为防止烤烟大田后期早衰和提高上部烟叶质量,在湖南省浏阳市研究了单垄不覆膜、凹形双垄不覆膜、凹形双垄侧覆膜对烤烟大田后期根层水热环境、烤烟根系、上部烟叶生长发育、烟叶经济性状和质量的影响。结果表明:在烤烟大田后期,凹形双垄侧覆膜较单垄栽培的土壤水分高1.31%~6.38%,温度低3.30~4.94 ℃;根的总长度、平均直径、根总体积、根系活力分别提高37.62%、34.92%、69.18%、10.85%;上部烟叶面积、SPAD值、上等烟比例、产值、物理特性指数和化学成分可用性指数分别提高20.61%、10.04%、8.07%、7.20%、5.90%和25.39%。凹形双垄侧覆膜较不覆膜栽培的土壤水分高1.95% ~ 2.65%,温度低1.41 ~ 3.25℃...

In order to avoid premature senility of tobacco during late period of field-planting and to improve the quality of tobacco upper leaves, the effects of different planting patterns of tobacco (single ridge, concave ridge double-row, concave ridge double-row and side mulching) on the moisture and temperature of plough soil, the root of tobacco, the growth, output and quality of tobacco upper leaves were studied in Liuyang City, Hunan Province. The results showed that, compared with control (single ridge cultivation), concave ridge double-row and ...
