Abstract

The invention relates to a fertilizer special for corn, and concretely relates to a half-organic fermentation fertilizer fertilized to corn and a preparation method thereof. The to-be solved technical problem is to provide the half-organic half-inorganic fertilizer special for corn plantation in wheat and corn continuous cropping, wheat straws and hard stubbles are effectively utilized, the microbe content in siol is increased, and continuous cropping obstacle is reduced. The employed technical scheme comprises that the fertilizer special for corn comprises the following raw materials in parts by mass: 35-43 parts of urea, 30-35 parts of diammonium hydrogenphosphate, 15-18 parts of potassium chloride, 1-2 parts of zinc sulfate, 5-8 parts of microelement fertilizer, 30-40 parts of wheat straw, 5-8 parts of fulvic acid, 25-30 parts of humic acid. A preparation method of the fertilizer is shown in the specification.

Description

technical field [0001] The invention relates to a special fertilizer for corn, in particular to a semi-organic fermented fertilizer used as a corn seed fertilizer, and to a preparation method thereof. Background technique [0002] There are two kinds of by-products after wheat harvesting, one is the harvested wheat straw, and the other is the hard stubble left in the ground. Usually the hard stubble in the field will be plowed into the soil, but often there are still undecomposed wheat hard stubble after continuous cropping of corn in autumn. This poses a great hidden danger to the fertility of the soil. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and the technical problem to be solved is to provide a semi-organic and semi-inorganic special fertilizer for corn planting in continuous cropping of wheat and corn, which can not only effectively utilize wheat straw and hard stubble, but also increase soil microbial cont...
