Rhizosphere immunity: targeting the underground for sustainable plant health management

Zhong WEI, Ville-Petri FRIMAN, Thomas POMMIER, Stefan GEISEN, Alexandre JOUSSET, Qirong SHEN

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 3,   Pages 317-328 doi: 10.15302/J-FASE-2020346

Abstract:

Managing plant health is a great challenge for modern food production and is further complicated by the lack of common ground between the many disciplines involved in disease control. Here we present the concept of rhizosphere immunity, in which plant health is considered as an ecosystem level property emerging from networks of interactions between plants, microbiota and the surrounding soil matrix. These interactions can potentially extend the innate plant immune system to a point where the rhizosphere immunity can fulfil all four core functions of a full immune system: pathogen prevention, recognition, response and homeostasis. We suggest that considering plant health from a meta-organism perspective will help in developing multidisciplinary pathogen management strategies that focus on steering the whole plant-microbe-soil networks instead of individual components. This might be achieved by bringing together the latest discoveries in phytopathology, microbiome research, soil science and agronomy to pave the way toward more sustainable and productive agriculture.

Application of New Technology in Underground Engineering

Ma Hongqi

Strategic Study of CAE 2002, Volume 4, Issue 11,   Pages 37-41

Abstract:

Although the PD value of high-pressure manifold in Guangzhou Pumped-storage Project reaches 58 000 kN.m, the reinforcement concrete manifold is applied in the project instead of the conventional steel manifold. The design principle for such kind of manifold is based on bearing the water pressure mainly by the surrounding rock. Measures such as blasting control, concrete quality control and high-pressure grouting have been taken in construction to achieve the design requirement. The practice proves that this kind of manifold is reliable in performance, efficient in cost and excellent in benefit. Slipforming technology used in the concrete lining construction of high-pressure long inclined-shafts becomes the tough point, and no successful experience was available from both home and abroad at that time. Successful performance has been achieved in inclined-shaft construction of Guangzhou Pumped-storage Project by improving and bettering a set of interval inclined-shaft slipform imported. The self-innovated and patented XHM-7 inclined-shaft slipform equipment used in the long inclined-shaft construction of Tianhuangping Pumped-storage Project has realized the consecutive rising of the concrete lining in the inclined-shaft, which shows the advantages of novel structure, reliability, faster concreting and lower cost of the equipment. The successful application of the two above-mentioned new technologies will provide useful experiences to the promotion and application in the similar future projects.
