Description
The technical field is as follows:
the invention relates to a herbicide and a use method thereof, in particular to a herbicide for closing soil in a direct seeding beet field and a use method thereof.
Background art:
beet is an important sugar-making raw material in China and also one of the main economic crops. In the process of planting the beet, weeds are easy to grow in a beet field, and the growth of the weeds influences the growth of the beet, so that the yield of the beet is reduced, and therefore, the weed control becomes a great problem to be solved urgently in beet production.
The main weeds in the beet field comprise barnyard grass, crabgrass, moleplant seed, green bristlegrass herb, goosegrass herb, polygonum, amaranth, purslane, cyperus rotundus, deformed cyperus rotundus and the like. Generally, a chemical weeding mode is adopted, soil closed weeding is carried out before sowing, weed sprouts in soil can be effectively killed by the soil closed weeding before sowing, the weed germination rate is reduced, and the weeding composition is an important control means for reducing the growth of weeds in a beet field. At present, closed weeding of soil before seeding in a beet field has certain limitations, for example, 960 g/L of Jindu can effectively prevent and control gramineous weeds and dicotyledonous weeds, the prevention and control rate of the gramineous weeds is 87%, and the prevention and control rate of the dicotyledonous weeds reaches 72%; the 720 g/L metolachlor can effectively prevent and control monocotyledonous weeds, and the monocotyledonous weed prevention and control rate reaches more than 82 percent. The common herbicide for soil sealing, pendimethalin, is forbidden for beet planting because of easy phytotoxicity to beet. Therefore, the existing common herbicides have certain control limitations, cannot simultaneously play a good control effect on main weeds in the beet fields, and cause low soil sealing weeding efficiency before sowing; in order to improve the weeding efficiency, the soil sealing can be carried out repeatedly, which wastes time and labor.
The invention content is as follows:
the invention aims to provide a herbicide for closing soil in a direct seeding beet field, which has low control limitation and high control efficiency.
The second purpose of the invention is to provide a use method of the herbicide for sealing the soil of the direct seeding beet field, which has low control limitation and high control efficiency.
The first purpose of the invention is implemented by the following technical scheme: the direct seeding beet field soil sealing herbicide comprises the following components in percentage by mass: 70-72% of 96% of golden Du missible oil and 28-30% of 33% of pendimethalin missible oil; and uniformly mixing the 96% of the golden Du emulsifiable concentrate and the 33% of the pendimethalin emulsifiable concentrate to obtain a finished herbicide product.
96% of Jindu emulsifiable concentrate is a commercial Jindu common preparation formulation, and each liter of emulsifiable concentrate contains an effective component of fine-metolachlor (C)15H22ClNO2)960 g. The 96% Jindu emulsifiable concentrate is a selective preemergence herbicide, and plays a role in killing weeds mainly through bud sheaths and buds of germinated weeds.
The 33% pendimethalin emulsifiable concentrate is a common dosage form of commercialized pendimethalin, and each liter of the pendimethalin emulsifiable concentrate contains an effective component pendimethalin (C)13H19N3O4)330 g. The 33% pendimethalin emulsifiable concentrate is a selective preemergence and postemergence dry field soil treatment herbicide. Weeds absorb the agent through the germinating sprouts, and the agent entering the plant body binds to tubulin to inhibit mitosis of plant cells, thereby causing death of the weeds.
Further, the mass percent of 96 percent of the Jindou missible oil is 72 percent, and the mass percent of 33 percent of the pendimethalin missible oil is 28 percent.
The second purpose of the invention is implemented by the following technical scheme: the application method of the herbicide for closing the soil of the direct-seeding beet field comprises the following steps:
s1, preparing a herbicide: the herbicide comprises the following components in percentage by mass: 70-72% of 96% of golden Du missible oil and 28-30% of 33% of pendimethalin missible oil; uniformly mixing the 96% of the golden Du emulsifiable concentrate and the 33% of the pendimethalin emulsifiable concentrate to obtain a finished herbicide product;
s2, diluting the herbicide: uniformly mixing the herbicide, and adding water for dilution, wherein the volume ratio of the herbicide to the water is 0.1: 15, obtaining a diluted herbicide;
s3, herbicide spraying: after the direct seeding beet field is sowed and before the emergence of seedlings, the diluted herbicide is uniformly sprayed on the soil surface of the direct seeding beet field, and the spraying amount is 15.1L/mu.
Further, the herbicide is diluted within 4 hours after the preparation of the diluted herbicide, and the diluted herbicide is sprayed immediately after the preparation of the diluted herbicide.
Further, the mass percent of 96 percent of the Jindou missible oil is 72 percent, and the mass percent of 33 percent of the pendimethalin missible oil is 28 percent.
The invention has the advantages that: 1. breaks through the limitation that pendimethalin is forbidden in a beet field, improves the soil closed weeding effect of a direct seeding beet field, has the control effect on gramineous weeds of 100 percent and dicotyledonous weeds of more than 95 percent, and has higher control effect on various monocotyledonous weeds and part of annual dicotyledonous weeds. 2.
