天津沿海碱荒地带 ,自明清以来农业垦殖发展较快 ,逐步成为华北主要水稻产区。华北事变以后 ,日本为掠夺稻米、棉花等农产物 ,投资组设农场 ,强征当地土地、劳力 ,进行殖民土地开发 ,对华北日军的军粮供应 ,发挥了较大作用。日系农场多沿用旧租佃制 ,将土地分割小块出租 ,并未带来先进耕作方式 ,耕作者负担也比战前大大加重。日系农场在 1 941年前后较为活跃 ,到战争后期 ,由于周边抗日力量的兴起 ,不断遭受打击 ,最终陷入困顿。 Since the Ming and Qing Dynasties, the agricultural reclamation has developed rapidly and gradually became the major paddy producing area in North China. After the North China Incident, Japan plundered the agricultural products such as rice and cotton and set up farms, forced the local land and labors, and exploited colonial lands. This played an important role in supplying the military supplies to the Japanese army in North China. Japanese farms and more use of the old tenancy system, the small piece of land rental, did not bring advanced farming methods, the burden on farmers than the pre-war greatly increased. Japanese farms were relatively active around 1941, and they were constantly hit by the rise of peripheral anti-Japanese forces in the late part of the war and eventually ended up in distress.
