The Influence of No-tillage and Detective Soil Moisture on Soil Surroundings and Maize Yield in Dryland

The test results of dryland maize cultivation under different tillage methods show that the soil bulk density in the depth of 2 cm～7 cm under no-tillage and detective soil moisture was increased by 4.31% comparing with rotary tillage,didn't reach significant level; no-tillage and detective soil moisture could reduce the soil temperature,and improve the soil moisture content in the depth of 0 cm～20 cm; the maize yield under no-tillage and detective soil moisture was 6 591.82 kg/hm2,and was lower 553.36 kg/hm2than rotary tillage, and the reduction effect didn't reach significant level. These results show that the no-tillage and detective soil moisture was an effective drought resistance sowing method in dryland agriculture.
