摘要
精密播种是中耕作物播种机发展的主要趋势，其关键部件──排种器的研究现已取得较大进展。本文全面分析了精播排种器的技术性能现状以及提高充种频率的技术措施，并综述分析了排种器试验研究技术及排种理论研究的进展和存在的问题。
The precision planter is a main trend in recent.The study on its key parts,seed-metering divice, has been greatly developed in recent years. In this paper, the atlthors analyse the technical characteristics of various seed-metering devices for precisionplanter and some technical means to realize high filling frequence, also introduce theoutline of test techniques used to study seed-metering device and give a general review ofthe theoretical study on the seed-metering divice of precision planter.
