滇池水葫芦控制性种养适宜区域选择研究Ⅰ
Study Ⅰ on Selection of Suitable Region for Controlled Planting of Eichhornia crassipes in the Dianchi Lake
摘要
Abstract
In order to screen the suitable region for the growth of hyacinth (Eichhornia crassipes) , it was planted by fence facilities at 6 experimental spots in Caohai and Waihai of the Dianchi Lake, and the comparative tests were conducted to observe their growth characteristics and absorption ability to N and P under different water conditions. The results showed that the Caohai water was calm and closed to neutral water body, and its concentrations of N and P were the highest among the six spots. In addition, in the Caohai, the accumulative biomass of hyacinth was the highest, and its absorption ability to N and P was the strongest. So the Caohai was the most suitable region for the growth of hyacinth among six experimental spots. In the water area of Longmen village, a large area of Eichhornia crassipes should be planted to produce dominant population, which could form biological competition with lots of blue -green algae enriched there. The water area of Fushan village was not suitable for the growth of Eichhornia crassipes, because the wind and storm wave could seriously hurt hyacinth plants. In Baishan bay, a certain area of grown hyacinth could reduce the wind and storm wave, so its accumulative biomass was higher and absorption ability to N and P was stronger.关键词
