- 摘要:
- 以番茄“美颜1319”为试材，采用正交实验的处理方法，在EC值具有显著差异（0.6、0.8、1.0 mS?cm-1）的3种混配基质中添加不同含量的海藻酸，研究了基质EC值与添加海藻酸对番茄幼苗生长的影响，以期为优质种苗的培育提供基质混配依据。结果表明：添加海藻酸促进番茄幼苗生长的效果与基质EC值关系密切，表现为在EC值较高（0.8、1.0 mS?cm-1）的混配基质中，添加3~6 g?L-1海藻酸可显著促进番茄幼苗的生长，表现为番茄幼苗茎粗、叶绿素含量、根冠比、全株鲜质量以及壮苗指数等指标显著高于对照，而添加9 g?L-1海藻酸处理出现抑制生长的现象；在EC值较低（0.6 mS?cm-1）的混配基质中，增加海藻酸添加量可明显促进番茄幼苗生长，但各项指标仍显著低于对照。证明番茄幼苗生长与基质肥料含量密切相关，以EC值为0.8~1.0 mS?cm-1的混配基质中海藻酸适宜添加量为6 g?L-1。
- Abstract:
- Tomato ‘Meiyan 1319’ was used as the test material.Three mixed substrates with significant differences in EC values(0.6,0.8,1.0 mS?cm-1) were selected and adding different contents of alginic acid as seedling substrate using the orthogonal test,which would provid theoretical basis for the cultivation of high-quality tomato seedlings.The results showed that the effect of adding alginic acid to promote the growth of tomato seedlings was closely related to the EC value of the substrate.In the higher EC value substrate (0.8,1.0 mS?cm-1),adding 3-6 g?L-1 alginic acid significantly promoted the growth of tomato seedlings,which showed that the stem diameter,chlorophyll content,root shoot ratio,fresh weight,seedling index of tomato seedlings were significantly higher than those of the control,while adding 9 g?L-1 alginic acid showed inhibition the growth.However,in the lower EC substrate (0.6 mS?cm-1),increasing the amount of alginate significantly increased the growth of tomato seedlings,but the indicators were still significantly lower than those of control.The results proved that the effect of adding alginic acid to promote the growth of tomato seedlings was closely related to the substrate fertilizer and the suitable substrate was 6 g?L-1 alginic acid adding in the substrate with EC value of 0.8-1.0 mS?cm-1.
