为研究不同生态种养模式对双季稻土壤养分及水稻产量的影响,设置稻鸭共作、稻鱼共作、稻鳅共作3种模式,并以水稻单作模式为对照.每季选用2个水稻品种,早稻品种为常规稻中早35、杂交稻陆两优996,晚稻品种为常规稻中早39、杂交稻深优5438,通过双季稻大田试验,比较分析了不同处理间双季稻土壤养分含量、水稻生物量及产量的差异.结果表明,与水稻单作相比,稻鸭、稻鳅共作能显著提高早、晚稻成熟期土壤有机碳含量,稻鸭、稻鱼共作能显著提高晚稻成熟期的土壤碱解氮含量,稻鸭、稻鳅共作能显著提高晚稻成熟期的土壤速效磷含量;稻鱼共作能够显著提高杂交早、晚稻成熟期地上部生物量,稻鳅共作能够显著提高杂...

To study the effects of crop-animal co-cultivation modes on soil nutrients and rice yield of double-cropping rice,three modes of treatment(rice-duck,rice-fish,and rice-loach)were set up,and the monoculture mode of rice was used as the control.Two rice varieties were selected in each season,including the early rice varieties of conventional rice Zhongzao 35 and hybrid rice Luliangyou 996,and the late rice varieties of conventional rice Zhongzao 39 and hybrid rice Shenyou 5438.The effects of different treatments on soil nutrient content,rice biom...
