摘要
开沟施肥作业是果园管理的重要环节,针对浙江省丘陵地区果园果树分布密集、地形不平整的情况,研制出一款结构紧凑、爬坡性能好、具备开沟深度调整装置的履带式偏置开沟施肥机。试验结果表明,开沟深度0~300 mm,施肥效率0~6 L/m,空载爬坡角度22°,基本适应缓坡果园果树近距离开沟施肥的作业要求。
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.
