This invention relates to the field of water-saving valve technology and discloses a combined valve structure with a self-locking function, comprising a main body, a motor fixedly connected to the bottom of the main body, a water inlet pipe fixedly connected to the rear side of the main body, a water outlet pipe fixedly connected to the side of the main body away from the water inlet pipe, a central control unit fixedly connected to the top of the water outlet pipe, a top assembly fixedly connected to the top of the main body, a rotating assembly rotatably connected to the inner wall of the main body via bearings, and a first outer shell fixedly connected to the bottom of the water outlet pipe. By setting a first filter screen and a first outer shell, impurities such as iron filings, silt, and suspended solids mixed in with the water can be effectively filtered during irrigation. At the same time, by utilizing the inclined angle design of the first filter screen, impurities automatically slide along the inclined surface of the filter screen into the first outer shell for collection under the impact of water flow, instead of accumulating on the surface of the filter screen. This increases the storage capacity of impurities, delays the filter screen clogging cycle, and reduces the frequency of manual cleaning.

This invention relates to the field of genetic engineering breeding technology, and discloses genes related to maize flowering period regulation, their expression products, haplotypes, and applications. The genes... ZmTL1, ZmHSP70-10, ZmMHF1 The nucleotide sequences are shown in SEQ ID NO.1, SEQ ID NO.3, and SEQ ID NO.5, and the amino acid sequences of the proteins they encode are shown in SEQ ID NO.2, SEQ ID NO.4, and SEQ ID NO.6. This invention also provides haplotypes of these genes. ZmZP1 The six haplotypes of a gene ZmHSP70-10 Two haplotypes of the gene ZmMHF1 Five haplotypes of the gene were identified. These genes, their expression products, and their haplotypes can be used to identify different tasseling, pollen shedding, and silking stages suitable for summer sowing in the Huang-Huai-Hai region. They also provide core gene resources for breeding new maize varieties resistant to extreme climates, significantly improving the precision of flowering time regulation and breeding efficiency, and have significant application value. The application methods can be extended to breeding practices for other flowering time-related regulatory genes.
