THE 4C APPROACH AS A WAY TO UNDERSTAND SPECIES INTERACTIONS DETERMINING INTERCROPPING PRODUCTIVITY
《农业科学与工程前沿(英文)》 2021年 第8卷 第3期 页码 387-399 doi: 10.15302/J-FASE-2021414
Modern agriculture needs to develop transition pathways toward agroecological, resilient and sustainable farming systems. One key pathway for such agroecological intensification is the diversification of cropping systems using intercropping and notably cereal-grain legume mixtures. Such mixtures or intercrops have the potential to increase and stabilize yields and improve cereal grain protein concentration in comparison to sole crops. Species mixtures are complex and the 4C approach is both a pedagogical and scientific way to represent the combination of four joint effects of Competition, Complementarity, Cooperation, and Compensation as processes or effects occurring simultaneously and dynamically between species over the whole cropping cycle. Competition is when plants have fairly similar requirements for abiotic resources in space and time, the result of all processes that occur when one species has a greater ability to use limiting resources (e.g., nutrients, water, space, light) than others. Complementarity is when plants grown together have different requirements for abiotic resources in space, time or form. Cooperation is when the modification of the environment by one species is beneficial to the other(s). Compensation is when the failure of one species is compensated by the other(s) because they differ in their sensitivity to abiotic stress. The 4C approach allows to assess the performance of arable intercropping versus classical sole cropping through understanding the use of abiotic resources.

通过调控金属-载体界面间的电子传递提高催化性能已被证明是一种有效且具有挑战性的催化研究策略。本文提出了一种调变铂/碳纳米复合物催化剂中碳载体表面化学性质(载体表面吸电子/给电子含氧官能团),用以精细调控负载金属铂电子性质及其催化性能的方法。本文以氨硼烷水解制氢作为模型反应,结合密度泛函理论(DFT)计算、先进表征技术、动力学及同位素研究,定量关联了载体表面化学性质、铂电荷数与电子结合能、活化熵与活化焓,以及催化活性之间的关系。通过解耦碳载体表面复杂的影响因素,提出铂电荷数可作为实验易测量的催化活性描述符,其中通过铂电荷数的调变可使催化性能提升15倍。在此基础上,首次建立了包含催化剂活性描述符与活性位数量的介观动力学模型,可分别定量催化剂电子与几何效应,并预测催化性能的变化。本文提出的介观动力学模型可进一步用于设计与构筑高效的金属/碳催化剂。
