Embodiment 1

[0044] The weight composition of the macronutrient special fertilizer of the test group is: N:P 2 o 5 :K 2 O=12:8:10. Nitrogen fertilizer is urea, N content is 46%; Phosphate fertilizer is superphosphate, P 2 o 5 The content is 12%; Potassium fertilizer is potassium chloride, K 2 The O content is 60%. The weight composition of the special fertilizer for micronutrient elements is: zinc sulfate: borax: manganese sulfate: ferrous sulfate=1:0.5:1:0.5. The special fertilizer for macronutrient elements and the special fertilizer for micronutrient elements are respectively stirred evenly, and the compound fertilizer is granulated. The total amount of chemical fertilizers is 81kg / mu, of which, the amount of special fertilizer for macronutrients is 80kg / mu, and the amount of fertilizer for micronutrients is 1kg / mu. The fertilizer is applied in one time. Before the corn site is sown, the special fertilizer for the micronutrient elements is sprinkled at one time; The horizontal d...

Abstract

Aiming at solving the problems of large usage amount of fertilizer, multiple fertilization times, low utilization rate and the like of summer maize in Huaibei plain of China, the invention provides special fertilizer for the summer maize and a one-time fertilization method of the special fertilizer. The special fertilizer for macro nutrient elements is characterized in that a weight ratio of N toP2O5 to K2O is equal to (10 to 18) : (4 to 10) : (6 to 12); the special fertilizer for trace nutrient elements is characterized that a weight ratio of zinc sulfate to borax to manganese sulfate to ferrous sulfate is equal to (1 to 2) : (0.5 to 1.5) : (1 to 2) : (0.5 to 1.5). According to the growth characteristics, fertilizer requirement characteristics and migration and diffusion of fertilizer nutrients of the summer maize in Huaibei plain, disclosed by the invention, trace element fertilizer is applied at one time while the macronutrient fertilizer is applied in holes at one time; compared with traditional split application, the one-time fertilization method has the advantages that fertilizer is saved, the utilization rate is improved, and the yield is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilization, and in particular relates to a special fertilizer for summer corn and a one-time application method thereof. Background technique [0002] Fertilization is an important guarantee for crop yield and quality, but excessive fertilization and low fertilizer utilization have become bottlenecks and prominent problems restricting the development of modern agriculture in my country. Research by Zhang Fusuo et al. shows that the fertilizer use efficiency of nitrogen, phosphorus and potassium fertilizers for corn in my country is 26.1%, 11.0% and 31.9%, respectively, while the nitrogen use efficiency of summer maize in the North China Plain is even less than 15%. Therefore, how to further scientifically apply fertilizers to achieve high and stable yields of corn while improving fertilizer use efficiency and reducing losses has become a strategic problem to be solved urgently. On the bas...
