| 摘 要： | 为解决作物播种过程板结,有效延伸作物播种时间,缩短出苗时间,提高出苗率,实现合理的群体构建。通过制定技术方案,研制开发出由连接构件、调节构件和耧耙构件组成的“农作物播种过程板结耧耙装置”。该装置经在播种期降雨较多年份与已有的“旋耕施肥播种镇压一体机”配套使用,其耧耙构件的耙齿入土深度一致,且符合农艺技术要求,有效解决了播种过程板结,提高了出苗率;该装置具有结构简单、安装简便、易操作等特点。该项研究是对“旋耕施肥播种镇压一体机”性能及功能的进一步完善,可为播种保苗及构建合理群体提供技术支撑。

| Abstract: | To solve the soil hardening in crop seeding process, effectively extend crop sowing time, shorten the emergence time, improve emergence rate and achieve reasonable population construction, through formulating technical scheme, ‘the loosen-rake device based on soil hardening in crop sowing process’ was developed, which was composed of connecting components, regulating components and rake components. The device was used in combination with the existing ‘rotary tillage, fertilization, sowing and compacting unity machine’ during sowing period in more rainfall years. The rake teeth had the same depth into the soil and met the requirements of agronomic technology, which could effectively solve the soil hardening in sowing process and improve emergence rate. The device had the characteristics of simple structure, simple installation and easy operation. The research can further improve the performance and function of ‘rotary tillage, fertilization, sowing and compacting unity machine’, and provide technical support for seeding, seedling protection and reasonable population construction. |
