收获期对南方冬季亚麻产量和品质的影响OA
Effects of Harvest Date on the Yield and Quality of Winter Flax in Southern China
为明确纤维用亚麻在南方冬季栽培模式下的最佳收获时期,研究以主栽亚麻品种'Meline'为材料,于 2024 和 2025 年分别设置5个收获期(3月29日、4月5日、4月12日、4月19日、4月26日),系统测定了不同时期收获的亚麻原茎产量、纤维品质及相关农艺性状.结果表明:不同收获期对亚麻产量与品质具有显著影响.随着收获期推迟,原茎产量呈上升趋势,其中以 4 月 12 日收获的原茎产量最高,达 7 106.89 kg/hm2,且此时纤维品质综合评价达到一等水平,为兼顾高产与优质的适宜收获期.过早或过迟收获均导致产量或品质下降.综上,在南方冬季亚麻生产中 4 月 12 日左右为最佳收获时期,可实现产量与品质的协同提升.
To determine the optimal harvest time for fiber flax under the winter cultivation model in Southern China,this study used the main cultivated flax variety'Meline'as the material.In 2024 and 2025,flax was harvested on five dates(March 29th,April 5th,April 12th,April 19th,and April 26th).The raw stem yield,fiber quality,and related agronomic traits of flax harvested on different dates were systematically measured.The results showed that harvest date had significant effects on the yield and quality of flax.With the delay of harvest,the raw stem yield showed an increasing trend,with the highest yield observed on April 12th,reaching 7 106.89 kg/hm2.At this time,the comprehensive fiber quality reached the first class.Accordingly,April 12th was the suitable harvest date to balance high yield and quality.Harvesting too early or too late resulted in a decrease in yield or quality.In conclusion,for winter flax production in Southern China,the optimal harvest date was around April 12th,when a coordinated improvement in yield and quality could be achieved.
