New type of biological fertilizer double micro-dioxide
A bio-fertilizer that provides carbon dioxide for photosynthesis when green plants such as vegetables, fruits and flowers are planted in agricultural protected areas. Double-micro-carbon dioxide gas fertilizers have recently begun to be applied in Zhejiang Province. The double-micro carbon dioxide gas fertilizer is a kind of white solid granular gas fertilizer produced by industrial microbial liquid fermentation, and it is subjected to a microbial solid fermentation process in the protected soil, at a certain temperature and humidity (relative humidity ≥80% Under light conditions, both carbon dioxide and organic fertilizer can be released. One crop per acre of protected land requires about 22 kg of double micro carbon dioxide gas fertilizer. With an increase of 7 kilograms per time, carbon dioxide gas can be produced within 30 to 40 days, and the maximum concentration is about 100 ppm. The results of tests conducted in 23 provinces, regions, and cities across the country show that the double-micro carbon dioxide gas fertilizer is safe, reliable, non-toxic and harmless, has a small amount of application, and has a large gas production rate. It generally has an increase rate of more than 20%, which is significantly better than other carbon dioxide fertilization technologies. . According to the Ningxia Xiji County experiment, the application of this fertilizer to cucumber and pepper increased by 46.1% and 31.2%, respectively, compared to the control.
