Compound fertilizer applicable to cucumber cultivation in milled/low-fertility area

Abstract

The invention provides a compound fertilizer applicable to cucumber cultivation in milled / low-fertility areas. The mass contents of nitrogen, phosphorus and potassium in the compound fertilizer are 20, 8 and 15; the total mass content of the nitrogen, the phosphorus and the potassium is 43%; the compound fertilizer contains a microelement Mn of which the content is 0.5%; the compound fertilizer applicable to cucumber cultivation in milled / low-fertility areas is obtained by crushing the raw materials, uniformly mixing, palletizing, further drying, cooling and screening. By optimizing the compound fertilizer component preparation, the maximization on the fertilizer efficiency of the compound fertilizer is achieved, so that the compound fertilizer is particularly applicable to soil in southern mountainous areas in Anhui Province, and has a large application prospect.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a compound fertilizer suitable for growing cucumbers 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, it ...
