Problems solved by technology

[0003] Existing maize production is mainly increased through the application of fertilizers in addition to genetic technology. Traditionally applied fertilizers are not targeted, and the yield increase effect is not obvious. Existing special fertilizers for maize mainly increase production by providing sufficient elements for slow release, which is less damaging to the soil. Serious, high cost

Abstract

The invention discloses special fertilizer for corn and a preparation method thereof. The special fertilizer for corn is prepared from the following raw materials in parts by weight: 20 to 30 parts ofcomposite fertilizer, 15 to 25 parts of humic acid, 10 to 20 parts of distillers' grains, 12 to 16 parts of polylactic acid, 6 to 10 parts of medical stone, 3 to 7 parts of calomel, and 1 to 5 partsof armillariella tabescens. The special fertilizer for corn has the advantages that by using the composite fertilizer, the humic acid, the distillers' grains, the polylactic acid, the medical stone, the calomel and the armillariella tabescens as the raw materials, the distillers' grains can be fully utilized, the usage amount of chemical fertilizer is reduced, the destruction to soil is reduced, the output increasing effect of the prepared special fertilizer for the corn is obvious, the usage amount of the special fertilizer for corn is small, and the use cost is low; the preparation technology is simple, and the industrialized production can be easily realized.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special fertilizer for corn and a preparation method thereof. Background technique [0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture includes the production of food crops, cash crops, fodder crops, green manure and other crops, and is the basic product that supports the construction and development of the national economy. Corn is an important food crop and feed crop, and it is also the crop with the highest total yield in the world. It is rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrition and high-biological function foods. Corn production is crucial to economic development. [0003] Existing maize production is mainly increased through the application of fertilizers in addition to genetic technology. Traditionally...
