Abstract

Abstract:

The rice yield, quality and rice/crab economic output of rice monoculture mode, rice-crab co-culture mode with mature crab, rice-crab co-culture mode with juvenile crab, rice-crab co-culture ecological reduction mode with mature crab and rice-crab co-culture ecological reduction mode with juvenile crab in 2019—2021 in coastal saline-alkali rice area in Liaoning Province were studied. The results showed that there was no significant difference between theoretical yield, actual yield and processing quality of rice among different mides. Rice-crab co-culture mode could significantly improve economic benefits; ecological reduction mode could improve biodiversity and increase economic benefits. Compared with rice-crab co-culture ecological reduction mode with juvenile crab, rice-crab co-culture ecological reduction mode with mature crab had higher market stability.

Key words: rice-crab co-culture mode, ecological reduction of fertilizer and pesticide, benefit, coastal rice areas, Liaoning

摘要：

为深挖稻蟹种养模式潜力，2019—2021年在辽宁滨海盐碱稻区对水稻单一种植模式（MR）、水稻+成蟹种养模式（RC）、水稻+扣蟹种养模式（RYC）、水稻+成蟹种养生态减施模式（ORC）和水稻+扣蟹种养生态减施模式（ORYC）的水稻产量、稻米品质及稻蟹投入产出进行了试验和调查分析。结果表明，不同种养模式间水稻理论产量、实际产量及稻米加工品质差异均不显著；稻蟹种养模式显著提高经济效益；生态减施模式在提高生物多样性的同时增加经济效益；生态减施模式下成蟹种养较扣蟹种养具有更高的市场稳定性。
