不同大麻品种（系）在西双版纳州种植的适应性观察

【目的】筛选出适合西双版纳州勐海县种植的大麻品种（系），为西双版纳州云麻产业健康、持续和稳定发展奠定坚实的基础。【方法】以云麻5号、云晚6号、云晚9号、云晚10号、皖大麻1号、汾阳1号、PB-1、PB-2、PB-3、PB-4、PB-5、云麻1号（CK）12个品种为试材，观测各品种（系）的物候期，在收获期测定各品种（系）的经济性状、纤维产量、纤维的化学成分等项目。【结果】工艺成熟期最晚的品种为PB-3，最早的品种为汾阳1号，两者相差70 d；PB-3的纤维产量最高，为2694.0 kg/ha，但纤维品质稍差；云晚6号和云麻5号的综合性状较好；云麻1号（CK）、云晚10号、云晚9号、和PB-4纤维产量稍低，分别为2221.5、2110.5、1944.0和1914.0 kg/ha；其他品种（系）的产量均较低。【结论】云晚6号、云麻5号和PB-3适宜在西双版纳州勐海县推广种植，而云麻1号、云晚10号、云晚9号和PB-4的纤维产量较高，为次适宜推广种植品种，其他品种（系）纤维产量较低，不宜在西双版纳州勐海县推广种植。

Adaptability of different hemp varieties(lines) in Xishuangbanna Prefecture

Objective]The present experiment was conducted to select suitable cultivar for planting in Menghai region of Xishuangbanna in order to sustainably develop hemp industry in this area.Method]Phenophases,agronomic traits,fiber production and fiber chemical composition of hemp varieties,viz.,Yunma 5,Yunwan 6,Yunwan 9,Yunwan 10,Wandama 1,Fenyang 1,PB-1,PB-2,PB-3,PB-4,PB-5 and Yunma 1(CK) were investigated.Result]The longest technical maturity period of PB-3 was found 70 days higher than Fenyang 1.PB-3 had the highest fiber yield(2694.0 kg/ha) but a little poor fiber quality.Comprehensive traits of Yunwan 6 and Yunma 5 were relatively fine.Yunma 1(CK),Yunwan 10,Yunwan 9 and PB-4 had relatively lower fiber yield which was 2221.5,2110.5,1944.0 and 1914.0 kg/ha,respectively.The yield of other varieties was low.Conclusion]Yunwan 6,Yunma 5 and PB-3 were found suitable for planting in Menghai County,followed by Yunwan 10,Yunwan 9,and PB-4 being good for higher fiber yield.The other varieties with lower fiber yield should not be planted in this region.
