In order to implement the decision of the CPC Central Committee and the State Council on the key development of oil crops in the "14th Five-Year Plan", Jiangmen Taishan, with the technical support of the team of President Li Yongtao from the College of Resources and Environment of South China Agricultural University, made full use of the agricultural ecological, high-value and landscape functional characteristics of oil sunflower, developed oil sunflower as a characteristic oil crop in abandoned land and saline-alkali land according to local conditions, and vigorously implemented oil production capacity without competing with food crops.
Jiangmen Xincan Ecological Technology Co., Ltd. has planted 30 mu of oil sunflower in the abandoned land in Chonglou Town, Taishan, Jiangmen since February, 2022. Using the characteristics of low cost of oil sunflower planting management as a resource-saving crop, the abandoned land has been re-cultivated, effectively improving the land utilization rate and agricultural production efficiency. At present, the abandoned land in Chonglou Town is in full bloom, with golden flowers and seas, attracting tourists for sightseeing.

Taishan Haojiafeng Technology Co., Ltd. has planted more than 100 mu of oil sunflower in the saline-alkali land of Haiyan Town, Taishan, Jiangmen since March 2022, and it is expected to plant nearly 300 mu. Using the high stress resistance, salt absorption and potassium enrichment of oil sunflower, ecological restoration of saline-alkali land was carried out and efficient agricultural utilization was realized. Oil sunflower has adjustable period and bright color, which not only realizes the efficient utilization of winter fallow land, abandoned land and saline-alkali land, but also achieves the landscape effect, promotes the integration of agriculture and tourism, and helps the ecological environment construction and the revitalization of beautiful countryside.
