小区播种机发展现状与关键部件技术分析OA

The plot seeder was a kind of equipment specially used for new variety cultivation,fine variety breeding and variety comparison test.Accurate breeding test could create high-yield and value-added agricultural products,whose de-velopment was not only related to the progress of agricultural science and technology and national food security,but also directly affected the efficiency of agricultural production and the quality of crop varieties.Compared with artificial or semi-artificial breeding,plot seeder had more advantages in ensuring the consistency of sowing depth and uniformity of sowing,which was the key link to ensure the accuracy and scientific rigor of breeding test.In this paper,the development status of plot seeder at home and abroad was summarized,and the performance and characteristics of mainstream models at home and abroad in recent years were listed.Combined with the research and development status of plot seeder in China,the technical principles of key components such as plot seed supply device,plot seed metering device and plot seed clea-ning device were analyzed.The adaptation difference between plot seeder and field seeder was expounded,and the deve-lopment trend of plot seeder was pointed out.At the same time,some suggestions were put forward for the shortcomings of the plot planter in technology,technology,popularization and application,and the integration of agricultural machinery and agronomy,in order to provide reference for the research and development of products in the field of breeding machi-nery.
