【摘要】 地膜小麦和露地小麦土壤温度随生育阶段推后均呈增加趋势 ,拔节之后增加最快 ;与露地小麦相比 ,地膜小麦增温最明显的阶段是在出苗到拔节阶段 ,之后增温减慢。不同日测定时间土温动态变化不同。不同天气状况的增温效果大小顺序依次是晴天 >阴天 >雨天。地膜小麦土壤温度日变化最高温度出现在 14:0 0 ,而最大温差出现在18:0 0。更多还原

【Abstract】 The temperature of soil of dibbling wheat in film mulched field (DM)and no film mulched field(LD)was obviously increased, as the wheat development stage was delayed.The temperature of DM was abviously increased before shooting period, and after that, the temperature was unremarkably increased. The temperature increaced stage of dibbling wheat in film mulched field was between seedling shooting period, then it was reduced. The tendency change of temperature of soil was different at the different day for temperature increased was that sunny days was better than rainy and cloudy days. The most temperature of soil of day change was at 2:00 p.m. and the most difference in tempreture was at 6:00 p.m. of dibbling wheat infilm mulched field.更多还原
