摘要
采用定期、定量浇水的方式研究了土壤水分对烤烟叶中钾含量的效应。结果表明 ,烤烟生育前期土壤水分过多或过少均不利于烟株的生长发育并导致烟叶中钾含量降低。依据不同年分的降雨情况采取间隔 4～
Study on the effect of soil water on potassium content of flue-cured tobacco leaf with regular and fixed quantity watering method.The results showed that more or less soil water in earlier growth period was all bad to growth and development of flue-cured to bacco which led to lower potassium content in leaf blade.According to the rain of different year,it could significantly increase potassium content of flue-cured tobacco leaf by watering once every 4～8 days or applying preservative water preparation.$$$$
