Abstract：The experiment of‘ venting method’ in laboratory and pot experiments were carried out
to investigate the characteristics of ammonia volatilization of special slow-release fertilizer in soil，and
its effect of special slow-release fertilizer on yield and quality of eggplant（Solanum melongena L.），
uptake of N，P and K，fertilizer use efficiency．The results showed that the special slow-release fertilizer（
QSRF） for vegetables could significantly reduce the volatilization rate of ammonia and accumulation
of ammonia volatilization in the experiment of‘venting method’in laboratory．At the beginning of
laboratory experiments，the highest average rate of ammonia volatilization was observed in large particle
urea（PUR）treatment．However，28 days later，the volatilization rate of special fertilizer（QCCF）
was the highest．Accumulations of ammonia apparent volatilization by QSRF had reduced by 62.17%
and 56.76%，compared with PUR and QCCF．Obviously in pot experiment，QSRF significantly improved eggplant yield. Yield of the 2 eggplant varieties under QSRF treatment had increased by 37.1%
and 37.8% than under the common compound fertilizer（ OCCF），and increased by 1.4% and 27.6%
than the commercial slow-release fertilizer（ MSRF）．Contents of VC and amino acid in fruit were increased
by QSRF treatment. Content of nitrate was evidently lower than that treated by OCCF．The apparent
fertilizer utilization rate of N and K was increased by QSRF treatment，while no obviously effect
was found on apparent fertilizer utilization rate of P.
