| 摘 要： | 调查了不同品种类型、蒜种类型和栽培措施的大蒜植株的二次生长率.结果表明,早熟品种二次生长发生率最高,中早熟品种其次,中熟品种最低.早熟品种二次生长主要以外层型(Gso)为主,中早熟和中熟品种则主要以内层型(Gsi)为主;蒜种类型与二次生长的发生没有直接关系;增施微肥、农家肥、NAA 50 mg/L BA 5mg/g与对照(常规施肥)间二次生长率差异不显著,但增施微肥、农家肥有降低大蒜二次生长发生的趋势;免耕稻草覆盖栽培的大蒜二次生长发生率和死叶率比翻耕土壤覆盖栽培的明显高,死叶率高伴随二次生长率亦高.

| Abstract: | Effects of varieties, seed-bulbs and cultivated methods on the secondary growth rate in garlic were investigated. The results showed that in the secondary growth rate, early mature variety was highest in the secondary growth in out leaves, mid-early mature variety was lower, and middle mature variety was lowest. The secondary growth occurs mainly in innerleaves in mid-early varieties and middle mature. There is no marked difference in seed-bulbs between normal and secondary growth. Microelement fertilizer, farmyard manure and growth regulator (NAA BA) couldn't inhibit the secondary growth significantly. But there was a decreasing trend in microelement fertilizer and farmyard manure treating plants. The rate of secondary growth and rate of died leave were higher in the plants growing under zero-tillage, covering with straw than that growing under ploughed and covering with soil. The more died leaves was, the heavier secondary growth occurred in garlic plants. |
