摘要
为探究多效唑处理对工业大麻花叶产量和大麻二酚(CBD)含量的影响,以云麻8号为试验材料,设5个多效唑浓度(C_(0):0 mg/L,C_(1):100 mg/L,C_(2):200 mg/L,C_(3):300 mg/L,C_(4):400 mg/L)和2个喷施时期(T_(1):旺长初期,T_(2):旺长中后期)处理,通过农艺和产量性状的测定分析,筛选对提高工业大麻花叶产量和CBD含量最有效的多效唑喷施浓度和时期。结果表明,在农艺性状方面,T_(1)时期喷施200 mg/L多效唑对降低株高、增加茎粗和分枝数的作用最为显著。在产量方面,T_(1)和T_(2)时期,随多效唑喷施浓度的增加,花叶和茎秆产量呈先上升后下降的趋势,其中,C_(2)T_(1)处理下,工业大麻的花叶产量最高,为3642.22 kg/hm^(2)。随多效唑喷施浓度的升高,2个时期CBD含量均呈先上升后下降的趋势,其中,T_(1)时期喷施200 mg/L多效唑,CBD含量最高,为3.53%。综上,C_(2)T_(1)(200 mg/L+旺长初期)为最佳处理组合。
In order to explore the effects of polyazole spraying treatment on the yield and cannabidiol(CBD)content of industrial hemp inflorescence and leaves,the Yunma 8 was taken as the experimental material,five polyazole concentrations(C_(0):0 mg/L,C_(1):100 mg/L,C_(2):200 mg/L,C_(3):300 mg/L,and C_(4):400 mg/L)and two treatment periods(T_(1):the early stage of rapid growth,T_(2):the middle and late stages of rapid growth)were set in this study.Through the measurement and analysis of agronomic and yield traits,the most effective polyazole treatment concentration and period for increasing the yield and CBD content of industrial hemp inflorescence and leaves were screened.The results showed that 200 mg/L polyazole had the most significant effects on reducing the plant height of Yunma 8 and increasing its stem thickness and the number of branches at T1 period.From the results of the yield traits,with the increase of polyazole concentration,the yield of inflorescence,leaves and stems of industrial hemp all showed a trend of first increasing and then decreasing at both the T_(1) and T_(2) periods.Among them,the yield of industrial hemp reached the highest value under C_(2)T_(1) treatment,with a yield of 3642.22 kg/ha for inflorescence and leaves.With the increase of polyazole concentration,CBD content of industrial hemp showed a trend of first increasing and then decreasing at the both periods.Among them,the highest CBD content was 3.53% by 200 mg/L polyazole treatment at T_(1) period.Based on the above results,it can be concluded that C2T1(200 mg/L and the early stage of rapid growth)treatment was the optimal treatment combination in this study.
