The present application relates to the technical field of compound planting, in particular to a kind of southern winter idle field green manure optimization configuration efficient compound planting method, including step one, astragalus sinicus seed and rape seed banding sowing;Step two, astragalus sinicus seed and rape seed sowing promote growth treatment;Step three, astragalus sinicus and rape harvesting treatment;Step four, astragalus sinicus and rape crushing and turning back to field;Step five, strengthen and promote the management.Compared with prior art, a kind of southern winter idle field green manure optimization configuration efficient compound planting method is proposed in the present application, compared with traditional simple mixed sowing, in the yield of subsequent crop rice, rape straw decomposition rate, astragalus sinicus straw decomposition rate, >2mm soil aggregate formation, soil organic matter content and so on, there is greater improvement, it can be seen that the green manure optimization configuration efficient compound planting method is more conducive to soil fertilization and improve the yield of subsequent crop rice.

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 application discloses an enzyme-triggered self-assembly peptide hydrogel, a preparation method and application thereof, and belongs to the technical field of biomedical materials. The hydrogel comprises a peptide precursor Nap-YY(p)Y, an antibacterial compound daphnodorin and alkaline phosphatase; the peptide precursor is dephosphorylated under the action of the alkaline phosphatase, self-assembled to form a nanofiber network structure, and encapsulates the daphnodorin in the network structure. The hydrogel has a short gelation time (3-10 minutes), a moderate mechanical strength (a storage modulus G' of 130-170 Pa), a high encapsulation rate (greater than or equal to 75%), presents a biphasic release characteristic in a simulated wound liquid, and can maintain an effective therapeutic concentration for more than 7 days. The hydrogel has a significant synergistic killing effect on methicillin-resistant Staphylococcus aureus and a biofilm thereof, can effectively reduce a bacterial load of a wound and accelerate wound healing.
