在空闲拱棚和黄瓜日光温室内,分别研究了化学反应法(H2SO4+NH4HCO3)、煤球燃烧法和颗粒CO2气肥3种肥源的性能,并与液体CO2进行成本比较,结果表明:化学反应法产气迅速,设备折旧成本较低;煤球燃烧法产气速度中等,原料成本最低;颗粒CO2气肥产气速度较慢且不易调控,原料成本最高。考虑化学反应产物的再利用因素,化学反应法、煤球燃烧法和液体CO2 3种肥源总成本接近,但从生态、节能、成本和效果等方面综合评价,煤球燃烧法原料丰富、成本低廉,较符合我国目前的设施、经济、资源和技术条件。
在空閒拱棚和黃瓜日光溫室內,分彆研究瞭化學反應法(H2SO4+NH4HCO3)、煤毬燃燒法和顆粒CO2氣肥3種肥源的性能,併與液體CO2進行成本比較,結果錶明:化學反應法產氣迅速,設備摺舊成本較低;煤毬燃燒法產氣速度中等,原料成本最低;顆粒CO2氣肥產氣速度較慢且不易調控,原料成本最高。攷慮化學反應產物的再利用因素,化學反應法、煤毬燃燒法和液體CO2 3種肥源總成本接近,但從生態、節能、成本和效果等方麵綜閤評價,煤毬燃燒法原料豐富、成本低廉,較符閤我國目前的設施、經濟、資源和技術條件。

Three methods for CO2 enrichment-chemical reaction(H2SO4+NH4HCO3), briquet combustion, granular CO2 fertilizer were comparatively studied in free tunnels and solar greenhouses for cucumber cultivation, and the yearly total cost of different methods(including pure liquid CO2) were compared. Chemical reaction had higher CO2 releasing velocity and relatively lower equipment depreciation charge; honeycomb briquet combustion produced CO2 at moderate rate, and the raw material cost was the least; granular CO2 fertilizer having highest raw material cost released CO2 slowest. When the re-use of by-product of chemical reaction was concerned, annual cost of chemical reaction was similar with that of briquet combustion and liquid CO2. Comprehensively evaluated from viewpoints of ecology, energy-saving, cost and effect, briquet combustion was in more accordance with the present situations in China including facility type, economic situation, resource condition and technique level, and so on.
