| 摘 要： | 盘县烟区旱土种植烤烟,烟苗移栽期常遇干旱,为提高烟草成活率,在移栽期研究了不同浇水量及不同移栽期对烤烟生长发育的影响,以确定盘县烤烟最佳移栽期和烤烟移栽最低需水量。结果表明:在土壤水分为11.42%的条件下进行盖膜栽烟,且短时期内未降雨的情况下,浇水量1.0 kg/株能保证移栽成活率达97%;5月15日后移栽的烤烟比4月25日前移栽的烤烟现蕾时间延迟6.5 d,农艺性状表现也相对占优势。

| Abstract: | The tobacco seedlings,which planted in arid soil of Pan County,always had drought problem in transplanting time.In order to improve the survival rate of tobacco,the influences of different irrigation volumes and the different tobacco transplanting time on growth of tobacco were studied to determine the optimum transplanting time and the lowest water demand of tobacco in Pan County.The results indicated that planting tobacco to the soil with moisture of 11.42% and covered with plastic film,and no raining in a short period,the irrigation volume of 1.0 kg/plant can guarantee the survival rate of transplanted tobacco reached 97%.Through determining the agronomic characters of tobacco transplanted at different time,the results indicated that in comparison with the tobacco transplanted before April 25,the tobacco transplanted after May 15 delayed 6.5 d in flower bud emerging time,and had better performances in agronomic characters. |
