Abstract: Aohan Qi, a county of Inner Mongolia has brought in more advanced energy-saving greenhouse and muhy span greenhouse from Baoding of Hebei Province, which implement the safe production of thermophilic fruits and vegetables without heating in winter season within a cold area about 40 degree of north latitude after adopting measures such as multilayer covering and more. Via serial advanced technology, including heat-insulation wall formed by hollow bricks, fog-free thin film, inside and outside sunshade, microspray irrigation, anti-worm net, enticing worm board and hot coal furnace, we have successfuly carried out formula fertilization and increasing application of biogas residue or biological fertilizer. Application of grafting thchniques of cucumber, eggplant, and fruit bagging cultivation is able to reduce pesticide pollution and improve the quality more efficiently. We provide better solutions to some common problems in facility agriculture, such as poor light absorption and heat preservation of greenhouse, rough structure of bamboo walls, more insect damage and increasing difficulty of continuous cropping. At same time, We provide more practical methods and stratagies for safe farm production in facility agriculture.
