摘　　要：在烟田内进行了秸杆覆盖、秸杆覆盖 -抗旱剂组合的试验 ,以覆膜、常规栽培为对照。结果表明 ,秸杆覆盖、抗旱剂、秸秆覆盖 -抗旱剂具有明显保持土壤水分的作用 ,保持土壤水分的效果随秸杆覆盖、秸杆覆盖 -抗旱剂量的增加而增加 ;秸杆覆盖、抗旱剂、秸杆覆盖 -抗旱剂可明显改善烟株农艺性状 ,提高烟草产量和产值。兼顾烟草的产量和质量 ,秸杆覆盖 6 0 0 0kg/hm2 ,并喷洒抗旱剂 4 2 0g/hm2最理想。Straw overcast and FA is carried through in the tobacco's field. The CK is overcastting film and routine growth. The results show that straw overcast and FA can keep the soil's moisture. The effect increases with addition of straw overcast and FA. Straw overcast and FA can ameliorate agronomy character of tobacco and increase yield and production value of tobacco.As far as yield and quality of tobacco, is concomed the best one of all treatments is straw overcast of six thousand kilogram per hectare and FA of four hundred and twenty gram per hectare.
