Embodiment 1

[0021] The 0.12kg mass fraction is that the sodium hydroxide solution of 0.8% is sprayed in 0.8kg starch by means of spraying, and then the starch is dried to a moisture content of 1% at 60 ° C; then the dried starch is added to kneading. In the reactor, add 0.01kg of maleic anhydride modified polyethylene wax and control the temperature to 40°C. After kneading and stirring for 30 minutes, the temperature is raised to 110°C. 0.22kg of activated clay nano powder and 2kg of ethanol were added to the reaction kettle, 0.02kg of amino silicone oil was added to the reaction kettle after stirring and mixed uniformly, the temperature was raised to 40 ° C after uniformly mixed, and the reaction was stirred for 30min, and then 0.01kg of polymethyl methacrylate was added. The triethoxysilane was stirred and reacted for 1 hour, and after completion, the temperature was lowered to room temperature, filtered, and the obtained inorganic nanopowder was vacuum-dried at 80° C. for 1 hour to obta...

Embodiment 2

[0023] The 0.18kg mass fraction is that the sodium hydroxide solution of 1.6% is sprayed in 1.2kg starch by means of spraying, and then the starch is dried to a moisture content of 2.5% at 70 ° C; then the dried starch is added to the kneading process. In the reactor, 0.06kg of maleic anhydride modified polyethylene wax was added and the temperature was controlled to 50°C. After kneading and stirring for 40min, the temperature was raised to 115°C, and the reaction was performed for 2.5h. After crushing, hydrophobic starch with an average particle size of 100 μm was obtained. . 0.35kg of silicon dioxide nano powder and 3.5kg of ethanol were added to the reaction kettle, 0.03kg of amino silicone oil was added to the reaction kettle after stirring and mixing, and the temperature was raised to 50 ° C after mixing, and the reaction was stirred for 45min, and then 0.02kg of polymer was added. Methyltriethoxysilane, continue to stir and react for 3h, after completion, cool down to ro...

Embodiment 3

[0025] The 0.24kg mass fraction is that the sodium hydroxide solution of 2.4% is sprayed in the 1.5kg starch by spraying, and then the starch is dried to a moisture content of 5% at 80 ° C; then the dried starch is added to the kneading. In the reactor, 0.15kg of maleic anhydride modified polyethylene wax was added and the temperature was controlled to 60°C, kneaded and stirred for 60 minutes, then heated to 120°C, reacted for 5 hours, and crushed to obtain hydrophobic starch with an average particle size of 200 μm. Add 0.4kg kaolin nano-powder and 5kg ethanol into the reactor, stir and mix homogeneously, add 0.05kg amino silicone oil into the reactor, mix homogeneously and heat up to 60°C, stir for 60min, then add 0.03kg polymethyl triacetate Ethoxysilane, continue to stir and react for 5h, after completion, the temperature is lowered to room temperature, filtered, and the obtained inorganic nanopowder is vacuum-dried at 100° C. for 5h to obtain the hydrophobic inorganic nanop...

Abstract

The invention relates to the field of agricultural product medicament preparation, in particular to a preparation method of a pollution-free potato suckercide based on a novel hydrophobic material. The pollution-free potato suckercide comprises hydrophobic starch, hydrophobic inorganic nano powder and an ethanol solution, the two environment-friendly hydrophobic powder new materials are prepared from cheap materials, and the preparation method is very simple, so that the bud inhibition treatment cost of the suckercide for potatoes is not greatly different from that of the conventional common method, but the materials adopted by the suckercide prepared by the method are non-toxic environment-friendly materials, food safety risks do not exist, pesticide residues do not need to be detected, and the suckercide has wide application prospects.

Description

technical field [0001] The invention relates to the field of agricultural product pharmaceutical preparation, in particular to a preparation method of a pollution-free potato sprout inhibitor based on new hydrophobic materials. Background technique [0002] Potato is still a living plant during storage and maintains normal life activities. When the dormancy is released, it begins to sprout and grow under suitable conditions, resulting in a large consumption of water and nutrients, and a large amount of "nightshade" is produced around the bud eye. "Vegetarian", which seriously affects the edible value and processing value of potatoes. [0003] CN107197938A discloses a method for inhibiting germination of potatoes, including: drying, inhibiting germination, preserving freshness, and storing; the method is simple, can be processed in batches, and has low cost, which is only 20-22% of the cost of low-temperature storage method, and when stored for 8 months The germination rate ...
