摘　　要：为探索苎麻年收三季改为年收四季种植技术对纤维产量及纤维支数的影响,以"中苎1号"为研究对象,通过2015年试验,2016、2017年两年示范。结果表明:全年收四季技术相对收三季技术,3年间纤维产量每公顷分别增产439. 5、367. 5、315. 0 kg,增幅分别达18. 7%、16. 3%、14. 3%,增产效果明显,但年收四季麻增加了多收一季麻的劳务和10%的肥料投入;纤维支数3年间分别提高293. 4、233. 1、218. 6 m/g,均达到1800 m/g以上,提高幅度明显且稳定。In order to explore the effect of planting technology of ramie changing from three harvest to four harvest on ramie fiber yield and quality,Zhongzhu No. 1 was selected as the research object and was studied in 2015,2016 and 2017. Results showed that with the technology of four harvest times the annual fiber yields of ramie increased significantly comparing with that of three harvest times: the annual fiber yield per hectare enhanced to 439. 5 kg in 2015,367. 5 kg in 2016 and 315. 0 kg in 2017,with an increasement of 18. 7%,16. 3% and 14. 3% respectively. However,four harvests a year will cost higher workload and 10% more fertilizer input. Over the past three years,fiber fineness was improved by293. 4 m/g,233. 1 m/g and 218. 6 m/g,respectively,reaching more than 1800 m/g,with a significant and stable increase.
