Water-temperature Characteristics of Rice-field-crab "Panshan Mode"

In this paper,rice crab ＂ Panshan mode＂ in the paddy fields of temperature and meteorological monitoring data,an analysis of the model at different depths of water-temperature characteristics with changes in the weather,combined with test base in 2009 the productivity of crab and rice,to discuss the ＂ Panshan mode＂ due to a large ridge with two rows,around the ring groove of the kind of interpolation method to the temperature change caused by the benefits of ecological culture of crab：crab rice first winding mode to a certain extent,good Improved survival of crab of the most important one of environmental factors-water temperature;2 is the expansion of the vertical space crab survival activities,and ultimately increase production of rice,crab size increase the purpose of cultivation.

稻田养蟹“盘山模式”的水温特征分析

[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。
