The application discloses a method for improving the growth and fruiting rate of 2-3-year-old Carya illinoensis container grafting seedlings after afforestation, which comprises the following steps: selecting 2-3-year-old Carya illinoensis container grafting seedlings and young seedling container seedlings, transplanting the container seedlings and the young seedling container seedlings into planting ponds in an afforestation area, setting up a wound on the stem bark of the container seedlings and the young seedling container seedlings respectively after scratching the stem bark, binding the wounds of the container seedlings and the young seedling container seedlings by using plastic cloth, filling soil, and normally maintaining; after the wounds are fully healed, the plastic cloth is removed, the part above the wound joint of the young seedling container seedlings is cut off, and the young seedling container seedlings are normally maintained until the roots of the young seedling container seedlings and the Carya illinoensis container seedlings are alive. The method can not only protect the root system of the container seedlings by the root system protection matrix, but also can release the root system winding, enhance the root system activity, and promote the rapid growth and development of the root system after transplanting.

This invention discloses an extract of *Prunus armeniaca* for treating prostatitis, its preparation method, and its application. Specifically, it relates to the fields of natural plant extraction and male urinary system pharmaceuticals. The *Prunus armeniaca* extract is prepared from the dried stem bark of *Prunus armeniaca*. On a dry weight basis, the extract contains at least 8.5% phytosterols and at least 12% fatty acids. This invention significantly improves the purity and extraction rate of phytosterols and fatty acids in the *Prunus armeniaca* extract by optimizing the extraction and purification process. It overcomes the bottlenecks of insufficient dissolution of active ingredients and high levels of impurities in traditional methods. Chromatographic detection ensures precise control and batch-to-batch stability of product quality. This naturally derived extract is highly safe and can be used alone or in combination with *Saw Palmetto* and pumpkin seed extracts. Through synergistic effects, it significantly enhances anti-inflammatory and prostate function-improving effects, providing a highly effective and safe new option for the treatment of prostatitis.

This invention relates to the field of novel compounds from the field of bald cypress, and provides an antitumor active compound, its preparation method, and its application. The antitumor active compound provided by this invention ( Taiwanin J This compound, a secondary metabolite of *Cephalotaxus fortunei*, belongs to the lignan class of compounds. Its antitumor activity enriches the diversity of lignan compounds and exhibits significant inhibitory activity against HeLa and A549 cells, showing broad application prospects in the preparation of antitumor drugs. Furthermore, it can serve as a lead compound, which is of great significance for the development of novel antitumor drugs. This invention also provides a method for preparing the antitumor active compound described above. The preparation method provided by this invention is simple to operate, low in cost, and easy to implement industrially. Moreover, this invention uses *Cephalotaxus fortunei* stem bark as raw material for extraction, achieving effective utilization of this rare plant resource, which aligns with the concepts of green environmental protection and a low-carbon economy.
