Abstract: A brazing wire includes a brazing tube having an inner cavity and a flux filled in the inner cavity. A trench is provided on an outer peripheral surface of the brazing tube, and the trench extends along an axis of the brazing tube or spirally extends around the axis. A forming mold of the brazing wire includes a mold body having a molding cavity therein. An inner wall of the molding cavity is provided with a protrusion. When the brazing wire passes through the forming mold, the protrusion is used to form the trench. The forming method of the brazing wire includes the following steps. The brazing tube passes through the forming mold, and the trench is formed on the outer peripheral surface of the brazing tube by the protrusion. The trench extends along the axis of the brazing tube or spirally extends around the axis.

Abstract: A growth-promoting bacterial agent capable of improving content of soybean oil, preparation method, and use thereof are provided. The growth-promoting bacterial agent is fermented by a DW1 strain, the classification name of the DW1 strain is Bacillus sp., the DW1 strain is deposited in the China Center for Type Culture Collection on Jul. 16, 2021, and the deposit number is CCTCC NO: M 2021889. The growth-promoting bacterial agent of the present disclosure has the ability to dissolve insoluble phosphorus and insoluble potassium and can increase content of readily available phosphorus and readily available potassium in the soil, which has an obvious promoting effect on the growth of soybean and improves soybean yield. The growth-promoting bacterial agent of the present disclosure promotes bacteria and can significantly improve the content of soybean oil. At the same time, it has an affinity of soybean agglutinin and can agglutinate with the soybean agglutinin.
