苏打型盐碱化芦苇沼泽地“苇-蟹-鳜-鲴”模式研究
An eco-agriculture model of "reed-crab-mandarin fish-microlepido yellowtal"for enhanced production functions of soda saline-alkali reed marshlands
摘要
Abstract
To explore high beneficial use of soda saline-alkali reed marshlands,an eco-agriculture model (consisting of reeds,crabs,spotted mandarin fish,and microlepido yellowtail) was developed and tested in a 23.6 hm2 marshland.The model tamed and cultured crabs,spotted mandarin fish and microlepido yellowtal in saline-alkali water with natural food supply.The model also involved farmland water conservancy projects,water quantity and quality management and reeds high-output cultivation.The results for 2006-2009 showed that the outputs of crabs,spotted mandarin fish and microlepido yellowtal were 81.00 kg·hm-2,39.34 kg·hm-2 and 58.62 kghm-2,respectively.Reed output was 5 478 kg·hm-2,which represented an increase of 1.2 times (22.0% per year) over natural marshlands.The total economic benefit from the model was 1.45×104 Yuan per hm2,an increase of 13 times over naturalmarshlands.Water salinity,alkalinity and soil salt content respectively declined by 19.1%,10.3% and 20.3%.Soil organic matter content also increased by 8.9% per year.The model increased per-capita net income by 11.2% per year,which represented a contribution rate of 43% to increase of per-capita net income.The findings suggested that the model application further enhanced the functions of production and ecology of soda saline-alkali reed marshlands.The model achieved simultaneous benefits for the economy,ecology and society,and was therefore applicable to soda saline-alkali reed marshlands.关键词
