摘要
通过模拟试验,研究了4种不同比例的基质(沙土∶黄土∶淤泥=1∶1∶8,沙土∶黄土∶淤泥=1∶1∶3,沙土∶黄土∶淤泥=1∶1∶1,沙土∶黄土∶淤泥=5∶1∶1)对穗花狐尾藻、轮叶黑藻生长的影响。结果表明,生长在4种不同比例基质下的穗花狐尾藻和轮叶黑藻,其最终生物量、最大株高及分蘖数以沙土∶黄土∶淤泥=1∶1∶8基质条件下最佳,生长状况以相对贫瘠的沙土∶黄土∶淤泥=5∶1∶1基质条件下最差。叶绿素的测定结果进一步证明了以上结论。
Four different sediments ( sand: loess: sih = 1 : 1: 8, sand: loess: silt = 1: 1 : 3, sand: loess: silt = 1 : 1 : 1, sand: loess: silt = 5 : 1 : 1 ) were investigated through simulation experiments in laboratory on their effects on the growth of Myriophyllum spicatum L. and Hydrilla verticil- lata. The results showed that the best sediment of final biomass, maximum height and tamers of Myriophyllum spicatum L. and Hydrilla verti- cillata grown in four different sediments was sand: loess: silt = 1: 1: 8, the worst sediment was sand: loess: silt =5: 1: 1. The measurement re- sults of chlorophyll were further evidence above conclusion.
