Description
Technical Field
The invention relates to the technical field of preparation of tobacco bud inhibitors, in particular to a tobacco bud inhibitor suspending agent, a preparation method and application thereof.
Background
China is the biggest tobacco producing and consuming country all over the world, cigarettes around the world are produced and consumed, tobacco is one of important economic crops in China, and in planting production, in order to improve the yield and quality of tobacco leaves, top-off right is an indispensable link; because each leaf axillary of the tobacco plant has one or more axillary buds, the tobacco plant is usually in a latent state before topping due to the advantage of the top end of the tobacco plant; after the tobacco plant is topped, because the inhibiting effect of the auxin on the axillary buds is artificially removed, the latent axillary buds can rapidly germinate from top to bottom and grow into branched tobacco, which inevitably consumes a large amount of nutrient substances and finally reduces the yield and the quality of the tobacco leaves; in the past, after topping, the tobacco production areas in China often carry out traditional manual branch removing and bud removing, which is not only labor-consuming and time-consuming, but also easy to transmit tobacco mosaic virus. In order to save labor, reduce cost, improve the yield and the internal quality of tobacco leaves and avoid cross infection of viruses, a medicament which can effectively inhibit the growth of tobacco axillary buds, namely a chemical bud inhibitor, is ideally selected, and the method also becomes one of the comprehensive technical measures of high-quality cigarettes.
At present, most tobacco companies in China recommend that a chemical bud inhibitor used on tobacco is mainly emulsifiable concentrate, but the traditional emulsifiable concentrate formulation is relatively backward, so that the environment is polluted, and certain potential safety hazards exist in storage and transportation; nowadays, people have increasingly improved living standard and increasingly strengthened environmental awareness, the call for environmental protection is higher and higher, and governments have also continuously come out of more strict industrial environmental protection policies; the new concept of green development is practiced, a green, low-carbon, circulating and sustainable production life style is advocated, ecological environment-friendly cooperation is enhanced, and ecological civilization is built; with the introduction of the method into the ecological era, in combination with the current situation, a chemical preparation which can better control the growth of tobacco axillary buds and is environment-friendly is urgently needed, so that the yield and the quality of tobacco leaves can be improved.
Fluorometylamine, the chemical name of which is N-ethyl-N (2-chloro-6-fluorobenzyl) -2', 6' -dinitro-4-trifluoromethylaniline, is a plant growth regulator, has the functions of contacting and locally absorbing a special tobacco bud inhibitor, has quick tobacco lateral bud inhibition effect and quick absorption, and can be effective only within two hours after application; however, the current market current situation does not meet the use requirement of the toxic bud inhibitors such as flumetralin, and a plant source leading bud inhibitor is actively searched for use; after field application exploration tests, the abscisic acid extracted from alfalfa is prepared into an oil suspension preparation, so that the synergistic effect is good, the use cost is reduced, and the effect of bud inhibition is better.

step five: pumping the mixed solution obtained in the fourth step into a sand mill through a pneumatic diaphragm pump, and serially connecting two sand mills for sanding for 3 hours to obtain suspension;
step six: pumping the ground suspension into a shearing homogenizing kettle through a pneumatic diaphragm pump for homogenizing for 1h to obtain the tobacco bud inhibitor suspending agent.
Further, the stirring time from the first step to the third step is 10-15min, and the stirring speed is 80-120 r/min.
Further, in the fourth step, the shearing time of the materials in the high-speed shearing machine is 1 h.
Furthermore, in the fifth step, the particle size of the suspension particles obtained after sand mills are connected in series and sand milling is below 5 μm.
The application of the tobacco bud inhibitor suspending agent is to dilute the tobacco bud inhibitor suspending agent and apply the diluted tobacco bud inhibitor suspending agent to tobacco plants within 24 hours of topping for chemical bud inhibition.
Compared with the prior art, the invention provides a tobacco bud inhibitor suspending agent, a preparation method and application thereof, and the suspending agent has the following beneficial effects:
1. the abscisic acid extracted from alfalfa serves as a main effective component of the sprout inhibitor, and the abscisic acid tobacco sprout inhibitor suspending agent has an obvious synergistic effect, can be used for inhibiting axillary buds of various tobaccos, is quick in action after application, saves labor, is long in pesticide effect duration and is low in cost.
2.
