我国旱作地区坐水播种机械的研究

摘要

Irrigating-sowing is a drought-defying sowing suitable for arid and semi-arid areas in North China.Its effects of yield increase and water saving are obviously,and it is suitable for China conditions.In this paper, the theory and re-lated technology development of irrigating-sowing is introduced, the research and application status of irrigating-sowing machine were discussed.Analyzed the main types and technical characteristics of China ' s irrigating-sowing machine in detail, and the problems and reasons with current irrigating-hole-sowing machines need to be solve were put forward.At the same time,the development direction of irrigating-sowing machinery in the future is indicated.%坐水播种机械是我国典型的行走式节水灌溉机具,适用于我国北方干旱、半干旱地区抗旱播种,抗旱增产效果明显. 为此,介绍了机械化坐水播种技术的原理、产生及发展,分析了我国坐水播种机械的研究与应用现状,探讨了我国穴灌坐水播种的主要机型及技术特点. 同时,针对目前穴灌坐水播种机存在的问题,提出了我国坐水播种机械的发展研究方向.
