目前,黑龙江省水稻种植面积已超过150万hm~2,大部分稻田也已达到方条化、大块化和标准化。联合收割机高效率作业的基础条件虽已形成,但由于黑龙江省霜冻和大雪天气来的早,适合直收水稻的时间短,一般只有15d左右。联合收割机的利用率低,适应性差。为此,我厂研制了4GLS-180型割晒台和DS-120型带式拾禾器,于1999年9月完成小批量试制并投放市场。这两种机装备
At present, the area under rice cultivation in Heilongjiang Province has exceeded 1.5 million hm 2, and most of the paddy fields have also been square-bariled, chunky and standardized. Although the basic conditions for the high efficiency operation of the combine harvester have been formed, due to the early onset of frost and heavy snowfall in Heilongjiang Province, the time for direct harvesting of rice is short, usually only about 15 days. Combine harvesters have low utilization and poor adaptability. To this end, I plant developed 4GLS-180-type cutting planes and DS-120-type belt-type Wo Wo, in September 1999 to complete a small batch trial and put on the market. These two machines are equipped
