一、气肥:棚菜施用二氧化碳气肥量合适的浓度为1000～1200PPm。施用方法主要有5种:一是增施有机肥,每亩施用半腐熟有机肥5～10吨,就会不断地分解出二氧化碳。未腐熟的有机肥容易生地下害虫,已腐熟的有机肥释放二氧化碳量太少。二是深施碳酸氢铵,要求每平方米施用10克,深施5～8厘米,每半月一次,可释放出二氧化碳气肥。三是燃烧沼气和点沼气灯。四是燃烧煤油和石油液化气。1公斤煤油完成燃烧可生成2450毫克二氧化碳,1公斤石油液化气安全燃烧可生成2750毫克二氧化碳。五是推广固体二氧化碳气肥。这种固体二氧化碳气肥,是山东省农科院原子能
First, gas fertilizer: Greenhouse carbon dioxide gas fertilizer application of the appropriate concentration of 1000 ~ 1200PPm. There are five main application methods: First, increase the application of organic fertilizer, semi-matured organic fertilizer per acre 5 to 10 tons, will continue to break down the carbon dioxide. Undegraded organic fertilizer prone to underground pests, decomposed organic fertilizer release too little carbon dioxide. Second, the deep application of ammonium bicarbonate, application of 10 grams per square meter, 5 to 8 cm deep application, once every two months, can release carbon dioxide gas fertilizer. Third, the burning of biogas and biogas burner. Fourth, burn kerosene and liquefied petroleum gas. 1 kg of kerosene to complete the combustion can generate 2,450 mg of carbon dioxide, 1 kg of liquefied petroleum gas safely combustion can generate 2750 mg of carbon dioxide. Fifth, to promote solid carbon dioxide gas fertilizer. This solid carbon dioxide gas fertilizer, Shandong Academy of Agricultural Sciences atomic energy
