Abstract

The invention discloses a special slow-release fertilizer for maize and a preparation method of the special slow-release fertilizer, belongs to the technical field of fertilizers, and aims at solving the technical problem of providing the special slow-release fertilizer for maize, which is sufficient and lasting in fertilizer efficiency. According to a technical scheme for solving the technical problem, the special slow-release fertilizer for the maize is formed by an inorganic core material and an organic coating material, wherein the inorganic core material is prepared from the following components in parts by weight: 20-30 parts of monoammonium phosphate, 10-15 parts of urea and 10-15 parts of monopotassium phosphate; and the organic coating material is prepared from the following components in parts by weight: 30-40 parts of animal dung, 10-13 parts of maize straws, 1-2 parts of radix stemonae, 1-2 parts of radix asparagi, 2-3 parts of radix sophorae flavescentis, 1-2 parts of towel gourd flower, 3-5 parts of shrimp shell meal, 3-5 parts of fish bone meal, 2-4 parts of waste bacteria sticks, 4-7 parts of coal gangue, 3-5 parts of ultrafine fly ashes and 0.05-0.2 part of saccharomycetes. The special slow-release fertilizer for the maize is lasting in fertilizer efficiency, and is capable of obviously improving the quality of crops and increasing the yield. The special slow-release fertilizer can be widely applied to the field of maize production.

Description

technical field [0001] The invention discloses a special slow-release fertilizer for corn and a preparation method thereof, belonging to the technical field of fertilizer preparation. Background technique [0002] Corn is an important food crop and economic crop. Statistics show that among the cereal crops in the world, the planting area and total output of corn ranks third after wheat and rice, and its average yield ranks first. To increase the yield per unit area of ​​corn is inseparable from the use of fertilizers. [0003] At present, in the process of corn growth, inorganic fertilizers are widely used. Although inorganic fertilizers have fast fertilizer efficiency and are easy to use, they also have the disadvantages of single nutrient and short-lasting fertilizer effect, which leads to the need for multiple fertilization in the later stage, resulting in an increase in labor costs. In addition, the excessive use of inorganic fertilizers can easily lead to more serious...
