A kind of landscaping high-nutrition and environment-friendly compound fertilizer formula

Abstract

The invention belongs to the technical field of fertilizer production, and in particular relates to a garden greening high-nutrition environmentally-friendly compound fertilizer formula and a preparation method and application thereof, and the garden greening high-nutrition environmentally-friendly compound fertilizer comprises 45-75 parts of humic acid fertilizer, 25-35 parts of urea, 5-15 parts of potassium nitrate, 7-14 parts of monoammonium phosphate, 5-12 parts of potassium dihydrogen phosphate, 10-20 parts of ammonium bicarbonate, 8-18 parts of magnesium sulfate, 5-10 parts of sodium citrate, 3-13 parts of molybdenum sulfate, 5-19 parts of calcium silicate, 8-19 parts of iron ammonium phosphate and 1-10 parts of EDTA chelated zinc. The formula has the advantages of improving soil aggregate structures, loosening soil, improving soil water and fertilizer conservation capacity, regulating pH value, reducing the content of heavy metals in the soil, and reducing the harm of salt ions to garden plants.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, in particular to a long-acting fertilizer, in particular to a formula of high-nutrition and environment-friendly compound fertilizer for landscaping and its preparation method and application. Background technique [0002] The 21st century is the development of the chemical industry. The amount of chemical fertilizers has increased sharply. Its long-term use has had a great impact on the soil. The part absorbed and utilized by crops only accounts for 30%-40% of the applied amount, and the rest exists in the soil. In severe cases, it pollutes the soil, affects the ecology of farmland, and even directly leads to soil salinization. In addition, for a long time, growers have applied N, P, and K macronutrient fertilizers, ignoring the supplement of medium and trace elements, resulting in an imbalance of nutrients in the soil, making it impossible for plants to effectively absorb and util...

AI Technical Summary

Problems solved by technology

[0004] The water-soluble fertilizer product of prior art mixing mainly has following problems: (1) appearance is not good

(2) The humidity of the product is high, causing agglomeration, which affects the use and sales

However, N, P, K and other large elements are still the main ones, which cannot well meet the needs of seedlings for medium and trace elements, and need to be supplemented separately, which increases the cost of fertilization

[0010] CN101284747A utilizes the complementary advantages of fast-acting fertilizer and organic fertilizer to prolong its fertilizer effect, but its fertilizer effect is still short, and generally needs to be applied 1-2 times a year
