The germination test of Sporocarps of Microlepia hancei prantl had been done, the callus can be induced from the delicate stem of Microlepia hancei prantl; The inducement and proliferation medium of callus was MS＋6-BA2 mg/L+NAA0.2 mg/L;the optimal combination of hormones of buds differentiation was MS+6-BA 0.4 mg/L; the effect of MS medium in radication culture was better than 1/2MS, the roots of plants were all efficiently induced in MS medium without reference to adding IBA、NAA or IBA＋NAA, the rate of radication was high; the effect of seedling cultured in the mixture of perlite and turf soil was better than perlite、garden soil and river sands.the mixture of perlite and turf soil has the excellences such as ventilate、water conservation 、nourishment and so on,the survival rate was higher and seedling substance was also hale.

试验进行了华南鳞盖蕨孢子果的萌发试验，并利用幼嫩茎段进行诱导愈伤组织；愈伤组织的诱导与增殖培养基为MS＋6-BA2 mg/L+NAA0.2 mg/L；其芽分化最佳激素组合为MS+6-BA 0.4 mg/L；生根培养中MS基本培养基比1/2MS效果好，MS基本培养基不论附加生长素IBA、NAA或IBA＋NAA，均能有效地诱导植株生根，生根率高；假植以珍珠岩和泥炭土的混合物为基质效果优于珍珠岩、菜园土和河沙，具有通气、保水、营养等优点，假植成活率高，苗势健壮。

The result of the test showed that the fed quantity of TiO2 was 1.25 mg／mL,the photocatalytic degradation of the pyridine was in conformity with the first order kinetic equation,the feeding of 0.2％H2O2 obviously increased the degradation rate of the pyridine and the nitrogen in the pyridine converted into ammonia nitrogen;the pearlite-loaded TiO2 had the same catalytic effect as that of powered TiO2 and was easy to recover and reutilize.

以钛酸四丁酯水解法制备TiO2，采用溶胶一凝胶法在膨胀珍珠岩上负载TiO2，在UV-TiO2体系中对水中吡啶进行光催化降解，结果表明：TiO2加入量为1.25mg／mL，吡啶的光催化降解符合一级动力学方程，加入0.2％H2O2可明显加快吡啶的降解速度，吡啶中氮转化为氨氮，珍珠岩负载型TiO2与粉末TiO2具有相同的催化效能，且便于回收和重复使用。
