膜下移栽对烤烟生长发育及品质的影响

Effects of Different Seeding Transport Under Plastic Mulching to Flue-Cured Tobacco in Growth and Quality

采用田间试验研究了膜下移栽、常规盖膜移栽和常规移栽不盖膜3种不同的覆膜移栽方式对烤烟生长发育以及品质的影响。结果表明:膜下移栽措施提高了烟株团棵期整体度,明显改善了烤烟农艺性状指标,提高了烤烟干物质量的积累,到生长后期膜下移栽干物质累积量同比常规移栽不盖膜多出124.68g。膜下移栽处理的烟叶中的氮在移栽后60天内持续上升,对烟叶生长发育有很好的作用。膜下移栽处理明显提高了烤烟产量、产值和中上等烟比例,其中上等烟比例比膜上移栽和不覆膜移栽高7～8个百分点,且其总体化学成分含量适宜,协调性好。

A field experiment was used to discuss the impacts of growth and quality of flue-tobacco under seeding transport under plastic mulching, conventional mulching transplant and transplant without mulching. The results showed that under plastic mulching transplanting improve the overall degree of tobacco plants in rosette stage and agronomic traits sig- nificantly and the accumulation of cured tobacco. The accumulation of cured tobacco was more 124.68g than conventional transplanting without mulching in late growth stage. The sustained increase in nitrogen content in leaves was good to fluecured tobacco in 60 days after transplant. And seeding transport under plastic mulching significantly improved the proportion of output production and middle and upper tobacco, and the upper tobacco was improved 7 to 8 percent, and the general chemical composition is in good appropriate and coordination.
