Abstract

The present invention discloses a water and fertilizer retention organic fertilizer made of the following raw materials by weight: 20-30 parts of sorghum straw charcoal powder, 6-8 parts of river silt, 2-3 parts of potassium mineral powder, 1-2 parts of calcium hydrogen phosphate, 4-5 parts of EDTA chelated zinc, 4-6 parts of died sweet potato, 5-6 parts of fulvic acid, 4-5 parts of durian shell, 3-4 parts of sunflower oil slag, 4-5 parts of potassium sulfate, 6-8 parts of ammonium nitrate, 35-45 parts of rape straw, 6-8 parts of gracilaria lemaneiformis, 8-10 parts of safflower seed oil residue, 20-30 parts of a soil conditioner, and the proper amount of water; the raw materials adopted by the fertilizer are wide in sources, are mainly non-pollution production waste, and effectively reduce the production cost, by a compounded coated granular structure, the fertilizer release time can be prolonged, soil water and fertilizer retention capacity can be improved, and the soil absorption, buffer and resistance properties can be improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a water- and fertilizer-retaining organic fertilizer and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and agriculture is the foundation of the national economy, of which planting accounts for more than half, and the quality of fertilizers directly affects the output of planting, and is an important factor for increasing crop production. However, in order to pursue crop yields, farmers blindly apply chemical fertilizers, resulting in a downward trend in soil organic matter content, weakened soil buffer capacity, decline in disaster resistance, low fertilizer use efficiency, and reduced soil fertility. With the emergence of environmental problems caused by excessive use of chemical fertilizers, the promotion of pollution-free agriculture, and the continuous expansion of the research field of new fertilizers, it is imper...
