摘要
提出了适合我国北方小麦、玉米一年两熟地区玉米整秸覆盖、小麦免耕播种的一种新的作业工艺,并设计了相应的玉米秸秆梳压机、小麦免耕播种机。试验表明,该机组各项作业指标均达到现代农艺技术要求。配套机具充分利用了农村小型拖拉机保有量多的特点,具有良好的推广应用前景。
A new technology to sow winter wheat with no-tillage was studied under the conditions of returning the whole corn stalk to field in the area of wheat/corn two crops one-year rotation in the northern part of China. A special attachment was designed to press maize stalk to soil surface and a sowing machine was developed to sow winter wheat under no-tillage condition. The field investigation results showed that the performances of the machinery were labor and energy saving. The conservation tillage and soil moisture preservation were achieved. This new technology will make full use of the small tractors widely available at the villages. Therefore, this technique has the potential to be extended in the northern part of China.
