- 摘要:
- 为保证2BMFJ-3型麦茬地免耕大豆精密播种机播种大豆的性能，确定一种适合于该播种机的机械式精密排种器，参照GB6973-2005《单粒（精密）播种机试验方法》，以窝眼轮式、倾斜勺式和勺轮式排种器为研究对象，在JPS-12计算机视觉精密排种器性能检测试验台上实施了对比试验研究。结果表明：在作业速度3~6 km·h-1、粒距8 cm条件下，勺轮式排种器的排种性能最优，其合格指数87.8%~98.9%，重播指数0.5%~1.1%，漏播指数低于12%，变异系数小于16%，各项指标均达到国家标准优等品水平。
- Abstract:
- The comparative tests have been carried out on test-bed of JPS-12 seedmetering by GB6973-2005,Single(Precision) Seeder Experimental Method,of which the seedingmetering of socket-roller,inclined spoon and spoon-roller were selected as the object.The objective was to improve the soybean seeding performance of 2BMFJ-3 type no-till precision planter in wheat stubble fields,and determine a kind of reasonable seeding-metering for the planter.The result indicated that the seeding performance of spoon-roller was the best,while operation speed was 3-6 km·h-1 and space was 8 cm,meanwhile qualified rate was 87.8%-98.9%,multiple rate was 0.5%-1.1%,missed rate was lower than 12% and variable coefficient was less than 16%,and each index attached the level of superior quality.
