所谓生态温室就是日光温室内侧建点沼气池,沼气池上搞畜禽养殖,温室内其他土地搞种槙,备禽粪使和作物秸秆入沼气池,温室在冬季为沼气的产生提供温度保证,沼气为室内的植物提供二氧化碳气肥和加温的燃料,沼渣、沼液为植物生长提供优质有机肥和高效生物农药。生态温室具有良好的经济效益和生态效益。生态温室中沼气池的建设和管理及“三沼”(沼气、沼液、沼渣)综合利用技术主要有以下几点:一、生态温室中沼气池的建设和管理1.沼气池位置的确定住生态温室中,日光温室要用第二代节能犁日光湍室。技术性能上要求:冬至前后,每天采光时间保持6小时以上;日出前室内气温在10℃以上。畜禽舍必须设在生态温室总体平面的西侧、东测或北删。沼气池建在畜禽舍地下,应做到便于保温和日常管理。
The so-called ecological greenhouse is built inside the solar greenhouse biogas digesters, biogas digesters engage in livestock and poultry breeding, other land in the greenhouse to engage in breeding 槙, prepared poultry manure and crop stalks into the digester, greenhouses in the winter to provide biogas production temperature to ensure biogas Provide indoor plants with carbon dioxide gas and heating fuel, biogas residue, biogas slurry for the plant to provide high-quality organic fertilizer and efficient biological pesticides. Ecological greenhouse has good economic and ecological benefits. The construction and management of biogas digesters in eco-greenhouses and the comprehensive utilization technologies of “three marsh” (biogas, biogas slurry and biogas residue) mainly include the following points: I. Construction and Management of Biogas Digesters in Ecological Greenhouses 1. Determination of Digester Location Live ecological greenhouse, solar greenhouse to use the second generation of energy-saving plow sun turbulence room. Technical performance requirements: before and after the winter solstice, daily lighting time to maintain more than 6 hours; before sunrise indoor temperature above 10 ℃. Livestock poultry houses must be located on the west side of the general plan of the ecological greenhouse, east or north delete. Biogas digesters built in livestock and poultry under the ground, should be easy to heat and daily management.
