The utilization of highly saline water in planting and vegetable growing in desert hinterland

Abstract

Locating in the Tarim Basin of Xinjiang, china, the Taklamakan Desert is an important replacement district of China oil industry development. In the Taklamakan Desert, climate is extreme arid, and rainfall quantity is below 50 mm. Though groundwater is plentiful, mineral content is higher. During the course of oil field base construction, with the exploitation of desert oil and natural gas resource we get success in planting and vegetable growing in use of highly saline water at the rate of 4 to 5 g/l. Highly saline water mainly contains Cl- and SO42-. The water shows a little alkaline (PH7-8). Greening plant selected includes sand-fixation shrubs, flowers and turf plants. The kinds of vegetable include tomato, celery, spinach and so on. Plants provide a material basis for almost 3000 (sometimes even 5000) oil works in desert oil field base to improve ecology environment. Meanwhile, it also provides fresh vegetable. Green plants offer living and inhabitation environment for other animals, too. In past there were only 35 kinds of wildlife (including insect). At present there are 57 kinds of animals. The quantity of microorganism as decomposer in vegetation systems also adds thousands of times.
