Abstract

The invention provides a sweet corn functional fertilizer which comprises the following raw materials in percentage by weight: 30-45% of urea, 10-25% of monoammonium phosphate, 20-35% of potassium chloride, 5-20% of ammonium sulfate, 0.1-2% of borax, 0.05-0.5% of chelated zinc, 0.5-1.5% of a nano synergist, 0.1-1% of micro-molecule organic carbon and 0-30% of auxiliary materials. According to the sweet corn nutrient requirements and south soil characteristics, the biological source trace element chelated zinc, the nano synergist and the micro-molecule organic carbon are fused on the basis of nitrogen, phosphorus and potassium fertilizers, so that the fertilizer nutrients can be correspondingly released according to the sweet corn growth time, the fertilizer nutrient utilization rate is improved, and the nutrient requirements of sweet corn fruits are met. Moreover, the barren tip problem of the sweet corn due to zinc and boron deficiency at the flowering and milking stage and hollow kernels caused by potassium deficiency in the late growth stage can be solved, and the aims of increasing the yield and improving the quality are achieved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a nutritional functional fertilizer suitable for southern climate and soil and used in the growth process of sweet corn. Background technique [0002] Sweet corn has the characteristics of fragrance, sweetness, freshness, and crispness. It is rich in various nutrients such as carbohydrates, fats, and proteins necessary for the human body. It is a convenient and pure natural nutritional health product. Its planting area is located in the southern hilly area. , its growth characteristics have a large demand for nutrients, and it is easy to appear baldness and insufficiency of grains in the flower and grain stage, which are mostly caused by improper measures such as fertilizer and water and lack of nutrients. Potassium deficiency in the later stage causes the grains to be unfulfilled, so reasonable formula fertilization is the prerequisite for achieving high yield an...
