中文摘要	膜下滴灌棉田获得的辐射热量比常规灌溉棉田稍高，以潜热通量的方式消耗的热量花蕾期约占净辐射的61．0％、吐絮期为42.3％，沙漠下垫面条件下产生的干而热的空气块在天气系统运动作用下，经过棉田使潜热通量增加，但膜下滴灌棉田比常规灌溉棉田花蕾期低7％左右，且后期差距加大，使得膜下滴灌棉田的感热通量、波恩比比常规灌溉棉田分别高4．8％-6．4％、0．10．2。其小气候条件优于常规棉田。
英文摘要	Net radiation,Cotton fields under drip irrigation was studied in this paper.The results indicated that contton field under drip irrigation with plastic film acquired slight higher heat than conventional irrigation, the latent heat occupied 61% of net radiation at flowering-bud stages, and 42.3% at boll-opening stages. Dry and hot air block heated by the underlying desert surface which passed cotton field driven by weather system made an increase in cotton field. Latent heat flux in drip irrigation field was 7% lower than conventional irrigation field, this gap was enlarged in late growth period. Sensible heat flux, Bowen ratio in drip irrigation field was higher than conventional irrigation field by 4.8%-6.4%, 0.1-0.2 respectively. Mi- croclimate in drip irrigation field was more suitable to cotton growth than conventional irrigation field.
