摘　　要：在克拉玛依市农业开发区,6—8月林木生长季用培养55d的白榆营养钵播种苗造林,造林前后定株、定叶、定时测定试验苗木的生理生化特性。结果表明：造林后1~2d白榆营养钵播种苗的生理生化指标降低,栽后一般第2~3天开始上升,第3~4天可以恢复到栽植前的生理水平,白榆苗木缓苗期在4d左右,造林成活率达95%。该造林技术与传统造林技术相比,林木缓苗期短,造林成活率高,可延长造林时间50~70d。因此,西北干旱地区可采用全生长季造林技术进行大规模造林。The experimental material is nutritional bowl seedlings which planted 55 days in the same year on the agricultural development area in Karamy.This experiment purpose lies in delaying afforesting time.Using nutrition tray,grown Ulmus pumila seedling to afforest in growing season from June to August,and the physiological and biochemical characteristics of experimental seedlings were measured.The result showed that： physiological and biochemical indexes reduced within one or two days after afforestation,but these indexes would go up after two or three days and could recover to the normal level after three or four days.The recovering stage of Ulmus pumila is about 4 days and the survive rate achieve 95%.Comparing with traditional afforestation technology,this technology had a short recovering stage and high survival rate of forestation and can delay afforesting time about 50—70 days,so it would be realistically significant in cosmical afforestation.
