对重庆市中低产田土深度开发模式进行了研究，结果表明，重庆市中低产田综合开发利用有5大结构类型，22种模式。水稻产量以稻-稻+鱼模式最高，平均产量10275 kg/hm2，比冬水田-稻模式增产23.87%; 其次是稻-稻+鱼+笋和稻-稻-菜模式。经济收入以草莓+葡萄+菜模式最佳，产值99405元/hm2，盈利72300元/hm2，分别是冬水田-稻模式的8.3倍和9.6倍。稻田实行深度开发利用的光能利用率比常规种植模式提高了17.3%～94.5%。由此表明, 中低产田深度开发具有良好的经济效益和生态效益。
The results show that there are five major types and 22 modes of comprehensive development and utilization of medium and low yield farmland in Chongqing. The rice yield was highest in the rice-rice + fish model, with an average yield of 10275 kg / hm2, which was 23.87% more than that in the winter paddy-rice model. The rice-rice + fish + bamboo shoots and rice-rice-vegetable model were followed. The economic income is the best in strawberry + grape + vegetable pattern with the output value of 99,405 yuan / hm2 and the profit of 72,300 yuan / hm2, respectively, which are 8.3 times and 9.6 times that of winter paddy field-rice pattern respectively. The utilization of light energy for deep development and utilization of paddy fields has increased by 17.3% ~ 94.5% compared with the conventional planting mode. This shows that the depth of middle and low yield field development has good economic and ecological benefits.
