摘要 连续两年稻草还田试验结果表明，其稻草翻压、覆盖对改良土壤和提高烟叶产量效果明显。稻草还田的土壤速效氮磷钾养分释放量高于对照。总的趋势以稻草翻压＞稻草覆盖＞CK。稻草翻压比对照平均增产12.0%，稻草覆盖比对照平均增产6.7%。且烟叶内在成分基本趋向合理，上、中等烟叶比例达90%以上。

Abstract For two consecutive years of straw to field test results show that the pressure over its rice straw to cover the soil and increase tobacco production evident result. Straw also available-the soil nutrients nitrogen, phosphorus and potassium than emissions control. The general trend over the straw pressure> straw covered> CK. Straw pressure than the control over the average yield 12.0 percent, straw coverage than the control average yield of 6.7%. And the basic components of tobacco inherent tendency reasonable, upper-level, middle level of tobacco ratio of 90 percent or more.
