Embodiment 1

[0042] By weight, take 1 part of 80% naphthaleneacetic acid plus 2.5 parts of 25% solvent ammonia, stir and add 1 part of water, mix to make an aqueous solution, fully stir and fully react, stand still, take out the supernatant about 3.75 Parts, plus 4.5 parts of water, so that 8.25 parts of NAA ammonia solution. Take 3×10 -5 Add a little ethanol solution to 99.9% brassinolide, stir to dissolve, add 3.75 parts of water to obtain ethanol solution of brassinolide. The above-mentioned NAA ammonia solution is fully mixed with the brassinolide ethanol solution to obtain 12 parts of mixed solutions, and finally measure the effective content of naphthaleneacetic acid and brassinolide, so that the contents of naphthaleneacetic acid and brassinolide are respectively 6%. and 0.002% of a wheat plant growth regulator composition.

Embodiment 2

[0044] By weight, take 1 part of 80% naphthaleneacetic acid plus 2.5 parts of 25% solvent ammonia, stir and add 1 part of water, mix to make an aqueous solution, fully stir and fully react, stand still, take out the supernatant about 3.75 Parts, add 1.5 parts of water to get 5.25 parts of NAA ammonia solution. Take 3×10 -5 Add a little ethanol solution to 99.9% brassinolide, stir to dissolve, add 3.75 parts of water to obtain ethanol solution of brassinolide. The above-mentioned NAA ammonia solution is fully mixed with the brassinolide ethanol solution to obtain 9 parts of the mixed solution, and finally measure the effective content of naphthaleneacetic acid and brassinolide, so that the contents of naphthaleneacetic acid and brassinolide are respectively 8%. and 0.0002% of a wheat plant growth regulator composition.

Embodiment 3

[0046] By weight, take 1 part of 80% naphthaleneacetic acid plus 2.5 parts of 25% solvent ammonia, stir and add 1 part of water, mix to make an aqueous solution, fully stir and fully react, stand still, take out the supernatant about 3.75 Parts, namely the ammonia solution of NAA. Take 3×10 -5 Add a little ethanol solution to 99.9% brassinolide, stir to dissolve, add 3.75 parts of water to obtain ethanol solution of brassinolide. The above-mentioned NAA ammonia solution is fully mixed with the brassinolide ethanol solution to obtain 7.5 parts of the mixed solution, and finally measure the effective content of naphthaleneacetic acid and brassinolide, so that the contents of naphthaleneacetic acid and brassinolide are respectively 10%. and 0.0002% of a wheat plant growth regulator composition.

Abstract

A plant growth regulator for wheat is composed of naphthylacetic acid, brassin lactone, solvent and assistant. Its advantages are high effect to increase wheat yield by 10-15% and resist damage of weather, and no environmental pollution.

Description

【Technical field】 [0001] The invention relates to a crop plant growth regulator composition, and also relates to a production method of the composition. More specifically, it relates to a plant growth regulator composition for wheat, and a production method of the composition. 【Background technique】 [0002] In the Huanghuai winter wheat region, uncontrollable disastrous weather often occurs during the stage of wheat heading and flowering to grain filling, such as dry and hot wind, continuous rain, and late green withering, which seriously affect the grain filling and normal maturity of wheat grains. These catastrophic weathers occurred for a short time and caused great harm. Conventional cultivation management has been out of control. The yield reduction is mostly 10%-20%, and the thousand-grain weight is reduced by 1-3 grams. In severe years, the yield can be reduced by more than 30%, and the thousand-grain weight can be reduced by 5-10 grams, which has become a restricti...
