Herbicide for medicinal Xanthium sibiricum and preparation method of herbicide

Abstract

The invention discloses a herbicide for medicinal Xanthium sibiricum, comprising the following components in parts by mass: 20-32 parts of acetochlor emulsifiable concentrate, 18-32 parts of imazamox,12-16 parts of ginkgo leaf extract, 4-8 parts of lignin, 2-4 parts of indole acetic acid, 8-14 parts of sodium hydrogencarbonate, 5-9 parts of menthol, 4-7 parts of nicoteine, 3-7 parts of diatomaceous earth, 5-8 parts of white carbon black, 9-12 parts of agricultural rare earth, and 4-6 parts of light calcium carbonate. The herbicide of the invention can effectively inhibit weed growth in a Xanthium sibiricum planting area, and ensure the growth environment of Xanthium sibiricum, and uses a large number of plant extract preparations and auxin without affecting the medicinal value of Xanthiumsibiricum.

Description

Technical field [0001] The invention relates to a herbicide, in particular to a medicinal cocklebur herbicide and a preparation method thereof. Background technique [0002] Cocklebur, an annual herb, 20 to 90 cm high. Root fusiform, branched or unbranched. The stems are erect without branches or rarely branched, the lower part is cylindrical, 4-10 mm in diameter, and the upper part is longitudinally furrowed, covered with grayish white rough hair, triangular-ovate or heart-shaped leaves, 4-9 cm long and 5-10 wide. Centimeters, nearly entire, or 3 to 5 inconspicuous lobes, pointed or blunt at the top, slightly heart-shaped or truncated at the base, an equal wedge at the junction of the petiole, with irregular thick serrations on the edge, with three bases The veins and lateral veins are arc-shaped and reach the leaf margin. The veins are densely covered with strigella, green on the top, and pale underneath, covered with strigella. The petiole is 3-11 cm long, widely distributed...

AI Technical Summary

Problems solved by technology

Stem erect without branches or few branches, cylindrical in the lower part, 4-10 mm in diameter, longitudinally grooved in the upper part, covered with gray-white strigose, leaves triangular-ovate or heart-shaped, 4-9 cm long, 5-10 wide cm, nearly entire, or with 3 to 5 inconspicuous lobes, apex pointed or blunt, base slightly cordate or truncate, forming an equal wedge at the junction with petiole, margin with irregular coarse serrations, and three bases Veins, lateral veins arc-shaped, straight to the leaf edge, densely strigose on the veins, green above, pale below, strigose, petiole 3-11 cm long, widely distributed in northeast, north, east, south, northwest And the southwestern provinces and regions, the former Soviet Union, Iran, India, North Korea and Japan are also distributed, but during the planting process of cocklebur, the growth of weeds obtains the nutrients in the planting area of ​​cocklebur, resulting in malnutrition of cocklebur plants and reduced yield. It will also increase the risk of pest infestation, causing economic losses and human resource consumption
