Salvia splendens flowering promoter and application method thereof

Abstract

The invention discloses a bunch of red flowering accelerator and a use method thereof. The bunch of red flowering accelerator is composed of O,O-dimethyl-S-[(4-carbonyl-1,2,3-benzene Triazine-3(4H-yl)-methyl]phosphorodithioate, β-hydroxyethylhydrazine, and sucrose are compatible, and the weight-to-mass ratio of the three components is 4.0-5.0:2.0-3.0: 6.0 to 8.0, the preferred ratio is 4.5:2.5:7.0, and the three components are calculated according to the weight to mass ratio of 100% purity. When in use, dilute it at a concentration of 600-700 mg.L‑1 and spray it immediately. The operation should be carried out in the evening on cloudy or sunny days. After spraying, it is guaranteed that there will be no rain within 24 hours, and artificial sprinkler irrigation will not be carried out during this period. After 24 hours, apply water and fertilizer once, and carry out routine fertilizer and water management and pest control after spraying. The dosage form of the preparation is stable, easy to operate, low in use cost, and has a remarkable effect of promoting flowering. The single agents in the preparation have synergistic effects, and are a good flowering accelerator for a string of reds.

Description

technical field [0001] The invention belongs to the development and application of new agricultural practical technologies, and relates to a method for the development, production and application of a string of red flowering accelerators. Background technique [0002] a bunch of red ( Salvia splendens Ker-Gawler) is a subshrub-like herb of the Lamiaceae Salvia genus, up to 90cm high. Stems obtusely quadrangular, with shallow grooves, glabrous. Leaves are oval or triangular-ovate, 2.5-7cm long, 2-4.5cm wide, apex acuminate, base truncated or round, blunt, with serrated edges, green above, pale below, glabrous on both sides , glandular point below; cauline leaf petiole 3-4.5cm long, glabrous. Verticels 2-6 flowers, forming a terminal raceme, inflorescences 20cm or more long; bracts ovoid, red, wrapping flower buds before blooming, apex caudate acuminate; pedicels 4-7mm long, Densely reddish glandular pilose, rachis puberulent. Calyx bell-shaped, red, about 1.6cm long when...

Problems solved by technology

[0004] As a landscape plant, a bunch of reds often have top buds that are difficult to open. Even if the potted flowers that have been used up and discarded still have a large number of unopened top buds, so the top buds are often picked in cultivation measures to improve its ornamental value, and often due to the new buds in the middle and late stages. Less occurrence leads to fewer new branches and new flowers, which seriously reduces its production performance and practical value
