为探索适应贵州省印江烟区生态条件的烟苗移栽方法,比较了地膜小苗井窖式移栽、地膜大苗井窖式移栽和常规膜上移栽的垄内土壤温度、井窖孔穴内温度和烟苗农艺性状表现。结果表明:井窖式移栽较常规移栽更能维持垄内土壤温度的稳定;井窖式移栽的孔穴内温度在阴雨天保持稳定,有利于抵抗外界低温对烟苗的影响,晴天时孔穴口温度虽较高,但随着孔穴深度的增加,温度逐渐降低;井窖式移栽使井窖内形成独特的"微环境",有利于烟苗移栽后即进入快速生长,其中以小苗的表现优于大苗。井窖式移栽烟苗的茎围、最大叶长和最大叶宽均明显优于常规移栽,而常规移栽烟苗在栽后10 d才开始表现出较快的生长态势。

In order to find a best transplanting method to adopt the climate of Yinjiang county, Guizhou province, three transplanting methods （well-cellar transplanting method use small seeding, well-cellar transplanting method use big seeding and up-film transplanting method） been studied, compared, the temperature of_ridge soil and hole of well-cellar and agronomic characters. The result shows, two well-cellar transplanting methods could maintain the temperature of ridge soil stability than up-film transplanting method; The hole of well-cellar could ...
