摘　　要：在山旱地条件下,对兰州百合进行了秸秆+地膜覆盖、地膜覆盖、秸秆覆盖和不覆盖4种栽培方式处理,研究了不同覆盖方式对土壤温湿度及兰州百合鳞茎产量的影响。结果表明:在百合生长前期,土壤平均温度和含水量均是秸秆+地膜覆盖栽培>地膜覆盖栽培>秸秆覆盖栽培>不覆盖栽培。并且秸秆+地膜覆盖栽培百合茎粗,株高,叶片数多,出苗期较传统不覆盖栽培提前10d,鳞茎产量提高12.15%。Under the dry land condition,four cultivation methods of the straw＋plastic film mulch,the plastic film mulch, the straw mulch and non membrane cover were used to study the effect of different cover means on soil temperature and humidity and the production of bulb of Lanzhou lily. The results showed that the soil average temperature and soil water content were straw and plastic mulching cultivationS〉plastic film mulch〉the straw muich〉non membrane cover in the early stage of lily growth. And straw and plastic mulching cultivation stem diameter, plant height ,leaf number of lily was more,seeding stage than the traditional non membrane cover less than 10 d,bulb production increased by 12. 15%.
