烤烟集约化育苗生产适应性研究

[目的]探讨烤烟集约化育苗所育烟苗的生产适应性。[方法]通过对集约化立体育苗所育烟苗素质统计分析、3种不同栽培技术的不同栽培试验、营养生长结束后田间农艺性状统计分析对烤烟集约化立体育苗的生产适应性进行探索研究。[结果]烤烟集约化立体育苗较常规漂浮育苗所育烟苗弱。膜下井窖式移栽技术是烤烟集约化立体育苗所育烟苗的最佳移栽技术。采用膜下井窖式移栽技术,烤烟集约化立体育苗能够适应烤烟生产。小苗、弱苗适宜采用膜下井窖式移栽。[结论]该研究可为烤烟集约化立体育苗技术的推广应用提供必要的理论依据和技术支持。

Study on Production Adaptability of Flue-cured Tobacco Intensive Three-dimensional Seedling

The aim was to discuss the production adaptability of the tobacco seedlings cultivated by flue-cured tobacco intensive three-dimensional seedling. [Method]The tobacco seedlings cultivated by flue-cured tobacco intensive three-dimensional seedling were used to carry out the statistical analysis of tobacco seedling quality,different cultivation tests of three different cultivation technologies,and the statistical analysis of field agronomic traits after vegetative growth to explore their production adaptability. [Result]The quality of the seedlings cultivated by flue-cured tobacco intensive three-dimensional seedlings were weaker than that of the seedlings by tobacco floating seedling. The film mulching tobacco plantlet transplanting in well cellar（FMTPTIWC） was the best transplanting technology for the tobacco seedlings cultivated by flue-cured tobacco intensive three-dimensional seedling. The flue-cured tobacco intensive three-dimensional seedling was adapted to the tobacco production by FMTPTIWC. The FMTPTIWC was the best transplanting technology for weaker or minor seedlings of tobacco. [Conclusion] The study provides a necessary theoretical basis and technical support for promotion and use of flue-cured tobacco intensive three-dimensional seedling technology.
