The invention discloses eco-nutritional compound feed for laying hens at an egg-laying peak and a preparation method of the eco-nutritional compound feed. The eco-nutritional compound feed for the laying hens at the egg-laying peak comprises components in percentage by weight as follows: corn, bean pulp, rice bran, calcium hydrophosphate, rock flour, baking soda, sodium chloride, soybean oil, compound trace elements for the laying hens, compound vitamins for the laying hens, 50% choline chloride, a bacillus coagulans preparation, a fructo-oligosaccharide preparation, an DL-methionine, compound enzyme for the laying hens, phytase, montmorillonite and zeolite powder. The nutritional requirement of the laying hens can be met, the immunity and the anti-stress capacity of the laying hens can be effectively improved, the disease rate is reduced, the egg laying rate is increased, the lasting time of the peak is prolonged, the quality of eggs is improved, the environment of henhouses can be improved, and the eco-nutritional compound feed is a novel laying egg feed product integrating nutrition, the anti-disease property, promotion of a high yield and pollution-free property.

The invention discloses a method for scientifically and precisely breeding rice field eels. The method is characterized in that a culture pond is arranged in the east-west direction, a length-width ratio of the culture pond is 3:2, the area of the culture pond ranges from 2000m<2> to 10000m<2>, the heights of ridges of the culture pond range from 1.8m to 2.0m, the water level of the culture pond needs to be kept stable in a range from 1.4m to 1.5m for a long term, and water inlet and drainage facilities of the pond are perfect; the pond needs to be cleaned and disinfected 10-15d before rice field eel seeds are released into the pond, water in the pond is pumped completely, whether loopholes are formed in the pond or not is checked, then the pond is cleaned by the aid of quicklime, the consumption quantity of the quicklime ranges from 1125kg / hm<2> to 2250kg / hm<2> when the depth of water in the pond ranges from 7cm to 10cm, the pond is cleaned by the aid of bleaching powder if the water in the pond cannot be completely drained, new water is filled into the pond 7d after the pond is cleaned and needs to be filtered in advance, and basic fertilizers are applied after the water is filled into the pond. The water is cultivated by a process including that organic fertilizers such as chicken manure and pig manure are stacked at four corners of the pond, consumption of the organic fertilizers ranges from 2250kg / hm<2> to 3000kg / hm<2>, and the rice field eels can be bred in the pond 5-7d after the fertilizers are applied. The method has the advantages that fast growth of the rice field eels can be promoted by means of adding the compound microbial fertilizers, the EPA (eicosapentaenoic acid) content is increased, rice field eel diseases are reduced, the quantity of shrimps which die of diseases is reduced, beneficial microorganisms in the water are increased, and both the final quality and the quality are improved.

A device for processing water of river and lake and its method are disclosed. Its filtering cartridge includes four ones arranging in a circle, with pipes connecting each one adjacent and there is separating surface in the upper and middle of it, above which is the cleaned water tank with a U-typed foam exhausting pipe linking to the water feeding pipe of filtering cartridge, and the other end of the pipe is extended into the foam-exhausting tank whose lower part is linking to the dirty-exhausting exit; each water feeding pipe of filtering cartridge is linking to a support jacket pipe, and an sleeve-typed exhausting device is supported by four support jacket pipes, whose bottom is linked with a water feeding pipe and V-typed water channel placing among the inner and outer inner sleeve, there is water curtain formed on the bottom edge and two upper ones. Besides, time register can be installed on the foam-exhausting pipe for automatic washing. The machine needs no human to operate has small volume, exhausts foams water effectively, saves energy and water source, suitable for dealing with pollution of river and lake.

The invention discloses a special compound microorganism fish fertilizer for carp and a preparation method thereof. The special compound microorganism fish fertilizer comprises the following components by weight: 2 to 4 parts of nitrogen-fixing bacteria, 1 to 3 parts of phosphate solubilizing bacteria, 3 to 5 parts of ferment bacteria, 50 to 60 parts of fish meal, 75 to 80 parts of a soybean cake, 20 to 30 parts of wheat bran, 70 to 80 parts of rice bran, 10 to 14 parts of brown sugar, 8 to 10 parts of yeast powder, 12 to 15 parts of salt, 80 to 85 parts of chicken manure, 60 to 65 parts of waterweed, 10 to 13 parts of calcium hydroxide, 15 to 20 parts of urea, 3 to 5 parts of potassium sulfate, 3 to 5 parts of ferric citrate, 0.2 to 0.4 part of vitamin B1, 0.1 to 0.3 part of vitamin B12, 1 to 4 parts of baical skullcap root, 3 to 5 parts of isatis root and 4 to 6 parts of liquorice. The compound microorganism fish fertilizer provided by the invention can promote rapid growth of fish, improve quality and quantity of fish, reduce fish diseases and allows beneficial microorganisms in water to be increased and growth of algae in a fishpond to be retarded.

The invention discloses a composition containing a herbal extract and a makeup material composition. The composition containing the herbal extract comprises 5-20% of a guava leaf extract, 5-20% of an angelica sinensis whole grass extract, 5-35% of a tea extract and a lotus leaf extract by mass, totaling 100%. The makeup material composition is the composition containing the herbal extract. The composition which contains mixed extracts such as the lotus leaf extract, the tea extract, the guava leaf extract and the angelica sinensis whole grass extract can inhibit reproductive growth of propionibacterium acnes which causes acnes of skins and inflammatory response, has a very good improving effect on skin problem, promotes blood circulation of the skins and maintains lubricative and clean skins, and is free of irritation and side effects and high in safety when being used.
