Mechanization And Conservation Tillage For Wheat And Maize Interplanting

To release the burden of labor intensive and low efficiency manual wheat and maize interplanting, a maize interplanting-fertilizing implement was developed. To match the implement, the tread and ground clearance of small-four-wheel tractor are increased. When sowing wheat, the interplanting line for maize is reserved to mechanize the work for the next crop. Referring to the achievements of conservation tillage on dry land farming, there is a series of work to be done to develop new tillage techniques to adapt to double cropping system of wheat and maize in Shandong province. Such work includes controlling the combine traveling along the line, return the stalk to the field after chopped, subsoiling being done in maize's growing stage. The advantage of subsoiling is to make the soil inter placed with soft and hard strips, which is good for decreasing runoff and vaporizing, and retaining rain. Subsequently, it creates good conditions for crop's growth, and increase the level of mechanization while decreases the total mechanical energy consumption.
