大麻是张家口地区主要经济作物之一。历年种子来源主要依靠从本省涞源和山西广灵等县调种,当地留种极不普遍。群众认为当地留种后代种性发生退化。但据我所1963年和1964年两年的调查、试验与过去的试验结果,在本地留种,自繁自用,后代种性没有退化现象。现将调查与试验结果整理如下,供留种参考。

Cannabis is one of the major cash crops in Zhangjiakou. The source of the seeds over the years rely mainly from the provincial sources such as Guangyuan and Shanxi Guangling seeding, the local species is extremely common. The people think that the local descendants have degenerated. However, according to the surveys and experiments conducted in both 1963 and 1964 in both my experiments and the past tests, there was no degradation of the descendants in the areas where they were planted in their own native place and used for their own purposes. Investigation and test results are now sorted as follows, for domestic species reference.
