Herbicide for economic forest of metasequoia and preparation method thereof

Abstract

The invention discloses a herbicide for an economic forest of metasequoia. The herbicide comprises the following components by mass: 30-40 parts of imazamox, 12-18 parts of lignosulfonate, 3-6 parts of Chinese honeylocust fruit powder, 5-9 parts of silkworm excrement, 10-13 parts of soapberry powder, 3-5 parts of ammonium sulfate, 2-5 parts of aluminum chloride, 3-6 parts of citric acid, 18-22 parts of cloransulam-methyl succinate, 6-13 parts of calcium dodecylbenzene sulfonate, 4-9 parts of urea and 20-30 parts of diatomite. The herbicide of the invention has higher control effect than off-season control effect and a wide herbicidal spectrum, can effectively prevent and eliminate grassy weeds and broadleaf weeds at the same time, reduces the use amount of pesticides, and is shortened in time needed for taking effect and free of harm to metasequoia seedlings.

Description

technical field [0001] The invention relates to a herbicide, in particular to an economic forest metasequoia herbicide and a preparation method thereof. Background technique [0002] Cedar tree, also known as sand tree, sand tree, etc., belongs to Pinaceae, fir tree, up to 30 meters high, diameter at breast height can reach 2.5-3 meters, grayish brown bark, nearly round winter buds, cone-shaped male cones, female The cones are solitary, the cones are oval, 2.5-5 cm long, and 3-4 cm in diameter. Weeds in the base of fir seedlings are common and there are many types, mainly gramineous weeds and annual broad-leaved weeds, weeds Competing with fir saplings for fertilizer and water, resulting in slow growth of fir saplings. Artificial weeding and chemical weeding are the most commonly used weeding methods at present, but manual weeding is not suitable for large-scale planted Chinese fir. Therefore, for large-scale planted Chinese fir, people generally Chinese fir herbicides are ...

[0002] Cedar tree, also known as sand tree, sand tree, etc., belongs to Pinaceae, fir tree, up to 30 meters high, diameter at breast height can reach 2.5-3 meters, gray-brown bark, nearly round winter buds, cone-shaped male cones, female The cones are solitary, the cones are oval, 2.5-5 cm long, and 3-4 cm in diameter. Weeds in the base of fir seedlings are common and there are many types, mainly gramineous weeds and annual broad-leaved weeds, weeds Competing with fir saplings for fertilizer and water, resulting in slow growth of fir saplings. Artificial weeding and chemical weeding are the most commonly used weeding methods at present, but manual weeding is not suitable for large-scale planted Chinese fir. Therefore, for large-scale planted Chinese fir, people generally Chinese fir herbicides are used for chemical weeding, but the herbicides cause serious harm to the ecological environment and affect the quality of fir trees
