According to the geographical characteristics of mountains and rivers in this area, based on reality, with development as the theme, taking projects as the leading factor, gathering strength, highlighting key points, integrating resources, giving full play to advantages, and following the development idea of "regional economic characteristics, characteristic economic industrialization, and industrial economic scale", the Party Committee and the town government of Yongkang made scientific and effective adjustments to the single agricultural structure that used to focus on grain cultivation, and cultivated and strengthened the cultivation and breeding of vegetables and medlar in protected areas. The area of protected vegetables in the town is 172 1 mu, the planting area of Lycium barbarum is 1 198.4 mu, and the planting area of squeezed watermelon is 240 mu.
Yongkang Town put forward the slogan of "Efficient Demonstration Park" to promote "Efficient Economic Growth" and focus on the development of efficient park economy. First, Tanyang and Yongfeng two demonstration parks for facility vegetable planting have been built. The sunlight greenhouse in Yongkang Town started construction in 1989, and only one generation of sunlight greenhouse was built in 1999, covering an area of 160 mu. Faced with the situation of decentralized management, slow development and low efficiency, the town party Committee and government put forward the work requirements of emancipating the mind, sorting out ideas and seeking development. After four years' efforts, the town has built a solar greenhouse 1575 mu, and two science and technology demonstration parks, Tanyang and Yongfeng, with complete water circuit facilities, a seedling center, a field vegetable trading market and a vegetable circulation cooperative. Science, technology and information service organizations to promote the development of protected vegetables have basically taken shape. Now Tan Yang Vegetable Circulation Cooperative has realized a one-stop service system integrating seedling supply, information service, technical guidance and circulation sales, and its output value accounts for an increasing proportion of the total agricultural output value of the town. The output value of protected vegetables reached 8.25 million kilograms, with an output value of 9.9 million yuan, accounting for 6.5% of the total agricultural output value of the town, with per capita 196.8 yuan. ; The second is to start the construction of Caida Ecological Million Chicken Science and Technology Demonstration Park. In order to make the chicken industry bigger and stronger, the town party committee and the town government plan to build a demonstration park of ecological science and technology for millions of chickens in Caida Village of Yang Irrigation District within three years, taking advantage of its superior environment of dry terrain and good ventilation, its geographical advantages of being surrounded by mountains and rivers, wide coverage, no occupation of cultivated land, convenient infrastructure conditions and high enthusiasm of the people for raising chickens.
