Research Progress of Induced Breeding on Space Flight and the Prospect on its Application in Grass Breeding;

Development of sequence characterized amplified region of plant and its application on grass;

Effects of some water retention materials as soil conditioners on improving grass seedling emergence under dry and saline soil conditions;

The results showed that for TN,TP,CODMn,NH4+-N and the transparency the sequence of treating effect is basically: strip aquatic mats> AquaMats> artificial aquatic mat>plant carpet>the control;in it the removal rates of TN,TP,CODMn by strip aquatic mats were 97.

The quality of eutrophic waters was improved by the algae-bacterium biofilm, which covered over the artificial aquatic mat made from a kind of mend macromolecule material.

Seasonal dynamics of biomass and nutrition of artificial grassland established in "black soil type" degraded grassland in Gemutan;

Study on the changes of soil nutrients,microbial biomass P and neutral phosphatase activity of artificial grassland sown in different years in the headwaters of the Yangtze and Yellow Rivers;

Characteristics of artificial grassland plant communities with different establishment duration and their relationships with soil properties in the source region of Three Rivers in China;

Effect of Chinese medicine extract Ren Xian Cao on the replication of hepatitis B virus;
