preparation example Construction

[0024] The preparation method of seaweed nitrophosphate fertilizer is to add 85-99 parts of nitrophosphate fertilizer solution to the neutralization reaction tank 3, then add 1-15 parts of alginic acid, stir and react evenly at 140°C, and then enter the evaporator feeding tank 5. Evaporate, granulate and cool after passing the test.

[0025] Such as figure 1 As shown, the seaweed nitrophosphate fertilizer, the alginic acid storage tank 1 is connected with the neutralization reaction tank 3 through the meter 2, the nitrophosphate fertilizer container 4 is connected with the neutralization reaction tank 3 through the meter 2, and the neutralization reaction tank 3 is connected with the evaporator feeding Groove 5 connection. The alginic acid storage tank 1 is filled with alginic acid, and the nitrophosphate fertilizer container 4 is filled with nitrophosphate fertilizer.

Abstract

The invention provides an alginic nitric phosphate fertilizer and a preparation method thereof, belongs to the technical field of agricultural fertilizers, and specifically relates to a novel fertilizer which is capable of promoting crops to grow, improving the quality of crops and also changing the condition of soil hardening. The alginic nitric phosphate fertilizer comprises a nitric phosphate fertilizer and alginic acid, wherein the nitric phosphate fertilizer accounts for 1%-15% of the total weight, while the alginic acid accounts for 2%-5% of the total weight; the content of the active ingredients of the nitric phosphate fertilizer is 40%, while the content of nitrogen of the same is 27.5%+/-1.5%, wherein nitric nitrogen accounts for 25% and ammonium nitrogen accounts for 75%; the effective P2O5 of the nitric phosphate fertilizer is 11.5+/-1.5%, wherein water soluble phosphorus accounts for 70% and citric acid soluble phosphorus accounts for 30%; and the nitrogen-phosphorus ratio in the nitric phosphate fertilizer is 2: 1. The alginic nitric phosphate fertilizer is mainly applied to the aspect of agricultural fertilizers.

Description

technical field [0001] The seaweed nitrophosphate fertilizer and the preparation method of the invention belong to the technical field of agricultural fertilizers. Background technique [0002] Usually industrially produced chemical fertilizer products, nitrophosphate fertilizer, contain a large number of elements such as nitrogen, phosphorus and potassium needed for crop growth, which can greatly promote the growth and increase of crop production, but it also causes soil compaction, decline in fertility, decline in the quality of agricultural products and lack of trace elements. Waiting is not enough. [0003] Alginic acid contains seaweed polysaccharides, quinone groups, polyphenols, mannitol, betaine, highly unsaturated fatty acids, etc. and a variety of natural plant growth regulators with high biological activity such as cytokinins, gibberellins, auxins and Abscisic acid, etc., also contains more than 40 kinds of mineral elements such as potassium, calcium, magnesium, ...
