我国旱作地区坐水播种机械的研究

Research of Irrigating-sowing Machinery in China

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。

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 related 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.
