Problems solved by technology

[0006] However, after the growth and development of cotton enters the initial flowering stage, the growth of the root system slows down and begins to age, and the regeneration of the root system is poor. There is an urgent need for a growth regulator that can prevent premature aging of cotton and promote root regrowth

Embodiment 1

[0028] Prepare the cotton root regenerative growth promoter according to the following method:

[0029] 1) Dissolve 2g of gibberellin GA3 with a purity of more than 95% in 20ml of ethanol with a volume fraction of 90%, add 0.5L of water, then add 2g of sodium naphthalene acetate with a purity of more than 95% and 1.5g of a compound with a purity of more than 95% Sodium nitrophenolate, then add 7.5g of starch, fully dissolved;

[0030] 2) Dissolve 1g of acrylamide-acrylic acid copolymer in 1.5L of water and fully dissolve;

[0031] 3) After mixing the two solutions in step 1) and step 2), stir well, and fully mix with 15kg of dry sand to make granules.

[0032] In order to verify the effect of the cotton root regenerative growth promoter of the present invention, a control group was set up at the same time: clear water, gibberellin, sodium naphthalene acetate, and sodium nitrophenolate were prepared according to the above-mentioned method by means of water-retaining agents, ad...

Embodiment 2

[0040] Prepare the cotton root regenerative growth promoter according to the following method:

[0041] 1) Dissolve 1g of gibberellin GA3 with a purity of more than 95% in 10ml of ethanol with a volume fraction of 70%, add 0.8L of water, then add 1g of sodium naphthalene acetate with a purity of more than 95% and 0.5g of a compound with a purity of more than 95% Sodium nitrophenolate, then add 5g dextrin, fully dissolved;

[0042] 2) Dissolve 0.5g of acrylamide-acrylic acid copolymer in 2.2L of water and fully dissolve;

[0043] 3) After mixing the two solutions in step 1) and step 2), stir well, and fully mix with 10kg of dry sand to make granules.

[0044] The clear water was made into granules with the help of water-retaining agent, adhesive and sand as a control group.

[0045] Experimental object: medium-early-maturing cotton genotype-Zhong 41, which is prone to premature aging, with a test area of ​​1 mu, 0.5 mu of land for each treatment, and three replicates.

[004...

Embodiment 3

[0052] Prepare the cotton root regenerative growth promoter according to the following method:

[0053] 1) Dissolve 4g of gibberellin GA3 with a purity of more than 95% in 25ml of ethanol with a volume fraction of 95%, add 1.0L of water, then add 3g of sodium naphthalene acetate with a purity of more than 95% and 2g of double nitrification with a purity of more than 95% Potassium phenate, then add 10g of starch, fully dissolved;

[0054] 2) Dissolve 1.5g of acrylamide-acrylic acid copolymer in 3.0L of water and fully dissolve;

[0055] 3) After mixing the two solutions in step 1) and step 2), stir well, and fully mix with 12kg of dry sand to make granules.

Abstract

The invention provides a cotton root regrowth-type growth promoter and a preparation method thereof. The promoter is prepared from following main components: a rooting conditioning agent, a cell excipient and gibberellin with the aid of a water-retaining agent, an adhesive, high-concentration ethanol, tap water and dry sand. The rooting conditioning agent is one or more selected from sodium naphthalene-1-acetate and sodium 3-indolebutyrate. The cell excipient is one or more selected from sodium nitrophenolate and potassium nitrophenolate. The promoter is capable of regaining cotton root activity, promoting root regrowth, promoting extension of newborn root, increasing the fertilizer utilization rate, promoting growth of the overground part, preventing premature senescence and increasing the output.

Description

technical field [0001] The invention belongs to the technical field of plant growth regulators, and relates to a growth promoter, in particular to a cotton root regenerative growth promoter and a preparation method thereof. Background technique [0002] In modern agriculture, with the development of crop production and cultivation techniques such as grain and forest trees, agricultural productivity is also constantly improving. Plant growth regulator is an exogenous non-nutritional chemical substance, which can usually be transmitted to the action site in the plant body, and can promote or inhibit certain links in the plant life process at a low concentration, making it suitable for human beings. Willing development of needs, therefore, is often used in agricultural production to regulate the production and breeding cycle of crops. [0003] According to the function of plant growth regulator, it can be divided into rooting agent, bud suppressant, anti-lodging agent, fruit p...
