摘要
"尤纱-14"是工业用大麻新品种,具有较好的农艺性状。但大麻苗期的田间杂草是影响大麻生长的主要因素。因此,用8种除草剂分三个生长期进行防除大麻田杂草的筛选试验,考察其对杂草的防除效果以及药害情况。试验结果表明:在同一环境条件下,不同生育时期,在大麻田间试验的8种除草剂中,苗前撒药效果最好,茎叶除草剂的效果不明显。金都尔的综合效果最好,其除草效果明显,并且对大麻安全,可以作为大麻除草剂推广使用。
＂US-14＂ is the new hemp variety for industrial use, it has good agronomic characters. However, field weed is a major factor affecting the growth of hemp in the seedling stage. A screening test was carried out in three terms with 8 herbicides to control weeds in hemp field and weed control effect and the phytotoxieity were studied. The test results showed that： under the same environmental conditions and in different growth stages, pre-emergence application effect was the best, efficiency of post-emergence herbicides was not obvious. Among 8 herbicides, Seoul Cream was the most effective in controlling weeds in hemp field, besides, it was safe and harmless and lasted longer.
