Katsuragi Takeuchi
Scientific name: Pueraria montana (Lour.) Merr.
Common names: Genteng, Dagweng, Dried Ginger, Moringa
Family: Leguminaceae
Distribution:
Pueraria montana is widely distributed across China, except for Xinjiang and Tibet. It can be found throughout the country in various regions.
Growth Habits:
This plant thrives in warm, moist environments and is also resistant to cold, drought, and poor soil conditions. It commonly grows in grasslands, shrublands, sparse forests, and forest edges. Its root system is well-developed, giving it strong vitality and adaptability.
Use of PuTuo (Kudzu):
The use of wild kudzu in China dates back many years, but large-scale artificial cultivation has only become prominent in recent decades. In 1995, Zhejiang Forestry College took the lead in researching and developing techniques for cultivating non-imposable woodland Pueraria lucidum. Under the leadership of Professor Lou Lunhuan, the research team traveled to Guangdong, Fujian, Jiangxi, Anhui, and Zhejiang to collect wild vine seedlings. After extensive selection and cultivation trials, four high-quality varieties of Pueraria lucidum were successfully developed—each with fast growth, high powder extraction rates, and ease of manual cultivation. This breakthrough made large-scale artificial cultivation of wild Kudzu feasible, offering a new path for agricultural efficiency and increasing farmers' income.
The economic value and development potential of Kudzu have attracted growing attention, including from Song Diquan, who previously ran a pharmaceutical and bottle-capping business. Intrigued by the opportunities, he decided to invest in this promising crop.
In April 2002, Song purchased 20 mu of high-quality Pueraria seedlings from Zhejiang Forestry College and was pleasantly surprised by the success of his initial efforts. Encouraged by this, he later contracted 300 mu of barren hills in his hometown village of Kejia. He also subcontracted a 200-mu kudzu base in Yiyang Village, Changhua Town, to begin large-scale artificial planting. However, to generate real profit, the kudzu needed to be processed into Pueraria powder. At the time, there were no professional processing companies in Zhejiang, so Song planned to establish a processing plant.
In 2003, after approval from the city's Science and Technology Bureau, Song partnered with Professor Lou to form a joint venture between academia and industry. Together, they embarked on research into the processing of Pueraria powder. From designing and developing machinery to installation and commissioning, the team faced numerous challenges. Eventually, they created specialized equipment capable of processing 5 tons of Pueraria per day. Once the arrowroot powder was successfully extracted, Song didn't stop there. He learned that Chinese instant foods struggled in European and American markets because they required boiling water, which is not common in those regions. Inspired by this, he spent over two months experimenting and finally developed a cold-water soluble arrowroot powder, filling a domestic gap.
At the Changhua Base, we saw that the kudzu plants grown in May last year are now larger than hot water bottles. It is expected that the yield per mu will reach 7.5 tons next year. With Song Diquan's 300-mu production base, a total of 2,250 tons of Pueraria could be harvested. Based on a ratio of 1 ton of flour per 5 tons of raw material, this could produce over 450 tons of Pueraria flour, generating an output value of more than 135 million yuan. Currently, the city has planted over 600 acres of kudzu, and many farmers are eager to start planting as well. The Municipal Science and Technology Bureau has also launched a plan to cultivate 2,000 acres of kudzu in the near future.
Smart Cylinder Locks represent the latest advancement in security technology, combining traditional mechanical locking mechanisms with cutting-edge digital features to provide enhanced convenience, safety, and control. Designed to replace or retrofit existing cylinder locks on doors, cabinets, or safes, these smart locks offer users a seamless way to manage access without the need for physical keys. Utilizing Bluetooth, Wi-Fi, RFID, or biometric technologies such as fingerprint recognition, smart cylinder locks enable keyless entry that can be controlled remotely via smartphone apps or integrated with home automation systems.
The key benefits of smart cylinder locks include enhanced security protocols such as real-time access logs, temporary or scheduled user permissions, and tamper alarms that alert owners to unauthorized attempts. Many models feature encrypted communication and fail-safe mechanical override options to ensure that security is never compromised. Installation is typically straightforward and requires minimal modification to existing door hardware, making smart cylinder locks an ideal choice for residential homes, commercial offices, and institutional facilities alike.
In addition to their robust security features, smart cylinder locks offer unmatched convenience and flexibility. Users can grant access to family members, guests, or maintenance personnel remotely and revoke permissions instantly when needed. Integration with voice assistants and smart home ecosystems allows for seamless operation through voice commands or automated routines. Battery-powered designs ensure operation even during power outages, and low-battery alerts help maintain uninterrupted security.
Smart cylinder locks come in a variety of designs and finishes to match different door types and aesthetics, including brass, stainless steel, and matte black. They are also engineered to meet industry standards for durability and weather resistance, ensuring reliable performance both indoors and outdoors. Whether upgrading a single entry point or outfitting an entire building, smart cylinder locks deliver a future-ready security solution that combines advanced technology with user-friendly functionality.
