The invention belongs to the technical field of gene engineering and salt-tolerant plant cultivation, and particularly relates to a wild soybean salt-tolerant gene and application thereof. The gene GsWRKY53 responding to salt stress is identified by performing expression analysis on the gene of the wild soybean under salt treatment, the salt-tolerant gene GsWRKY53 in the wild soybean is transferred into a soybean cotyledon through an agrobacterium transformation method for the first time, and the gene function of the gene can be quickly and accurately verified by verifying the influence of the salt-tolerant gene GsWRKY53 on soybean hairy roots. Experiments prove that the fresh weight, the dry weight and the number of hairy roots of soybeans can be reduced by overexpression of the wild soybean salt-tolerant gene GsWRKY53, which indicates that the GsWRKY53 plays a negative regulation role in the salt tolerance of the soybeans. According to the technical scheme, a foundation is provided for screening and verifying the salt-tolerant functional gene and further screening or cultivating salt-tolerant plant varieties, especially salt-tolerant soybean varieties, so that the method has a good practical application value.

This invention discloses a dual-component thrust attitude control engine, comprising a mounting plate, a swirling mixer, an igniter, and a combustion chamber nozzle. The mounting plate contains two isolated gas chambers, each with an intake pipe connected to its inlet and an on / off controllable solenoid valve at its outlet. The two inlets of the swirling mixture are connected to the outlets of the two gas chambers, and the outlet of the swirling mixer is connected to the inlet of the combustion chamber nozzle. The swirling mixer is used to swirl and mix the gas input into it before outputting it. The igniter is used to ignite the mixed gas input into the combustion chamber nozzle. The combustion chamber nozzle is used to supply the combusted mixed gas for combustion output. This configuration solves the problem that existing technologies cannot simultaneously achieve compact structure, high mixing efficiency, and excellent thermal management performance.

The invention discloses a rice nitrogen efficient utilization gene OsNAC15, a protein coded by the gene OsNAC15 and application of the gene OsNAC15, and belongs to the technical field of molecular breeding. The invention discloses the effect of the OsNAC15 gene in efficient utilization of rice nitrogen for the first time, the overexpression of the rice OsNAC15 gene significantly improves the nitrogen utilization rate and yield of a plant, and the mutation of the OsNAC15 gene significantly reduces the nitrogen utilization rate and yield of the plant; the mutant and / or overexpressed OsNAC15 gene has the advantages that the plant development is normal, the regulation and control of the nitrogen nutrition utilization rate of the rice can be realized by precisely regulating and controlling the expression level of the gene, the biomass and yield of crops are further improved, the environmental pollution is reduced, and the application prospect in the agricultural field is wide. Especially in the aspect of cultivating crop varieties capable of efficiently absorbing and utilizing nitrogen fertilizer, such as rice, corn, wheat, soybean, cotton, rape and other key crops, the wide application of the strain is expected to lead the agricultural production to be more environment-friendly and efficient, and a powerful scientific and technological support is provided for solving global grain safety problems and environmental protection challenges.

The invention belongs to the field of plant genetic engineering, and provides application of alfalfa cFBP protein in regulation and control of plant types, and the nucleotide sequence of an alfalfa cFBP protein coding gene is SEQ ID NO.1 or SEQ ID NO.3. The invention further provides a preparation method of the alfalfa cFBP protein. The alfalfa cFBP protein coding gene can positively regulate and control the plant height, the branch number and the biomass of alfalfa, and the plant height, the branch number and the biomass of the plant after overexpression of the MscFBP gene are remarkably improved compared with those of a control material. According to the invention, the MscFBP gene is overexpressed through a genetic engineering technology, so that the transgenic alfalfa with remarkably improved biological yield is successfully obtained, and important normal forms and gene resources are provided for cultivating high-yield plant varieties.

The invention discloses application of melatonin to reduction of negative effects of herbicides on plants. The melatonin can relieve elongation reduction, dry weight reduction, chlorophyll reduction and lipid peroxidation caused by fluroxypyr-mepthyl and reduce accumulation of fluroxypyr-mepthyl in rice. The melatonin can be used for reducing threats of crops polluted by fluroxypyr-mepthyl to human health.

The utility model discloses a honey heating crystal melting and pressure filtering device, which relates to the technical field of honey processing and comprises an equipment platform, a heating tank and a pressure filtering tank, the heating tank is mounted on the equipment platform, and an electric heater is mounted at the bottom of the heating tank.
