收获时期对工业大麻干物质产量及主要大麻素含量的影响
Effects of Harvesting Periods on Dry Matter Yield and Main Cannabinoids Content of Industrial Hemp
摘要
Abstract
In order to explore the suitable harvest period of industrial hemp and improve yield and quality,the effects of'Hanma 7'and'Saima 1'were used as experimental materials to analyze the impact of different harvest periods on the yield,yield traits and CBD(cannabidiol),CBG(cannabigerol)and THC(tetrahydrocannabinol)content of industrial hemp.The results showed that 90-111d after transplanting,the flower and leaf yields,plant height,stem diameter,first branch height,number of branches,dry weight of flower and leaf per plant and dry weight of stem per plant showed a significant increase trend with the extension of harvest time,and the yield and related traits of'Hanma 7'performed better than'Saima 1'.The total CBD content,THC content and CBG content of the two varieties increased with the harvest time,and the total CBD content,THC content and CBG content of'Hanma 7'were slightly higher than that of'Saima 1'.Correlation analysis showed that the flower and leaf yields and yield traits,main cannabinoid content of the two varieties were positively correlated with harvest time.The study has shown that appropriate delayed harvest period can effectively increase the yield and main cannabinoid content of industrial hemp.关键词
