研究结果表明，水稻品种在旱作条件下同一成熟叶片蒸腾速率（Ｔｒ）覆膜＜ 露地＜ 水田，水分利用率（ＷＵＥ）覆膜＞ 露地＞ 水田，差异显著。叶绿素含量、比叶重、脯氨酸含量及根系呼吸强度覆膜＞ 露地＞ 水田，覆膜抗旱性最强。分蘖期、拔节孕穗期、抽穗开花期、灌浆期耐旱性不同，水分敏感期为孕穗期和抽穗开花期。旱作水稻分蘖能力增强，有效穗增多，但每穗粒数、结实率和千粒重下降。覆膜和水田产量高于露地，覆膜和水田间差异不显著。
The results showed that the transpiration rate (Tr) of paddy field under the condition of dry cultivation was significantly different from that of the paddy field (field exposed, paddy field, WUE, paddy field). Chlorophyll content, specific leaf weight, proline content and root respiration strength of the coating> open field> paddy field, the strongest drought resistance. The tillering stage, booting stage booting stage, heading and flowering stage, drought tolerance at filling stage were different, and the water sensitive stage was booting stage and heading stage. Dryland rice tillering ability increased, the effective panicle increased, but the grains per spike, seed setting rate and grain weight decreased. The yield of plastic film and paddy field was higher than that of open field, and there was no significant difference between plastic film and paddy field.
