The invention provides an improved biogas slurry ecological treatment and cultivation system. The improved biogas slurry ecological treatment and cultivation system comprises a solid-liquid separationpond, a decomposition treatment pond, an aeration treatment pond, a PH (Potential of Hydrogen) regulating pond, an algae culture pond and an animal culture pond which are arranged according to a sequence of a treatment technology, wherein the solid-liquid separation pond, the decomposition treatment pond, the aeration treatment pond, the PH regulating pond, the algae culture pond and the animal culture pond are in end-to-end serial connection in sequence; the solid-liquid separation pond is used for carrying out precipitation treatment and disinfection treatment; the decomposition treatment pond is used for anaerobic and aerobic catabolism treatment; the aeration treatment pond is used for carrying out aeration treatment on biogas slurry; the PH regulating pond is used for supplementing and regulating the concentration, the PH and the nutritive salt component of the biogas slurry; algae are bred in the algae culture pond, nutrients can be supplied to the algae by utilizing the biogasslurry and biogas, and the biogas slurry and the biogas can be purified by the algae; multiple aquatic products are bred in the animal culture pond in an isolation way, and main feed is provided by the algae. According to the improved biogas slurry ecological treatment and cultivation system provided by the invention, circulation ecological breeding industry can be formed, and the environment is improved.

Disclosed are a preparing method and its product and application. Firstly, condense the pelagic unicellular alga in 1~2 degree, which is made into cream-condensed alga product, the dry it in low temperature or in vacuum, making the products which will not become harmful substance to juvenile of animal culture and can be diffused into alga juvenile of animal culture single cell with complete cell, finally, package it in vacuum or in nitrogen. The invention can be applied in all kinds of pelagic unicellular alga, and the products includes chlorella, nitzschia, chaetocero, can replace live pelagic unicellular alga to be applied in culture of seedling of animal culture in water, cultivation and strengthening of diet animal, especially for feeding diet animal .

The invention relates to a Chinese herbal medicine feed additive containing trace elements, namely a mixture of soluble salt of trace elements including copper, zinc, iron, manganese, magnesium, cobalt, iodine, selenium and the like, and three Chinese herbal medicines including fried white atractylodes rhizome, medicated leaven and fried endothelium corneum gigeriae galli. After being ground and crushed, the Chinese herbal medicines are mixed with the soluble salt of the trace elements to obtain the mixture, and then, the mixture, which accounts for 1.0wt%-2.0wt% of a feed, is added into the feed. The three Chinese herbal medicines in the feed additive have the effects of improving spleen and stomach, tonifying Qi and spleen and promoting digestion to relieve stagnation and are capable of effectively promoting absorption and utilization of the trace elements; the feed additive disclosed by the invention provides necessary trace elements for animal growth, so that the probability of slow growth and malnutrition caused by shortage of the trace elements is greatly lowered, diseases and death caused by slow growth and malnutrition are greatly reduced, the drug cost is lowered since the morbidity of animals is reduced, and the culture benefit is obviously increased; the Chinese herbal medicine feed additive fills up the blank in the wild animal culture industry and can be used for effectively promoting the sound development in the wild animal culture industry.

The invention relates to a LutrariasieboldiiReeve sea area beach plastic large tub artificial culture method, and belongs to the aquatic product animal culture technical field; the method comprises the following steps: preparing round plastic tubs with the waterproof surrounding and top opening; punching four 1.5-2mm holes on the top rim of the tub at equal intervals so as to fix a tub cover, wherein the tub cover uses a 10 mesh nylon rope net; conveying the tubs to a proper beach when the tide is gone and placing the tubs at the density of 1tub / square meter; filling the tub with sands to a position 2-4cm away from the top edge of the tub; using copper wire to fix the tub cover; uniformly placing medium-cultured LutrariasieboldiiReeve seedlings with shell length of 2-2.5cm into the tub at the density of 100-200 / square meter when the tide is gone again; culturing the LutrariasieboldiiReeve seedlings for 12-15 months with no separating seedling process until the LutrariasieboldiiReeve seedlings grow to a condition in which the shell length is 8.5-9.5 cm and body weight is 110-120g, harvesting the LutrariasieboldiiReeve. The novel LutrariasieboldiiReeve culture method is high in survival rate, fast in growth speed, low in cost, high in LutrariasieboldiiReeve culture benefits, convenient in harvesting, short in growth period, and large scale culture can be realized, thus greatly improving LutrariasieboldiiReeve culture benefits.
