在江苏靖江地区观察靖江香沙芋的生长发育动态,为制定靖江香沙芋的高产栽培技术体系奠定基础。结果表明,靖江香沙芋分株萌芽期约为出苗后46 d(7~8叶);母芋膨大始期约在出苗后125 d(12叶),此时普遍形成子芋;出苗后约141 d(15叶)孙芋开始大量发生;出苗后约150 d(15~16叶)停止发生,之后直到成熟收获期,子孙芋鲜重快速增长9月初是靖江香沙芋由以营养体生长为主向以下块茎生长为主的转换期。
To observe the growth and development of Xiangjiang incense in Jingjiang, Jiangsu, and to lay the foundation for the formulation of high-yielding cultivation technology system of Xiangjiang. The results showed that the stage of seedling emergence of Jingjiang Yam was about 46 days after emergence (7-8 leaves); the period of initial expansion of Yam was about 125 days after emergence (12 leaves) (15 leaves) began to occur a large number of sun-taro; about 150 d after emergence (15 to 16 leaves) to stop, until after the mature harvest, rapid growth of fresh weight of taro early September is Jingjiang Xiang taro vegetative growth of The main to the following tubers growth-based conversion period.
