摘要
试验重点考察低温季节时,再力花人工浮床系统,在收割和不收割不同情况下,对水体的营养盐降解和植物组织衰亡向水体释放营养物质的相互影响。结果表明,浮床收割后植株根系安全越冬率仅50%,向水体释放了更多的营养物质。
The mutual influence between the nutrient degradation of artificial floating bed of thalia dealbata under different conditions of harvest or not and the nutrient release by plant decay in the low temperature season was discussed.The results show that the survival rate of plant roots is only 50% after harvest,and more nutrition is released into water body.
