The invention discloses a shrimp ecological culture and a polyculture method based on facility microalgae culture, including preparing corresponding microalgae and shrimp fry; then putting them into a culture tank for culture; The cleaning control system monitors the breeding ponds; finally, the breeding is continued; the cleaning control system includes an algae recording unit, a data recording unit, a content detection unit, a single database, a data prediction unit, a single shrimp acquisition unit, a processor, a display unit, It is recommended to generate a unit and a management unit; the present invention uses the cleaning control system to monitor the number of microalgae in the breeding pond in real time, and also combines the growth of shrimp, the number of breeding days and the relevant feeding amount to reasonably predict the corresponding time. The number of microalgae will reach the corresponding upper limit, and according to the number that reaches the upper limit, it will be determined whether local targeted cleaning or overall cleaning is required; it is easy to treat differently.

The invention relates to the technical field of cell engineering tissue culture, and aims to provide a method for effectively preserving embryogenic callus of Acorus calamus. The method for effectively preserving the embryogenic callus of Acorus iris includes the steps of material collection, callus induction culture, screening and preservation of the embryogenic callus. The invention uses the young embryos of calamus calamus as explants, which has extremely low pollution rate, high callus induction rate, good embryogenicity of callus, and high reproduction coefficient, and at the same time solves the problem of easy browning and differentiation in the preservation of calamus calamus callus Serious problems, strong practicability, easy operation and good promotion.

The invention relates to a tissue culture propagation method of Polygonatum multiflorum, comprising the steps of in an aseptic environment, collecting embryo from mature seeds of Polygonatum multiflorum by peeling, and sterilizing the embryo; inoculating the sterilized embryo to a callus induction medium, and performing light-free culture for 7-12 days so that the embryo expands to form a callus;cutting the callus into small pieces, inoculating the pieces to a callus subculture medium, and culturing for 18-25 days under light intensity of 800-1000 lux and daily lighting time of 10-12 h; cutting the callus subjected to subculture in step S3 into small pieces, inoculating the pieces to a sprouting medium, and culturing for 28-35 days under the light intensity of 1200-1800 lux and daily lighting time of 10-12 h, and inducing to obtain cluster buds; inoculating the robust single ones of the cluster buds to a rooting medium, and performing rooting culturing. The method herein helps greatlyreduce pollution rate of a tissue culture process, and improve propagation efficiency and seedling quality.

The invention discloses a propagation method of Vernonia amygdala. Specifically, the secondary buds of Vernonia amygdala are placed in a rooting medium for pre-cultivation to obtain aseptic seedlings, and then the aseptic seedlings are cut into the substrate for cultivation. After rooting, Plant in pots after new leaves have grown. The present invention combines tissue culture technology and cutting technology to propagate Vernonia amygdala to achieve complementary advantages of the two. The pre-cultivated and unrooted aseptic seedlings are cut into the mixed matrix of peat soil, river sand and vermiculite to take root, which overcomes the need for cleaning and cultivation. It is helpful to improve the survival rate due to the problems of root and susceptibility to pathogenic bacteria; tissue culture technology can be used to provide large-scale cutting propagation materials all year round, meeting the requirements of large-scale production and annual production of seedlings.

The invention belongs to the technical field of forest creatures, and discloses a cultivation method for quickly obtaining lycium ruthenicum regeneration seedlings. The cultivation method comprises the following steps: disinfection of seeds, obtaining of germfree seedlings, induction of a callus, obtaining of adventitious buds and induction of roots. According to the cultivation method, the callus is directly obtained from the germfree seedlings of lycium ruthenicum, and the lycium ruthenicum regeneration seedlings are cultivated through a tissue culture method; compared with a conventional method for inducing the callus through leaves or stems of the seedlings, the cultivation method has the advantages that the tissue culture time is greatly shortened, and cultivation cost of the lycium ruthenicum is greatly reduced; meanwhile, the cultivation efficiency is effectively improved, and the transplanting survival rate of the regeneration seedlings reaches up to 98 percent. The lycium ruthenicum obtained through the cultivation method has the characteristics of being high in genetic stability, low in cost, short in seedling growing period, high in reproduction coefficient, and easy and convenient to operate.

The invention relates to a TV special effect controlling method for controlling the play function of the TV, comprising the following steps: receiving information commands and dispatching the information according to classes, the information commands also comprising play control starting information; transmitting key information at specific intervals after the ply control starting information is received, playing the TV at specific intervals, namely transmitting the key information at specific intervals to fast forward / rewind keys, maintaining fast forward / rewind information in a running state till receiving the special effect control stop information or detecting the play over during a play process, and then stopping transmitting the key information at specific intervals. The invention also relates to a television capable of effectively and conveniently controlling the TV play function.

The invention relates to prevention and treatment of bone diseases caused by glucocorticoid medicines. Concretely, the invention relates to application of Wnt signal pathway to prevention and treatment of bone diseases caused by glucocorticoid medicines. Expression of C / EBPalpha factor is down regulated at a later period that BMP2 induces a mouse mesenchymal stem cell line C3H10T1 / 2 to be differentiated into osteoblast, and overexpression of the factor can inhibit differentiation of osteoblast. The reason causing down-regulated expression of C / EBPalpha is that distal promoters (-1286bp / -1056bp) of C / EBPalpha are subjected to hypermethylation at the differentiation later-period of osteoblast and are silenced. Interruption of the methylation process promotes high expression of C / EBPalpha and leads to osteogenic / adipogenic differentiation unbalance. A Dex-induced osteoporosis model proves that Wnt / beta-catenin signal pathway has important regulation and control effects on expression and methylation of C / EBPalpha in differentiation of osteoblast. A stimulant / activator of the pathway is capable of rescuing osteogenic / adipogenic differentiation unbalance caused by Dex.
