Warming technology and equipment of intensive seedling cultivation in Tianjintaking application of Tianjin Xingyou Agricultural Technology Co.，Ltd. as an example

There are problems with insufficient technical level and equipment in intensive seedling cultivation process in Tianjin．Among them, low temperature in winter is the biggest resistance factor for cultivating strong seedlings, and too low temperature can lead to stiff or dead seedlings．Four warming techniques and equipment that could be applied to intensive seedling cultivation were introduced．Conduct experiments were done in facility agriculture park of Tianjin Xingyou Agricultural Technology Co., Ltd．Energy consumption, temperature, heating effect, and usage cost were analyzed and compared．Results indicated that intelligent temperature controlled electric heating equipment had the best heating effect and the lowest cost was using geothermal water air conditioning equipment．Users need to choose suitable heating equipment according to their actual situation and local conditions．
