1 池塘的基本条件 1.1 池塘的选择:应选择在河网地区或光照、水源条件好的地方。受工业废水影响,温度过低、含硫量过高的水源,不利于河蟹生长,应尽量避开类似地方。 1.2 池塘面积、水深:池塘生态环境受外界影响较为明显,应选择较大面积的池塘,但受小面积不得低于0.67hm~2,且必须水源条件好,有利于水质调控。池塘深度1.5～2.0m,水深通常保持1m左右。4～5月和9～10月水深调整在0.5～0.8m,6～8月水深调整为1.0～1.2m左右。冬放蟹种池水深度应保持在1.2m。
1 The basic conditions of the pond 1.1 The choice of ponds: should be selected in the river area or light, good water conditions. Affected by industrial wastewater, the temperature is too low, high sulfur content of water is not conducive to the growth of crabs, should be avoided in similar places. 1.2 pond area, water depth: the pond ecological environment is more obvious by the outside world, should choose a larger area of the pond, but the small area of not less than 0.67hm ~ 2, and must be good water conditions conducive to water quality control. Pond depth of 1.5 ~ 2.0m, water depth usually maintain 1m or so. From April to May and from September to October, the water depth was adjusted from 0.5 to 0.8m, and from June to August, the water depth was adjusted to about 1.0 to 1.2m. The winter crab water depth should be maintained at 1.2m.
