针对洞庭湖区低洼湖田地势低洼,只能种植一季水稻,土地利用率不高的情况,通过改造低洼湖田,研究了稻虾共作的生态种养模式及效益.结果表明：低洼田一季稻的利润约为 575 元 /667m^2,稻虾共作试验田利润约为 1 661 元 /667m^2;稻虾共作使大部分低洼荒废湖田得到充分利用,防灾减灾、生态效果明显,不仅提高了粮食安全水平,还增加了单位面积产值,单位利润是-季稻利润的2.9 倍.稻虾共作模式是一种互惠互利的立体循环农业,适合在洞庭湖区推广.

The land utilization rate is very low with low-lying, and only planting one season rice in low-lying field of Dongting Lake. The rice-shrimp ecological planting and breeding mode and its benefit were studied by transforming low-lying lake field. The results showed that the average profit of rice in low-lying farmland was about 8625 Yuan/hm2(RMB), and the average of rice shrimp was about 24915 Yuan/hm2(RMB).The rice-shrimp ecological planting and breeding mode can make full use of most of the low-lying abandoned field, prevent and mitigate disaster, improve ecological effect and the level of fo...
