长效专用控释肥在受控生态生保系统中应用的实验研究

Experimental Study of Special Long-effect Controlled-releasing Fertilizers in Controlled Ecological Life Support System.

目的研究并验证长效专用控释肥料在受控生态生保系统中应用的可行性,为未来受控生态生保系统中高等植物的栽培提供合适的养分资源。方法在特定的光照、温度和大气等环境条件下,通过植物栽培实验,进行施肥、不施肥以及不同专用控释肥料品种的生菜培养,比较不同处理下植株的生长形态、测试并分析植株体内的各种营养组分等。结果在不施肥的条件下,植株不能正常生长,施肥能促进植株的正常生长发育;利用肥料1栽培的生菜植株品质好于肥料2栽培的生菜植株。结论所研制的长效控释专用肥料能在受控生态生保系统中应用,针对不同的植物品种应选用不同的肥料品种作为养分资源。

Objective To study thee possibility of＇using the special long-effect controlled-releasing fertilizer （SLECRF） for plant growing in the Controlled Ecological Life Support System （CELSS）. Method Under conditions of controlled illumination, temperature, and atmosphere, planting of Lettuce in the pots was carried out, the experiment included groups of control （ no fertilization）, fertilizer 1 （No. 1） and fertilizer 2 （No. 2）. Result The plants with no fertilizer grew abnormally, the fertilizer could promote the plants＇ developing, and growing. The quality of plants grown with fertilizer 1 was better than those grown with fertilizer 2. Conclusion The SLECRF can be used as nutrient sources for high plants grown in the CELSS, and different kinds of fertilizer should be used for different kinds of the plants.
