In the first year, the proposed system in which the greenhouse gases generated in the composting process were trapped and they were used for crop cultivation was designed. Algae was cultivated With the nutrient in which ammonia generated in the composting process was solved. In the second year, the proposed system was tested for its effect and usefulness.The gas component and concentration generated in the composting process were measured and the use of carbon dioxide, main component, was discussed. The sensor of C0_2 and NH_3 were installed at the outlet of the composting machine to measure their concentration cotinuously. The cattle manure 14kg, sawdust 1.5kg and the ferment seed manure 0.5kg were used as the experimental materials. C0_2 and NH_3 gas were generated from the start of composting process and the total emission were 576g and 6.4g respectively. A water hyacinth was used as testing crop for assimilation of C0_2. The gas discharged from the composting machine was sent to the crop culture chamber through the soil deodorizer. 30 pieces of water hyacinth were cultivated in three chamber of 0.64m2 and they assimilate 97g CO_2 for 15 days. Utilization of C0_2 with mini tomato cultivation was tested in a small size greenhouse. The gas generated in composting process was used for atmosphere of tomato cultivation. The result was not significant because the tested tomato took a disease in the way of cultivation.

在第一年，设计了一个拟议的系统，其中收集了堆肥过程中产生的温室气体，并将其用于作物种植。利用分解堆肥过程中产生的氨的养分培养藻类。在第二年，对该系统的效果和实用性进行了测试，测量了堆肥过程中产生的气体成分和浓度，并讨论了主要成分二氧化碳的使用。在堆肥机的出口处安装了CO_2和NH_3传感器，连续测量其浓度。以牛粪14kg、锯末1.5kg、发酵种肥0.5kg为试验材料。堆肥过程开始时产生CO_2和NH_3气体，总排放量分别为576g和6.4g。以凤眼莲为供试作物，研究了其CO_2吸收特性。从堆肥机排出的气体通过土壤净化器被送到作物培养室。在三个0.64m2的温室中培养30株水葫芦，吸收97gCO_2，培养15d。在小型温室中进行了小型番茄栽培CO_2利用试验。利用堆肥过程中产生的气体作为番茄栽培的气调。由于供试番茄在栽培过程中发生了病害，因此试验结果不显著。
