Abstract

The invention discloses long-acting slow release organic fertilizer which is prepared by raw materials in parts by weight as follows: 4-5 parts of activated carbon, 10-15 parts of edible starch pulp, 5-6 parts of zeolite powder, 7-8 parts of medical stone powder, 6-8 parts of gelidium amansii, 4-5 parts of potassium sulfate, 35-45 parts of animal waste, 12-18 parts of spirulina powder, 1-2 parts of talcum powder, 3-4 parts of ground phosphate rock, 5-6 parts of ammonium sulfate, 2-3 parts of urea, 3-4 parts of sodium sulfate, 5-6 parts of biochemical fulvic acid, 20-30 parts of a soil conditioner and appropriate water. The long-acting slow release organic fertilizer adopts a double-envelope structure comprising a molten urea layer and the talcum powder, by means of slow release of the urea and high adsorbability of the talcum powder, release of fertilizer nutrients can be controlled effectively, waste caused by the fact that a large quantity of fertilizer components cannot be effectively absorbed by plants is prevented, meanwhile, the added raw materials such as the gelidium amansii, the spirulina powder and the like contain large quantities of trace elements such as iron, calcium, magnesium and the like required by the plants, and healthy growth of the plants is facilitated.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a long-acting slow-release 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 imperative t...
