为推广大豆“三垄”栽培法,我场1987～1988年引进了23台2BJGL—6型精密联合耕播机,进行推广使用。1987年播种大豆2580亩,1988年播种大豆6万亩,占大豆播种面积的41.63%。经两年的使用,证明该机有良好的使用性能和经济性能。一、使用情况1.应用该机播种大豆有明显的增产效果。从下表中可以看出,应用该机播种大豆,各项产量因子均高于传统的作业方法播种的大豆,平均增产30.83%。 To promote soybean “three ridge ” cultivation method, our field from 1987 to 1988 introduced 23 Taiwan 2BJGL-6 precision combined tillage machine, to promote the use of. Sowing 2580 acres of soybean in 1987, Sowing 60,000 acres in 1988, accounting for 41.63% of the sown area of ​​soybean. After two years of use, that the machine has good performance and economic performance. First, the use of the situation 1. The use of the machine sowing soybean production has obvious effects. As can be seen from the table below, all the yield factors of sowing soybean by this machine are higher than that of soybean sown by the traditional operation method, with an average increase of 30.83%.
