试验研究了吉林省烤烟小苗膜下移栽技术,以探明其对烟苗生长的微环境和肥料利用率及早生快发的影响。通过对不同的移栽苗龄及大田移栽期所培育烤烟的农艺性状、肥料利用率、烤后化学成分及经济性状的分析比较,结果表明:小苗膜下移栽使苗穴内能够保持相对稳定的温度,为幼苗提供适宜的生长环境,优于常规移栽方法。烟株的各项农艺性状表现较好,对肥料的利用率显著高于对照,烤后经济性状提高,化学成分协调性改善。小苗膜下移栽技术最佳移栽苗龄为6叶龄,最佳移栽时期为4月26日至5月1日。
The experiment was conducted to study the film transplanting technology of flue-cured tobacco seedlings in Jilin Province in order to find out its influence on the microenvironment and the utilization rate of fertilizer and the rapid growth of tobacco seedlings. Through the analysis of agronomic traits, fertilizer utilization rate, chemical composition after roasting and economic traits of transplanted seedlings and transplanting flue-cured tobacco at different transplanting stages, the results showed that seedling transplanting could make the seedlings maintain relative stability Of the temperature, seedlings provide suitable growth environment, better than the conventional method of transplanting. The agronomic traits of tobacco plants performed better, the utilization rate of fertilizer was significantly higher than that of the control, the economic traits after baking increased, and the chemical composition coordination improved. Under transplanted seedlings under the optimal transplanting technology seedling age of 6 leaf age, the best transplanting period from April 26 to May 1.
