摘　　要：在季节性干旱十分严重的鄂西南烟区,通过采取不同起垄和覆盖措施对保水效果进行研究。结果表明,双行垄栽培烟叶旺长期和成熟期的集水和保水均具有明显效果,同时对土壤的通气和蒸发影响较大,容易造成一定程度的土壤墒情偏大;单垄全生育期覆膜栽培集水和保水能力都受到了较大的限制;揭膜培土并进行秸秆覆盖可以增加垄体的持水容量和保水能力。Effects of moisture retention by adapting different ridge and different covering pattern in flue-cured tobacco was studied in the Westsouthern of Hubei Province where seasonal drought is terribly strict. The results showed that the effect of moisture accumulation and moisture retention in flourishing stage and mature stage of tobacco leaves by double-row ridge cultivattion pattern was significant. Simultaneously double-row ridge cultivation pattern had biggish influence in soil aeration and evaporition and apted to engender the soil moisture in certain degree. There was an obvious limitation in moisture accumulation and moisture retention by single-row ridge and tectorial cultivation during whole growing period. The capacity of moisture retention and moisture conservation had increased by uncovering film and crop straw covering.
