雌雄配比和种植密度对单雌性工业大麻籽糠产量的影响
Effect of Planting Densities on Seeds and Chaff Yields of All-female Industrial Hemp under Different Sex Ratio
摘要
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.关键词
