preparation example Construction

[0048] The preparation method of above-mentioned a kind of cotton planting regulator, comprises:

[0049] Weigh the type A plant regulator and the type B plant conditioner according to the requirements in each growth period of cotton respectively;

[0050] The type A plant regulator and the type B plant conditioner that are weighed are fully mixed in the solvent;

[0051] Optionally, the weighed Type A and Type B preparations are respectively dissolved in a solvent, and fully mixed evenly;

[0052] Optionally, dissolve the pendimethalin, flumetriamine, and rimsulfuron-methyl in the weighed Type A and Type B plant preparations respectively in a solvent, and then fully mix them uniformly;

[0053] Optionally, the solvent includes but not limited to water.

[0054] The preparation method of the cotton planting conditioner of the invention has simple process and is suitable for large-scale preparation.

[0055] The use method of above-mentioned a kind of cotton planting regulat...

Embodiment 1

[0062] The cotton plant regulator provided in this example is composed of type A plant regulator applied at the budding stage, initial flowering stage and full bloom stage of cotton respectively, and type B plant regulator applied only at the full bloom stage of cotton. The active ingredient of the Type A plant regulator is chlormequat, and the Type B plant regulator active ingredient includes the following components:

[0063] a) pendimethalin,

[0064] b) Methetine,

[0065] c) rimsulfuron-methyl.

[0066] Apply 0.25g / mu of the type A plant regulator in terms of the active ingredient chlormequat at the budding stage of cotton, and apply 0.5g / mu of the type A plant regulator in terms of the active ingredient chlormequat at the initial flowering stage of cotton. The A-type plant regulator is applied at the flowering stage at 1 g / mu in terms of the active ingredient chlormequat. At the same time, it is necessary to apply the Type B plant regulator at the full flowering stage...

Embodiment 2

[0071] The cotton plant regulator provided in this example is composed of type A plant regulator applied at the budding stage, initial flowering stage and full bloom stage of cotton respectively, and type B plant regulator applied only at the full bloom stage of cotton. The active ingredient of the Type A plant regulator is chlormequat, and the Type B plant regulator active ingredient includes the following components:

[0072] a) pendimethalin,

[0073] b) Methetine,

[0074] c) rimsulfuron-methyl.

[0075] Apply 0.5g / mu of the type A plant regulator in terms of the active ingredient chlormequat at the budding stage of cotton, and apply 1g / mu of the type A plant regulator in terms of the active ingredient chlormequat at the early flowering stage of cotton. The type A plant regulator is applied at 2 g / mu in terms of the active ingredient chlormequat. At the same time, it is necessary to apply the type B plant regulator at the full flowering stage of cotton, and the weight r...

Abstract

The invention relates to the technical field of plant growth regulators, in particular to a cotton plant regulator and a preparation and use method thereof, which are mainly used for regulating and controlling cotton growth. The invention discloses a cotton plant regulating agent for the first time. The agent is composed of an A-type plant adjusting agent applied in a squaring stage, an initial flowering stage and a full-bloom stage of cotton and a B-type plant adjusting agent applied only in the full-bloom stage. The cotton plant regulator has excellent effects of inhibiting excessive growthof cotton, promoting maturation of cotton bolls, increasing boll opening and increasing yield, can improve the quality of cotton fibers to a certain extent, is safe to cotton and does not influence the growth of succeeding crops. The preparation and use methods of the cotton plant regulator are simple in process, the corresponding regulators are applied in different growth periods of cotton respectively, excessive growth of the cotton can be effectively inhibited, cotton boll maturation is promoted, the cotton yield and quality are improved, and economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of plant growth regulators, in particular to a cotton plant regulator and its preparation and use methods. Background technique [0002] Chlormequat is a synthetic plant growth regulator. Its main function is to inhibit plant cell elongation without affecting cell division. It was first discovered and applied to solve the problem of excessive cotton growth. Chlormequat has remarkable effects in shaping cotton plant shape, preventing crazy growth, improving ventilation and light transmission conditions, and enhancing photosynthesis, and can increase the flowering rate and flowering yield before frost. However, cotton is sensitive to chlormequat, and its usage and dosage are difficult to control. Excessive dosage or excessive use times will pose a threat to cotton yield and quality, and it is difficult to grasp its best use period and dosage based on experience. There is not yet a clear standard to regulate a...
