中文摘要：为探明稻蛙种养对稻田土壤不同形态磷含量变化的影响,以正常施用化肥的稻田为对照,测定套养虎纹蛙后其对各个时期稻田不同形态无机磷、有效磷含量变化及水稻产量构成的影响。结果发现,在虎纹蛙养殖后10~90 d,试验田与对照田不同形态磷含量的变化趋势各有不同;其中Ca_(2)-P含量不断下降,Ca_(8)-P、Al-P、Fe-P含量则表现出先增加后下降的趋势,Ca_(10)-P和O-P含量则不断增加,有效磷的含量在试验田和对照田均出现先增加后下降的趋势。在相同种养时期内,试验田的不同形态无机磷、总无机磷和有效磷含量均显著低于对照田(P<0.05)。由此可见,试验田不施化肥仅靠套养虎纹蛙,会导致稻田不同形态无机磷含量下降,有效磷供应不足,并造成水稻有效穗数、每穗粒数和总产量降低。因此,在稻蛙种养时应补充适量的磷肥才能防止供磷不足,从而提高水稻的产量。研究结果为稻蛙种养时土壤养分管理的改善提供新的理论依据。

外文摘要：To investigate the influence of rice and frog eco-planting on different forms of phosphorus content in paddy field,the rice variety of Jiahe 218 and frogs of Hoplobatrachus chinensis were used in this study.Distinct types of inorganic phosphorus,available phosphorus contents and the composition of rice yield were measured at intervals during the planting process,and the field treated with chemical fertilizers was used as a control.Results showed that,during 10 to 90 d of frog culture planting,different change trends in different forms of phosphorus contents were shown in the experimental field and control field.Ca_(2)-P content reduced continuously in both fields,however,the contents of Ca_(8)-P,Al-P,and Fe-P in both fields increased at the initial stage and then decreased.Continuous increases in the contents of Ca_(10)-P and O-P were observed in both fields.However,the contents of all types of inorganic phosphorus,total inorganic phosphorus and available phosphorus in the treated field were significantly lower than those in the control field(P<0.05).Thus,the results indicated that,after 90 d of eco-plantings of rice and frogs,the contents of different type inorganic phosphorus and total inorganic phosphorus were all decreased.For preventing phosphorus deficiency in rice and frog eco-planting field,it needs to replenish the specific amount and proportion of P fertilizer.The results of this study provided new theoretical guidance for nutrient management of rice and frog eco-planting in the paddy field.
