天水生态条件下不同大麻品种（系）产量及株高生长研究

Study on Yield and Plant Height Growth of Different Hemp Varieties(Lines) in Tianshui Ecological Environment

摘要:

以从国内引进的14个大麻品种（系）为试材，在甘肃省天水市高寒阴湿地区种植，研究不同品种（系）在当地物候期、主要性状、产量等表现。试验结果表明：株高以六安大麻最高为361.67 cm；种子产量民勤大麻3最高，达到74.76 kg/667 m²，比对照增产71.49%，内蒙古大麻次之，为71.70 kg/667m²，比对照增产64.68%；昆明大麻的纤维产量达到72.63 kg/667 m²，比对照增产133.31%，干茎产量达到352.77 kg/667m²，比对照增产165.56%。昆明大麻、六安大麻、皖大麻的适应性较强，纤维产量高，表现出明显的优势，适宜在天水市推广种植，巴马火麻的纤维产量较高，为次适宜推广种植品种。出苗后各个品种（系）株高生长相差不大，此后不同品种（系）同期内株高生长曲线差异较大。

Abstract:

Using 14 hemp varieties（lines） imported from China as test materials, they were planted in the alpine and humid area of Tianshui City, Gansu Province, to study the performance of different varieties（lines） in the local phenological period, main characteristics, and yield. The test results showed that the highest plant height was Luan hemp, which was 361.67 cm; The seed yield of Minqin hemp 3 was the highest, reaching 74.76 kg/667m², an increase of 71.49% compared with the control, followed by Inner Mongolia hemp, 71.70 kg/667m², an increase of 64.68% compared with the control; Kunming hemp fiber output reached 72.63 kg/667m², an increase of 133.31%compared with the control, dry stem output reached 352.77 kg/667m², An increase of 165.56% over the control. Kunming hemp, Lu'an hemp and Anhui hemp have strong adaptability, high fiber yield, and show obvious advantages,which are suitable for planting in Tianshui City, Bama hemp has higher fiber yield, which is the second most suitable planting variety. After emergence, the plant height growth of each variety（line） is not much different, and thereafter the plant height growth curve of different varieties（lines） varies greatly during the same period.
