五个工业大麻品种在黑龙江省半山区种植的适应性评价

Adaptability Evaluation of Five Industrial Hemp Varieties Planting in Semi-Mountainous Areas of Heilongjiang Province

为筛选适合黑龙江省半山区种植的籽用工业大麻品种,试验在相同栽培条件下,对5个大麻品种的主要生育期、出苗情况、植株和籽粒性状、产量进行比较分析。结果表明,5个品种的生育期表现为早熟、中早熟;出苗、保苗率均较高;植株繁茂、各项性状指标均符合籽用工业大麻的生产标准;成熟后对照品种龙大麻1号千粒重极显著低于其他品种;籽粒产量最高的是龙大麻6号,为1116.8 kg·hm^(-2),其次是汉麻9号,为1074.7 kg·hm^(-2),均显著高于对照,这两个品种更适合在黑龙江省绥棱半山区大面积种植。

In order to screen industrial hemp varieties suitable for planting in the semi-mountainous areas of Heilongjiang Province,the main growth period,emergence,plant and grain characters and yield of five hemp varieties were compared and analyzed under the same cultivation conditions.The results showed that the growth period of five varieties showed early maturity and middle maturity;The emergence rate and seedling preservation rate were both high;The plants were luxuriant,and all the characters were in line with the production standards of industrial hemp for seeds.The comparison of mature grain characters showed that the 1000-grain weight of the control variety Longdama 1 was significantly lower than that of other varieties.The grain yield of Longdama 6 was the highest,which was 1116.8 kg·ha^(-1),followed by that of Hanma 9,which was 1074.7 kg·ha^(-1).The yields of these two varieties were significantly higher than those of the control varieties.The results showed that they were more suitable for large-scale planting in the semi-mountainous of Suiling,Heilongjiang Province.
