摘要
以“格兰蒂”为试材，研究了小拱棚、小拱棚加地膜覆盖（双膜覆盖）和地膜覆盖的增温效应及对绿芦笋早春生长和产量的影响。结果表明，3种覆盖方式均显著提高地温，促进芦笋提前萌芽出笋，其中以小拱棚增加地温和促进提早萌芽的效应最大。小拱棚和双膜覆盖可提高气温4℃～14℃，使芦笋生长速度加快，采笋期提前10d左右，早期产量是对照的2倍以上。小拱棚覆盖对绿芦笋的一级笋率无显著影响，而双膜覆盖和地膜覆盖的弯笋率比对照增加，一级笋率比对照降低。
Effects of different mulch methods on siol and air temperature, growth ang early yield of green asparagus were studied. The results indicated that planstic tunnel, planstic film mulch in planstic tunnel and only planstic film mulch all increased the soil temperature and preceded the sprouting and harvest time. And the planstic tunnel showed the greatest effect. Planstic tunnel and planstie film mulch in planstic tunnel increased air temperature 4℃～ 14℃ and hastened the growth of asparagus sprout. Harvest time was about 10 days earlier and early yield was more than 2 times both in planstic tunnel and planstic film mulch in planstic tunnel than the control. The percent of the first grade asparagus sprout in planstie tunnel had no difference with control. But it was lower in the treatment of planstic film mulch in planstic tunnel. The bending sprouts increased in treatment of planstic film mulch in planstic tunnel and only planstic film mulch.
