摘要
为在江汉平原更好地推广应用保护性耕作技术,满足该地区农民对大豆免耕播种的需求,依据免耕播种机国家标准、农业行业标准及农业部农机试验鉴定总站制定的免耕播种机性能测试指标与方法,对江汉平原地区两种主要的自然留茬地表状态下的2BMFJ-6型多功能原茬地大豆免耕覆秸播种机进行田间性能试验,分析该播种机的作业质量及适应性。结果表明,该播种机在机具通过性、种肥深度、播种均匀性、晾子率等播种性能指标上均高于国家合格标准,性能稳定,适应性较强,能满足江汉平原自然留茬地的大豆精量播种要求。
In order to better promote and apply protective tillage techniques in the Jianghan plain,and fulfil the farmers’demand for no-tillage soybean planters in this area.According to the quailty of no-tillage planters seeding detection index and method of provi⁃sions of the Ministry of agriculture machinery test station and national standards and the agricultural industry standards,the field per⁃formance test of 2BMFJ-6 multifunctional no-tillage soybean straw covering planter was carried out under two kinds of natural stubble surface conditions in Jianghan plain,and the operation quality and adaptability of the seeder were analyzed.The results showed that the planter was higher than the national qualification standard in planting performance indicators such as machine’s trafficability,it depth of seed fertilizer,the uniformity of sowing,and the rate of airing seeds,etc.,This machine has good trafficability and seedability,and has stable performance.It has strong adaptability in the natural stubble land in Jianghan plain and can meet the requirements of soybean precision sowing.
