摘要
本试验对雪茄茄衣烟的农艺性状、干物质积累和矿质营养吸收规律进行了研究,结果表明：雪茄茄衣烟株旺长期所需的最适温度为20.0~32.4℃、湿度为55.3%~83.7%;干物质积累最快的时期是移栽后35~65 d;根部矿质元素积累最多的时期在移栽后35 d左右,而茎和叶的矿质元素含量则在后期较高。
The agronomic characters,dry matter and mineral nutrient accumulation were studied in cigar wrapper tobacco. The results showed that the optimum temperature and humidity for tobacco plants in rapid growth period were 20. 0 ~ 32. 4℃ and 55. 3% ~ 83. 7% respectively. The rapid accumulation period of dry matter appeared in 35 ~ 65 days after transplantation. The mineral nutrients accumulated the most in root in the period of about 35 days after transplantation,while those accumulated more in aboveground part in the late growth period.
