摘要: 为探索不同栽培密度对苎麻(Boehmeria nivea L.)的影响,以华苎4号为材料,于2018年以15 000、10 000、8 000、6 000、4 000株/667 m2密度进行移栽。结果表明,不同密度对产量有影响,但无规律;二龄麻比三龄麻产量低,头麻产量高于二麻;通过对不同的处理进行缺蔸调查,不同密度缺兜率随着时间的推移逐渐提高,到2020年基本稳定在6.5蔸/m2,密度稳定在4 000蔸/667 m2

关键词: 苎麻(Boehmeria nivea L.), 不同密度, 合理种植, 生产现状, 产量

Abstract: In order to explore the effect of different planting densities on ramie (Boehmeria nivea L.), Huazhu No.4 was transplanted at the density of 15 000, 10 000, 8 000, 6 000 and 4 000 plants/667 m2 in 2018. The results showed that different densities had an effect on yield, but there was no regularity. The yield of second-age hemp was lower than that of third-age hemp, and the yield of first-age hemp was higher than that of second-age hemp. Through the investigation of different treatments, the missing rate of different densities gradually increased with time, and it was basically stable at 6.5 clumps/m2 by 2020, and the density was stable at 4 000 clumps/667 m2.

Key words: ramie (Boehmeria nivea L.), different density, reasonable planting, production status, yield
