不同移栽方式对烤烟田间长势的影响

Effects of Different Transplanting Methods on Growth of Flue-cured Tobacco in Field

为探索临沂烟区烤烟最佳移栽方式,以中烟100烤烟品种为试验材料,采取随机区组试验方法,研究了井窖式膜下移栽、小苗膜下烟移栽和普通春烟移栽等3种不同移栽方式对烤烟田间长势的影响。结果表明,井窖式膜下移栽、小苗膜下烟移栽时间较普通春烟移栽早13～16 d,提高烟苗成活率,延长烤烟大田生育期4～8 d;井窖式膜下移栽、小苗膜下移栽各农艺性状优于普通春烟移栽,且抗病性较强,各病害发病率相对较低。

In order to explore the best transplanting method for tobacco in Linyi area,the effects of three methods of different transplanting such as down-film transplanting of the ＇Well-cellar＇ ,down-film transplanting of the small seeding and the ordinary spring tobacco transplanting on the growth condition in field were studied through randomized block tests of Zhongyan 100.The results showed that compared with ordinary spring tobacco transplanting,down-film transplanting of the＇Well-cellar＇ and down-film transplanting of the small seeding were earlier than 13-16 d, tobacco seedling survival rate was improved, prolong the growth period of flue-cured tobacco in the field was prolonged for 4-8 d;agronomic characters of that down- film transplanting of the ＇Well-cellar＇ and down-film transplanting of the small seeding were better than the ordinary spring tobacco transplanting, and had strong disease resistance, the disease incidence were relatively low.
