Field weeding agent for planting of sweet potato in early growth stage

Abstract

The invention discloses a field weeding agent for planting of sweet potato in early growth stage. The field weeding agent is prepared from the following raw materials in parts by weight: 1 to 4 partsof 2-chloro-4-diethylamino-6-isopropylamine-1,3-5-triazine, 3 to 8 parts of sodium hexametaphosphate, 2 to 7 parts of anhydrous copper sulfate, 4 to 9 parts of cyclohexanedione compound, 2 to 6 partsof nitrophenol, 1 to 3 parts of p-phenylenediamine, 2 to 4 parts of quinclorac, 1 to 5 parts of triasulfuron, 2 to 7 parts of pendimethalin, 6 to 10 parts of soybean extracting solution, 4 to 9 partsof lactofen, and 3 to 7 parts of wetting agent. The field weeding agent has the characteristics that the degree of pollution to soil is little, any injury to crop self is almost avoided, the weeding effect is obvious, the effect is quickly taken, and the injury to a human body is avoided; compared with the traditional single preparation, the preventing effect is improved; the weeding interval andtillage interval are reduced, the labor intensity is decreased, the performance to price ratio is higher, and the like.

Description

technical field [0001] The invention relates to the field of research and development of sweet potato planting technology, in particular to a field herbicide for planting sweet potato in the initial stage of growth. Background technique [0002] The occurrence of weeds in the paddy field of direct-seeding rice usually has two peak periods. The first peak period is 5 to 7 days after sowing, generally accounting for about 60% of the total weed production, and the second peak period is 7 to 7 days after sowing. 20 days, generally accounting for about 25% of the total weed production, these two peak weed occurrence periods are the best time for weeding. There are many kinds of herbicides on the market at present, but most of them pollute the land after use, change the soil structure, and affect the taste of the crop itself; and many herbicides will damage the seedlings themselves when they are used , affecting its growth rate.
