In order to understand the effect of man-made disturbances of soil, purple photosynthetic bacteria, potassium permanganate and high-temperature calcinations of the oyster-shell on clam cultivation. The treatments will be divided into A group without any treatment (control group), B group of man-made disturbances of soil, C group the use of purple photosynthetic bacteria 15ppm, D group using the oxidant potassium permanganate 2ppm, E Group used the high-temperature calcinations of the oyster shell powder 20ppm, each group of triplicate . After 60 days of rearing, the treatment group clam's weight gain, fatness and feed conversion factors have significant differences exist, to C group and E group of the best. E Group which using oyster shell powder caused by pond water pH significantly higher than the other four groups. The treatment groups of ammonia - nitrogen and nitrite - nitrogen was significantly lower than the control group, in which to add the photosynthetic bacteria (C) of the ammonia - nitrogen and nitrite - nitrogen removal efficiency significantly. Each treatment group has existence of significant differences at redo potential of soil, to C group and E group of the best. Each treatment group of the solubility soil ammonia - nitrogen and sulfur are also significant differences that C group, D group and E group were significantly lower than the control group. The results of this study were found to add photosynthetic bacteria, or oyster-shell powder in the test group can promote growth of hard clam and improve the pond bottom soil environment. This experimental production efficiency and the economic efficiency all increase the purple photosynthesis bacterium treatment group to be best, the artificial perturbation subsoil treatment group is worst. The technological innovation and the technological innovation cost may use in explaining that of production function this experiment delivers the effect, but because is the decreasing return scale, must therefore aim at the innovation technology and the cost again seeks a more appropriate pattern. In addition, vacuum packing clam preserve temperature by 6-9 ℃ good, even if under 17-19 ℃ preserved conditions, may also maintain approximately 12 day-long to live the fresh clam quality, is advantageous in uses the ship transport for sale abroad the transport mode. The hard clam after the weight graduation, the size difference is small, is advantageous to the high quality price promotion.
