中文摘要：为探明稻蛙种养对稻田主要土壤酶活性及养分含量的影响,本研究测定了稻田中套养虎纹蛙后不同种养殖时期稻田土壤酶活性及主要养分(N、P和K)含量的变化,并以施用化肥的稻田为对照。结果表明,在虎纹蛙养殖10~90 d内,试验田的过氧化氢酶活性持续下降,而脲酶、酸性磷酸酶和中性磷酸酶活性均持续增加;对照田的过氧化氢酶活性则呈先上升后下降的趋势,而脲酶活性不断下降;在试验田和对照田中,转化酶均呈先升后降的趋势,脱氢酶活性均持续增加;碱性磷酸酶活性均持续下降。在虎纹蛙养殖前10 d到养殖后60 d,试验田与对照田的碱性磷酸酶活性均呈下降的趋势,且两者间无显著性差异(P>0.05),只有在养殖90 d后,试验田的碱性磷酸酶活性明显增加且显著高于对照田(P<0.05);在虎纹蛙养殖10~60 d内,试验田的总N、P和K含量均显著低于对照田(P<0.05),90 d后才显著高于对照田(P<0.05);同时,在虎纹蛙养殖前60 d,试验田的多种土壤酶活性和主要养分含量均显著低于对照田(P<0.05)。由此可知,只有在虎纹蛙养殖90 d后,随着蛙粪积累增多,土壤酶活性和主要养分才得到显著提高,增加了试验田养分的供给。本研究结果为稻蛙种养的养分管理提供了新的理论指导。

外文摘要：To investigate influence of rice and frogs planting on enzymatic activities and main nutrient contents（N,P and K） in paddy field,rice variety of Jiahe 218 and frog of Hoplobatrachus chinensis were employed in this study.Related enzymatic activities and contents of N,P and K were measured at interval during planting process. The field treated with chemical fertilizers was used as control. Results showed that,during frog culture of 10 to 90 days,catalase activity in treated field reduced continuously,while in control field catalase activity increased initially and then decreased afterward. Meanwhile,activities of urease,acid phosphatase and neutral phosphatase in activity of treated field increased gradually but urease activity in control field decreased continually. However,invertase activity in both fields increased at initial stage and then decreased. A continuous increase in activity of dehydrogenase and decrease in activity of alkaline phosphatase was observed in both groups. There was no instinct difference for alkaline phosphatase activity in treated and control field（P 〉0. 05） during 10 ~ 60 days. In addition,after 90 days plants,alkaline phosphatase activities in treated field increased significantly and were much higher（P 〈0. 05） than those in control group. Total N,total P and total K contents in treated field were significant（P 〈0. 05） lower than those in control group at 10 ~ 60 days,but obviously higher than those in control at 90 days. Activities of many related enzymes and contents of total soluble N,P and K in treated field were significant（P 〈0. 05） lower than those in the control group at10 ~ 60 days. Our results indicated that,after 90 days plantings of rice and frogs,enzymatic activities and total nutrient contents were increased with the accumulation of frog manure. In conclusion,this study provides a new theoretical guidance for nutrient management of rice and frog eco-planting in paddy field.
