工程农业技术的设计范例
Model design of EAT
    我把第 16 方案作为应用工程农业技术的范例。它是以天山南麓为背景,模拟在恶劣的条件下从事农业生产呼活动。人造耕地选在向阳 45 度的山坡上,试验区内没有天然土壤,年降水量不足 200 毫米 ,昼夜温差大,日光充足。应用工程农业技术修建 100 厘米 深的梯田槽基,在槽基下面开凿蓄水室,该蓄水室又与试验区内的集水区相连通,形成完善的大气降水保存体系。然后在梯田槽基内填充 100 厘米 厚的人造土壤,这就是人造耕地。为了防止农田水分蒸发,在人造耕地上建有塑料大棚或者玻璃屋。为防止土壤盐渍化还应当采用毛细渗灌技术。该试验区每当雨季天下雨(雪)时,山上产生径流,集水区的水可以流到蓄水室内,每亩耕地可以蓄水 695 立方米 ,相当于 1041 毫米 的年降水量,用来灌溉农田和人畜用水。整个试验区变成一个良性的循环体系,人造耕地上生长的粮食、饲料及其它农产品,可以供区内人畜食用或者对外出售。人畜大小便及秸秆送到工厂造土,工厂产生的沼气又返回试验区作燃料。由于不大量使用化肥和农药(最好一点也不使用)和没有工业污染,生活污水只需适当处理就可以重新使用,实现小范围内人与自然的和谐统一。
 
工程农业技术的设计范例
Model design of EAT

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.
