Evaluation of Econmical signification to introduce Italian rice directseeding technology in Japan rice production

在意大利，平均稻田管理面积为43公顷，稻米产量可达65日元/公斤。意大利的农场经理可以通过使用激光激光平整而不是土壤淤泥来获得水平田地，从而获得很大的收益。在意大利，农地所有权改革在第二次世界大战后没有发生。正是由于这两个原因，意大利才有了规模化和节约化的发展。在没有规模化农业的情况下，意大利的种子成本、化肥成本和机械成本都低于日本。高密度直播和低人工的春季管理是低成本生产的因素，但意大利种植的品种在高密度播种环境下具有很强的抗倒伏能力。

In Italy average rice farm management have areas of 43ha can produce rice by 65 yen/kg. Italian farm managers can get big percels by using laser lazerleveling instead of soil puddling to get horizontal fields. And in Italia farmland ownership reformation did'nt happen after Second World War. Large scale farming and labor-saving are advanced in Italia by these two reasons.Without large scale farming,Italian seed cost,fertilizer cost and machine cost are lower than Japanese ones. Directseeding by much density seeding and low labour springtime management are factors of low cost production.However varieties grown in Italia have strong lodging resistance in much density seeding circumstances.
