摘要
选用3个不同基因型的甘薯品种,采用正交试验设计,研究了百苗重和施肥量对甘薯块根的形成,特别是甘薯块根结薯个数的影响。结果表明,品种、百苗重及施肥量对甘薯根系发育有显著影响,南薯88在百苗重为4.0kg和不施肥条件下其根系重量和块根数量显著优于其他水平,同时南薯88根系数量最高。
The aim of this study was to study effects of 100-seedling weight and fertilizer application at earthnut stage on the number of root tuber in sweet potato.Three different genotypes of sweet potato varieties were tested by orthogonal design.The results showed that varieties,100-seedling weight and fertilizer application had significant effects on root development of sweet potato.For Nanshu 88,the treatment of 4.0kg of 100-seedling weight and no fertilizer ranked the best in root weight and the number of storage root.The number of roots of Nanshu88 were the highest.
