invention is wide, for China's tobacco business provides a kind of new thinking and method to the regulation and control of nicotine; The present invention can be widely used in producing the area and the industry of tobacco leaf.
Embodiment
The present invention is described in detail as follows to its technical scheme in conjunction with specific embodiments: a kind of method with reducing nicotine content from chemical that the present invention is alleged is made of following operating procedure:
The preparation of A, mixture: by the 1 hectare of amount of spraying preparation,, with 375 milliliters of liquor dissolving heteroauxins, dissolve malonic acid again with little water with balance difference weighing indolylbutyric acid 7.5 grams and malonic acid 60 grams, standby;
B, water constant volume: by 750 kilograms of waters of per hectare water, water is added constant volume in the above-mentioned heteroauxin for preparing+malonic acid mixture, standby;
C, field spray: the above-mentioned mixture soup for preparing is packed in the sprayer, go to the field after 4 of that afternoons, by 0.75 kilogram of every strain spraying liquid at cigarette strain foliage-spray once; If rain in 6 hours, fill spray once again, otherwise soup no longer fill spray.
D, cleaning: clean sprayer, remove residual liquor, for future use.
