摘要
采用大田小区试验研究了黔北烤烟不同起垄及地膜覆盖方式的保水效果。结果表明,对于单行垄和双行平垄,全生育期盖膜相对于团棵期揭膜不利于雨水向土壤补充,揭膜与否对烤烟的农艺性状和经济性状影响不明显;对于双行凹垄,全生育期盖膜相对团棵期揭膜有利于水分向垄体内补充,有利于保水,对烤烟的农艺性状和经济性状有明显的促进作用。在团棵期揭膜的条件下,双行平垄保水效果和经济性状表现最好;在全生育期盖膜条件下,双行凹垄的集雨和保水效果最好,其农艺性状和经济性状均明显好于其他起垄方式。
Effects of different ridging and mulching pattern on soil moisture retention for flue-cured tobacco in north Guizhou was studied using field plot experiment.The results showed that,on the condition of single-row ridge and double-row ridge,mulching cultivation during the whole growing period could reduce water supply to the soil.There was no obvious differences on the growth and economic properties between covering film or not.Mulching cultivation during the whole growing period could not only improve water supply in the soil and help the soil to hold water,but also could improve the growth and e-conomic properties on the condition of double-row concave ridge.The double-row concave ridge had the best effect on holding water and the economic properties on the condition of uncovering film.Whereas the double-row concave ridge had the best effect on soil moisture retention and rainfall conservation,and improving the growth and economic properties of flue-cured tobacco leaves obviously as well on the condition of mulching cultivation during the whole growing period.
