Seaweed organic fertilizer

Abstract

The invention discloses a seaweed organic fertilizer, which is prepared from the following raw materials (by weight): 54-56 parts of seaweed slag, 22-24 parts of activated sludge, 10-11 parts of peanut meal, 4-5 parts of sodium carboxymethyl starch, 8-10 parts of peat powder, 3-4 parts of sodium dihydrogen phosphate, 7-9 parts of potassium chloride, 35-37 parts of compost coarse particle, 40-44 parts of sunflower straw, 2.5-2.8 parts of dodecyl dimethyl betaine, 1.8-2.2 parts of Tween 80, 14-16 parts of bentonite and a proper amount of water. according to the organic fertilizer, seaweed slag obtained after processing of seaweed is used as the main raw material, and the seaweed slag and other raw materials such as activated sludge, etc. are fermented. Thus, secondary utilization of waste resources is realized. In cooperation with raw materials such as peat powder, potassium chloride, etc., nutrient content of the fertilizer is enriched. Natural active components such as lots of phytohormone in the seaweed fermented product also can promote growth of plant root system and leaf stems and enhance stress resistance of plants.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a seaweed organic fertilizer. Background technique [0002] With the increasing level of agricultural modernization, organic fertilizers are gradually replacing ordinary chemical fertilizers and becoming an important fertilizer in agricultural production. Organic fertilizers have many advantages such as complete nutrition, improved soil, and increased fertilizer utilization. However, the organic fertilizers currently available on the market have many defects. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, they cannot meet the needs of soil pollution restoration. Simple soil structure Improvement cannot improve the quality of crops in polluted soil; third, the supply of nutrients is slow, and although it is more effective than ordinary ch...

However, the organic fertilizers currently available on the market have many defects. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, they cannot meet the needs of soil pollution restoration. Simple soil structure Improvement cannot improve the quality of crops in polluted soil; third, the supply of nutrients is slow, and although it is more effective than ordinary chemical fertilizers, it is difficult to meet the nutrient needs of plants when they grow vigorously; fourth, fertilizers are bulky and inconvenient to transport and store; fifth, for special The soil environment such as acid-base, drought-humidity, soil lacking some elements and the nutrient requirements of specific crops are not effectively targeted
