This invention relates to the field of plant genetic engineering technology, and more particularly to... SsNHX1 and SsSOS2 Dual-gene plant expression vector and its application in improving salt tolerance in alfalfa. The plant expression vector uses pCAMBIA1300 as its backbone and inserts genes derived from Suaeda salsa. SsNHX1 Genes and SsSOS2 It is constructed from genes. SsNHX1 Genes and SsSOS2 The CDS coding sequence of the gene is shown in SEQ ID NO:1 and SEQ ID NO:2 of the sequence listing. Using Agrobacterium tumefaciens EHA105-mediated transformation, the vector was introduced into the leaves of sterile alfalfa seedlings. Positive transgenic plants were obtained through co-culture, callus induction differentiation, and PCR identification. The advantage lies in the synergistic effect of the two genes, which effectively enhances the salt tolerance of alfalfa, enabling it to grow normally under 200–300 mM NaCl stress, providing a new solution for forage cultivation in saline soils.

This invention discloses a plant cultivation system, belonging to the technical field of plant cultivation systems. The system includes a cultivation chamber, double-sided supplemental lighting fixtures, multiple cultivation units, and a ventilation system. By centrally arranging double-sided supplemental lighting fixtures within a closed chamber, and layering multiple nutrient return components and multiple inclined cultivation pots on mounting frames on both sides of the fixtures, with the cultivation chambers of the pots inclined towards the supplemental lighting fixtures, and a ventilation system at the top of the chamber, all planting surfaces can receive uniform light and ventilation. Simultaneously, the ventilation system dissipates heat from the lighting fixtures, eliminating the need for additional cooling devices and resulting in lower energy consumption. Compared to traditional flat-layer cultivation, this solution offers higher space utilization efficiency, more efficient use of light resources, complete recycling of nutrient solution, and more uniform overall crop light exposure. Annual yield for the same planting area is significantly higher than traditional methods, while requiring less manpower and lower costs for daily maintenance, making it suitable for large-scale, high-efficiency cultivation.

This invention discloses a lactation-promoting composition containing a lime flavonoid extract, comprising, by weight, the following raw material components: 10-50 parts lime flavonoid extract, 5-30 parts synergistic active ingredients, and 20-85 parts excipients; wherein the lime flavonoid extract contains ≥80% total flavonoids (calculated as hesperidin), of which hesperidin ≥40%, neohesperidin ≥15%, naringin ≥10%, and hesperidin ≥5%. Using the lime flavonoid extract as the core, it achieves highly efficient lactation promotion through multi-target synergistic effects. In livestock applications, it can increase milk yield in dairy cows by 15%-28% and milk yield in sows by 20%-38%, while significantly improving milk fat, milk protein, and other milk nutritional indicators.
