微藻具有生物量大、生长周期短以及易于培养等优点。为了了解其在液体肥方面的应用潜力,研究了蛋白核小球藻、四尾栅藻和卷曲鱼腥藻提取液浸种对黄瓜和番茄种子萌发的影响。结果表明,不同浓度3种微藻提取液浸种对黄瓜和番茄种子的发芽势和发芽率没有明显影响;对黄瓜和番茄苗的根长、须根数、根干质量、茎长、茎叶干质量均有不同程度的促进作用,但提取液浓度过大或过小,效果均不理想,只有合适的浓度才有促进作用。
Microalgae with biomass, short growth cycle and easy to culture and so on. In order to understand its application potential in liquid fertilizer, the effects of soaking Chlorella pyrenoidosa and Scylla serrata extract on the germination of cucumber and tomato seeds were studied. The results showed that the soaking of three microalgae extracts at different concentrations had no significant effect on the germination potential and germination rate of cucumber and tomato seeds. The root length, number of fibrous roots, root dry weight, stem length, dry weight of stems and leaves Have different degrees of promotion, but the extract concentration is too large or too small, the effect is not ideal, only the appropriate concentration can promote.
