2BJYM-4型玉米大豆套播精量播种机的研究

Research on 2BJYM-4 Type Precision Seeder for Interplanting Corn with Soybean

玉米大豆间作种植是一种有效的增产增收技术,但是一次同时完成玉米大豆播种的播种机械尚未成型。为解决这一问题,设计研制出了2BJYM-4型玉米大豆套播精量播种机,可同时实现玉米大豆的精量播种。本文重点介绍了该播种机的构成、工作过程和主要机构,并对该机的播种性能进行了田间试验。结果表明:该机各项性能指标均达到了玉米大豆套播精量播种的技术要求,具有良好的工作可靠性、稳定性和适应性。该播种机的成功研制,为解决玉米大豆套播精量播种机械化问题和促进玉米大豆间作套种模式的推广,提供了装备技术支撑。

Intercropping corn with soybean is an effective increase production technology, but the seeder which could accom- plish sowing corn and soybean at once has not yet formed. In order to solve this problem,2BJYM4 type precision seeder was designed and manufactured, it could realized precision sowing corn and soybean at the same time. The paper introduced the structure ,working process and main mechanism of the seeder. Field trials showed all performance indicators of the seeder reached technical requirement of precision sowing for interplanting corn with soybean, and it had the good reliability, stability and adaptability. The seeder would promote the popularization for intercroooing corn with soybean.
