Experimental Verification Report on UAV Seeding of Forage Seeds
In order to verify the effect of using seeding UAVs to spread forage grass seeds for improving natural grasslands,we collected the on-site measured data of using UAVs to spread forage grass seeds in the vegetation restoration projects,grass and livestock husbandry projects,desertified grassland treatment projects and grazing withdrawal and grassland restoration projects in Ganzhou District from May 2019 to June 2020.The experimental re-sults show that the average error value of seed-falling density in 15 quadrats selected in the four aerial seeding pro-jects is 15.52%,and the error of seed-falling density of single Elymus dahuricus is higher than that of Elymus dahuricus mixed with other grass species.The overall technical indicators meet the requirements of relevant techni-cal regulations,which verifies the feasibility and effectiveness of using seeding UAVs to spread forage grass seeds for improving natural grasslands.Seeding UAVs can be used as a new technical means for spreading forage grass seeds in the treatment of grassland ecological restoration.
