Abstract：To reduce the adverse effects of chilling injury on wheat in winter,the wheat yield and composition,soil compaction and respiratory rate,photosynthetic rate of wheat leaves were investigated under different treatemnts (local cultivation measure as control,prevention treatment,remediation treatment) by field experiment from 2015 to 2016.The results showed that grain yield and spike number of prevention and remediation treatments were significantly improved compared with control,the increase rate of yield were 266.56％ and 130.58％ respectively,and the increase rate of spike number were 129.27％ and 96.98％ respectively.Prevention treatment significantly improved spike number and grain yield by 16.39％ and 58.97％ compared with remediation treatment.The orders of soil compaction in 0-20 cm soil layer at jointing stage and harvesting stage and photosynthetic rate of wheat flag leaves were prevention treatment ＞ remediation treatment ＞ control.The order of soil respiration rate was prevention treatment ＞ control ＞ remediation treatment,the soil respiration rate of prevention treatment significantly increased by 11.71％ compared with control.The results showed that the prevention and remediation treatments had certain effect of disaster reduction,and the effect of the prevention treatment was superior to the remediation treatment.
