有機栽培水田のためのガス抜き・抑草システムに関する研究

Abstract

We proposed a mechanical system capable of continuing degassing and weeding with the aim of increasing the yield of organic cultivated paddy fields. The prototyped machine is compact sized and is a long stick into the ground while floating in water. The performance of the prototype was investigated the experiments in actual paddy fields. As the results, it showed sufficient weed suppression performance, but, the yield did not increase through indirect proof of the gas.
