- 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.
