Embodiment Construction

[0023] Below in conjunction with the embodiment that mixes 1kg flue-cured tobacco drought-resistant agent, the present invention will be further described:

[0024] ① Preparation of IAA and ABA mother liquor: weigh IAA100mg and ABA30mg on an analytical balance, put it into a 100ml volumetric flask, add ethyl acetate to dissolve IAA and ABA, then constant volume, keep the mass fraction of IAA and ABA mother liquor as 4%, the The operation is carried out at a temperature of 20°C and a relative humidity of 70%; the prepared IAA and ABA mother liquors are stored in a refrigerator at 4°C for later use;

[0025] ②Mix the mother liquor of IAA and ABA with Tween: weigh 50g of Tween, measure 1.0g of the mother liquor of IAA and ABA with a straw or measuring cylinder, pour it into a container filled with Tween, and keep it at a temperature of 20°C and a relative humidity of 70%. Stir evenly to obtain a mixed mother liquor;

[0026] ③The melting of lanolin: take lanolin 0.95kg, heat and...

Abstract

The invention discloses a drought-resistant agent for flue-cured tobacco. The drought-resistant agent for the flue-cured tobacco is a product prepared by the following steps of: preparing mother liquor from auxin and abscisic acid serving as basic raw materials, mixing the mother liquor with Tween to obtain mixed liquor, and mixing the mixed liquor with molten wool grease uniformly, wherein the content of the auxin is 98 to 99 percent, and the content of the abscisic acid is 10 percent; the mass fraction of the mother liquor prepared from the auxin and the abscisic acid is 1 to 5 percent; the quality index of the Tween is that the water content is less than or equal to 3 percent; the mass ratio of the mother liquor to the Tween is (1-2 percent):(98-99 percent); the molten wool grease is prepared by heating and melting at the temperature of between 60 and 80 DEG C and the relative humidity of more than or equal to 80 percent; and the mass ratio of the mixed liquor to the molten wool grease is (0.5-2 percent):(98-99.5 percent). After the drought-resistant agent is coated on the cross section of the top of a stem after the topping of a tobacco strain, the drought resistance of tobacco at the late growth stage can be improved, the content of tobacco potassium can be improved, and the content of tobacco nicotine can be reduced; and the drought-resistant agent has the advantages that: the consumption and cost are low, the operation is simple and convenient, key technical points are easy to grasp, and the drought-resistant agent has high applicability and multiple functions.

Description

technical field [0001] The invention relates to the technical field of growth regulators, in particular to a drought-resistant agent. Background technique [0002] There are two ways to use traditional crop drought-resistance agents, one is foliar spraying, and the other is applying it to the soil. [0003] The anti-drought agent sprayed on the foliage reduces the opening of the stomata of the crop leaves, thereby reducing the stomatal conductance of the leaves, reducing part of the ineffective transpiration of the crops, thereby reducing the water consumption of the crops and improving the drought resistance of the crops. But flue-cured tobacco has strict restrictions on all foliar sprays, because improper operation will seriously affect the appearance quality of tobacco leaves. [0004] The anti-drought agent applied to the soil is to increase the activity of various enzymes in the root system of the crop and promote the development of the root system of the crop. The dev...
