The dynamic and static deficit (DDI, SDI), partial root drying (DPRD, SPRD) and full (FI)irrigation strategies were applied in Agria and Ramos potato cultivars in a semi-arid area. FIreceived 100% of the potential evapotranspiration (ET); SDI and SPRD received 75% of ETduring the growth period; DDI and DPRD received 90% of ET in the first third, 75% of ET inthe second third and 50% of ET in the...

Available fresh water resources are subjected to an ever-increasing pressure due to extensive agricultural water demand for irrigated lands. A long-term perspective in shortage of fresh water resources, especially in arid and semi-arid area, highlights an urgent solution for innovative irrigation strategy and agricultural water management. This paper is a review on the wide applications of the ...

The Pearl River Delta (PRD) region in South China is one of the most economically developed regions in China, but it is also noted for its severe air pollution due to industrial/metropolitan emissions. In order to continuously improve the understanding and quantification of air pollution in this region, an intensive campaign was executed in PRD during October–November 2008. Here, we report and ...

Changes in the plant water status, biochemical and hormonal responses, were investigated three olive cultivars (Arbequina, Arbosana Chetoui) grown a super-high-density orchard under partial root-zone drying (PRD) irrigation. Four irrigation treatments applied during two growing seasons (2015 2016); control treatment (100 % ETc) irrigated at 100 of crop evapotranspiration on both parts PRD PRD, ...

Abstract. Using a new high-resolution air quality reanalysis dataset for China five winters from December 2013 to February 2018, we examine the influence of large-scale circulation on daily PM2.5 variability through its direct effect key regional meteorological variables over three major populated regions China: Beijing–Tianjin–Hebei (BTH), Yangtze River Delta (YRD) and Pearl (PRD). In BTH, sha...
