农作物秸秆还田是保证农业持续高产、稳产的有效途径之一,是增加土壤有机质,改善土壤结构的一项重要措施,因此,必须长期坚持下去.为了做好这项工作,近年来.我们推广使用了石家庄市农业机械厂生产的4Q—2型锤爪式秸秆切碎切.一、技术性能该机与55千瓦拖拉机配套;生产效率为0.9—1.0公顷/小时;工作幅宽2米;割茬高度2—8厘米;切碎长度;小麦≤15厘米;玉米≤10厘米;抛撒宽度2—3米.二、主要优点1.作业项目范围广.该机对玉米、油葵、棉花、小麦等软、硬秸秆,均有良好的切碎性.2.适应性好.适应于田间直立或铺放的任何作物秸秆.3.作业质量好.该机割茬低,切碎性好,抛撒均匀,对来年的机械整地、播种、耕作无任何影响.4.技术较先进.该机较好地解决了“L”型切碎机仅适合硬质秸秆的局限性,是目前与大中型拖拉机相配套较理想的机具.
Crop straw returning is one of the effective ways to ensure continuous high yield and stable yield of agriculture. It is an important measure to increase soil organic matter and improve soil structure. Therefore, we must persist for a long time. In order to do this well in recent years, we promote Shijiazhuang Agricultural Machinery Factory used the production of 4Q-2 hammer claw straw chopped cut. First, the technical performance of the machine and 55 kilowatts tractor matching; production efficiency of 0.9-1.0 hectares / hour; working width of 2 meters; cutting Stubble height 2-8 cm; chopped length; wheat ≤ 15 cm; corn ≤ 10 cm; throwing width of 2-3 meters. Second, the main advantages of a wide range of job items. The aircraft corn, sunflower, cotton, wheat Such as soft and hard straw, have good shredding .2 adaptability.Approved for any crop stalks standing or laying in the field .3 good job quality. The machine cutting stubble, shredding is good, throwing Uniform, the next year, machinery planting, planting, farming without any impact .4 advanced technology.This machine to better solve the “L” type shredders only suitable for the limitations of hard straw, is the current large and medium-sized tractors Supporting the ideal machine.
