【摘要】：在南美白对虾高效生态循环养殖系统净化池内,以浮岛形式种植北美海蓬子,研究了北美海蓬子生态浮岛种植技术和其生长特征,构建小型管道式无土栽培系统研究北美海蓬子对养虾废水的净化作用。结果显示:生态浮岛种植的北美海蓬子平均株高为69.5 cm,单位面积产量9.1 kg·m~(-2)(鲜重),北美海蓬子生长过程中株高株重呈指数增长关系,其函数关系式为y=0.376e~(0.110x);北美海蓬子对养虾废水中的NH_4~+-N具有优先吸收的作用,其次是NO-2-N;对于养虾废水中的无机N、无机P和TN、TP,北美海蓬子都有较好的去除效果;北美海蓬子植株体内TN和TP的含量(鲜重)分别为0.05%和0.009%,浮岛北美海蓬子可去除的TN量为4.55 g·m~(-2),TP量为0.82 g·m~(-2)。
[Abstract]:In the purifying pond of high efficiency ecological recycling culture system of Penaeus vannamei, this paper studied the planting technology and its growth characteristics of the ecological floating island of P. vannamei in the form of floating island. A small tubular soilless cultivation system was established to study the purification of shrimp culture wastewater by the North American Seaweed. The results showed that the average plant height of the North American Seafood grown on the ecological floating island was 69.5 cm, and the yield per unit area was 9.1 kg 路m ~ (-2). Plant height and plant weight increased exponentially during seed growth. The formula of the function is: 0.376eOE 0.110xC, the North American Seaweed has preferential absorption of NH4- N in shrimp culture wastewater, followed by NO-2-N, and the removal efficiency of inorganic N, inorganic P and TNT TPin in shrimp culture wastewater is better than that in North American salicillium spp, and the effect of removing NH4- N from shrimp wastewater is better than that of NO-2-N, and the effect of removal of inorganic N, inorganic P and TNTP-TPin from shrimp wastewater is better. The contents of TN and TP (fresh weight) were 0.05% and 0.009, respectively, and the removal amount of TN was 4.55 g 路m ~ (-1) 路m ~ (-2) N ~ (2 +) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ 0.82 g 路m ~ (2) ~ (2) N ~ (-1).
