不同移栽方式和地膜类型对攀枝花烤烟小苗膜下生长及产质量的影响

Effects of Transplanting Method and Plastic Film Type on Growth,Yield and Quality of Flue-cured Tobacco Seedling Transplanting under Film in Panzhihua

为探明攀枝花烟区适宜的烤烟小苗移栽方式及地膜覆盖类型,采用大田随机区组设计,开展了不同移栽方式和地膜类型对烤烟小苗膜下生长及产质量影响的试验。结果表明:与其他处理相比,挖窝移栽并覆盖黑色地膜,破孔前后穴内温度适宜,烟苗成活率达100%;各生育期烟株农艺性状表现较好,显著增加了有效叶片数和最大叶面积;同时显著提高了烤后烟叶产量、产值、均价以及上中等烟比例,各项化学成分含量适宜,比例协调,最接近优质烟叶适宜含量范围。因此,在攀枝花烟区实施挖窝覆盖黑色地膜的烤烟小苗膜下移栽技术,成活率高,烟株大田生长良好,烟叶产质量提高。

To study the best flue-cured tobacco transplanting method and the suitable plastic film type in Panzhihua tobacco region,Sichuan Province,a randomized block field experiment was carried out to estimate the effects of different transplanting method and plastic film type on the growth,yield and quality of tobacco seedling transplanting under film. The results indicated that,compared with the other treatments,‘Digging-fossa＇with black plastic film transplanting could provide a suitable temperature environment pre and post film breaking,reached the survival rate 100%,improved the agronomic properties,significantly increased the effective leaves,the biggest leaf area,the tobacco yield,output,average price and the proportion of superiorand middle tobacco,meanwhile,the content and the ratio of chemical compositions of tobacco leaf were suitable and most close to the appropriate content of high quality tobacco. Thus,application of ‘Digging-fossa＇with black plastic film transplanting the flue-cured seedling in Panzhihua had high survival rate and good effects on tobacco agronomic properties,yield and quality.
