Urea compound organic fertilizer for corns

Abstract

The invention discloses urea compound organic fertilizer for corns. The urea compound organic fertilizer is prepared from distillers' grains, plant ash, humic acid, urea, bentonite, potassium dihydrogen phosphate, calcium phosphate, charcoal powder, a waste edible mushroom culture medium, ammonium sulfate, potassium sulfate, a water-retaining agent, ammonium molybdate and sodium benzoate. The compound organic fertilizer for the corns, disclosed by the invention, has various different nutrient components and can meet requirements of the corns on fertilizer at different periods in a growth process; the fertility loss can be effectively reduced and the utilization rate of the fertilizer is improved. Therefore, the number of times of applying the fertilizer is reduced, the application amount is reduced and wastes are avoided; meanwhile, the possibility of causing pollution to a peripheral soil environment is avoided and underground water is not polluted.

Description

technical field [0001] The invention relates to a urea compound organic fertilizer for corn, which belongs to the technical field of chemical fertilizers. Background technique [0002] Maize is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop. It is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. Corn has always been known as a longevity food, rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrition, high-biological function foods. Corn plays an extremely important role in my country's food security. It is an important feed crop and an important raw material for food, chemical, fuel, and pharmaceutical industries. This shows the importance of corn. [0003] In corn planting, chemical fertilizers have a huge impact on it, which is the guarantee of corn yield. How...

Problems solved by technology

[0003] In corn planting, chemical fertilizers have a huge impact on it, which is the guarantee of corn production. However, traditional chemical fertilizers mostly use a single type of chemical fertilizer, which has a low use efficiency. Traditional compound fertilizers are not only weak to corn, but also cause damage to the soil after long-term use. It will cause soil compaction, which will seriously cause soil salinization, and will also affect water sources, which is not conducive to sustainable development
