摘 要:京郊地区甘薯种植中耕环节一直以人工除草为主,为解决人工作业强度大、效率低和成本高的问题,结合北京市密云区甘薯种植模式及农艺要求,开展2TD-S2型中耕除草机作业性能试验。结果表明,此台甘薯中耕除草机可一次性实现垄沟除草、覆土等作业,采用悬挂式作业,能够有效解决田间管理过程中土垄塌陷的问题。在甘薯缓苗期垄沟及垄坡面高度10 cm以内杂草除净率可达80%。若遇草害严重,可多次进行中耕作业以达到灭除草害的作用,该机劳动生产率较人工移栽有大幅度提高,且生产作业成本较低,适宜在京郊进行薯苗移栽作业,可以在实际生产中推广应用。In order to solve problems of high intensity,low efficiency and high cost of manual work,cultivation of sweet potato in Miyun district had been dominated by manual weeding,experiment of 2 TD-S2 cultivator was carried out. Results showed that this sweet potato cultivator could eliminate weeds and cover soil in furrow in one time,and it could effectively solve problem of soil ridge collapse in field management. 80% of weeds could be removed in the gentle seedling stage of sweet potato within 10 cm of ridge and slope height. If grass damage was serious,it could be used for many times in intertillage to eliminate weed damage. Labor productivity of this machine had been greatly increased compared with manual transplanting,and production cost was lower. This machine was suitable for transplanting potato seedlings in the suburbs of Beijing,the utility model could be popularized and applied in practical production.
