Influence of the adverse condition of shading-nets on yield and quality of flue-cured tobacco

  • The influence of the adverse condition of shading-nets in flue-cured tobacco was studied.The res ults show that the field clim ate changes remarkably under the shading-net cover.The average daily temperature decreases by 3.2"C .The penetrating rate among plants reduces by 17.2% .The evaporations among rows and plants respectively drop 1.7mm and 1.0mm .The climate change makes flue-cured tobacco delay in bud emergence and blossoming,and decrease its growth of roots,stems and leaves.The yield decreases to 1126.5kg/hm2.The percentage of the superior and medium tobacco reduces by 36.1%.Therefore.a 1ong term of covering is not suitable for flue-cured planting.
