| 中文摘要: |
| 旱作区耕地的“犁底层”已成为农业耕作的一大障碍。介绍了机械深松营造“土壤水库”工程技术及推广研究中采用的方法和主要技术措施;综述了在兰州地区推广应用情况及对比试验结果;并分析探讨机械深松营造“土壤水库”工程技术的增产机理。经过分析认为,该技术是旱作区农业增效农民增收的有效途径,推广前景十分广阔。 |
| 英文摘要: |
| The “plow pan” on the farmlands in dry-farming areas is a serious problem to the agricultural production. In this paper, the engineering technique of constructing “soil reservoir” by mechanical subsoiling and its main technical measures is introduced, and its extension situation and experiment results in Lanzhou region are summarized. By analyzing the contrast results, the yield increase mechanism of this technique is given. It is shown that this technique is available to increase efficiency and income in dry-farming areas and is worthy of extending widely. |
