摘要
针对人工接种肉苁蓉劳动强度大、效率低、接种率低等问题,设计了一种气吹式肉苁蓉播种机。该机可代替人工在距红柳、梭梭根部20cm处,开出60cm深、25cm宽的接种沟,并完成3层播种、覆土等作业。田间试验表明:作业速度为3km/h、气压为0.4MPa时,播种深度合格率89.6%,播种均匀性变异系数20.3%,种子破损率0,断条率0,且播种量可调,机具作业性能稳定,满足荒漠区肉苁蓉种植的农艺要求。
For artificial inoculation cistanche labor intensity , low efficiency , low inoculation rate problems , designed a kind of air blowing cistanche seeder .The machine can replace the artificial open 60 cm deep , 25 cm wide inoculation ditch away tamarisk , haloxylon roots of 20 cm, and complete the three layer of seeding , soil covering operations .Field test shows that： the operation speed is 3 km/h, pressure is 0.4 Mpa, sowing depth pass rate is 89.6%, seeding uni-formity coefficient of variation is 20.3%,the rate of seed damage is 0, the ratio of broken is 0, sowing quantity is adjust-able , the operating performance of equipment is stable , to satisfy the agronomic requirements of desert cistanche plant .
