Our objective is to engage in the selective breeding of crucial vegetable crops in the Yilan region, as well as improve cultivation techniques for these crops.
Key assignments involved the breeding of green onions, tomatoes, and aquatic vegetables. We have successfully bred high-quality heat-tolerant green onion varieties such as ‘Lanyang No. 1’, Futsun- ‘Lanyang No. 3’, and ‘Lanyang No. 4’. Besides, we have also bred heat- tolerant and disease-resistant tomato varieties such as ‘Hualien Asveg No. 5’, ‘Hualien Asveg No. 13’, ‘Hualien Asveg No. 14’, ‘Hualien Asveg No. 17’, ‘Hualien Asveg No. 18’, and ‘Hualien Asveg No. 21’.
We promoted the green onion health management and production system by combining rational fertilization, virus-free seedlings, and integrated disease and pest prevention and control methods to achieve the goals of safe high-quality green onion production, and reduced chemicals use. In addition, we established environmentally friendly tillage systems suitable for the Yilan region by performing crop rotation experiments on green onions and rice, and conducted field investigations of Xingjian organic village that engaged in rice–green onion crop rotations, from which we determined that the number of types of insects and frogs were 2-6 times higher than those in conventional cultivation areas.
Because of Yilan region’s rainy and humid environment, and to increase the region’s vegetable diversity, we developed aquatic plants that feature high resistance to harsh growing environments and low chemicals demands, such as watercress (Nasturium officinale) to be novel vegetables. In addition, we developed the effective method that can doubly prolong under-water display lives of three popular ornamental aquatics— purple waffle plant (Hemigraphis alternata cv. ‘Exotica’), blue water hyssop (Bacopa carolineana) and giant bacopa (Bacopa lanigera). This method has transferred to associated growers. Furthermore, we researched and developed unique and symbiotic cultivation models for the agriculture and fishing industries, inventing an organic water bamboo cultivation technique called “fish-water bamboo symbiosis.” This endeavor successfully created an organic agricultural industry that featured unique local characteristics, increasing product value by over 100%.
