I will take the NO.16 pilot test program as a model for the application of EAT. The program is a typical one set at the southern foothill of Mount Tianshan as its background, simulating agricultural activities under extreme adverse natural conditions. The artificial land is chosen to be on the slope with a 45 ° angle exposed to the sun. The test area is covered with almost no natural soil and its annual precipitation is less than 200 mm. The temperature is high with enough sunlight and big temperature difference between day and night. According to the artificial land design program, engineering agricultural technique will be used to build a 100 cm deep trough base of terraced fields. Then dig a water storage chest below the trough base. The water storage chest is connected with the gathering ground in the test area, forming a perfect precipitation conservation system. Fill 100 cm thick artificial soil into the trough base of the terraced fields, thus the artificial cultivated land comes into being. To prevent the evaporization of moisture from the fields, plastic sheds or glass sheds will be built on the artificial land. To prevent the salinization of the soil, capillary percolation technique shall be used. When it rains or snows, ground runoffs will be formed on the mountain and the water in the gathering ground will flow to the water storage chest below the artificial land. It is designed in the program that 695 m 3 water can be stored under every mu of artificial land, equivalent of 1041 mm annual precipitation, which can be used for irrigatation and as drinking water for humans and animals. A favorable cyclic system will be established in the whole test area with the crops, feed crops and other farm produce growing on the artificial land, which can be used by the people and animals in the test area or sold elsewhere. The waste of humans and animals as well as straw will be sent to the factory to make soil and the methane produced from the factory will be used as fuel in the test area. Because not much chemical fertilizer or pesticide is used (It is most desirable that no chemical fertilizer or pesticide is used) nor industrial pollution exists, domestic waste water can be reused after reasonable treatment, realizing the harmonious unity between human and nature in a limited area.
