Abstract

The invention discloses an environment-friendly slow-release fertilizer for aquaculture aquatic plants. The environment-friendly slow-release fertilizer is prepared from, by weight, 10-20 parts of potassium chloride, 5-15 parts of urea, 5-20 parts of potash magnesium sulphate fertilizer, 0.5-2 parts of decomposed coal, 1-2 parts of turf, 1-3 parts of zeolite powder, 0.5-1.2 parts of calcium humate, 0.5-1 part of magnesium humate, 0.1-0.6 part of boron humate, 0.2-0.8 part of sodium humate, 0.15-0.4 part of compound sodium nitrophenolate, 1-2 parts of olive oil, 1.2-3 parts of sodium carboxymethylcellulose and 2-5 parts of a controlled-release coating agent. The coat of the fertilizer is not likely to break, the fertilizer is good in granule uniformity and environmentally friendly, and the fertilization property accords with the fertilizer requirement law of aquatic plants.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an environmentally friendly slow-release fertilizer for aquatic plants. Background technique [0002] Aquatic plants can also absorb ammonia nitrogen and inorganic nutrient salts in water, compete for nutrient sources for algae growth, reduce and desalinate water fertility, reduce the harm of ammonia nitrogen and nitrite to aquaculture organisms, increase water transparency, stabilize pH value, and make The water body remains alkaline, which is conducive to the growth and development of freshwater shrimp and crabs. Aquatic plants themselves contain many medicinal ingredients, such as alkaloids, organic acids, aminopurines, pyrimidines and other organic substances, which have the functions of sterilization, anti-inflammation, detoxification, swelling, hemostasis, and strength. pharmacological effects. The health of aquatic plants in ponds needs to be carefully maintained, bu...
