摘要
以单雌性工业大麻云麻雌 1 号作为对象,研究不同雌雄配比(雄株比例为 10%、20%和30%)种植模式下种植密度(5210、10 420、15 630 株/hm2)对麻籽和麻糠产量的影响,进而探讨单雌性工业大麻用于籽糠兼用的生产模式.结果表明,在同一雌雄比例下,种植密度越大,麻籽、麻糠、麻秆及大麻二酚(CBD)理论产量越高;在最大种植密度15 630 株/hm2下,20%雄株率下的麻籽、麻糠、麻秆及CBD理论产量均高于 10%和 30%雄株率的产量,其麻籽产量为5738.02 kg/hm2,麻糠产量为6087.14 kg/hm2,麻秆产量为 9396.35 kg/hm2,CBD理论产量 127.58 kg/hm2.在单雌性工业大麻云麻雌1 号籽糠生产实践中,建议配置花期一致的 20%左右雄株,保证授粉充足,实现麻籽和麻糠丰产.
Abstract
Taking an all-female industrial hemp variety Yunmaci 1 as the research object,we ex-plored the effects of the different sex ratios(10%,20% and 30%male plants)and different planting densities(5210 plants/hm2,10 420 plants/hm2 and 15 630 plants/hm2)on the yields of seeds and chaff,which was benefit of improving the production modes for dual-purpose hemp.The results showed that under the same sex ratio,the higher the planting density is,the higher yields of hemp seeds,chaff,stalks and CBD could be obtained.Under the maximum planting density of 15 630 plants/hm2,the theo-retical yield of seeds,chaff,stalks and CBD at a male plants rate of 20%were higher than that of 10%or 30%,and gained at 5738.02 kg/hm2,6087.14 kg/hm2,9396.35 kg/hm2 and 127.58 kg/hm2,re-spectively.For both seed and chaff production test of Yunmaci 1,allocating 20%male plants in the flow-ering period in all female hemp field was recommended to ensure adequate pollination and achieve high yield of hemp seeds and chaff.
