采用土样中5×102（T1）、5×103（T2）、5×104菌落/cm3（T3）的棘孢木霉分生孢子悬浮液，诱导青蒿60 d，分析诱导后青蒿的生长量以及土壤水解氮的变化规律。结果表明：T2诱导效果最佳。 T2的诱导，青蒿的主茎高生长量在8月10-20日达到最大、茎基粗在诱导后20 d内达到最大值，两者分别为21．41、0．84 cm，是对照组的1．38、1．47倍；T2的诱导，单株青蒿根的鲜质量平均值130．776 g，比T1、T3的诱导，分别增加了88．74％和58．45％，而且生长的时间长、提升的幅度大。用T2诱导，青蒿30 d的土壤中水解氮质量分数，与不施用木霉且不栽培青蒿的土壤、施用T1的木霉但不栽培青蒿的土壤、施用T2的木霉但不栽培青蒿的土壤相比，分别减少19．62％、10．4％、21．03％。棘孢木霉，不仅可以促进青蒿的生长，还可以改善土壤中的水解氮质量分数，最适棘孢木霉的量浓度为5×103菌落/cm3。

With three experimental groups of T1(5×102 cfu/cm3 soil), T2(5×103 cfu/cm3 soil) and T3(5×104 cfu/cm3 soil) underwent60 days of inducing Artemisia na nua by three different contents of Trichoderma asperellum conidial suspension . An experiment was conducted to study the Artemisinin growth and the available nitrogen content in the soil.Group T2 is the most suitable content and the effect of inducing on Group T2 is significant.The plant height of A.annua reachedthe maxi-mum from August 10 to August 20 and the stem base perimeter reaches the maximum.When the plant height increased, the stem perimeter increased actually 1.38 and 1.47 times than that of control.The average fresh weight of root per A.an-nua plant of Group T2 was 130.776 g, increasing by 18.87% and 15.84%compared to Group T1 and Group T3 .The more time it grows, the more range will improve.After 30 days of inducing, in terms of soil nitrogen hydrolysate, the available nitrogen content of the pot soil of Group T2 reduced by 19.62%compared to Group A (bare soil with neither Atr emisiaan-nua nor inducing), reduced by 10.4%compared toGroup A1(pot soil with T1 inducing but without Artemisia annua) and reduced by 21.03% compared to Group A2(pot soil with T2 inducingbut without Artemisia annua).Therefore, T.asperel-lum improves not only Artemisia annua growth, but also plays a positive role in promotingthe available nitrogen content in the soil, and the best inducing content is 5×103 cfu/cm3 soil.
