Problems solved by technology

[0008] Publication number is CN 103931622 A in the invention patent application document, announced the compound water of naphthalene ethyl-sodium nitrate, its main component is by naphthalene acetic acid and complex sodium nitrophenolate However, this patented technology is only used at the jointing stage of wheat. The compound water agent has certain functions of drought resistance and growth promotion, but the components and functions are relatively simple, and the growth promotion effect is still not good, and it does not have disease resistance.
As the saying goes, "three-point planting, seven-point management", winter wheat has a long growth cycle, and it needs to be managed differently to promote growth according to different growth stages. It is difficult to have a uniform standard of growth regulators that can be used throughout the growth cycle.

Embodiment 1

[0020] A winter wheat growth regulator, according to the various stages of wheat growth, the following three regulators are used sequentially, the A-type regulator is used before or after the seedling stage, the B-type regulator is used from the tillering to the jointing stage, and the C-type regulator is used after the jointing stage , the above three regulators are used simultaneously with each stage of winter wheat growth.

[0021] From emergence to overwintering, winter wheat growth is characterized by long roots, long leaves, long tillers, and completion of vernalization stages. Type A regulators are used at the seedling stage, and type B regulators are used at the tillering stage.

[0022] The type A regulator is mainly composed of the following raw materials in weight percentage: 0.65% sodium nitrophenolate, 0.01% natural brassinolide, 1.9% ammonium dihydrogen phosphate, 1% tebuconazole, 2-3% dispersant, and the rest The amount is water. On the basis of protecting seed...

Embodiment 2

[0030] The type A regulator is mainly composed of the following raw materials in weight percentage: sodium nitrophenolate 0.6%, natural brassinolide 0.01%, ammonium dihydrogen phosphate 1.8%, tebuconazole 0.5%, dispersant 1%, and the balance is water.

[0031] The B-type regulator: naphthaleneacetic acid 2.0%, sodium nitrophenolate 0.6%, natural brassinolide 0.05%, uniconazole 0.05%, Zhuangfengan emulsifiable oil 4%, choline chloride 0.05%, the balance for water.

[0032] Described type C regulator: naphthalene acetic acid 2.2%, sodium nitrophenolate 1%, natural brassinolide 0.08%, sodium benzoate 4%, abscisic acid 0.06%, gibberellin 0.003%, triadimefon 5%, Zhuang Feng An emulsifiable oil 4%, trace elements 1%, the balance is water.

Embodiment 3

[0034] The type A regulator is mainly composed of the following raw materials in weight percentage: sodium nitrophenolate 0.65%, natural brassinolide 0.03%, ammonium dihydrogen phosphate 1.8%, tebuconazole 0.6%, dispersant 2%, and the balance is water.

[0035] The B-type regulator: naphthaleneacetic acid 2.0%, sodium nitrophenolate 0.7%, natural brassinolide 0.04%, uniconazole 0.06%, Zhuangfengan emulsifiable oil 4%, choline chloride 0.05%, the balance for water.

[0036] The C-type regulator: naphthaleneacetic acid 2.1%, sodium nitrophenolate 0.9-1.5%, natural brassinolide 0.01-0.15%, sodium benzoate 3%, abscisic acid 0.05%, gibberellin 0.003%, triazole Ketone 5%, Zhuang Feng An emulsifiable oil 5%, trace elements 2%, and the balance is water.

Abstract

The invention discloses a winter wheat growth regulator. The winter wheat growth regulator is divided into a first regulator used before seeding or in the later-seedling stage, a second regulator used from the tillering stage to the elongation stage, and a third regulator used after elongation, and the three regulators are sequentially used according to the growth stage of wheat. The second regulator is mainly composed of, by weight, 2.0-2.2% of naphthalene acetic acid, 0.58-0.78% of compound sodium nitrophenolate, 0.01-0.15% of natural brassinolide, 0.03-0.1% of uniconazole, 0.035-0.06% of choline chloride and the balance of water. The growth regulator is efficient, wide in spectrum, free of public nuisance and environmentally friendly, the naphthalene acetic acid and the compound sodium nitrophenolate with different concentrations are combined and used in the whole growth stage of the wheat, and then, a proper amount of natural brassinolide and uniconazole are added. The winter wheat growth regulator is used in the key growth stage of the wheat, the number of secondary roots can be increased, the activity of the roots can be enhanced, dipping penetration and growth of the roots are promoted, the capacity of absorbing various nutrients and water of the roots is enhanced, and therefore the drought resistance of the wheat is improved, and the winter wheat growth regulator is safe and efficient.

Description

technical field [0001] The invention belongs to the technical field of crop growth regulators, and in particular relates to a drought-resistant plant growth regulator capable of promoting winter wheat yield increase. Background technique [0002] The winter wheat growing season in the Huanghuaihai region, the main wheat producing area in my country, is often threatened by drought. At the same time, due to insufficient irrigation water supply, the wheat yield is greatly affected; however, there is still great potential in the rational use of water resources, and the technical level of drought resistance and water saving It needs to be further improved. In addition, with the continuous change of climate and production conditions, problems such as freezing injury, lodging, green withering, dry and hot wind in production have become increasingly prominent. To sum up, the study of high-yield drought-resistant and frost-resistant plant growth regulators is also an important way to...
