摘要: 为了改善北京地区农田土壤结构、提高土壤蓄水保墒能力,提升农田生产能力,增加作物产量,本项目自2011年开始在北京市延庆县保护性耕作试验田开展农田深松效果研究,该文通过单因素三水平的试验方法安排试验,通过对深松加旋耕、深松加耙和传统旋耕(对照)3种耕作模式下春玉米田间生长特性及产量表现的对比分析,探讨不同耕作模式的效果,确定最佳的耕作模式。结果表明,深松加旋耕处理产量为11155.5 kg/hm2,深松加耙处理产量为10872 kg/hm2,对照旋耕产量为9985.5 kg/hm2。深松加旋耕和深松加耙处理较对照传统旋耕公顷产量有明显差异。

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.
