随着联产承包责任制的全面落实,农民以户为单位从事小面积分散作业,要求使用小型收割机。1983年我省水稻播种面积为520万亩,今后还将大幅度增长。但水稻收割主要靠人工,效率低、成本高、浪费严重、劳动强度大。当前,因收割技术落后限制了水稻面积的增长,故发展小型收割机是势在必行。 With the full implementation of the system of contract responsibility for contract-based production, farmers engaged in small-area decentralized operations on a household basis require the use of small harvesters. In 1983, the sown area of ​​paddy rice in our province was 5.2 million mu and will increase substantially in the future. However, the main harvest of rice by artificial, low efficiency, high cost, serious waste, labor-intensive. At present, the development of small harvesters is imperative due to the limited area for rice harvest due to backward harvesting techniques.
