In order to make the seedlings survive easily, grow roots and maintain their original excellent characteristics, efficient propagation methods that can be used both in the laboratory and outdoors were studied. How to treat the seeds before sowing was investigated, which can make the seeds germinate better and the seedlings grow stronger. This is very important for artificial planting forests. This study also analyzed the ecological and economic value of the acacia tree, as well as the difficulties encountered during the cultivation process, and its role in protecting biodiversity and promoting sustainable agriculture. This research aims to enable better cultivation and utilization of acacia trees, which not only helps protect the ecological environment but also plays a role in industry.

They are of great value both in medicine and for making money. The two plants, the three-angled cypress and the wood-angled cypress, are frequently used in traditional medicine passed down from our ancestors and also have great potential in pharmaceutical factories. People value these plants because the fruits they bear contain a lot of saponins, which can be used to make natural cleansers and various things beneficial to the body (Singh et al., 2010; Asthana et al., 2011). Nowadays, many factories need these plants. Therefore, it has become particularly important to work out good propagation methods to ensure that the plant resources are always sufficient and to protect them well. The method of rapidly propagating plants is crucial for growing crops and trees, so as to meet the increasing demand for plants and grow large areas of forests more quickly. Methods such as rapid propagation and cutting propagation can grow many plants that meet the requirements at once, and also ensure that their varieties are pure and they all look similar (Yang, 2010; Asthana et al., 2011). For instance, the method of indoor reproduction enables plants to grow rapidly in a suitable environment, which is particularly important for disease-treating plants like acacia (Singh et al., 2010). Moreover, adjusting the reproductive conditions properly can make plants grow roots more easily and live better, which is crucial for successfully planting forests (Yang, 2010; Haider et al., 2016). This study will explore methods to make the young seedlings of the soapberry grow faster and be more resistant to diseases. This requires researching good methods for reproduction both indoors and outdoors, making it easy for seedlings to survive, grow roots, and retain their original good genes. This transaction study will also analyze how to handle seeds before sowing to make them germinate more easily and the seedlings grow stronger, so that the forest can be better planted. This research aims to ensure that seedless trees can be well cultivated and utilized all the time, which can not only protect them well but also provide raw materials for factories.
