Description
Summary:To resolve the bottleneck problems hindering the development of the ramie (Boehmeria nivea L. Gaud) cultivation industry, the feasibility of a new harvesting mode was investigated. This allows a continuous supply of ramie within a growing season and provided theoretical and technical support for industrialized production of ramie. Huazhu 4 was used and harvesting times were within 28 May to 21 October 7 days interval. Five harvesting modes were designed with 3 replications, with traditional harvesting mode as the control. The results showed that the range in fiber fineness among the five harvesting modes was 1659-1958 m/g. The mean in mode 1 was the highest of the five modes (1958 m/g) and was 6.47% higher than in controls. Compared to controls, the average fiber fineness in mode 5 was 1.96% higher, and that of mode 4 was the same as the controls. However, modes 2 and 3 had 9.79 and 5.55% lower mean fiber fineness compared with controls, respectively. The harvested yields of raw fiber in modes 2 and 3 were 21.50 and 5.04%, respectively higher than controls - with no increases in other modes. This suggested that 1-30 June was the most suitable time for continuous harvesting producing higher yields. The latest that ramie should be harvested is mid-late October. Continuous harvesting mode was feasible for ramie production, and provides a novel harvesting method for perennial crop, which is mainly harvested from nutritive organs.
