本论文对盐藻培养过程中敌害生物的防治、不同培养条件(营养盐浓度、光周期)对盐藻生长及代谢产物(多糖、β-胡萝卜素、多不饱和脂肪酸)积累的影响、航天搭载后盐藻代谢产物积累的变化等方面进行了研究,得出结论如下: 1。
3) periphyton

Effect of periphyton on the growth of Elodea nuttalii;
附着生物对沉水植物伊乐藻生长的研究
2.
5:1 and 50:1,respectively,while the growth of periphyton,especially of epiphytic algae,was the worst,giving the least adverse effects on V.
5:1和50:1时的54%和31%;当TN/TP为25:1时,附着生物尤其是附着藻类的生长状态最差,对苦草生长的不利影响最小;可见,富营养水体中适宜于苦草生长的TN/TP为25:1;TN/TP为25:1这一比例的应用具有相对性,当水体营养浓度低于限制水平时,该比例适用,如果水体中营养盐浓度超过限制水平时,该比例则不适用。
