Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to a corn growth regulator and a preparation method thereof. Background Art

[0002] Plant growth regulators, also known as plant regulators, refer to pesticides that regulate the growth and development of plants. They can promote or inhibit the growth and development of plants at relatively low concentrations. At present, the application areas of plant regulators in my country range from food crops such as wheat, corn, rice, and soybeans to vegetables and fruits such as tomatoes, cucumbers, peppers, grapes, and watermelons, to fruit preservation, and to the cultivation of various tea trees and flowers. They have played an important role.

[0003] Corn is an annual herbaceous plant of the Poaceae family, native to Central and South America. It is an important food crop in the world, widely distributed in the United States, China, Brazil and other countries. Compared with traditional food crops such as rice and wheat, corn has strong drought resistance, cold resistance and excellent environmental adaptability. Corn has high nutritional value and is an excellent food crop. As a high-yield food crop in China, corn is an important source of feed for animal husbandry, breeding, aquaculture, etc. It is also one of the indispensable raw materials for food, medical and health, light industry, chemical industry, etc.

[0004] Common growth regulators for corn include high yield hormone, ethephon, corn robust hormone and aminoethyl ester, but these growth regulators are basically single-type products, with large dosage and unstable yield increase. Therefore, how to provide a growth regulator that can stably and efficiently increase corn yield has become an urgent problem to be solved in the field. Summary of the invention

[0005] In view of this, the present invention provides a corn growth regulator and a preparation method thereof, the purpose of which is to solve the technical problems of large dosage of existing growth regulators and unstable yield increase.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] The present invention provides a corn growth regulator, comprising the following components in parts by weight:

[0008] 1-10 parts of methyl disulfone, 1-10 parts of indoleacetic acid, 10-30 parts of environmentally friendly enzymes, 10-20 parts of ethephon, 1-5 parts of stabilizer, 10-30 parts of co-solvent, and 80-120 parts of water.

[0009] Furthermore, the stabilizer includes one or more of citric acid, potassium citrate, ammonium sulfate and white carbon black.

[0010] Furthermore, the co-solvent includes isopropanol and / or ethanol.

[0011] Furthermore, the environmentally friendly enzyme is a liquid produced by fermenting a mixture of fruit peels, vegetable residues, brown sugar and water.

[0012] The present invention provides a method for preparing the above-mentioned corn growth regulator, comprising the following steps:

[0013] S1, mixing mesosulfuron, indoleacetic acid and a co-solvent to obtain a premixed solution A;

[0014] S2, mixing the environmentally friendly enzyme and water to obtain a premixed solution B;

[0015] S3. Mix the premixed liquid A, the premixed liquid B, ethephon and the stabilizer to obtain a corn growth regulator.

[0016] Furthermore, in step S3, the mixing temperature is 20 to 30° C., and the mixing time is 20 to 60 minutes.

[0017] It can be seen from the above technical solution that compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The effective combination of methyl disulfone and indoleacetic acid in the present invention can significantly promote the growth of corn, increase plant height, stem thickness and leaf area, thereby improving the photosynthesis efficiency of corn and further promoting the increase of yield. Environmentally friendly enzymes can effectively regulate the morphology of corn plants, making them stronger, leaves more dense green, root systems more developed, and enhancing the overall stress resistance of plants. The addition of ethephon helps to regulate the growth cycle of corn, promotes corn to mature early, shortens the growth cycle, and provides more flexible planting arrangements for agricultural production. The introduction of stabilizers can effectively improve the disease resistance of corn plants, reduce the occurrence of diseases and insect pests, reduce the amount of pesticides used, and is conducive to the protection of the ecological environment. The use of cosolvents allows the active ingredients in the corn growth regulator to be more evenly distributed in the soil, improves the utilization rate of fertilizers, and reduces the waste of resources.

[0019] In summary, the corn growth regulator provided by the present invention can promote the growth of beneficial microorganisms in the soil on the one hand. The beneficial microorganisms can improve the physical and chemical properties of the soil and increase the content and conversion efficiency of soil organic matter. They have the functions of releasing potassium, releasing phosphorus and fixing nitrogen. After being applied to the soil, the bacteria quickly proliferate to form a group advantage to decompose the nitrogen, phosphorus and potassium fixed in the soil for crops to absorb and utilize, thereby indirectly increasing the corn yield; on the other hand, it can reduce or avoid the side effects of small corn cobs and thin stalks and reduced yield, and effectively transfer nutrients to reproductive growth, thereby increasing the corn yield.
