T
he biochars were derived from Gossypium
barbadense
straw, Z. mays straw and pig manure through pyrolysis at
temperatures 300˚C and 500˚C under limited oxygen condition. The influences of the biochars on seed germination
and early seedling growth of Chinese cabbage (
Brassica rapa L
.) and wheat (
Triticum aestivum L
.) in the aqueous solutions
containing Cd(II) were evaluated under laboratory conditions. The research comprised 4 amount rates (0, 0.5%, 1% and 2%/
glass) of 6 types of biochars. Cd(II) was added as chloride salt in solution in concentration 10 mg/L. The results of sowing
seeds showed that addition of biochar changed such characteristics as pH, electroconductivity (EC), availability of ammonium
and Cd(II). It was determined that germination and root length had been decreased with higher amount of biochar, at the
same time lower amount showed increase. A large amount of biochar (2%/glass) had negative effect on the root length of
Brassica rapa L
. and
Triticum aestivum L
. while fewer biochar (0.5 g/glass) indicated a better result, increased or no effect.
The percentage of germination did not show regularity. Pearson's correlation coefficient showed association between pH and
Chinese cabbage germination and root length had weak positive relationship (0.2 < r > 0.29), between EC and Cd(II) and root
length and germination of both seeds had strong positive relationship (0.40 < r > 0.69), another all had no or had negligible
relationship (0 < r > 1.9).
