Abstract: Ditching and fertilization are important link in orchard management． In view of dense distribution of fruit trees and uneven terrain in orchards in hilly areas of Zhejiang Province, a crawler offset ditching fertilizer applicator with compact structure, good climbing performance and ditching depth adjustment device has been developed． Test results showed that depth of trenching was 0～300 mm, fertilization efficiency was 0～6 L/m, and no-load climbing angle was 22°, which basically met operation requirements of close distance fertilization for fruit trees in gentle slope orchards．
