The invention discloses a breeding method for the new line of hybrid Crassostrea hongkongensis and Crassostrea gigas. According to the technical links of one generation preparation of the female Crassostrea hongkongensis and male Crassostrea gigas hybrid seed, environmental effect detection, breeding potential assessment, optimal class group selection self propagation and the like, a new line of hybrid gigas suitable to the local place can be obtained by 3-4-generation breeding. According to the breeding method for the new line of the hybrid Crassostrea hongkongensis and Crassostrea gigas, which is disclosed by the invention, gametogamy sovereignty nuisance between gigas seeds is overcome; a series of problems of slow growth speed, weak viability and exceeding sterility of hybrid F1 can be solved; the selection function on an excellent gene type by environmental stress is quickened; a breeding method suitable for the local new line of Crassostrea hongkongensis and Crassostrea gigas can be created. According to the new line bred with the breeding method disclosed by the invention, the applicable range on the temperature and the salinity by the gigas is widened, and the yield is improved by more than 30% (if being compared with parents). The breeding method for the new line of Crassostrea hongkongensis and Crassostrea gigas has the advantages of strong practicality, easiness in popularization and the like.

The invention relates to a method for biologically testing chemoreception potential of plant root system secretions, belonging to the field of biological test technology.The method comprises the following steps: preparing agar liquid with a concentration less than or equal to 0.3% with water; sterilizing the agar liquid and pouring the agar liquid into a culture dish; disinfecting the donor plantand sowing the donor plant in the culture dish; sealing the culture dish, keeping the culture dish in a culture room with a temperature of 25-28 DEG C for 12 hours and culturing for 10-14 days in thebright / dark environment; removing all plants to be tested from the 11th day to the 15th day; disinfecting the receptor plant and sowing the receptor plant in the culture dish with the donor plant removed; sealing the culture dish, keeping the culture dish in a culture room with a temperature of 25-28 DEG C for 12 hours and culturing for 5-7 days in the bright / dark environment; then taking out thereceptor plant to measure growth amount thereof and growth amount of the receptor plant not affected by the donor plant; calculating influence of the plant root system secretions on the growth of thereceptor plant according to the measured growth amount to carry out chemoreception potential assessment.The invention is characterized by excluding competition among plant species for water and nutrient and fully reflecting effects the donor plant root system secretions have on the receptor plant.

The invention discloses a method for evaluating the aggregation potential of loads participating in demand response. The method includes the following steps: Step 1) Based on the input and output physical models of the three types of household loads of air conditioners, water heaters and electric vehicles, the calculation of household comfort characterization indicators is proposed. The comfort index value of each load; Step 2) Considering the influence of factors such as load operating characteristics, user comfort, user travel plans, and demand response principles, establish a load aggregation response model; The effective response power characterizes the aggregate response potential in this period. This method can effectively evaluate the aggregated response capability of the intelligent load group, so as to fully tap the response potential of the load when there is an emergency power shortage in the power grid, and reduce the pressure on the generator's primary and secondary frequency regulation backup.
