| 采用单因子设计，研究水温、光照和pH对阿根廷蜈蚣草顶枝净产氧量和毛产氧量的影响。结果显示：（1）水温10～35℃时，水温与阿根廷蜈蚣草净产氧量和毛产氧量的值均呈曲线形相关，阿根廷蜈蚣草的适宜生长温度为20～30℃；（2）在（0．03～6．04）×10^4lx的照度范围内，光照强度与净产氧量和毛产氧量均呈曲线型相关，当照度为4．82×10^4lx时，阿根廷蜈蚣草的产氧能力最强；（3）pH为5—11时，阿根廷蜈蚣草顶枝的净产氧量、毛产氧量与pH均呈线性负相关，表明阿根廷蜈蚣草生长喜欢中性偏酸的环境。 |

| The single-factor design was adopted to investigate the effects of water temperature, light intensity and pH on net and gross oxygen production of telomes of Egeria densa. The results showed that ： （ 1 ） Net and gross oxygen production showed a relationship of convex curve with temperature in the range of 10℃ - 35℃ and indicated the preferential temperature for Egeria densa growth are between 20℃ to 30℃ ; （2） Net and gross oxygen production showed a convex curvilinear correlation with light intensity in the range of 0.03×10^4 lx -6.04 ×10^4 lx and the highest production appeared on 4.82×10^4 lx ; （3） When pH was in the range of 5 - 11, net and gross oxygen production of Egeria densa was in a negative linear correlation with pH, suggesting that the plant is slightly acidophilous. |
