    摘要:

    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。

    Abstract:

    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 keep warm when the day is cloudy or rainy; Temperature was high in the hole of cellar-wall at sunny day, but deeper in the hole, lower the temperature was. The tiny weather in the hole which formed by well-cellar transplanting method and use small tobacco seeding is helpful to tobacco seeding growth,that grew faster than up-film transplanting method, showed at stem girth, biggest leaf length and leaf width, but the seeding used by up-film transplanting method grown into fast rate at ten days later; small seeding used by well-cellar transplanting is good than the big; So, choice well-cellar transplanting method, not only shift to an earlier date but also decrease the harmful influence of outdoor temperature changing to tobacco seeding, which is good for tobacco biological substance producing on earlier stage, and adopt the flue-cured tobacco producing at Yingjiang area.
