Mechanical Working Technology for Vegetables Cultivation in an Upland Field Converted from a Heavy Clay Paddy (Part 2)

Farm Work Labor-saving Using the Multiple Management Vehicle

Abstract

This study investigated uplandization and mechanical working technology for an upland field converted from a heavy clay paddy. Consistent power farming systems of green soybeans, Welsh onions, and cabbages functioned easily because of the good physical conditions of soil in this upland field. It increased the productivity and seeding accuracy for the consistent power forming systems of green soybeans to use a fertilizer drill and a simple trencher. In cultivation of Welsh onion, we were able to use the multiple management vehicle for earthing up and pest control, but we could not use the vehicle for the latter half of cultivation because of the height clearance limitation. The cultivation of cabbage using a fertilizer ridger and auto-transplanter increased the productivity rate. A W type nozzle that was put on the boom sprayer increased the acaricide deposition index and mite moratality of the latter half of cabbage cultivation. The coverage of power forming systems that used the multiple management vehicle was 19.1 ha for green soybeans, and 4.1 ha for cabbage.
