We have analyzed the ecological disaster prevention mechanism in Hunan province in the aspect of decentralized water store and expanded water capacity,instant water store and repetitive water store,graded flow-block-up and barrier flow-block-up.

The lasting effects of integrated ecological management on rodents control in army units;

The study was to identify Trichoderma 05-1,determine biocontrol mechanism and fermentation condition.

The intention of this experiment was to research the fermentation condition of Trichoderma T-115 D, antibiotic activity of Phytophthora sojae hyphae to fermentation filtrate, study on biocontrol mechanism of T115D and Biocontrol effects experiment of Trichoderma T115D fermentation against Phytophthora root rot.

The ecological mechanism of fertility transition for a thermo-sensitive genic male sterile(TGMS) line,Qiong-68 ms,was evaluated by means of sowing by stages,investigating leafage and detecting the fertility of pollen.

Its basic ecological mechanism is to build the unique Blue Niche during the marketing process,which includes target market exploitation,product development,pricing,channel design and media design,so as to shake off the dependence on intensive market,optimize the market environment and realize the harmony between economic benefit,social benefit and enviro.
