Adopting the 6: 2 wheat-maize interplanting technique on the valley-dam land and valley plain in mountainous areas can yield 346. 8kg wheat and 660. 9 maize,that is 1000kg/mu annually,which can be ascribed to its meeting the requirements of wheat and maize in the developmental regulations for high yield by predating sowing time by 20 days and increasing the available accumulated temperature by 300℃ in maize and 15 days and 200℃ of prewinter accumulated temperature in Wheat. Compared with the 9: 4 and 3: 1 wheat-maize interplanting techniques,this technique has better effects on increasing accumulated temperature yields and profits. It may be an efficient way to take advantage of available accumulated temperature and a strategic measure for developing high-yield and high-profit agriculture.

山区沟坝川地小麦套玉米“六二”式条带种植方式,把玉米套种时间提早了20天,有效积温增加300℃,小麦播期提早一个节令,冬前积温增加200℃,较好地协调了小麦、玉米高产生长发育规律需求,达到小麦346.8kg、玉米660.9kg,亩产一吨粮。与“九四”式、“三一”式条带种植方式相比,具有较好的增温效应和增产增收效果,是解决山区沟坝川地生育期和积温一茬有余、两茬不足的有效途径,也是山区发展高产高效农业的一项战略性措施。

According to the theories of agricultural system engineering, the key agronomic practices influencing yield such as sowing time, density, fertilizer management in mechanized line sowing wheat fields or density, fertilizer management in mechanized direct sowing rice fields under mechanical minimum tillage were studied. As a result, the optimized combinations of agronomic practices for attaining wheat yield more than 6000 kg/hm2, rice yield more than 8500 kg/hm2 and annual total crop yield more than 14500 kg/hm2 were obtained. In the meanwhile a complet set of stable high-yield culture techniques in mechanical direct seeding rice fields and line seeding wheat fields under mechanized minimum tillage were formed.
