摘　　要：为探究不同施肥处理对莴笋生长状况及产量的影响,在松潘县进行了施肥试验。结果显示,不同氮素水平显著影响莴笋的农艺性状和产量,150 kg/hm^(2)氮肥下莴笋的增产效果最为明显,其直径和单株质量分别增加至4.79 cm和0.96 kg,产量为99.46 kg/hm^(2),产值为179.50元/hm^(2),增产幅度高达41.32%,但当氮肥用量增至170 kg/hm^(2)时,莴笋的株高、直径和单株质量出现轻微下降。In order to investigate the effects of different fertilization treatments on growth and yield of Lactuca sativa,fertilization experiments were carried out in Songpan County.The results showed that different nitrogen levels had significant effects on the agro-nomic traits and yield of Lactuca sativa.The yield of Lactuca sativa increased to 4.79 cm and 0.96 kg per plant mass under 150 kg/hm^(2) nitrogen fertilizer,the yield was 99.46 kg/hm^(2),and the output value was 179.50 yuan/hm^(2).The yield increase was as high as 41.32%,but the plant height,diameter and individual plant weight of Lactuca sativa decreased slightly when nitrogen fertilizer was increased to 170 kg/hm^(2).
