为了适应城市郊区大面积蔬菜机械播种的需要,我所于一九七二年试制成2BS—6型蔬菜播种机(见图1)。通过几台样机的多点田间试验表明,机具工作性能比较稳定,作业质量符合农业技术要求,一九七三年就开始在锦州地区初步进行推广使用。 In order to meet the needs of large-scale planting of vegetable machinery on the outskirts of the city, I commissioned a 2BS-6 vegetable seeder in 1972 (see Figure 1). Several field trials conducted by several prototypes showed that the working performance of the equipment was relatively stable and the quality of the work accorded with the requirements of agricultural technology. In 1973, it was initially started to be used in Jinzhou area.
