2BFS-8型水稻芽种播种施肥机设计与试验

设计了2BFS-8型水稻芽种播种施肥机，可一次完成平田、开沟（厢沟、畦沟、肥沟）、作畦、播种、施肥、压种、盖肥等工序。采用振动阀门的槽轮排种器，可实现水稻芽种定量精密分行条播，并防止伤芽和断条。采用常规槽轮排肥器与施肥开沟器，可实现常态化肥分行深施。由组合式开沟器形成的多沟并举，有利于水肥有效管理和光、温充分利用。室内台架和田间生产试验表明，该机主要技术性能指标均达到国家相关标准规定。

Design of Rice Bud Seed Sowing and Fertilizer Machine

2BFS-8 rice planting fertilizer machine was developed and it could level the paddy fields, open the furrow, form the ridge, sow, fertilize, press down the seeds and fertilizer simultaneously according to the requirement of rice planting. Seeds were drilled in the ridge and fertilizer was manured in the fertilizer ditch. Improved seed metering device could effectively prevent the clogging of rice seeds. The ditch system enabled the effective management of water and fertilizer to the paddy fields. Laboratory and field tests showed that this machine has fully reached the relevant national standards requirement.
