Effects of Rice-loach Symbiosis Ecosystems on Rice Quality and Economic Benefit

研究了在湖南浏阳生态条件下稻田养鳅模式对稻米品质和经济效益的影响。结果表明,该种养模式能显著降低垩白粒率、垩白度,有利于稻米外观品质的改善;提高了蒸煮及营养品质中的碱消值,降低了稻米蛋白含量。在经济效益方面,稻田养鳅模式的产投比明显高于水稻单一种植,两年平均利润19 573元/hm2,远高于单一水稻种植的1 464.5元/hm2。因此,稻田养鳅模式在一定程度上既能改善稻米品质又能提高经济效益,为稻田生态种养耦合技术提供了一种新的技术途径。

The effects of rice-loach symbiosis ecosystem on rice quality and economic benefits were studied in Liuyang, Hunan Province. The results showed that： rice-loach symbiosis ecosystem could significantly reduce the chalky rice rate and chalkiness, and improved rice appearance quality, increased the alkali spreading value to some extent, and reduced rice protein content, but with no significant difference. For the economic benefits, the ratio of output to input was obviously higher in the rice-loach ridge cultivation mode than the mono-rice cultivation, with an income of 19573 Yuan per hectare on average. In conclusion, the water-saving rice-loach cultivation mode could improve rice quality and increase economic benefit, providing a new way for the ecological cultivation of rice.
