为了在黄淮海旱作区更好地实施保护性耕作技术,同时又能满足该地区农民对大豆免耕播种机的使用需求,参照免耕播种机的国家标准和农业部农机试验鉴定总站制定的免耕播种机播种质量的检测指标和方法,对目前在黄淮海地区使用的2BMFD-6/12型全还田防缠绕免耕播种机和2BMFJ-6型麦茬地大豆免耕覆秸施肥播种机进行了田间试验,考察了这两种大豆免耕播种机在黄淮海地区的适应性,并对这两种机型的性能进行了分析。通过对两种大豆免耕播种机的机具通过性、播种均匀性、种肥深度、晾籽情况等性能的研究,这两种大豆免耕播种机虽然工作原理不同,有各自的优缺点,但这两种大豆免耕播种机的性能参数均能达到国家标准,个别指标甚至优于国家标准,在黄淮海地区的适应性都比较强,均能够实现精量播种。
In order to better implement the conservation tillage technology in the Huanghuai sea-crop region, at the same time, it can meet the farmers’ needs for soybean no-tillage seeder in the region, refer to the national standard of no-tillage seeder and the agricultural trial identification terminal set by the Ministry of Agriculture No-tillage planter sowing quality indicators and methods of detection, the current in the Huang-Huai-Hai region 2BMFD-6/12 full field anti-wrap no-tillage and 2BMFJ-6 wheat stubble field no-tillage straw fertilizer applicator Field experiments were conducted to investigate the adaptability of the two soybean no-till planters in Huang-Huai-Hai region, and the performance of the two models was analyzed. Through the study on the performance of two soy no-tillage planter sowing machines, the uniformity of sowing, the depth of seed fertilizer and the condition of airing seed, the two soy no-tillage planter has its own advantages and disadvantages though its working principle is different Both of these soybean no-tillage planter performance parameters can meet the national standards, individual indicators even better than the national standard, in the Huang-Huai-Hai region are relatively strong adaptability, are able to achieve precision sowing.
