Problems solved by technology

At present, there are many kinds of plant growth regulators used in the scientific research and production of sorghum in my country. Among them, ethephon, paclobutrazol, chlormequat, and siquat are mainly used to reduce plant height and prevent lodging, but the side effects include: reducing Leaf chlorophyll content and net photosynthetic rate reduce photosynthetic potential and dry matter production, limit ear development and reduce yield; salicylic acid, jasmonic acid, methyl jasmonate, etc. have the effect of improving cold resistance of sorghum, but the application is not enough. It is safe, if the concentration is too low or too high, it will inhibit the germination of seeds, reduce the length and quality of buds and roots, and cause the seedlings to wilt; later spraying will easily lead to late maturity and reduce the yield and quality of sorghum

Embodiment 1

[0054] The present embodiment provides a preparation method of a sorghum resistance and lodging regulator, and the steps are as follows:

[0055] Add 270.0 g of betaine to 300 ml of water, and after complete dissolution, add 9.0 g of sodium naphthalene acetate to form solution I; then, add 189.0 g of sodium benzoate to 200 ml of water, and after complete dissolution, form solution II. After that, solution I and solution II were mixed, 20 ml of alkyl glycoside APG0810 was added, and the volume was made up to 1000 ml with water.

Embodiment 2

[0057] The present embodiment provides a preparation method of a sorghum resistance and lodging regulator, and the steps are as follows:

[0058] Add 270.0 g of betaine to 300 ml of water, and after complete dissolution, add 9.0 g of sodium naphthalene acetate to form solution I; then, add 54.0 g of sodium benzoate to 200 ml of water, and after complete dissolution, form solution II. After that, solution I and solution II were mixed, 20 ml of alkyl glycoside APG0810 was added, and the volume was made up to 1000 ml with water.

Embodiment 3

[0060] The present embodiment provides a preparation method of a sorghum resistance and lodging regulator, and the steps are as follows:

[0061] 270.0 g of betaine was added to 300 ml of water, and after complete dissolution, 4.5 g of sodium naphthalene acetate was added to form solution I; then, 189.0 g of sodium benzoate was added to 200 ml of water, and after complete dissolution, solution II was formed. After that, solution I and solution II were mixed, 20 ml of alkyl glycoside APG0810 was added, and the volume was made up to 1000 ml with water.

Abstract

The invention relates to preparation and application of a stress-resistant lodging-resistant regulator for sorghum. The regulator provided by the invention comprises the following components: 4.5 to 9.0 g/L of sodium naphthalene acetate, 54.0 to 189.0 g/L of sodium benzoate, 90.0 to 270.0 g/L of betaine, 20 ml/L of an active agent and a spreader, and water as a solvent. And the active agent and the spreader are selected from one or more of alkyl glycoside APG0810 and APG0814. The regulator provided by the invention can significantly enhance the adversity stress resistance and lodging resistance of sorghum, increase the grain weight per ear and the grain yield of sorghum, and increase the sorghum yield by 15% or above. Meanwhile, the product has the characteristics of low cost, convenience in use, less field residue and the like, is easy to popularize and apply, and has a positive promotion effect on sorghum production in China.

Description

technical field [0001] The invention relates to the technical field of plant growth regulators, in particular to the preparation and application of a sorghum resistance and lodging regulator. Background technique [0002] Sorghum is an important grain crop in my country and can be used as grain, feed and food processing. The main nutrients of sorghum include: crude protein, crude fat, carbohydrates, crude fiber, and trace elements such as calcium, phosphorus, iron, and B vitamins; sorghum rice can be used as rice, as well as for milling and making various pasta; Sorghum protein is mostly alcohol-soluble protein and has high tannin content. Therefore, sorghum is mainly used in food processing and liquor and vinegar brewing, and is an important raw material for brewing famous liquor. [0003] With the development of my country's food processing industry, the annual output of sorghum cannot meet the needs of the processing industry. Sorghum is a miscellaneous grain crop with s...
