1ZL—4.2型联合整地机是由中国农机院和佳木斯北方机械厂联合研制的,该机用2～3种不同性能的工作部件进行联合作业,能有效地代替几种单一机具的多次分段作业,符合当前大力推行的土壤耕作制度和少耕法。经四年研制、三轮样机的试验,表明该机具能够适应多种耕作的要求。 1ZL-4.2-type joint preparation machine is jointly developed by China Agricultural Machinery Academy and Jiamusi Northern Machinery Plant. The machine is operated jointly with 2-3 kinds of working parts with different performances, which can effectively replace the multiple sub-machines Operation, in line with the current vigorously promote the soil cultivation system and less tillage. After four years of development, three rounds of prototype tests show that the machine can adapt to a variety of farming requirements.
