移栽期及抗寒剂对烤烟生长发育及产量的影响
Effects of Different Transplanting Period and Cold-resistant Agent on Tobacco Growth and Yield
摘要
Abstract
In order to evade effectively adverse weather conditions in the actual production of flue-cured tobacco, such as low temperature stress in the early phase and heat forced maturity in the later, the field experiment was conducted to study the effects of different transplanting period and cold-resistant agent on tobacco growth and yield. The result showed that the tobacco leaf number was much more, and the leaf area was moderate when transplanting seedling under plastic film mulching 5 days in advance, while the leaf number was slightly less, the leaf area was the largest when transplanting under the plastic film mulching 10 days in advance.Spraying cold-resistant agent alone could cause slender leaves. It was pro-pitious to enhance the proportion of better-than -average tobacco and the yield when transplanting earlier.and spraying cold-resistant agent.关键词
