Fuente: WIPO "hemp" The invention relates to a field standing degumming agent for hemp stems for fibers, and the degumming agent comprises glyphosate and one or more of ethyl trichloropyr, 2-methyl-4-chloro-phenoxyacetate and 2, 4-drops, preferably comprises glyphosate and ethyl trichloropyr, or comprises glyphosate and 2-methyl-4-chloro-phenoxyacetate, or comprises glyphosate and 2, 4-drops. The invention relates toa field standing degumming process method for hemp stems for fibers, which adopts an agricultural unmanned aerial vehicle to spray a degumming agent to standing hemp plants in a target hemp field inthe mature period of the process of hemp for fibers, and harvests the standing hemp plants as soon as possible after reaching the degumming end point, and changes the traditional mode of firstly harvesting and then degumming in the prior art, and subsequent processing can be directly carried out after harvesting; dry stem degumming is uniform, color and luster are consistent, and processed fibersare good in quality. Meanwhile, the degumming agent and the degumming process method thereof further have the advantages of being simple in formula, simple in process, easy and convenient to operate and easy to implement, large-area application and popularization are facilitated, and upgrading of the hemp degumming technology is promoted.
