| 摘 要： | 盆栽试验结果表明,棉花施用稀土可以对其生长产生一些生理效应,不论是用稀土浸种或叶面喷施,都可促进生长,使棉花根系发达,吸收养分多,叶片叶绿素含量和光合作用率提高,电解质外渗率减低,并引起叶片微形态结构发生了变化,说明棉花施用稀土增产有一定的生理基础.

| Abstract: | The result of pot expcriments of rare-earth elements application to cotton showed that physiological response occurcd during growth period.Both seed soaking and spraying rare-earth elements could improve growth of root,inerease absorption of nutrient elements, raise chlorophyll content in leaf,heighten photosynthesis rate and reduce electrolyte leakage rate.This physiological response was also observed in micro-morphological structure of leaf. It is one rcason for the effect of rare-earth elements application on the yield. |
