为了发展我国苎麻优势,针对生产上品种“多、乱、杂”和原麻品质下降的问题,笔者于1987年首先提出了“苎麻品种区域化”的建议,在湖南省政府的变持下,由湖南农学院苎麻研究、湖南省经济作物局主持,与上海市农科院作物研究所及湖南省10个苎麻纺织原料基地县等单位协作,开展了本项的研究,1979～1984年,相继研究成功切芽繁殖、腋芽繁殖、嫩梢繁殖和试管苗繁殖等一整套快速无性繁殖新技术,繁殖系数可达100倍,1000倍和10000倍;并采用边研究、边示范、边推广措施,短期内取得了明显的经济效益,据湖南省9个基地县统计,1984～1985年按品种区域化的要求新扩苎麻面积2.4×10~5多亩,其中切芽繁殖16.69×10~5亩,按市场价格计算,农业经济效益1.3×10~3元。此外,由于推广品种区域化种植,提高了纺织品质量,工业每年增收6.16×100元和创汇4.8×100~6美元。
In order to develop the advantage of ramie in our country, aiming at the problem of “more, chaos, miscellaneous” and the decline of quality of raw ramie, the author first proposed the proposal of “ramie variety regionalization” in 1987. Under the change of the Hunan provincial government, The research was conducted by ramie research of Hunan Agricultural College and Hunan Provincial Economic Crops Bureau in collaboration with the Crop Research Institute of Shanghai Academy of Agricultural Sciences and the 10 ramie textile base counties in Hunan Province. From 1979 to 1984, A series of new rapid clonal propagation techniques such as cutting bud propagation, axillary bud multiplication, shoot shoot propagation and in vitro plantlet propagation were studied. The multiplication coefficients were 100 times, 1000 times and 10000 times, respectively. In the short term, significant economic benefits have been achieved. According to the statistics of 9 counties and counties in Hunan Province, from 1984 to 1985, the area of new ramie expanded 2.4 × 10 ~ 5 mu according to the regionalization of cultivars, in which the cutting buds multiplied by 16.69 × 10 ~ 5 mu According to the market price, the agricultural economic benefit is 1.3 × 10 ~ 3 Yuan. In addition, due to the promotion of regional planting varieties, improve the quality of the textile industry, an annual increase of 6.16 × 100 yuan and foreign exchange earnings 4.8 × 100 ~ 6 dollars.
