海藻提取液对黄瓜·番茄种子萌发和幼苗生长的影响

Effects of Seaweed Extract on Seed Germination and Seedling Growth of Cucumber(Cucumis sativus) and Tomato(Solanum lycopersicum)

[目的]研究海藻发酵液和海藻碱提液对种子萌发和幼苗生长的影响。[方法]通过不同浓度的海藻发酵液和海藻碱提液对黄瓜和番茄种子的浸种试验,研究2种海藻提取液对黄瓜和番茄种子萌发的影响;通过不同浓度的海藻发酵液和海藻碱提液对黄瓜和番茄幼苗的水培试验,研究2种海藻提取液对黄瓜和番茄幼苗生长的影响。[结果]浸种试验结果显示:与对照组相比,海藻发酵液100倍处理组能显著提高番茄种子的发芽率和发芽势,海藻发酵液200倍处理组能显著提高黄瓜种子的发芽率和发芽势;海藻碱提液200倍和400倍处理组能显著提高黄瓜种子的发芽率和发芽势,海藻碱提液400倍处理组能显著提高番茄种子的发芽率和发芽势。水培试验结果显示:与对照组相比,海藻发酵液100倍和200倍处理组能显著增加黄瓜和番茄幼苗的根长、苗长、鲜质量、干质量、茎粗;海藻碱提液400倍处理组能显著增加黄瓜和番茄幼苗的根长、苗长、鲜质量、干质量、茎粗、根冠比。[结论]海藻发酵液和海藻碱提液均能促进黄瓜、番茄种子萌发和幼苗生长。

[ Objective ] To study the effects of seaweed fermentation extract and seaweed alkali extract on the seed germination and seedling growth of cucumber and tomato. [ Method] Taking cucumber and tomato as research objects to study the effects of different concentrations of seaweed fermentation extract and seaweed alkali extract on seed germination rate by seed soaking experiment. Taking cucumber and tomato as re- search objects to study the effects of different concentrations of seaweed fermentation extract and seaweed alkali extract on seedling growth by hy- droponic experiment. [ Result]The results of seed soaking experiment showed that compared with the control,the treatment of seaweed fermenta- tion extract 100 times dilution promoted seed germination rate and seed germination potential of tomato significantly,the treatment of seaweed fermentation extract 200 times dilution promoted seed germination rate and seed germination potential of cucumber significantly; the treatment of seaweed alkali extract 200 and 400 times dilution promoted seed germination rate and seed germination potential of cucumber significantly ; the treatment of seaweed alkali extract 400 times dilution promoted seed germination rate and seed germination potential of tomato significantly. The results of hydroponic experiment showed that compared with the control,the treatment of seaweed fermentation extract 100 and 200 times dilution increased the root length, shoot height, fresh weight, dry weight, stem diameter of cucumber and tomato seedlings ; the treatment of seaweed alkali extract 400 times dilution increased the root length, shoot height, fresh weight, dry weight, stem diameter and root-shoot ratio of cucumber and tomato seedlings. [ Conclusion ] Seaweed fermentation extract and seaweed alkali extract could promote the seed germination and seedling growth of cucumber and tomato.
