13个纤用工业大麻黑龙江第三积温带的比较试验及适应性分析

为了筛选出适宜黑龙江省种植的纤维用工业大麻品种,2019年对13份黑龙江省当地主栽工业大麻品种进行品种比较试验,对各品种田间农艺性状进行综合比较研究。结果表明:各个纤维用的引进品种纤维产量由高到低顺序为:新麻1号>庆麻7号>中麻18号>中麻13号>汉麻10号>火麻1号>庆麻5号>庆麻6号>龙麻7号>中麻1号>汉麻12号>汉麻1号>庆麻2号。5个品种的纤维产量均高于对照火麻1号(ck),其中新麻1号表现最好,纤维产量为1.992 t/hm²,庆麻7号、中麻18号稍低于新麻1号,三者显著高于对照火麻1号。庆麻5号、庆麻6号、龙麻7号纤维产量低于对照品种火麻1号,但差异不显著。中麻1号、汉麻12号、庆麻2号纤维产量显著低于对照火麻1号。另外由于在试验过程中发现汉麻10号抗病性较弱,龙麻7号抗倒性较弱,增加了种植成本和风险,所以不推荐在黑龙江第三积温带种植,其余品种均适宜在黑龙江第三积温带地区种植。

Comparative Experiment and Adaptability Analysis of 13 Industrial Hemp Used in the Third Cumulative Temperate Zone of Heilongjiang Province

In order to screen out the industrial hemp varieties suitable for cultivation in Heilongjiang Province,13 main industrial hemp varieties planted in Heilongjiang province were compared in 2019,and the agronomic traits of each variety in the field were comprehensively compared.The results showed that the fiber yield of the introduced varieties in the order from high to lowwas:Xinma 1>Qingma 7>Zhongma 18>Zhongma 13>Hanma 10>Hanma 10>Huoma 1>Qingma 5>Qingma 6>Longma 7>Zhongma 1>Hanma 12>Hanma 1>Qingma 12.The fiber yield of the five varieties was higher than that of the control Huoma 1(CK),among which Xinma 1 had the best performance,with fiber yield of 1.992 t/hm²;Qingma 7 and Zhongma 18 were slightly lower than that of Xinma 1,and the three were significantly higher than that of the control Huoma 1.The fiber yield of Qingma 5,Qingma 6 and Longma 7 was lower than that of the control variety,but the difference was not significant.The yield of Zhongma 1,Hanma 12 and Qingma 2 fiber was significantly lower than that of the control Huoma 1.In addition,Hanma 10 with weak resistance to disease and Longma with weak lodging resistance were not recommended to plant in the third accumulation zone of Heilongjiang for it would increase the cost and risk of planting.The other varieties were suitable for planting in the third accumulation temperate zone of Heilongjiang.
