Abstract: In order to improve the farmland soil structure, productivity and soil moisture conservation ability in Beijing, we have carried out this project since 2011 in conservation tillage farmland to study the effect of subsoiling. The test plots are in Beijing yanqing, and arranged a test by one factor three level test.the subsoiling rotary tillage, subsoiling subsoiling and rotary tillage and harrow and traditional (control) analysis of 3 kinds of performance characteristics and yield of spring maize growth of tillage field contrast, to investigate the effect of different tillage patterns, determine the optimal cropping pattern. The results showed that subsoiling and rotary tillage treatment, 11155.5 kg/hm2; deep tillage and harrow, 10872 kg/hm2; the control of rotary, 9985.5 kg/hm2. Deep tillage + rotary tillage and subsoiling + rake two treatments compared with the traditional rotary had significantly difference per 0.0667 hectares yield.
