Abstract
The invention provides a compound fertilizer suitable for growing corn in mid-low fertility areas. The compound fertilizer is characterized in that the mass ratio of nitrogen, phosphorus and potassium in the compound fertilizer is 20:7:18; the total mass of nitrogen, phosphorus and potassium is 45%; and the compound fertilizer is obtained by grinding the above components, mixing the powder uniformly, then granulating the mixture and then drying, cooling and screening the granules. The compound fertilizer has the beneficial effects that compound fertilizer efficiency maximization is achieved by optimizing preparation of the components of the compound fertilizer; and the compound fertilizer is especially suitable for the soil in the southern mountainous areas in Anhui Province and has greater application prospect.
Description
Technical field
The present invention relates to a kind of composite fertilizer, be specifically related to the composite fertilizer of low fertility area corn planting in a kind of being applicable to.
Background technology
Composite fertilizer has that nutrient content is high, minor component is few and the advantage such as physical behavior is good, for balance fertilizing, improves utilization rate of fertilizer, promotes the stable high yield of crop that very important effect is arranged, and is the important substance basis of improving crop yield.But it also has some shortcomings, and is always fixing such as its nutrients ratio, and different soils, required nutritive element kind, quantity and the ratio of Different Crop are various.Be directed to unique landforms and the soil characteristic of Wannan mountainous area, if only do not use Common compound fertilizer for edatope, then not only can affect the output of farm crop, also can affect the agricultural-food mouthfeel.
Summary of the invention
For above the deficiencies in the prior art, the invention provides the composite fertilizer of low fertility area corn planting in a kind of being applicable to.
The present invention is achieved by the following technical solutions:
The composite fertilizer of low fertility area corn planting in a kind of being applicable to, nitrogen, phosphorus, potassium mass content are 20-7-18 in the described composite fertilizer, the mass content total amount of nitrogen, phosphorus, potassium is 45%;
Above-mentioned each component raw material is pulverized granulation behind the mixing, again drying, cooling, screening, the composite fertilizer of low fertility area corn planting in namely obtaining being applicable to.
Beneficial effect of the present invention is: by the optimization to composite fertilizer's component preparation, reach the maximization of composite fertilizer's fertilizer efficiency, be specially adapted to the soil of Wannan mountainous area, has larger application prospect, not only can increase the output of farm crop, also can reach the purpose that improves the agricultural-food mouthfeel, make agricultural-food more adapt to social demand, more meet people's needs.
Embodiment
The invention provides in a kind of being applicable to the composite fertilizer of low fertility area corn planting, wherein nitrogen, phosphorus, potassium mass content are 20-7-18, and the mass content total amount of nitrogen, phosphorus, potassium is 45%.
Above-mentioned each component raw material is pulverized granulation behind the mixing, again drying, cooling, screening, the composite fertilizer of low fertility area corn planting in namely obtaining being applicable to.
The present invention is by the optimization to composite fertilizer's component preparation, reach the maximization of composite fertilizer's fertilizer efficiency, be specially adapted to the soil of Wannan mountainous area, has larger application prospect, not only can increase the output of farm crop, also can reach the purpose that improves the agricultural-food mouthfeel, make agricultural-food more adapt to social demand, more meet people's needs.
