Embodiment 1

[0058] This embodiment provides a preparation method of millet anti-stress and anti-lodging regulator, the specific steps are as follows:

[0059] Add 187.5g of betaine to 400ml of water, after it is completely dissolved, add 225.0g of choline chloride to form solution I; after that, add 18.75g of cyprodinol to 40ml of ethanol, and after the dissolution is complete, form solution II. Afterwards, mix solution I and solution II, add 20ml of alkyl glycoside APG0810, and dilute to 1000ml with water.

Embodiment 2

[0061] This embodiment provides a preparation method of millet anti-stress and anti-lodging regulator, the specific steps are as follows:

[0062] Add 187.5g of betaine to 400ml of water, after it is completely dissolved, add 225.0g of choline chloride to form solution I; then, add cyprodinol 26.25g to 40ml of ethanol, and after it is completely dissolved, form solution II. Afterwards, mix solution I and solution II, add 20ml of alkyl glycoside APG0810, and dilute to 1000ml with water.

Embodiment 3

[0064] This embodiment provides a preparation method of millet anti-stress and anti-lodging regulator, the specific steps are as follows:

[0065] Add 187.5g of betaine to 400ml of water, after completely dissolving, add 337.5g of choline chloride to form solution I; after that, add 18.75g of cyprodinol to 40ml of ethanol, after completely dissolving, form solution II. Afterwards, mix solution I and solution II, add 20ml of alkyl glycoside APG0810, and dilute to 1000ml with water.

Abstract

The invention relates to preparation and application of a stress-resistant lodging-resistant regulator for millet. The conditioning agent is prepared from the following components: 18.75 to 26.25 g / L of cyclopropyl pyrimidinol, 225 to 337.5 g / L of chloro-choline chloride, 187.5 to 262.5 g / L of betaine, 20 ml / L of an active agent and a spreader, 40 ml / L of ethanol and the balance of water. 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 adversity stress resistance and lodging resistance of the millet, increase the grain weight per ear and the grain yield of the millet, and increase the yield of the millet by 16% 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 millet production in China.

Description

technical field [0001] The invention relates to the field of plant growth regulators, in particular to the preparation and application of a millet stress and lodging resistance regulator. Background technique [0002] Millet is mainly distributed in arid, semi-arid, barren saline-alkali and low temperature and cool areas in northern my country. Millet has the characteristics of rich nutrition, drought and barren resistance, and both food and grass. Studies have shown that millet is naturally nutritious, with a protein content of 11.2% to 13.4% and a fat content of 4.5%, both of which are higher than those of rice and wheat flour; , the content of lysine is 0.22%~5.24%, the content of methionine is 0.4%, the content of tryptophan is 0.25%, the content of leucine is 1.87%, the content of threonine, isoleucine and valine are all in 0.42% to 2.88%; the content of vitamins is also rich, and the content of crude fiber is the lowest. It is a good nourishing product for puerpera, ...
