Study on Inoculation Technology and Effect of Inoculation with Frankia on Casuarina

The inoculation technology and effect of inoculation with Frankia on Casuarina were studied.The results showed that optimal time for inoculation with Frankia on Casuarina was the seedlings of 3～4 cm in height;the optimal methods was before inoculation with Frankia on seedlings cut off their tip of roots.There were no differences among the inoculum of dry or wet alginate beads、peat、vermiculite、liquid on effect of inoculation with Frankia. A high quantity of inoculum for inoculation with Frankia on seedlings was better than the low on effect of inoculation.The dual inoculation of seedlings with Frankia and Bacillus cereus was better than only Frankia on effect of inoculation.The seedlings applied with P、Mg、Ca、Co and mixed with lime in red soil can promoted their growth and indulation.The inoculation with Frankia on seedlings was not only increasing total N and available N of soil,but also organic matter and available K.
