摘要:

本研究针对复垦稻田开展了水稻-红螯螯虾共作模式对土壤肥力和碳库的影响研究。试验分为对照组和试验组,对照组为水稻单作,试验组为水稻-红螯螯虾共作。结果显示,拔节期试验组土壤中的有机质、全氮、有效磷、速效钾和有机碳含量显著高于对照组。在水稻成熟期,试验组土壤中有机质和有机碳含量也显著提高。但是,水稻-红螯螯虾共作模式对土壤pH值影响不显著。综上所述,水稻-红螯螯虾共作模式可以显著改善复垦稻田拔节期和成熟期的土壤肥力,有助于维持碳库稳定。

Abstract:

This study investigated the impacts of the rice-red claw crayfish (Cherax quadricarinatus) co-culture system on soil fertility and carbon pool in reclaimed paddy fields. The experiment included a control group (rice monoculture) and an experimental group (rice-crayfish co-culture). Results showed that during the jointing stage, the experimental group exhibited significantly higher soil organic matter, total nitrogen, available phosphorus, available potassium, and organic carbon content compared with the control group. At the rice maturity stage, soil organic matter and organic carbon content in the experimental group also increased significantly. However, the co-culture system had no significant effect on soil pH value. In conclusion, the rice-red claw crayfish co-culture system significantly improved soil fertility during both the jointing and maturity stages in reclaimed paddy fields, contributing to the stabilization of the carbon pool.

Key words: rice-red claw crayfish co-culture, reclaimed paddy fields, soil, nutrients, carbon pool
