膜下滴灌马铃薯调亏灌溉的研究进展OA

The imbalance between supply and demand of water resources and the low utilization efficiency are major challenges in China's agricultural production.Adjusting deficit irrigation and mulched drip irrigation technology as water-saving irrigation methods have effectively improved water use efficiency in agriculture.This article reviews the research progress of regulated deficit irrigation in drip-irrigated potatoes under mulch,and discusses the impact of regulated deficit irrigation strategies on the physiological growth characteristics,yield,and quality of drip-irrigated potatoes under mulch.The results show that moderate deficit irrigation is beneficial for improving the water use efficiency of potatoes,promoting the growth of potato plants,and increasing crop yield and quality.Finally,the paper analyzes the current problems in the research of regulated deficit irrigation in drip-irrigated potatoes under mulch and puts forward countermeasures and suggestions.
