    摘要:

    液态地膜和植生带是2类新兴的土壤改良和覆盖保水材料。通过盆栽和田间实验,比较了液态地膜和植生带及其配合使用对土壤水分和温度及玉米成苗的效应。结果证明纤维植生带和棉质植生带及其与液态地膜配合应用保持水土效果虽好,但极大影响玉米出苗;液态地膜保水增温效果明显,玉米出苗率最高,是值得研究和推广的新型保墒抗旱成苗措施。

    Abstract:

    Liquid film is a new kind of soil conditioner and compartmentalisation is a new method for turf building.Experimentation shows the effect on soil water,soil temperature and seedling growth in an arid environment of liquid film,compartmentalisation and their combination.The results indicate that fiber compartments and cotton compartments used together with liquid film can improve soil water conservation,but reduce considerably maize seedling growth rates.Liquid film alone showed the best results,improving soil water conservation and soil temperature and enabling a higher seedling growth rate in an arid environment than the other methods.Liquid film warrants further study and application as a new measure to preserve soil moisture and enhance seedling growth in arid environments.
