摘要
深松是保护性耕作的重要组成部分,通过深松能改善土壤的透水、透气性能和团粒结构,从而有利于作物根系的发育。目前,深松的方式主要为深松铲式深松,存在着深松效果差、影响范围小等问题,研究新的深松方式是行业发展的必要趋势。该文总结传统深松技术的现状和特点,通过分析国内外高压气体在提高土体渗透性方面的应用及气压深松技术的研究现状,提出了气压深松技术的发展趋势,为气压深松机械及装备的研制提供了参考依据。
Subsoiling is an important part of conservation tillage, which has advantages for the growth of crop root by improving the water and air permeability and crumb structure of soil. The existing method of subsoiling is deep shovel subsoiling, which has prob- lems of poor effect and small influence area, thus, studying the new subsoiling method is necessary. Present situation and characteris- tics of traditional subsoiling technology are summarized in this paper, and then, the application of high pressure gas in improving soil permeability and research status of pneumatic subsoiling technology are analyzed, and development trend of pneumatic subsoiling tech- nology is expounded. The whole study provides a reference for the development of pneumatic subsoiling machinery and equipments.
