主要从土壤、水环境和杂草防控三个方面,对目前我国稻蟹共作模式下田间生态的研究现状进行了总结与分析.提出了几种目前比较常见的稻蟹共作模式,即有机稻蟹和常规稻蟹两种普遍模式.分析了稻蟹共作对土壤理化性质、土壤酶活性和根际微生物区系的影响.养蟹稻田可以显著降低土壤容重,而总孔隙度及全氮、全磷、碱解氮、有效磷、速效钾和土壤有机质含量都显著增加;显著提高0～10 cm土壤脲酶、蛋白酶、脱氢酶以及过氧化氢酶的活性;土壤根际微生物以细菌为主要菌群,氨化细菌、反硝化细菌、嫌气性纤维素分解菌、好气性自生固氮菌、亚硝酸细菌数量显著高于单作水稻;与常规稻蟹相比,有机稻蟹的土壤性状表现...

The research status of field ecology under rice - crab co-cultivation mode in China was summarized and analyzed from three aspects: soil, water environment and weed control. Several common modes of rice - crab co-cultivation. namely organic rice - crab and conventional rice - crab,were put forward.The effects of rice - crab co-cultivation on soil physical and chemical properties, soil enzyme activities and rhizosphere microflora were analyzed. The results showed that;Crab paddy could significantly reduce soil bulk density,while it could significantly increase total porosity and total nitrogen ...
