摘要
吉林省西部苏打型盐碱苇塘鱼、蟹养殖试验结果表明:鱼、蟹年平均产量为1 425.9 kg·hm-2和123.9 kg·hm-2,年平均经济效益1.591万元·hm-2,投入产出比平均为1.001.95;土壤含盐量年平均下降26.17%,土壤有机质含量年平均增加12.07%,全氮、全磷和全钾的含量平均提高55.06%、25.99%和29.86%;芦苇地表生物量年平均提高9.71%。该模式可在吉林省西部中低产苇塘的开发利用中推广应用。
Experiment results of fishes and crab in soda saline reed ponds in west Jilin province indicated that annual aver -age production of fishes and crab was 1 425.9 kg · hm-2 and 123.9 kg · hm-2 , annual average economic benefit was 1.591million· hm-2 , average output-input ratio was 1.00:1.95;annual average soil salinity declined 26.17%;annual average content of soil organic matter incrfeased by 12.07%, average content of total nitrogen , total phosphorus and total potassium increased by 55.06%,25.99%and 29.86%, respectively,annual average surface biomass of reed increased by 9.71%.The model could be popularize and apply in the development and utilization of middle and low yield reed ponds in west Jilin province.
