仿丰产沟渗水地膜覆盖栽培技术研究

Study on a new plastic film covering technique

在总结丰产沟技术和地膜覆盖技术的基础上 ,构想出仿丰产沟渗水地膜覆盖栽培技术 ,阐述了这一技术的创新点与技术要点。经多年的小区试验大田示范表明 :这项技术和现行地膜覆盖技术相比 ,玉米苗期长势良好 ,产量增加 30 %以上。该技术的经济效益高 ,其增产机理表现在微地形集流渗水、地积温增加、作物根际微生态环境改善三个方面。

To improve the utilization of rainfall resources, a new farming technique was put forward on the basis of two ready techniques, and its key ideas and main points were listed. The test results in several places in many years showed that there was striking increase in maize yield compared with the conventional farming. The reason was that it coud collect small rainfall, increase soil temperature, and modify micro-organism etc.
