优化设施环境 生产安全农产品

内蒙古敖汉旗从河北保定引进了较先进的节能日光温室和连栋温室,通过采取多层覆盖等措施,实现了在北纬40°左右寒冷地区冬季不加温情况下喜温果菜的安全生产。通过应用外保温空心砖墙、消雾棚膜、内外遮阳、微喷灌、防虫网、诱虫板、燃煤热风炉等配套技术,实行配方施肥,增施沼渣或生物菌肥。推广黄瓜、茄子嫁接和果实套袋栽培,可减少农药污染和有效改善品质。为解决以前设施农业生产中经常出现的诸如:温室采光保温设计不合理、竹木土墙架构的棚室简陋、病虫为害不断加重、连作障碍增加等问题提供了较好的解决方案,并提出了设施农业如何生产出质量安全的农产品的切实可行的途径和方法。

Optimized Facilities Agriculture Environment to Produce Safe Farm Product

Aohan Qi,a county of Inner Mongolia has brought in more advanced energy-saving greenhouse and multy 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.
