Problems solved by technology

[0002] The cultivation area of ​​corn in solar greenhouses in the Hexi Corridor of Gansu Province has grown to more than 50,000 mu. At present, the main problems that are becoming more and more prominent are: the continuous cropping period of greenhouse corn is long, the number of harmful organisms is increasing, and the proportion of nutrients is unbalanced; excessive use of chemical fertilizers, and the nitrate of corn exceeds the standard ; The amount of organic fertilizer input is small, the content of organic matter in the soil decreases, and the water retention capacity of the soil decreases; the traditional compound fertilizer applied by farmers does not contain organic matter, and does not have the effect of disease prevention, resulting in serious corn diseases and a decline in yield and quality

Abstract

The invention relates to a corn multifunctional medical fertilizer. The medical fertilizer is characterized by comprising, by mass, 34.3-34.8 parts of a rapeseed cake fertilizer, 25.5-26 parts of potassium sulfate, 25-25.6 parts of urea, 10-10.5 parts of monoammonium phosphate, 0.49-0.8 part of previcur, 0.55-0.6 part of thiophanate methyl, 0.45-0.5 part of citric acid, 0.45-0.5 part of EDTA, 0.35-0.4 part of benomyl, 0.15-0.2 part of zhongshengmycin, and 0.05-0.1 part of brassinolide. The medical fertilizer integrates nutritive actions of the rapeseed cake fertilizer, potassium sulfate, ureaand monoammonium phosphate, the complexation action of EDTA, disease-preventing actions of previcur, thiophanate methyl, benomyl and zhongshengmycin, and the growth-promoting action of brassinolide together, so that problems such as long years of corn continuous cropping, soil nutrient ratio imbalance, organic matter reduction, low fertilizer utilization rate, serious soil-borne diseases and the like are solved. The medical fertilizer is applied to fields such as corn fertilizer production, soil nutrient supplement in corn planting, corn disease prevention and treatment, and the like.
