Abstract

The invention relates to a fertilizer special for spring corn. The fertilizer special for spring corn is prepared from, by weight, 1-3 parts of composite coating powder, 4-6 parts of a urease inhibitor, 5-8 parts of paraffin nitrification inhibitor urea, 4-6 parts of wintergreen oil, 7-9 parts of paraffin, 7-10 parts of an organic matter, 40-45 parts of diammonium phosphate, 40-45 parts of potassium chloride, 1-2 parts of zinc sulfate, 4-6 parts of humic acid, 1-2 parts of radix stemonae powder, and 0.5-1.5 parts of attapulgite. Through reasonable compounding of all the nutrient elements needed by spring corn growth, the prepared fertilizer can meet the demands of corn for various nutrients, nanocrystallization of attapulgite can endow the fertilizer provided by the invention with better slow release effect, under the circumstance of an equal slow-release effect, less nanocrystallized attapulgite is consumed, therefore the fertilizer can be more environmentally friendly, camphor tree powder has good bactericidal and insecticidal effect, and the effect can be reflected lastingly under a coating condition. During preparation of the fertilizer provided by the invention, as certain micropores can be generated on the wintergreen oil and composite coating powder coating layer, spraying of paraffin can effectively extend the slow release performance.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special fertilizer for spring corn. Background technique [0002] In my country, most of the corn is planted in hilly and mountainous areas, where the soil layer is thin and the fertility is low. Farmyard manure is mainly organic fertilizer, which is rich in nutrients, can improve the soil, fertilize the land, and have a long fertilizer effect. Chemical fertilizers are quick-acting fertilizers. Although they also contain the nutrients needed by corn, compared with farmyard manure, the nutrients are still single. At the same time, during the application of chemical fertilizers, other components remain, which is not conducive to the growth of corn and the improvement of soil fertility. [0003] Coated fertilizers are also called coated fertilizers and film fertilizers. Fertilizers made of quick-acting fertilizer granules wrapped with semi-permeable or impermeable film substances.
