Application Experiment of Straw Decomposing Inoculants in Wulan

In Qaidam area,setting conventional fertilization of no straw,conventional fertilization+straw of no decomposing inoculants,conventional fertilization+Straw+Jingfuyuandecomposing inoculants 2 kg/667m2+Urea 5 kg/667m2.Adopting single-factor randomized design.The results showed that compared with Jingfuyuandecomposing inoculants 2 kg/667m2+Urea 5 kg/667m2 with fertilization of no straw and without application of straw decomposition agent.The effects of increasing the soil physical and chemical property were the best.Meanwhile,the effects of increasing the total nitrogen,available phosphorus and potassium were also the best.There were no significant differences of yield of after wheat grain through above three treatments.
