Professor Chen Guangyu, who has been engaged in bioengineering research and study in the United States and New Zealand for many years, returned to China in 1997 and began to study asparagus breeding. Under his leadership, the researchers of Jiangxi Academy of Agricultural Sciences bred the first clonal hybrid Jinggang 701 with completely independent intellectual property rights in 2007, and in 2008, the first new tetraploid purple asparagus variety Jinggang Hong in China, which broke the situation that foreign varieties were outstanding. He said that breeding domestic asparagus varieties can reduce the cost of production, sales and export of domestic asparagus, and enhance China's competitiveness in the international market.
Speaking about the international asparagus symposium, Chen Guangyu said that through this academic discussion, "we also see the gap between domestic asparagus industry and foreign countries". He pointed out that although China is the world's largest asparagus producer and has cultivated domestic asparagus varieties, it does not have a voice in the international market and accounts for a small proportion of the world's asparagus trade. The main reason is that China has not yet established a breeding system for asparagus, and the varieties planted are relatively single. Although Peru does not have a breeding system, it has invested a lot of research from production to marketing to export, which is worth learning from China.
Chen Guangyu believes that the development of asparagus cultivation in China can become a new growth point for the development of local economy and is a promising foreign exchange agricultural project.
Artificial cultivation of Asparagus in China began in the late Qing Dynasty and early Republic of China, and was introduced by foreign missionaries. At first, only around Shanghai and Tianjin were tested, and the area was limited. Around 1932, Taiwan.
Asparagus has also been planted in Gulf Province. In 1956, Taiwan Province began to produce canned asparagus in Changhua County. Successful trial sales in Hong Kong and other markets prompted the rapid expansion of cultivation area of Asparagus in Taiwan Province. By 1965, the cultivation area reached 18,000 hectares, and more than 100 canned processing plants were established. The canned asparagus produced was sold all over the world. Its export volume once leaped to the first place in the world, and Taiwan gained a huge foreign exchange income. People.
China mainland introduced and developed asparagus in Yangzhou area of Jiangsu Province in 1966. Yangzhou Cannery began trial production of canned asparagus in 1968-1969. After the 1970s, the foreign trade department introduced a batch of asparagus seeds to be planted in Zhejiang, Henan and Shandong provinces. It has developed successively in Zhoukou, Xinyang, Xuchang, Hangzhou, Fuyang, Ninghai, Anqiu, Caoxian and Linyi of Henan Province and exported canned asparagus since 1976. At present, the cultivation of asparagus has not been reported in Tibet and Qinghai, but in other provinces, with an area of 100,000 hectares at most. Among them, Shandong, Shanxi, Hebei, Zhejiang, Jiangsu, Fujian and Sichuan have larger cultivation areas. The largest cultivated areas are Cao, Shan, Anqiu, Lijin, Yingxian and Xuxian in Shandong, Yongji and Houma in Shanxi, Fuyang in Zhejiang, Dongshan in Fujian and Fengxian in Jiangsu, Nangong, Weixian and Rongcheng in Hebei.
