【摘要】 调查研究结果表明,甜叶菊种子的冠毛占到种子总重量的45.92%。甜叶菊在宁夏同心县贫瘠土地的大田移栽后经过早期65d的慢速生长阶段和后期的快速生长阶段。单产达到4635kg/hm2,由此说明在宁夏的肥沃农田种植,甜叶菊可以高产。宁夏种植甜叶菊可以改变当地农业产业结构,并为民族地区喜欢饮食甜味的群众提供新的甜味剂。更多还原

【Abstract】 Investigation of the characteristics of Stevia rebaudiana(Bertoni) Hemsl seeds indicated that seed pappus accounted for 45.92% of the total weight of the seed. Field growth experiment by transplanting Stevia onto barren land in Ningxia Tongxin area showed that Stevia plants grow fast at seedling stage, grow rapidly at the later stages before slowdown at early 65 days stage and its yield reaches 4635 kg/ha. It is possible that Stevia can grow to high yield if planted on fertile farmland in Ningxia. Stevia cultivation in Ningxia would be a valuable addition to the local agricultural industry, and provide a delicious diet sweetener for the region.更多还原
