Plant growth regulator mixing chlormequat chloride and paclobutrazol

Abstract

The invention discloses a plant growth regulator mixing chlormequat chloride and paclobutrazol, which is formed by compounding chlormequat chloride, paclobutrazol, an additive and a filler, wherein the mass ratio of chlormequat chloride and paclobutrazol is 1:1-20:1, the content of chlormequat chloride and paclobutrazol in the mixture is 1%-60%, and the content of the additive and the filler in the mixture is 99%-40%. The plant growth regulator can be processed into soluble powder, dispersible granules, dispersible tablets and effervescent tablets. The plant growth regulator mixing chlormequat chloride and paclobutrazol is used for controlling overgrowth of crops, increasing yield of the crops and improving quality of the crops.

Description

technical field

[0001] The invention relates to a plant growth regulator, in particular to a mixed plant growth regulator compounded by chlormequat and paclobutrazol. technical background

[0002] Chlormequat is an antagonist of gibberellin, which can enter the plant through leaves, twigs, buds, roots and seeds to control the excessive growth of the plant, promote reproductive growth, shorten the internodes of the plant, and make the plant short and strong. , thick, well-developed root system, lodging resistance, enhanced photosynthesis, increase the fruit setting rate of certain crops, improve quality and increase yield. Chlormequat is a highly active plant growth regulator. When it is applied to the environment, it will be quickly degraded by microorganisms and light in the soil. The residual effect period is short, and some crops need to be used multiple times during the growth period.

[0003] Paclobutrazol (diethyl aminoethyl hexanoate) is also an antagonist of gibbere...

Examples

Embodiment 1

[0013] 50 kg of chlormequat, 10 kg of paclobutrazol, 0.5 kg of sodium lauryl sulfate, 1 kg of sodium lignosulfonate, 100 kg of white carbon black, crushed and mixed to make 60% chlormequat-paclobutrazol wettability powder.

Embodiment 2

[0015] 50 kg of chlormequat, 10 kg of paclobutrazol, 4 kg of sodium lignosulfonate, 10 kg of 20% sodium carboxymethyl cellulose aqueous solution, 10 kg of urea, 10 kg of bentonite, 5 kg of white carbon black, calcium chloride to 100 kg Kilogram. Pass chlormequat, paclobutrazol, sodium lignosulfonate, bentonite, white carbon black, urea, and calcium chloride through a 200-mesh sieve, mix with 20% sodium carboxymethylcellulose aqueous solution, extrude and granulate, and dry. Prepare 60% chlormequat-paclobutrazol water-dispersible granules.

Embodiment 3

[0017] 50 kg of chlormequat, 10 kg of paclobutrazol, 4 kg of sodium lignosulfonate, 10 kg of 20% sodium carboxymethyl cellulose aqueous solution, 10 kg of urea, 10 kg of bentonite, 5 kg of white carbon black, calcium chloride to 100 kg Kilogram. Pass chlormequat, paclobutrazol, sodium lignosulfonate, bentonite, and white carbon black through a 200-mesh sieve, mix with 20% sodium carboxymethylcellulose aqueous solution, and granulate through a swing granulator (or extrusion granulation machine), the particle size is between 0.5 and 3mm, and dried for later use; pass urea and calcium chloride through a 200-mesh sieve, mix with the above particles, and make 60% chlormequat-paclobutrazol water-dispersible tablets through a tablet machine.
