Abstract

This research investigated the feasibility of witloof chicory production with fermentation heat of cow’s manure, in Hokkaido, during semi-cold and cold seasons. Forcing culture experiments were conducted in semi-cold season (once, April to May, 2013) and cold season (twice, March, 2014; March, 2015). In each experiment, cow compost produced through solid-liquid separator (water content; 72.6%) was used as heat sources. Temperature of outside air, indoor air, compost container, forcing chambers (soil and air) and heat exchangers were recorded. Through all experiments, compost temperature was maintained up to 30°C, and it showed potential to be used as a heat source for chicory forcing culture. In semi-cold season, temperatures of forcing chambers (6.3 (cid:4) 0.9 (cid:4) 0.65 m) were maintained stably, and average air temperature of forcing chamber reached 17.2°C in average, and marketable etiolated heads (Chicon) were obtained after 22 d. In cold season, air temperature of forcing chamber (3.0 (cid:4) 0.9 (cid:4) 0.65 m) was maintained stably (10.6°C in 2014, 14.4°C in 2015, in average), and marketable heads were obtained after 15 to 19 d. The results indicated that witloof chicory forcing culture in semi-cold and cold seasons by using cow manure fermentation heat as heat sources is indeed possible.
菊苣的强制培养利用牛粪的发酵热
本研究探讨了在北海道半冷、冷季节利用牛粪发酵热生产菊苣的可行性。在半冷季(2013年4 - 5月1次)和冷季(2014年3月2次)进行强制培养实验;2015年3月)。在每个试验中,通过固液分离器生产的奶牛堆肥(含水量;72.6%)作为热源。记录了室外空气、室内空气、堆肥容器、强迫室(土壤和空气)和热交换器的温度。通过所有试验,堆肥温度保持在30℃以上,显示出作为菊苣强制培养热源的潜力。在半冷季,强迫室温度(6.3 (cid:4) 0.9 (cid:4) 0.65 m)保持稳定,强迫室平均气温平均达到17.2℃,22 d后获得可销售的黄化头(Chicon)。在冷季,强迫室气温(3.0 (cid:4) 0.9 (cid:4) 0.65 m)保持稳定(2014年10.6℃,2015年平均14.4℃);结果表明,以牛粪发酵热为热源,在半冷季和冷季不进行菊苣强制培养是可行的。
