宝泉岭农场玉米深松放寒作业是玉米高产栽培技术中抢积温、促苗早发的有效措施。因秸秆还田使土壤耕层里混有大量的秸秆,使玉米播种后深松放寒作业中,出现拖堆雍土埋苗和作业效率低的新问题。对现有中耕机进行技术改造升级,在大深松杆尺前增加1个直径600 mm的缺口切草圆盘刀,切断耕层中没有腐烂的秸秆,减少深松杆尺挂草,能较好地解决拖堆雍土埋苗的问题。在大深松杆尺后两侧增加2个直径400 mm圆盘护苗器,能挡住因拖拉机提高作业速度后,大深杆尺翻起土块伤苗的问题。此项技术改造,能满足新形式下农业可持续发展提出的新目标、新任务和新要求。
Baoquan Ridge farm corn subsoiling operation is high yielding corn cultivation techniques to accumulate temperature, and promote early seedling effective measures. Due to the straw returning to the soil, there is a lot of straw mixed in the tillage, so that after sowing the maize sowing and letting go of the cold operation, there will be a new problem of mowing the soil and burying seedlings and low operating efficiency. To upgrade and upgrade the existing cultivator, add a cut-and-cut circular cutter with a diameter of 600 mm in front of the deep pine shaft to cut off the decayed straw in the top layer and reduce the depth of the loose pine rod. Solve the problem of rubbish pile seedlings well. In the deep after the loose rod on both sides of the increase of two diameter 400 mm disc guard, can block due to the tractor to improve operating speed, deep deep rod foot overturned injury block seedlings problem. This technological transformation can meet the new goals, new tasks and new requirements put forward by the agricultural sustainable development under the new form.
