Abstract:
Field experiments of 3-year were conducted in
Triticum aestivum/
Zea mays intercropping by four no-tillage treatments,including no-tillage with high stubble reaping, no-tillage with straw cover, no-tillage with straw cover+ rake the soil before sowing, conventional tillage. The effects of these no-tillage treatments on the yields of
Triticum aestivum interplanting
Zea mays, soil moisture and soil erosion by wind were studied. Results showed: 1)compared with the conventional tillage, no-tillage treatments could increase mixed yields of
Triticum aestivum and
Zea mays by 2.6%-6.6%, increase the yield of
Zea mays by 8.6%-13.2%, and decrease the yield of
Triticum aestivum by 5.2%-8.8%. 2) Under no-tillage treatments, the capacity of soil water storage in the cultivated horizon increased by 13.4%-15.9%, and the soil erosion by wind decreased by 55.6%-100.0%. It can be concluded that no-tillage treatments of
Triticum aestivum/
Zea mays intercropping performed better effects, and could apply to other regions, such as in Hexi prefectures in Gansu Province, the regions on the verge of Yellow River and the same type of regions in domestic.
