摘要： 研究表明，和常规种植相比，侧膜种植苜蓿出苗提前3d，幼苗高增加57%，茎粗增加21.7%，根长增加2~4cm，播种第2年，株高增加30.77%，单株分枝数增加12%，茎叶比较常规种植低，播种当年增产21.14%，第2年增产83.64%，2年累计净收益2916.88元/hm2 。

Abstract: Compared with the common drilling, alfalfa seedling in planting with plastic film emerged in advance of tree days, seedling stem height increased 57%,seedling stem wide increased 21.7% and root Length increased 2~4cm. Compared with CK, alfalfa stem height increased 30.77%. Branch increased 12%, Ratio of stem to leave was lower than CK, Yield of alfalfa increased 21.14% in first year of planting with Plastic film and increased 83.64% in second year. Net income in two years comed to 2916.88 Yuan/hm2.
