Preliminary Study on Regulating Measures for Increasing Potassium Content of Tobacco Leaves Ⅰ. Effects of the physical regulating measures on the increase of potassium content of tobacco leaves;

Water spatial and temporal distribution by physical and chemical regulation method;

Prawn-fish-shellfish-algae optimal ecoculture and its bio-manipulation technique of water quality.;

According to the biomanipulation theory, the authors designed a series of stocking experiments in which three domestic fishes-silver carp, bighead carp and grass carp were introduced.

The present paper dealt with the ecological environmental characteristics of prawn culture in higher-place ponds and biomanipulation technology and quantitative analyses of suspended organic matters in farming water of the prawn green-farming experimental ponds at Zhanjiang city, Guangdong province.

The paper expounds the organism and methods of the amendment of aquatic ecosystem with biological control technique based on the deterioration of the Dalangdian Reservoir water environment.
