It analyzes problems from the positive and negative both sides,identifying the restraining force and the promothing force in the reform environment,organizing these information to ascertain the best method on the environment improvement.

For sterilizing the Pyricularia grisea with Trichoderma aureoviride, the restrain ability of Trichoderma harzianum, Trichoderma koningii, Trichoderma aureoviride and Trichoderma viride on the Pyricularia grisea were compared, by bi-culture and the metabolite on pathogen mycelia growth and spore germination.

The enzymatic properties, heat stability, activation and inhibition kineticsof wheat leaf phosphatase and thylakoid membrane phosphatase were studiedusing wheat pH82-2-2, anticipating to supply theoretical base for regulatingphotosynthesis, improving phosphorus nutrition by regulating enzyme activity.

The influence of disulfide bonds on the conformational changes and activities of refolded phytase, the effect of deglycosylation on the stability of the phytase, the effect of metal on the conformation, activities and stability and inhibition kinetics of substrate, product and product analogues on the phytase was studied using Aspergillus sp.
