山东省是全国棉花重点产区之一,历年种植面积都在2,000万亩左右,但其种植机械化的程度,比其他主要作物要低。1979—1983年,在9个主要产棉区17个重点产棉县,进行了棉花种植机械的选型试验,选出了2BZ—4型通用机架为当时的推广机型。近几年,随着农村生产体制的变化,棉花精、少量播种机和一些小型的人畜力棉播机也很受棉农欢迎。据1986年底不完全统计,近几年山东全省机播棉花295.1万亩,

In 1979-1983, the selection of cotton cultivation machines was carried out in 17 key cotton producing counties in 9 major cotton producing areas. The 2BZ-4 universal rack was selected as the promotion model at that time. In recent years, with the change of rural production system, cotton sperm, a small number of seeders and some small people-livestock cotton sowing machines are also very popular with cotton farmers. According to incomplete statistics by the end of 1986, in Shandong Province in recent years, 2.951 million mu of cotton were planted,
