Naphthylacetic acid-sodium nitrophenolate compounded water aqua, preparation method and application of water aqua as yield-increasing drought-resisting plant growth regulator

Abstract

The invention discloses naphthylacetic acid-sodium nitrophenolate compounded water aqua which is mainly prepared from the following raw materials by weight percentage: 2.0-2.2 percent of 1-naphthylacetic acid, 0.58-0.78 percent of compound sodium nitrophenolate, 0.01 percent of natural brassinolide, 0.05 percent of uniconazole and the balance being water. An environment-friendly yield-increasing drought-resisting plant growth regulator can be developed by taking high efficiency, broad spectrum, no pollution and environmental friendliness as rules, combining 1-naphthylacetic acid with the compound sodium nitrophenolate in different proportions, then adding a proper amount of natural brassinolide and uniconazole and utilizing the synergistic effect of natural brassinolide and uniconazole. The water aqua is used in a key stage of growth and development of wheat, can be used for increasing the quantity of secondary roots and the activity of a root system, promoting deep extension and growth of the root system and enhancing the capability of absorbing various nutrients and water so as to improve the drought resistance of the wheat and realize safety and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of crop growth regulators, and in particular relates to a naphthalene ethyl-sodium nitrate compound water agent, a preparation method and its application as a yield-increasing and drought-resistant plant growth regulator. Background technique [0002] The 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 f...

Problems solved by technology

Therefore, the use of NAA in agricultural production must pay special attention to the concentration, dosage, application time and physiological state of the plant, otherwise it will not only fail to achieve the purpose of increasing production, but will cause irreparable losses

However, the commercial NAA used in production is mostly powdery solid with a content of more than 99%. It is difficult to dissolve in water. It needs to be dissolved in hot water or alcohol when used. The preparation process is cumbersome and the concentration is difficult to control, resulting in unstable or insignificant use effects. , and even produce phytotoxicity, which greatly limits the scope of its application
