Description

Technical Field

[0001] The invention relates to the technical field of cereal crop dehydration, in particular to a cereal crop dehydrating agent and a preparation method thereof. Background Art

[0002] With the transfer of land, large-scale production has gradually increased. Full mechanization is not only an urgent requirement for agricultural transformation and upgrading, but also the only way to improve the competitiveness of my country's grain prices. The machine harvesting of corn grains has become the "last mile" of the full mechanization of corn production. However, direct harvesting of grains can only be achieved when the moisture content of corn grains reaches less than 25%, otherwise the grain machine cannot be harvested. Manual harvesting and drying are time-consuming and labor-intensive, and it is difficult to control the moisture content of the grains. In the later stage, drying equipment is required for drying. For example, each 200-ton drying tower needs to use 1.5 tons of fuel per day and consume 2,400 degrees of electricity per day, which consumes a lot of fuel and increases carbon emissions.

[0003] The key to solving the problem of mechanical harvesting of grains is to promote early maturity and reduce the moisture content of grains. However, early-maturing varieties often have a large reduction in yield, and farmers and large-scale growers are reluctant to plant them. Therefore, chemical control technology measures, such as chemical ripening and dehydrating agents, provide broad prospects for reducing the moisture content of grains. Summary of the invention

[0004] The object of the present invention is to provide a cereal crop dehydrating agent and a preparation method thereof to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A cereal crop dehydrating agent, comprising the following raw material components by weight: Ferulic acid 125-145 grams; glutamic acid 172-182 grams; potassium humate 255-260 grams; glycine 280-295 grams; citric acid 30-50 grams; sodium chloride 90-110 grams.

[0006] As a further preferred embodiment of the present invention, the raw material components include, by weight: 135 grams of ferulic acid; 175 grams of glutamic acid; 258 grams of potassium humate; 292 grams of glycine; 40 grams of citric acid; and 100 grams of sodium chloride.

[0007] A method for preparing a cereal crop dehydrating agent comprises the following steps: Step 1, physically mixing natural ferulic acid, glutamic acid, potassium humate, glycine, citric acid and sodium chloride, and dissolving them in an ethanol solution to obtain a mixed solution; Step 2: After heating the mixed solution to 130° C., filtering and purifying to obtain dry powder, and packaging to obtain the finished dehydrating agent.

[0008] Mechanism of action: Ferulic acid is used to accelerate the transport of dry matter in plants; Glutamic acid is used to increase the formation of dry matter in plants and has a yield-increasing effect; Potassium humate is used to improve the quality of plant fruits, increase the bulk density of grains, increase the wax layer of fruits, and make grains mature earlier. It is an element that starts dehydration. Glycine is used to speed up the drying precipitation after the transportation of dry matter, so that the maturity of cereal crops is advanced, achieving the effect of early maturity; Citric acid can speed up the absorption of organic acids in plants, improve the utilization of photosynthesis, promote the formation of dry matter in grains, and prevent the decline in nutrient utilization caused by bad weather such as rain. Potassium chloride salt supplements nutrition and keeps the stomata of leaves and bracts open, thus increasing transpiration. Therefore, in the later growth stage of crops (i.e. waxy stage), the dehydrating agent can increase the circulation speed of nutrients (dry matter) in the plant body by 3-4 times, allowing the nutrients in the plant body to quickly complete the aggregation and formation, enrich the internal space in the fruit, and complete the ripening process of reducing water and increasing dry matter. The main dry matter is formed rapidly in the first ten days, and after ten days, the stomata of the plant leaves and peels are opened and no longer closed, and transpiration is used to quickly reduce moisture; thereby achieving the effect of reducing the moisture content by 30% and harvesting 7-10 days earlier.

[0009] Compared with the prior art, the present invention has the following beneficial effects: The organic acid in the cereal crop dehydrating agent is easily decomposed by light and has strong antioxidant properties. It can accelerate the circulation of nutrients in plants. By spraying it in the late growth stage of cereal crops, it can promote the variety to mature 5-10 days earlier and reduce the moisture content of the grain by 30%. The yield is not significantly reduced, and it is ecologically safe and has no residue, meeting the requirements of mechanized harvesting of grains. Compared with machine harvesting of fruit ears, it can save 80-120 yuan / mu, effectively reducing production costs. Implementation
