履带式窄幅小微型深松机试验

近年来，土地深松作为一种保护性耕作在全国范围内大规模推广应用。针对受地形所限和农艺所限，常规拖拉机去不了的坡地、茶园和温室大棚等立地条件，先后对履带式窄幅小微型深松机的动力、行走机构和深松铲等关键部分进行多次试验，探索出一种采用7.35 kW微型柴油机、橡胶履带行走机构带动小型深松铲进行深松作业的新模式。经田间试验，其深松深度合格率、邻接行距合格率和漏耕3项作业指标满足深松作业质量有关行业标准。为后续进一步开展履带式窄幅小微型深松机研究，推进丘陵山区、茶园和温室大棚等深松作业提供了重要参考。 

Experimental Study on Crawler Type Narrow Width Mini Deep Loosening Machine

In recent years，subsoiling as conservation tillage has been widely applied throughout the country. In view of the site conditions such as slopes，tea gardens and greenhouses that conventional tractors can not go to due to the limitation of terrain and agronomy，several experiments had been carried out on the power，walking mechanism and subsoiling shovel of the narrow mini loosening machine，and a new mode of subsoiling operation with 7.35 kW miniature diesel engine and rubber track walking mechanism had been explored. Field experiments showed that qualified rate of subsoiling depth，qualified rate of adjacent row spacing and lost tillage met relevant industry standards of subsoiling operation quality. It provides an important reference for further research on narrow width mini loosening machine and promoting deep loosening operation in hilly and mountainous areas，tea gardens and greenhouses.
