摘　　要：1992年3～6月在河北农大标本园进行了芦笋地膜覆盖栽培效应的试验。结果表明,地膜覆盖具有明显的增温保湿效应;能使芦笋产量提高31%;采收高峰前移9～10d;品质也明显提高,而芦笋的营养成分没有降低。地膜覆盖的打洞采收和揭盖采收之间差别不大。The research of effect of asparagus(Asparagus officinalis L.)covered with plastic film was done in the Specimen Garden of HebeiAgricultural University from March to June,1992.The results showedthat:Plastic film cover not only possessed obvious effects of raisingtemperature and preserving moisture,but also raised the yield per unitarea by 31%,with better quality,and without lost of nutrients.Additionally:with the plastic film cover,the harvest time peakappeared 9～10 days ahead of the usura time with little difference betweenhole-digging,harvest and uncovering collection in plastic film coveredfields.
