Problems solved by technology

However, the cost of the patented bacterial fertilizer is relatively high, and the accumulation effect of crop dry matter is not clear
[0007] In summary, although there are many reports on special fertilizers for corn, they not only lack regional pertinence, but also have a single improvement method. Humic acid is activated by birnessite-type manganese oxide, and then used as a special fertilizer for corn in calcareous soil areas in Shandong. Haven't seen any reports yet
Since the regional climate characteristics will affect the release of fertilizer nutrients, the nutrient release characteristics of the existing corn special fertilizers are difficult to match the nutrient absorption rules of corn in calcareous soil areas in Shandong and Luxi. It is of great significance to improve the soil and use it easily, and the special fertilizer for summer corn in line with the calcareous soil characteristics and climate characteristics of Luxi

Abstract

The invention discloses special humic acid synergistic fertilizer for summer corn in a calcareous soil area of Shandong province and a preparation method of the humic acid synergistic fertilizer. Thespecial humic acid synergistic fertilizer comprises the following components: in parts by weight, 30-40 parts of polymer-coated controlled release urea, 15-20 parts of physiological acid phosphate fertilizer, 15-30 parts of physiological acid potassium fertilizer and 15-18 parts of manganese oxide-activated humic acid synergistic urea, wherein the mass ratio of nitrogen to phosphorus to potassiumin chemical nutrients of the special fertilizer is as follows: N:P205:K2O = 11:4:6, the content of the manganese oxide-activated humic acid is 5.5-6.0%, and controlled-release nitrogen accounts for 36.4% of the total nitrogen. The special humic acid synergistic slow-controlled release blended fertilizer for summer corn in the calcareous soil area of the western Shandong has pertinence, and is suitable for planting of summer corn in the calcareous soil area of the western Shandong, and significant increase of the yield can be achieved after use.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for humic acid synergistic type summer corn in calcareous soil areas of Shandong and a preparation method thereof. Background technique [0002] Calcareous soil is a general term for soils containing calcareous substances such as calcium carbonate or calcium bicarbonate in the profile. It is characterized in that there is a lime reaction, that is, after adding hydrochloric acid dropwise, carbon dioxide bubbles are generated by the action of carbonate and acid. This type of soil is alkaline, the base is saturated, and the mineral nutrients such as calcium and magnesium are rich. [0003] The western part of Shandong Province is located in the western part of Shandong Province. It is an alluvial plain of the Yellow River. The terrain is flat and the climate resources are relatively rich, which can be compensated by the irrigation of the water of the Yellow...
