日光温室应用秸秆反应堆对地温的影响

日光温室应用秸秆反应堆技术,具有改善作物生长环境、提高地温、培肥土壤、降低连作障碍、增强植物抗病能力的作用,能从根本上解决因大量施用化肥和农药导致的农产品质量安全问题,是推动秸秆和畜禽粪便综合利用,提高农产品产量和质量的一项有效措施.试验表明,在每栋温室用秸秆4000kg左右,温室内CO2浓度明显增加,在最冷的12月和1月可使耕层平均地温提高0.5～1.0℃,土壤温差缩小,减少有机肥、化肥和农药用量50％以上.

Effect of Application of Straw Reactor on Soil Temperature in Greenhouse

Applying the straw reactor in greenhouse can improve the growth environment of crops and the soil temperature, fertilize soil, reduce obstacles of continuous cropping, enhance disease resistance of plants. It can thoroughly avoid quality and safety problem of agricultural products resulting from application of quantities of chemical fertilizer and pesticide. It is an effective measure that can promote the integrated utilization of straw and manure livestock and poutry, increase yield and improve quality. The experiment results showed that the concentration of CO2 increased obviously when about 4000kg straw applied in each greenhouse, even in the coldest December and January the soil temperature rised 0.5-1.0℃, soil temperature difference smaller, and reduce more than half of the use of organic fertilizers, chemical fertilizers and pesticide.
