Embodiment 1

[0045] Take 0.0003 kg of brassinolide BR1 (purity is 30%), 0.1 kg of vitamin B1, add isopropanol, Nongru No. 600 and water, mix and stir evenly, and make an aqueous solution so that the mass fraction of active ingredients is 0.01 %.

[0046] The product is diluted to an active ingredient concentration of 75ppm, sprayed during the cucumber flower bud differentiation stage, the active ingredient application rate of the preparation is 22.5g / mu / time, sprayed once, and measures its output. The results showed that the average yield of cucumbers increased by 15-20%.

Embodiment 2

[0048] Take 0.09 kg of brassinolide BR2 (purity is 55%), 80 kg of vitamin B2, add sodium carboxymethyl cellulose and sodium lignosulfonate, mix well, extrude and granulate, dry to make water dispersion Granules, so that the active ingredient mass fraction is 90%.

[0049] The product is diluted to an active ingredient concentration of 100ppm, sprayed during the rice growth period, and the active ingredient application rate of the preparation is 3.5g / mu / time, sprayed once, and measures its output. The results showed that the average yield of rice increased by 15% to 25%.

Embodiment 3

[0051] Take 0.001 kg of brassinolide BR3 (purity is 48%), 50 kg of vitamin B3, add sodium lignosulfonate, sodium lauryl sulfate and mix well, and prepare soluble powder, so that the mass fraction of active ingredients is 0.001 %.

[0052] This product is dissolved in water, and be diluted to active ingredient concentration and be 2ppm, spray when grape fruit enlargement stage, active ingredient application rate is 60g / mu / time, spray once, measure its output. The results showed that the average yield increased by 10% to 15%, the soluble solids increased by about 0.6%, and the sugar content increased by about 0.9%.

Abstract

The present invention relates to a plant growth regulator and applications thereof, particularly to a double-component compounding plant growth regulator adopting brassinolide and vitamin as active components. The technical problem solved by the invention is to provide a low-cost plant growth regulator. The active components of the plant growth regulator of the present invention comprise, by weight, 0.0001-0.1 part of brassinolide and 0.1-80 parts of vitamin, wherein the vitamin is at least one selected from vitamin B and vitamin D. The plant growth regulator of the present invention has characteristics of significant plant growth regulation effect, crop yield increasing, low cost, safe use, and wide use concentration range, and provides the substantially-reduced drug hazard risk compared with the single use of the plant hormone.

Description

technical field [0001] The invention relates to a plant growth regulator and an application thereof, in particular to a dual compound plant growth regulator with brassinolide and vitamins as effective components. Background technique [0002] Brassinolide, the common name in English, is brassinolide, which has low toxicity to humans and animals, and is recognized by the academic circles as the sixth class of plant hormones. Nearly 40 species have been found, of which only a few have high biological activity and practical value. Its chemical structural formula is: [0003] [0004] [0005] Brassinolide can be used in field crops, fruits, vegetables, flowers, etc. It has multiple functions such as strong rooting, growth promotion, seedling lifting, strong seedlings, seedling preservation, yellow leaf disease leaves turning green, promoting fruit set and fruit expansion and early maturity, reducing disease and phytotoxicity, coordinating nutritional balance, drought re...
