Sweet potato consumption is increasing in Canada, thus tuber imports are also increasing. There is significant and increasing interest in expanding commercial sweet potato production in Canada to address this growing consumer market. However, one main production limitation is the propagation of planting material (slips). Canadian climate conditions restrict the growing of slips during off season months while the same is not true of the United States (U.S). So Canadian sweet potato growers currently must rely on planting material from the U.S. Sweet potato slip production in greenhouses in Canada is an option but can be expensive and labor-intensive. Therefore, it is important to develop efficient and economical technical growing methodology for producing slips under suitable greenhouse settings that ensure optimum success. This study will contrast slip propagation methods, in a controlled environment growth room versus a modified passive solar greenhouse system to determine the most efficient way to commercially produce slips. The slips produced will then be field tested in field growing conditions for commercial production. The results will provide Canadian seed businesses/propagators an economically feasible process to grow sweet potato slips commercially in greenhouse systems with modified passive solar settings. Using this methodology, local slip producers can provide a higher quality product for growers, impacting crop success and improve yield resulting in further economic gain. Furthermore, local growers will have added control over the availability and quality of planting material. Increasing knowledge and expertise for growing sweet potato slips in Canada will lead to a possible expansion of sweet potato production acreage. Increasing the seeded sweet potato acres will help Canada meet growing consumer demand. As well, the further adoption of modified passive solar greenhouse systems promotes passive energy based technology that will reduce environmental impact and provide year-round production options.

加拿大的甘薯消费量正在增加，因此块茎进口也在增加。在加拿大，人们对扩大商业甘薯生产的兴趣越来越大，以满足这一不断增长的消费市场。然而，一个主要的生产限制是种植材料（插条）的繁殖。加拿大的气候条件限制了在淡季的几个月里的增长，而美国的情况并非如此。因此，加拿大甘薯种植者目前必须依赖来自美国的种植材料。在加拿大的温室中生产甘薯滑片是一种选择，但价格昂贵，劳动密集型。因此，重要的是要开发有效和经济的技术增长方法，生产滑下适当的温室设置，以确保最佳的成功。 本研究将对比滑移传播方法，在受控环境生长室与改进的被动式太阳能温室系统，以确定商业化生产滑移的最有效方式。然后将在商业生产的田间生长条件下对生产的卡瓦进行田间测试。 研究结果将为加拿大种子企业/繁殖者提供一个经济上可行的过程，在温室系统中使用改良的被动太阳能设置种植甘薯。使用这种方法，当地的滑生产商可以为种植者提供更高质量的产品，影响作物的成功并提高产量，从而进一步获得经济收益。此外，当地种植者将增加对种植材料的可用性和质量的控制。在加拿大增加种植甘薯片的知识和专业知识将导致甘薯生产面积的可能扩大。增加甘薯播种面积将有助于加拿大满足不断增长的消费需求。此外，进一步采用改良的被动式太阳能温室系统促进了基于被动能源的技术，这将减少对环境的影响，并提供全年生产选择。
