Long term no-till (NT) farming can improve the CH4 oxidation capacity of agricultural lands through creation of a favorable soil environment for methanotrophs and diffusive gas transport. However, lim...
在内蒙古、新疆等大型农场，随着大马力拖拉机的增加，中小型小麦免耕播种机已经不能满足动力发展的需要，限制了保护性耕作的推广实施，急需研究与大马力拖拉机配套的大型免耕播种机。本文设计了2BMG-24型小麦免耕播种机，采用控制式密齿型排种器、波纹圆盘和双圆盘组合式开沟施肥播种单体，实现了精少量排种、破茬开沟和种肥分施的小麦免耕播种。田间试验表明：播种深度合格率为91%；排种均匀性变异系数为28%；种子破...
小麦免耕播种机驱动链式防堵装置设计（Design of the Powered-chain Anti-blocking Mechanism for Wheat No-till Planter）
小麦 免耕播种机 保护性耕作 驱动链式
2009/11/3
针对我国华北一年两熟地区玉米秸秆覆盖量多，小麦免耕播种易堵塞的问题，提出了驱动拨指链抛茬和刀刃型开沟器切茬相结合的新型防堵原理，设计了免耕播种机驱动链式防堵装置。通过分析防堵装置的运动过程，确定了驱动链、拨指和刀刃型开沟器等关键部件的参数。田间试验表明，驱动链式防堵装置能够有效解决秸秆堵塞问题，保证小麦免耕播种机的通过性。由于及时清除刀刃型开沟器前方的玉米秸秆残茬，开沟阻力降低了12.3%。相比条...
玉米垄作免耕播种机油耗试验与分析（Fuel Consumption Test and Analysis for the Ridge-till and No-till Corn Planter）
垄作 保护性耕作 播种机
2009/11/3
保护性耕作技术在我国垄作地区难以推广的主要原因是缺乏在有根茬原垄上确保播种质量的免耕播种机。针对以苗带浅旋处理玉米根茬为机理的2BML-2型垄作免耕播种机，进行了田间油耗试验。试验结果表明：在开沟器、覆土装置、镇压装置等部件工作参数一定时，影响播种机油耗的主要因素中，根茬处理装置的旋耕入土深度影响最大，其次是旋耕幅宽，然后是机组前进速度；在适合范围内，机组前进速度越大，油耗越小；本播种机能有效减少...
小麦免耕播种机防堵装置性能对比试验（Comparative Experiment on Anti-blocking Mechanism for Wheat No-till Planter）
小麦 免耕播种机 防堵装置 保护性耕作 试验
2010/2/26
驱动链式、驱动圆盘式和带状旋耕式3种小麦免耕播种机防堵装置具有不同性能和适应性。通过田间性能对比试验，分析了装有不同防堵装置的小麦免耕播种机通过性、土壤扰动量、单位油耗、返青期小麦苗情和产量。试验结果表明：3种防堵装置在不同秸秆覆盖量的免耕地均能满足通过性要求，但在100%秸秆覆盖量情况下，带状旋耕式防堵装置通过性最好，驱动链式和驱动圆盘式防堵装置存在轻微堵塞；在土壤扰动量、单位油耗、小麦返青期苗...
免耕覆盖地秸秆行茬导航路径的图像检测（Detection of Stubble Row and Inter-row Line for Computer Vision Guidance in No-till Field）
保护性耕作 农业机械 自动导航
2009/8/11
提出了秸秆行茬视觉导航方法，引导农机具在根茬行间作业以防止堵塞，并对玉米直立根茬导航路径的检测方法进行了研究。选取了图像的彩度信息作为研究对象，通过多种自动阈值选取方法的对比试验和分析，采用迭代法对根茬图像与土壤背景进行了有效分割，并采用2次腐蚀处理去除噪声，通过膨胀处理填充目标区域孔洞；使用了过已知点的Hough变换检测出玉米直立根茬行间及行茬直线。田间试验表明，该方法能够有效地提取出秸秆行茬导...
