2BMFJ-3（B）型茬地大豆免耕覆秸精播机性能试验研究

摘要

按照国标标准（（GB／T6973—2005单粒（精密）播种机试验方法》，设定理论株距8cm和6cm，理论播深3～5cm，对2BMFJ-3（B）型茬地大豆免耕覆秸精播机进行田间性能测试，进而对其作业质量进行等级评定。结果表明：当理论株距为8cm和6cm时，粒距合格指数、重播指数、漏播指数及株距变异系数均达到了国家部颁标注优等品要求水平；当理论播深为3～5cm时，播深合格率达到一等品的要求水平。%The performance of 2BMFJ-3（B） no-tillage soybean precision seeder in stubble field was tested according to the testing methods of single seed drills, and the theory spacing were set to 8cm and 6cm, the theory sowing depth was 3-5cm, then the showed that the qualification rate of spacing, operation the miss quality of the seeder could be classified. The result rate and the muhiples rate met the requirement of superior class product of the standard when the theory spacing were 8cm and 6cm, also, the sowing depth attained the require of first class product when the theory sowing depth was 3-5cm
