The Chinese water administration department has continuously explored and formulated regulatory market-oriented control policies to alleviate the contradiction between shortage economic social development promote new idea of ‘water-saving first’ control. Among them, implementing a resources tax policy as price means achieved initial success. water-saving effect collection is one important bases...

Using x-ray scattering measurements we have quantitatively determined the effect of poloxamer 188 (P188), a polymer known to seal damaged membranes, on the structure of lipid monolayers. P188 selectively inserts into low lipid-density regions of the membrane and "corrals" lipid molecules to pack tightly, leading to unexpected Bragg peaks at low nominal lipid density and inducing lipid/poloxamer...

Plastic mulching with drip irrigation is a new water-saving rice cultivation technology, but little is known on its productivity and water-saving capacity. This study aimed to assess the production potential, performance, and water use efficiency (WUE) of rice under plastic mulching with drip irrigation. Field experiments were conducted over 2 years with two rice cultivars under different culti...

The use of rootstocks and clones with different vigor sensitivity to water deficit is an important useful agronomic tool for vineyard management. It essential search systems strategies that maximize efficiency productivity in the water. objective this work was carry out a comparative economic environmental evaluation, using life cycle cost (LCC) assessment (LCA) methodology, organic cultivation...

abstract this study was conducted to determine the best drip irrigation method for pepper cultivation with the objective of water saving and obtaining maximum yield. the study was done during two years. experimental design was randomized complete blocks design (rcbd) in split plot with four replications. three different drip irrigation methods; drip irrigation with in-line emitter tubes, drip i...

the optimal allocation of the chahnimeh water resources among different sectors, viz. domestic, agricultural and environmental consumptions, was determined using the goal programming method in gams, based on the present condition in the area. results showed an increase of 15.4, 44.5 and 230% in allocation of water to domestic, agriculture and environment sectors, respectively, in this method as...

To develop an optimal irrigation and fertilization system for Korla fragrant pear in the Xinjiang region, effects of water fertilizer coupling on quality, yield, use efficiency (IWUE), partial productivity (PFP), net profits under condition limited drip were studied through field experiments by combining multiple regression analysis spatial analysis. A comprehensive quality evaluation model was...

Due to the frequent drought periods, water consumption increase, and competition of different water-using sectors, the Hirmand catchment is in a critical water status in the Sistan region. This threat has been intensified in recent years. To cope with this problem, we must pay more attention to different types of water use such as virtual water as a water saving method. The present study calcul...
