Superior varieties of rubber trees are crucial elements in achieving stable production and supply of natural rubber. In China, rubber tree planting areas are situated at the northern edga of the world’s tropical zone and thus belong to non-traditional rubber tree planting areas with climatic conditions inferior to the traditional ones in Southeast Asia. The planted rubber trees are frequently damaged by low temperatures and diseases. Therefore, an urgent need in natural rubber production is to develop varieties with highyield potential and strong stress-tolerance. The scarcity of such varieties is mainly ascribed to the highly heterozygous genome, a long juvenile …

Food security is a top priority in national governance. Since 1949, high-standard farmland construction, agricultural mechanization development, and agricultural technology promotion have all contributed to the grain production. To ensure grain security, China has drawn a “red line” of 1.8 billion mu (about 120 million hectares) as the official minimum of arable land. At the same time, increasing the investment of capital goods such as fertilizer and pesticides can no longer produce more food. Due to the extensive farming method in the past, the continuous increase in total grain output becomes difficult in the future. With the rapid development of …

Biotech seed industry is a strategic core industry. Biotechnology combined with digital technology has promoted the seed industry into an intelligent era, and the breeding paradigm has changed from “experimental selection” to “computational selection”. Biotech seed industry has become a research and development intensive industry, and the market is highly concentrated, which is controlled by large multinational enterprises. The scientific and technological output of China and the United States is in the first echelon, and the number of papers and authorized patents ranks among the top two in the world. From the perspective of core competitiveness, the United States is …
Industrialization Of Tall Wheatgrass For Construction Of “Coastal Grass Belt”, Hongwei Li, Qi Zheng, Jianlin Wang, Hongyong Sun, Kexin Zhang, Hongman Fang, Xuerong Xing, Weicai Yang, Xiaofeng Cao, Xiaojing Liu, Haichun Jing, Kang Chong, Zhensheng Li

Bulletin of Chinese Academy of Sciences (Chinese Version)
Tall wheatgrass (Elytrigia elongata) is a perennial cool-season bunchgrass with high productivity and tolerance to salt and alkali, waterlogging, and drought. Since first introduced into China in 1950s, tall wheatgrass has long been used as a wild parent for distant hybridization with wheat (Triticum aestivum). During 1980s─1990s, a few tall wheatgrass varieties were introduced to China as forage grass, nonetheless, currently they are still not widely cultivated and no variety was certificated. In 2020, Zhensheng Li put forward a proposal to construct “Coastal Grass Belt” on saline and alkaline soils in the Circum-Bohai sea region, which provides an opportunity for …

The blue carbon function and carbon sequestration potential of coastal ecosystems, such as salt marshes, mangroves and seagrass beds, have emerged as one of the long-term solutions to mitigate global climate change. However, the blue carbon sequestration technology has been neglected in most ecological protection and restoration projects of coastal ecosystems. Besides, in the process of project implementation and management, the dynamic monitoring and systematic evaluation of carbon sink are imperfect. This study proposes the concept of enhancement of coastal blue carbon, focusing on four key technologies of soil carbon emission reduction technology, plant carbon sequestration technology, soil microbial carbon …

Bulletin of Chinese Academy of Sciences (Chinese Version)
Under the new situation, expanding and strengthening the crop seed industry and ensuring food security have been elevated to the national strategic importance. It urgently needs to improve the crop seed national innovation system and promote the deep integration of the innovation chain and industrial chain. The crop seed industry in developed countries such as the United States has formed a relatively mature industrial innovation system dominated by enterprises; however, China's crop seed industry innovation system is large but weak, the seed industry innovation efficiency is low, and the innovation ecology of the innovation chain and the industrial chain integration …

Not only the grain rations must be secured absolutely in China, but also the feed grains. However, the limited arable land resource in China determines that grass planting shall not "compete for land with staple food". Planting high quality salt-tolerant forage grass on the saline wasteland and developing animal husbandry production can not only meet the demand of increasing proportion of animal protein in Chinese diet structure, but more importantly, it can help to solve the problems of insufficient forage planting and import over-dependence. Hence it plays an important role in guaranteeing national food security. Therefore, it is necessary to …
