Abstract

purpose: to study changes of soil moisture and temperature during plant dormancy under different film covering conditions. Method: observe the soil water content and temperature under the condition of bare land (CK), transparent film covering (TF) and black film covering (BF) in the wild. Result: during the dormant period, the average soil moisture content under TF condition is 48.9%~53.6%, higher than that under CK condition, which means that water is better conserved under film covering; soil temperature under the depth of 15cm has no significant difference between TF and BF condition, which means the effect of film covering lasts for 15cm. Conclusion: Film can increase soil water and temperature within the depth from 0 to 20cm, and promote deep water infiltration. Compared with TF condition, BF condition is more favorable to the increase of temperature and to stable temperature.
