摘 要:针对目前浙中地区甘蔗种植中耕施肥起垄培土农艺特点要求,V型深沟甘蔗中耕管理机工作部件具有较好的入土、碎土、抛土和清沟的能力,能形成较好的V型沟横截面。本文通过对浙中地区甘蔗种植的窄行距的农艺要求分析,研究设计了整机和V型深沟起垄刀盘、清沟拍打机构等关键部件。田间试验结果表明:管理机作业效率可达0.19 hm^2/h,开沟深度平均可达230 mm,培土厚度可达70 mm,开沟深度稳定系数可达85%,碎土率可达95%;排肥器对颗粒肥具有较好的排肥效果,未见甘蔗苗有明显的伤苗和烧苗现象,达到了设计要求。According to the agricultural characteristics of sugarcane planting in central Zhejiang Province, i.e. intertilling, fertilizing, ridging and earthing-up, the V-shaped deep trench sugarcane cultivator is equipped with good working parts, such as soil digging, breaking, casting and trench clearing. It can form a good V-shaped groove cross section. This paper analyzed the agronomic requirements of sugarcane planting in central Zhejiang Province and narrow row spacing, designing the key parts of the whole machine, such as V-shaped deep trench ridging cutter plate, trench clearing, etc. Field experiment results showed that the efficiency of the management machine could reach 0.19 hm2/h. The trench depth and the thickness of soil could reach 230 mm on average and 70 mm, respectively. The trench depth stability coefficient reached about 85%. The soil breaking rate reached about 95%. The fertilizer distributor had a good effect on granular fertilizer. No obvious damage and seedling emergence were found in sugarcane seedlings. The design of the machine meets the agronomic requirements of sugarcane planting in central Zhejiang Province.
