Problems solved by technology

But it also has some disadvantages, such as its nutrient ratio is always fixed, and the types, quantities and ratios of nutrient elements required by different soils and different crops are varied.
In view of the unique topography and soil characteristics of the mountainous area in southern Anhui, if ordinary compound fertilizers are only applied without targeting the soil environment, it will not only affect the yield of crops, but also affect the taste of agricultural products

The present invention achieves the maximization of compound fertilizer efficiency by the optimization of compound fertilizer component preparation, is especially suitable for the soil of the southern mountains of Anhui Province, and has great application prospects.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a compound fertilizer suitable for planting broad beans in middle and low fertility areas. Background technique [0002] Compound fertilizer has the advantages of medium and low nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving the utilization rate of medium and low fertilizers, and promoting the stable yield of medium and low crops. It is an important substance to increase the yield of medium and low crops. Base. But it also has some disadvantages, such as its nutrient ratio is always fixed, but the types, quantities and ratios of nutrient elements required by different soils and different crops are varied. In view of the unique topography and soil characteristics of the mountainous area in southern Anhui, if ordinary compound fertilizers are only applied without targeting the soil environment, ...
