摘要
免耕播种是保护性耕作技术最重要的作业环节之一,为了在一年两熟旱作区选择适合的播种机来实施保护性耕作技术,对国内目前可选用的JOHNDEERE1590型小麦免耕播种机、2BMD-12型小麦对行免耕播种机、2BMFS-6/12型带状浅旋免耕播种机在3种地表覆盖状况下进行田间播种适应性试验,结果表明:参照播种机国家标准和农业部农机试验鉴定总站对小麦免耕播种机播种质量的检测指标,3种免耕播种机在秸秆粉碎覆盖地面条件下基本上都能满足播种要求。JOHNDEERE1590型小麦免耕播种机不适合于在直立秸秆情况下进行播种,适于大面积地块作业。2BMD-12型小麦对行免耕播种机和2BMFS-6/12型带状浅旋免耕播种机在3种地表状况下都能播种,且其设计和应用主要针对于在直立秸秆情况下进行播种。JOHNDEERE1590型小麦免耕播种机价格高,在中国地块小,作业时间短的情况下效率难以充分发挥。用户应根据不同地区地表覆盖状况、地块的大小、经济状况等选择适合的小麦免耕播种机来实施和推广保护性耕作技术。
No tillage planting is one of the important tasks in conservation tillage technique and the performance of no-tillage drills directly affects the realization of that technique. In order to select suitable no-tillage drills for areas with two ripe crops a year, suitability experiments have been done using JOHN DEERE 1590, 2BMD-12 No-Tillage Drill and 2BMFS-6/12 No-Tillage Drills in three different surface condition fields. The results of field test show that three kinds of no-tillage drills can all meet the Natl. standards of drill testing when the corn stalks were chopped and returned to the field. JOHN DEERE 1590 No-Tillage Drill could not plant under the condition of the corn stalks standing in the field. 2BMD-12 No-Tillage Drill and 2BMFS-6/12 No-Tillage Drill with Strip Rotary Tiller can both work under three different soil surface conditions. JOHN DEERE 1590 No-Tillage Drill does not adapt to be used in China because the price of the machine is too high, the plot of China is small, working time is short, therefore, the drill capacity could not be fully realized. It should base on the field surface condition, the size of plot and the economic status and so on to select adaptive wheat no-tillage drills for areas with two ripe crops a year.
