| 摘 要： | 风沙半干旱区生态环境脆弱,耕作方式落后,年降水量少且变率大.地膜覆盖技术是解决风沙半干旱区粮食产量不稳和土壤易干、易旱的有效途径.采用对比设计方法,以裸地栽培为对照,研究了风沙半干旱区地膜覆盖技术对花生产量与光合特性的影响.结果表明:覆膜花生平均LAI大2.4,光合速率高2.9 μmol CO2/(m2·s),气孔导度多0.05 mol H2O/(m2·s),胞间CO2浓度高18.5 μmol CO2/mol,蒸腾速率高1.4 mmol H2O/(m2·s),叶绿素含量低0.1,最终产量提高42.8%.说明地膜覆盖花生生长旺盛,地面覆盖程度大,除叶绿素含量稍低外,其它几项光合生理指标和产量均好于裸地花生. |

| Abstract: | The ecological environment is fragile in sandy and semi arid regions.The tillage methods are laggard.The average annual precipitation is little and the change rate is large.Used the uncovered cultivation as control,the film-mulching technique is an effective way to solve the unstable grain yield and soil easy to drought.The effects of film-mulching technique on peanut yield and photosynthetic characters in sandy and semi arid regions were studied by the method of contrastive design.The results indicated tha... |
