Abstract：In order to explore the effects of plastic-film mulching on Bradysia odoriphaga and high temperature treatment on leek growth,the field tests of plastic-film mulching were carried out in Shouguang and Chiping of Shandong Province in the spring of 2017.Meanwhile,we studied the effect of soil temperature on growth of leek in high room temperature treatment.The results showed that,in the condition of soil temperature of 5 cm depth reaching 39℃ over 2 hours,the control effects of plastic-film mulching on Bradysia odoriphaga could reach up to 100％ in leek fields.The soil temperature arriving at 52℃ was not beneficial to the leaf and root length of leek.Therefore,the appropriate time of plastic-film mulching and film-uncovering should be chosen in field,which could ensure the soil temperature arriving at 39℃ over 2 hours and avoiding over 52℃.
