稻田养蟹“盘山模式”的水温特征分析

Characteristics of Water-temperature of Rice Field Crab "Panshan mode"

[目的]研究稻田养蟹"盘山模式"的水温特征。[方法]利用稻田养蟹"盘山模式"中水田温度和气象监测资料,分析了该模式中不同深度的水温随天气变化的特征,同时结合试验基地2009年的河蟹和水稻的生产效益,讨论了水温变化给河蟹生态养殖带来的效益。[结果]盘山稻田养蟹模式无论在晴天或雨天均能够在一定程度上很好地改良河蟹最重要的生存环境因子之一——水温,扩大了河蟹生存活动的垂直空间。[结论]为实现水稻增产、河蟹养成规格增大提供保障。

[Objective]The aim was to study characteristics of water-temperature of rice field crab ＂panshan mode＂.[Method] temperature of the paddy fields and meteorological monitoring data in rice crab ＂ Panshan mode ＂ were used as materials,water-temperature characteristics at different depths with changes in weather were analyzed,combined with the productivity of crab and rice in test base in 2009,the benefits of ecological culture of crab caused by temperature change were discussed.[Result] The most important environmental factor-water temperature was good improved by ＂Panshan mode＂ in some degree whether in rainny or sunny days. The vertical space of crab survival activities was expanded.[Conclusion]The study provided a guarantee for increasing production of rice and crab size.
