Experimental investigation on the effects of saline water drip irrigation on water use efficiency and quality of watermelons grown in saline soils;

But where there are large quantities of saline water and slightly salinized water, tests and practices show that the slightly salinized water of 2-3g/1 can be used; besides, under suitable conditions, the saline water of 4-6g/1 can be used as well.

Saline water irrigation effects were studied in a field experiment for three growing seasons with the aim of clarifying the characters of salt distribution and accumulation under surface drip irrigation and subsurface drip irrigation in arid region of Xinjiang.

The salt water hydrogeological characteristics and its exploration and utilization in the plain of North Henan;

However, there are lots of undeveloped shallow salt water resource in the region that are high mineralized water with poor quality.

It aims to find the appropriate amount of salt water drip irrigation for five different plants by determining their growth of main morphological indexes in different levels of salt water irrigation amount(3 000,4 500,6 000 m3·hm-2·a-1) at nursery in Yuli,Xinjiang,including height,ground diameter,crown width and root/shoot ratio.

Safety of winter wheat and soil using brackish water irrigation;

The model experiment adopted brackish water of four different mineralizations for farmland irrigation.

The purpose of developing the ecological mode aquiculture using the salt and low-salt water is to save the limited fresh water, adjust the structure of agriculture irrigation, and fully utilize the natural resources as salt,low-salt water and saline--alkaline waste land,sunlight and air,etc.

The compilation of the zoning plan for sewage control in Conghua City is based on the geographical condition and existing status of drainage, taking account of multiple factors such as the technology, economy and feasibility.
