温度胁迫对农作物和入侵杂草的生长影响机制

Effect Mechanistic of Temperature Stress on Growth of Crops and Invasive Weeds

在全球气候变化的背景下,我国极端气候出现的次数比以往更加频繁,而极端的高温或低温气候都对农作物的生长发育有负面影响,严重影响了我国农作物的产量。温度的改变加快了入侵杂草的迁移和演替,农田系统中的入侵杂草和农作物竞争资源并在竞争中获得优势,最终对农业生产造成极大的威胁和危害。本文综述了温度胁迫对农作物和入侵杂草生长的影响,并阐述了在温度改变背景下农作物系统可能面临的困境,最后展望了未来在温度变化背景下的农作物-杂草系统相关研究的方向。

In the context of global climate change,the frequency of extreme climate in China is more frequent than before,and the extreme high temperature or low temperature climate negatively impacts on the growth and development of crops,and seriously affectes their yield.The change in climate temperature accelerates the migration and succession of invasive weeds which compete with crops for resources and usually gain advantages in farming systems.It ultimately poses a great threat and harm to agricultural production.This paper reviewed the effects of temperature stress on the growth of crops and invasive weeds,and described the possible dilemmas faced by crop systems,and finally looked into future directions for research related to crop-weed systems under the context of climate temperature change.
