Embodiment 1

[0012] Embodiment 1: The production of this special compound fertilizer adopts a new type of high-tower granulation production process. will contain P 2 o 5 110 kg of monoammonium phosphate containing 44% and 11% of N, 344.2 kg of urea containing 46.3% of N, 370 kg of potassium sulfate containing 50% of K, containing K 2 35.8 kg of potassium chloride with 60% O content, 10 kg of zinc sulfate heptahydrate with 21% Zn content, 130 kg of filler, melted into liquid by urea and potassium chloride, and mixed with potassium sulfate, filler, monoammonium phosphate, heptahydrate After the zinc sulfate water is mixed evenly, it is sprayed from a high altitude using a granulator, and then the qualified product is finally produced after cooling, sieving, and coating. The ratio of nitrogen:phosphorus:potassium:zinc in the prepared compound fertilizer is 16:5:22:0.2, which is the optimum value.

Embodiment 2

[0013] Embodiment two: each raw material is mixed according to the following weight ratio, and compound fertilizer is prepared by the method for embodiment one: 345 kilograms of urea containing 46.3% of N content, containing P 2 o 5 110 kg of monoammonium phosphate with 44% N content and 10% N content, 350 kg potassium sulfate with 50% K content, K 2 35 kilograms of potassium chloride with 60% O amount, 10 kilograms of zinc sulfate heptahydrate with 21% Zn content, and 150 kilograms of fillers. The ratio of nitrogen:phosphorus:potassium:zinc in the prepared compound fertilizer is 17:5:21:0.2.

Embodiment 3

[0014] Embodiment three: the raw materials are mixed according to the following weight ratio, and the compound fertilizer is prepared by the method of embodiment one: 360 kilograms of urea containing 46.3% of N content, containing P 2 o 5 140 kg of monoammonium phosphate with 44% N content and 10% N content, 320 kg of potassium sulfate with 50% K content, K 2 30 kilograms of potassium chloride with 60% O amount, 10 kilograms of zinc sulfate heptahydrate with 21% Zn content, and 140 kilograms of fillers. The ratio of nitrogen:phosphorus:potassium:zinc in the prepared compound fertilizer is 18:6:19:0.2.

Abstract

The invention relates to a special compound fertilizer for vegetables and fruits. In the compound fertilizer, the ratio of nitrogen to phosphorus to potassium to zinc is 15-20:5-8:18-25:0.18-0.25. The compound fertilizer can effectively promote the synthesis of auxin, has uniform nutrients, is difficult to agglomerate, has good water-solubility and high fertilizer effect, is favorable for fertilization, and can also be used for chlorine-sensitive plants.

Description

technical field [0001] The invention relates to agricultural fertilizers, in particular to the technical field of economic crops, including special compound fertilizers for vegetables and fruits. Background technique [0002] Vegetables and fruits are important foods in people's daily life. Although there are many types and varieties of them, they have many similar characteristics in chemical composition and nutritional value. At present, there are many kinds of compound fertilizers on the market, but none of them can ideally inject the required trace elements for different plants according to the needs of plant growth. The pertinence is poor, and it is difficult to effectively meet the needs of plant growth. Contents of the invention [0003] The purpose of the present invention is exactly to provide a kind of special-purpose compound fertilizer for the deficiency that there is no particularly effective special fertilizer for economic crops of vegetables and fruits on the...
