摘要: 为探讨不同光周期与肥料配比对设施内工业大麻生长及CBD产量的影响,以一年生花叶用工业大麻品系为材料,通过设置3个光周期处理与3因素(氮、磷、钾)、4水平的肥料效应试验,筛选出最佳补光方案与施肥配比。结果表明,在18 h/d光周期下的工业大麻具有最高的农艺指标、叶产量与CBD产量,同时在该处理下工业大麻叶片的净光合速率最高;在N1P2K2处理(P2O5:5.18 g/盆、K2O:5.18 g/盆、N:7.00 g/盆)下叶产量与CBD产量最高,并且达到最高产量效应值、肥料农学效率与肥料贡献率,其光合参数与叶绿素相对含量也处于最高水平。研究得出18 h/d的光周期与N1P2K2的施肥水平最利于工业大麻生物产量与CBD产量的提高,这对花叶用工业大麻设施内高效栽培有一定的参考价值。

Abstract: In order to explore the effects of different photoperiods and fertilization ratios on the industrial hemp growth and CBD yield in the protected cultivation, one-year-old industrial hemp strains were used as the material, and three photoperiod treatments and 3-factor(nitrogen, phosphorus, potassium), 4-level fertilization experiments to were set up screen out the best light supplement scheme and the best fertilization ratio. The results showed that industrial hemp had the highest agronomic index, leaf yield and CBD yield under the 18 h/d photoperiod, and the leaf photosynthetic rate was also the highest under this treatment; the highest Leaf yield, CBD yield, yield effect value, fertilizer agronomic efficiency and fertilizer contribution rate were achieved under N1P2K2 (P2O5:5.18 g/pot, K2O:5.18 g/pot, N:7.00 g/pot) treatment, and the photosynthetic parameters and relative chlorophyll content were also at the highest level. This study concluded that the photoperiod of 18 h/d and the fertilization level of N1P2K2 were the most conducive to the increase of industrial hemp production and CBD yield, which had certain reference value for the efficient cultivation of industrial hemp in the protected cultivation.
