water shortages within the western USA are resulting in the adoption of water-saving agricultural practices within this region. Among the many possible methods for saving water in agriculture, the adoption of subsurface drip irrigation （SDI） provides a potential solution to the problem of low water use efficiency. Other advantages of SDI include reduced NO3 leaching compared to surface irrigation, higher yields, a dry soil surface for improved weed control, better crop health, and harvest flexibility for many specialty crops. The use of SDI also allows the virtual elimination of crop water stress, the ability to apply water and nutrients to the most active part of the root zone, protection of drip lines from damage due to cultivation and tillage, and the ability to irrigate with wastewater while preventing human contact. Yet, SDI is used only on a minority of cropland in the arid western USA. Reasons for the limited adoption of SDI include the high initial capital investment required, the need for intensive management, and the urbanization that is rapidly consuming farmland in parts of the western USA. The contributions of SDI to increasing yield, quality, and water use efficiency have been demonstrated. The two major barriers to SDI sustainability in arid regions are economics （i.e., paying for the SDI system）, including the high cost of installation; and salt accumulation, which requires periodic leaching, specialized tillage methods, or transplanting of seedlings rather than direct-seeding. We will review advances in irrigation management with SDI.

water-saving agriculture:An Urgent Issue

Journal of Integrative Plant Biology 2007年第10期49卷 1409-1409页

The twentieth century has witnessed the great effort of mankind to strive for more food production, which has led to an unprecedented increase in grain production known as the First Green Revolution. As mankind entered the 21st century, the Blue Revolution -the struggle in agriculture for better use of water resources - has just begun. Norman E. Borlaug, 1970 Nobel Peace Prize Laureate, said in 2000, “how can we continue to expand food production for a growing world population within the parameters of likely water availability？ The inevitable conclusion is that humankind in the 21st Century will need to bring about a ＇Blue Revolution - more crop for every drop＇ to complement the ＇Green Revolution＇ of the 20th Century. water use productivity must be wedded to land use productivity. Science and technology will be called upon to show the way”.

A Review on water-saving agriculture in Europe

引用

Journal of water Resource and Protection 2022年第4期14卷 305-317页

作者： Shan Zhang Xiujuan Wang Lingshan Zhou College of Public Adminisatration Shandong Agricultural University Tai’an China

This paper aims to analyze the research on the current situation of water-saving agriculture development in Europe. water-saving agriculture in Europe started early, governments and farmers in various countries have a strong awareness of water-saving in agriculture and have achieved certain results. Due to the global spread of the COVID-19 pandemic, the lack of up-to-date field research, the complexity of various agricultural disciplines and categories, and the lack of information sharing, the current cognition of recent progress in the development of water-saving agriculture in Europe is not comprehensive enough. This paper selects four representative European countries: Spain, Germany, Italy, and Denmark as the research objects. Based on the existing research of Chinese and Western scholars, this paper analyzes and studies the current situation of water-saving agriculture in Europe. It has far-reaching significance for other countries in the world to have further development in water-saving agriculture and to protect water resources.

Effects of Continuous Plastic Film Mulching on Soil Bacterial Diversity, Organic Matter and Rice water Use Efficiency

引用

Journal of Geoscience and Environment Protection 2016年第4期4卷 1-6页

作者： Meiyan Wu Ruochao Hao Lianghuan Wu Engineering Research Center of Wetland agriculture in the Middle Reaches of the Yangtze River Ministry of Education Hubei Provincial Key Discipline of Crop Science Yangtze University Jingzhou China Zhejiang Provincial Key Laboratory of Subtropical Soil and Plant Nutrition College of Environmental and Resource Sciences Zhejiang University Hangzhou China

Two field experiments were conducted to study the effects of 6-year plastic film mulching on bacterial diversity, organic matter of paddy soil and water use efficiency on different soils with great environmental variabilities in Zhejiang Province, China, under non-flooding condition. The experiment started in 2001 at two sites with one rice crop annually. Three treatments included plastic film mulching with no flooding (PM), no plastic film mulching and no flooding (UM), and traditional flooding management (TF). Soil samples were collected and analyzed for bacterial diversity by DGGE and organic matter content, and water use efficiency (WUE) was calculated. The results showed that PM treatment favored the development of a more total bacterial community compared with TF management, the total number of bands was 33.3, 31.7 at tiller stage and heading stage (p water use efficiency were increased significantly by 70.2% - 80.4% and 273.7% - 1300.0% for PM. It is essential to develop the water-saving agriculture.
