项目摘要

The situation surrounding paddy field agriculture in Japan is very severe, and reduction in production cost is required. The aims of largescale land consoridation project are to increase labor productivity. The project in Kawasaki Village was investigated as a model case. Farm block of 250m by 300m is made level. Sub-irrugation is schemed to make direct seeding on dried field possible.A farm management association has been established and half the farmers entrust their farm land to the association. This association payment of land to the farmers. Direct seeding culture on ponding or dried field is considered in this project area because of its high labor productivity. From field investigation and laboratory test, the permeability of constructed foundation revealed to be rather small. The development of cracks in subsoil is essential to high labor productivity or mulitipurpose use of paddy field.The objective area of large -scale land consolidation project is estimated to be 150-200 thousand ha at the present, considering topographical condition, request by farmers and potentiaities of repayment by farmers. Large-scale mechanized (65 HP tractor etc.) farming system can be practical in large-scale field lots in Japan.

日本稻田农业的形势非常严峻，需要降低生产成本。大规模土地联合项目的目的是提高劳动生产率。川崎村的项目作为一个典型案例进行了调查。250 m × 300 m的农场块是水平的。为了使旱地直播成为可能，计划进行地下灌溉，并成立了农场管理协会，一半的农民将他们的农场委托给协会。这个协会把土地付给农民.本项目区考虑采用积水或旱田直播栽培，劳动生产率高。现场调查和室内试验表明，已建地基的渗透性较小。水稻土底土裂缝的发育是提高劳动生产率或实现水田多用途的必要条件，考虑地形条件、农民要求和农民偿还潜力，目前大规模土地整理工程的目标面积预计为15 ~ 20万hm ~ 2。大型机械化（65马力拖拉机等）耕作制度在日本的大规模田块中是可行的。
