概括

国家耕地改善计划 (NCLIP) 显著提高了中国的农业生产力. 虽然最初的收益依赖于投入,但土壤肥力在2000年后成为关键,突出了可持续农业的发展战略.

科学领域:

农业科学农业科学
环境科学环境科学
农业生态系统管理管理

背景情况:

耕地生产率 (CLP) 对粮食安全和环境可持续性至关重要.
中国的黄海海平原已经经历了30多年的国家耕地改善计划 (NCLIP).
了解NCLIP的贡献和改变驱动因素对于可持续农业至关重要.

研究的目的:

量化NCLIP对CLP改进的贡献.
在过去的三十年中,确定了CLP增强的变化决定因素.
为可持续农业提供信息的农业生态系统管理.

主要方法:

Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
