新型紫花苜蓿外槽轮排种器的试验与分析

摘要

When we planting alfalfa ,each hectare need a small amount of seed , if we use the existing external force feed for sowing,it is very hard to meet the practical sowing requirement ,in this argument,the author had improvement some Structure of the existing external force feed ,and do experiment on the according test bench .from the outcome of the ex-periment we can know that the later seed-metering device can work very well .%由于紫花苜蓿播量较小，采用现有的外槽轮式排种器进行播种时，很难满足实际播种量的要求。为此，在结构上对现有的外槽轮排种器进行改进，并在排种器试验台上进行排种试验。试验结果表明：在保证排种均匀性和播量精度的情况下，能够很好地控制排种器的实际播量，满足紫花苜蓿播种需求。
