文摘

•: Rain-fed potato fields were a CH₄ sink.
•: Increased nitrogen fertilisation and temperature led to higher CH₄ absorption.
•: CH₄ oxidation capacity showed a parabolic trend with soil moisture increased.
•: Crop rotation increased CH₄ absorption one time higher than continuous cropping.
•: A mechanism concept model of the CH₄ exchange in potato fields was advanced.
