Problems solved by technology

[0004] Under suitable climatic conditions, red leaf amaranthus grows faster and taller. Even with the above correct and effective cultivation measures, the plant height of some varieties can be close to or even exceed 2m. As a potted herbaceous landscape plant, it is easy to lodging if it is too high, and it lacks aesthetic feeling. It shortens the ornamental period, and the potted plant placement time is short, which greatly shortens its ornamental period and reduces its ornamental value and use value.

Abstract

The invention discloses an iresine herbstii short control agent and an application method thereof. The iresine herbstii short control agent is prepared from 2-(1-phenethyl sulfonyl)pyridine-N-oxide, 2-amino-6-methyl benzoic acid and sucrose in a weight mass ratio of (5.0-8.0):(1.0-4.0):(6.0-12.0), preferably 6.5:2.5:9.0; the three components are proportioned according to a weight mass ratio based on 100% purity. When in use, the short control agent is diluted according to a concentration of 70-90mg.L<-1> and then immediately sprayed. The spraying is performed late in the afternoon of a cloudy or sunny day, and it does not rain for sure within 24h since the spraying, and manual spray irrigation is not needed. 24h later, water and fertilizer are applied once, and since then, conventional fertilizer-water management and pest control are performed. The short control agent has the advantages of stable dosage form, easiness in operation, low using cost and remarkable short control effect; the components of the short control agent realize a synergistic effect; and the iresine herbstii short control agent is a good one.

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 red leaf amaranthus dwarf control agent. Background technique [0002] Amaranth ( Iresine herbstii Hook f.) is a perennial herb or subshrub of Amaranthaceae. Plant height 1-1.8m, erect stem, less branched. Stems and petioles are purplish red. Leaves are opposite, broadly ovoid to round. Margin entire, end blunt or sunken, leaf purplish red or green, with light-colored midrib and 5-6 pairs of arc-shaped lateral veins, if green or light green, with yellow veins; petiole 2-3cm long, with adnate hairs or nearly hairless. Dioecious, flowers in terminal and axillary panicles, formed by many spikes, first pilose, later almost glabrous. Bracts and bracteoles ovate, 1-1.5mm long, greenish white or yellowish white, persistent, glabrous, veinless; tiny flowers, about 1mm long, with...
