摘要： 为探究小球藻作为液体肥料对植物生长的促进作用，以小球藻为研究对象分别进行水培实验与土培实验。水培实验结果表明，施用0.05 g/L小球藻NCU-2对铜钱草和绿萝的生长均有一定促进作用，与清水相比，铜钱草叶片数量增加60%以上，总叶面积增幅达84.63%~367.08%，同时使绿萝茎长增长67.78%以上，总叶面积增幅达70.92%~123.70%；土培实验结果表明，施用0.04 g小球藻NCU-2对辣椒的生长也具有一定促进作用，与清水相比，辣椒株高增长10%以上，果实数量增长48.48%~112.12%。施加小球藻NCU-2后，土壤中速效钾、有机质含量均上升，增幅在11.30%~20.04%。实验结果显示小球藻NCU-2藻液不仅能够促进这种植物生长，还在一定程度上改善了土壤理化性质，这对进一步探究小球藻对植物的促生长作用以及实际应用有一定的参考意义。

Abstract: To explore the promoting effect of Chlorella as liquid fertilizer on plant growth, Chlorella were investigated as liquid fertilizer in water culture experiment and soil culture experiment respectively. The results of water culture experiments showed that application of 0.05 g/L Chlorella NCU-2 could promote the growth of Hydrocotyle verticillata and Epipremnum aureum. Compared with that of the water control, the number of leaves increased by more than 60% and the total leaf area increased by 84.63%-367.08% on Hydrocotyle verticillata. Meanwhile, the stem length increased by more than 67.78%, and the total leaf area increased by 70.92%-123.70% on Epipremnum aureum. The results of soil culture experiments showed that application of 0.04 g Chlorella NCU-2 could promote the growth of Capsicum annuum Linn. Compared with that of the water control, the plant height and the fruit number of Capsicum annuum Linn increased by 10%, 48.48%-112.12%, respectively. After the application of Chlorella NCU-2, the contents of available potassium and organic matter in the soil increased by 11.30%-20.04%. The results implied that Chlorella NCU-2 could not only promote the growth of three plants, but also improve the soil physicochemical properties, which had a certain reference significance for further exploring the growth promoting effect of Chlorella on plants and practical application.
