Method for cyclically utilizing water plants of river crab pond

The invention provides a method for cyclically utilizing water plants of a river crab pond. The method comprises the following steps: managing the river crab pond: cleaning sludge in the river crab pond, disinfecting the river crab pond by utilizing quick lime, bleaching powder and tea seed meal, and then insolating the pond; managing the water plants, applying fertilizer and throwing in bellamyaquadrata: arranging a fencing grass planting region in the river crab pond, planting the water plants, and cutting off the water plants in summer; adding the bellamya quadrata before Qingming Festival; throwing in river crabs: throwing in young river crabs at the last ten-day period of March; carrying out grass carp intercropping: placing a grass carp intercropping net box in the pond at the firstten-day period of June; throwing in grass carp fries: throwing in the grass carp fries into the grass carp intercropping net box at the first ten-day period of July; feeding feed: only feeding feed to the river crabs, but not feeding feed to the grass carps, and feeding the grass carps with the water plants cut from the river crab pond; regulating and controlling the water quality of the river crab pond. According to the technical scheme of the invention, efficient combination of a plurality of types of high-quality aquatic products is realized, the utilization rate of a water body and the planted water plants is improved, the output-input ratio is improved and the comprehensive economic benefit of the river crab pond is remarkably improved.

Method for cultivating a Procypris merus-Carassius auratus auratus hybrid and method for farming Siniperca chuatsi

The invention relates to a method for cultivating a Procypris merus-Carassius auratus auratus hybrid and a method for farming Siniperca chuatsi; the first method comprises the steps of subjecting Procypris merus as a female parent and Carassius auratus auratus as a male parent to artificial spawning induction, then carrying out artificial fertilization to obtain fertilized eggs, and debonding andhatching the fertilized eggs to obtain the Procypris merus-Carassius auratus auratus hybrid. According to the invention, the Procypris merus-Carassius auratus auratus hybrid is creatively bred by taking Procypris merus as a female parent and Carassius auratus auratus as a male parent, and is used as a feed fish for culturing Siniperca chuatsi. The limits on large-scale cultivation of Siniperca chuatsi due to natural conditions of the middle and northern parts of China, feed fish cultivation seasons and other factors can be resolved; the methods are suitable for southern areas and northern areas of China, help ensure the marketing of Siniperca chuatsi products in cold seasons; the ratios of protein content, fat content, total essential amino acids to total nonessential amino acids in the products are high; the muscle quality of Siniperca chuatsi fed with the Procypris merus-Carassius auratus auratus hybrid is higher than that of Siniperca chuatsi fed with Carassius auratus auratus.

Root fixing backrest plastic chair

The invention relates to a root fixing backrest plastic chair. The root fixing backrest plastic chair comprises chair legs, a chair plate and a chair backrest, and is characterized in that the chair backrest is a platy plate of which the peripheries of the chair plate extend upward; a connector, vent or split hole is formed between the two adjacent platy plates; the middle of the platy plate is an outward inclined plane; the upper part of the platy plate is an outward arch-shaped cambered surface; the chair legs are connected to the bottom of the chair plate; the upper head of a stand bar is provided with a cross bar which extends toward the center to form a support frame. The chair backrest is like bamboo leaf or leaf similar to grain, the lower part of the leaf extends upward from the peripheries of the chair plate and unfolded to form the platy plate, and the connector, vent or split hole is formed between the platy plates, so that the connection strength of the platy plate is improved, the whole backrest is good in permeability and attractive in appearance by adopting the vent or the split hole; the middle part of the platy plate is an outward inclined surface and the upper part is an outward arc-shaped cambered surface, so that the appearance is lifelike and full of anima, and people feel comfortable when lying against the chair.

A biologically active immune preparation for enhancing sheeppox vaccine antibody and its preparation method

The invention relates to a biological immune preparation for strengthening a goatpox vaccine antibody and a manufacturing method of the biological immune preparation. The steps adopted in the method include that the fresh spleen of a healthy yak is selected, after fat, the envelope and the internal connective tissue are removed, the spleen is subjected to freezing preservation, the yak spleen obtained after freezing preservation is taken out and melted and is minced through a tissue stamp mill, after sterile tri-distilled water with the same weight is added, the high-speed tissue stamp mill is used for conducting homogenizing at a high speed for two times, and homogenizing is conducted 10 min each time; and prepared homogenate is frozen at the temperature of minus 20 DEG C, freezing and thawing are conducted repeatedly for five times, centrifuging is conducted after the last time of thawing, supernatant is taken and put into a dialysis bag, the supernatant is dialyzed overnight under the environment of 0 DEG C to 4 DEG C through pyrogen-free cold normal saline, dialysate outside the bag is collected and is subjected to filtration sterilization through a filtering film, and the dialysate is subjected to sterile subpackaging and is then subjected to freezing preservation. After the biological immune preparation enters an organism, the effect of the biological immune preparation can be rapidly developed and can last for several months or even longer, the immune antibody level of the vaccine is effectively improved, the biological immune preparation can be rapidly and completely absorbed by the organism without any residue, weight increasing is obvious after the biological immune preparation is injected into the organism, and a goat can be lively in spirit.
