Development of farm work machine for shaft tillage and transplanting by aged farmer

本研究的目的是开发适合老年农民使用的农机。他们可以用农机实行轮作耕作。所研制的农机由竖耕和供苗两部分组成。苗木供应单元是利用市场上的链式盆栽播种机的部分部件制造的。种植试验是由发达的农场进行的。经过实验，成功率达到90%左右。栽植失败的因素主要是源于秧苗。建议研究更高层次的播种育苗技术，以提供更均匀的育苗。

The purpose of this research is to develop the farm work machine for aged farmer. They can practice the shaft tillage cultivation with the farm work machine. The developed farm work machine consists of two units for shaft tillage and seedling supply. The seedling supply unit is manufactured using some parts of the chain pot planter on the market. The planting test was carried out by the developed farm. As a result of the experiment, the success rate became about 90%. The factor of the planting failure originated chiefly in the seedling. Then, we suggested the higher technology of sowing and raising seedling must to be researched to supply more uniform seedling.
