玉米整秸覆盖地小麦免耕播种技术初步研究

在玉米整秸覆盖条件下，在玉米行间免耕播种小麦是中国北方小麦、玉米一年两熟地区小麦免耕播种的一种全新方法。介绍了玉米整秸覆盖地小麦全免耕播种技术、所需机具、作业工艺、技术要点及试验结果。研究结果表明：该项技术及配套机具能够保证小麦免耕播种、施肥的农艺技术要求，且具有蓄水保墒效果；作业收费较传统的作业方式降低50%左右。具有省工、省力、省时、省钱、节能、增产、增收之功效；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。

No-tillage seeding technique for wheat under the bestrow of the whole corn stalk

A new technique for covering the whole corn stalk and no-tillage seeding of wheat between corn rows in wheat/corn two crops one-year area was studied in the north of China. This paper emphasized introducing the no-tillage seeding techniques of coving whole corn stalk, necessary agricultural machinery, operational technology and experimental results. The study shows that the technique and its necessary agricultural machinery can meet the agricultural requirement of no-tillage seeding and fertilizer application,and have an effect on storing water and preserving moisture of the soil. The input can be decreasedby about 50% compared with the traditional method. It can save labor and time input, increase profit and save energy. Its attached agricultural machines make good use of the characteristics that there are more small power tractors in the village. Therefore this technique has been widely extended in China.
