- 摘要:
- 以马铃薯克新13为材料，采用不同浓度0.5%、1.0%、1.5%、2.0%、2.5%的硫酸镁溶液浸种薯处理，以清水为对照，通过测定株高、茎粗、叶面积指数LAI、叶片叶绿素含量、根系活力、干物质积累，研究了硫酸镁对马铃薯幼苗建成的作用效果。结果表明：适宜浓度的硫酸镁浸种薯有利于马铃薯幼苗建成，当其浓度达到2.0%以上时则表现出了抑制作用。
- Abstract:
- Taking Solanum tuberosum Kexin 13 as the material，adopting different concentrations0.5%，1%，1.5%，2%，2.5%of magnesium sulfate solution soaking the seed tuber and water as control，the effect of magnesium sulfate on the seedlings growth of potato was studied by measuring plant height，stem diameter，leaf area indexLAI，chlorophyll content of leaves，root activity，accumulation of dry matter.The results showed that soaking treatment with appropriate concentration of magnesium sulfate was favorable for the potato seedlings-building，whereas it turned out to have inhibitory effect when the concentration of magnesium sulfate was above 2%.
