摘  要:
通过对豆薯各生长时期进行50%的遮光试验。试验结果表明,全生育期遮光,不能形成块根和种子产量;幼苗期遮光苗素质下降;开花结荚期遮光,不能形成荚果;鼓粒期遮光,种子减产75.98%。因此,无论是豆薯块根或是种子生产均应选择光照充裕的适宜地区种植,特别是在山区应尽量选择山阳地块种植。

摘  要:
Through the growth period of Pachyrrhizus erosus,50% shadow was stuied. The results show that shading the whole growth period,the root couldn't be formed and seed production decreased; seedling stage the quality of shading seedlings decreased; flowering and podding period shading,legumen couldn't be formed,75.98% of seed production decreased. Therefore,whether it is root or seed production of Pachyrrhizus erosus should choose an adequate level of illumination,suitable cultivation areas,especially in the mountains.
