Abstract

The invention belongs to the field of crop fertilizers and particularly relates to a special ecological fertilizer for acid soil and a preparation method thereof. The special ecological fertilizer is characterized by consisting of puccinellia tenuiflora, moso bamboo leaves, traditional Chinese medicine residue, oyster powder, ammonium bicarbonate, ground phosphate rock, plant ash, magnesium amino acid, sodium molybdate, pectin, sucrose and a soil conditioner. With a dominated organic fertilizer, the special ecological fertilizer provided by the invention is rich in humic acid, amino acid and protein; through compound addition of appropriate alkaline inorganic fertilizer, the special ecological fertilizer is comprehensive in nutrition and can perfectly meet the nutrient needs in crop growth; and moreover, the soil conditioner in the fertilizer can adsorb plenty of aluminum ions and iron ions in acid soil so as to reduce the fixation of a phosphate fertilizer, enhance the cation adsorption capacity of the soil, reduce the eluviation of the soil and improve the utilization rate of the fertilizer.

Description

technical field [0001] The invention belongs to the field of slow-release fertilizers, in particular to a special ecological fertilizer for acidic soil and a preparation method thereof. Background technique [0002] In my country's tropical and subtropical regions such as Zhejiang, Fujian, Hainan, Guangxi, Yunnan, Guizhou, etc., acidic soils are widely distributed. The main types are red soil, red soil, brick red soil, etc. The pH of most soils is between 4.5 and 6.0. With the large-scale application of chemical fertilizers and the unreasonable combination of organic and inorganic fertilizers in recent years, soil acidification has gradually increased, and has seriously affected land productivity in a local area. Soil acidification directly affects the activity of microorganisms in the soil and reduces the diversity of soil microorganisms. The free iron and aluminum in acidic soil are highly active, and form insoluble iron phosphorus and aluminum phosphorus with phosphorus, ...
