Problems solved by technology

[0002] With the continuous improvement of living standards, people pay more and more attention to food safety. The growth conditions of crops as the basic raw materials of food are particularly important. At present, the fertilizers used for crops mainly include chemical fertilizers and biological fertilizers. Chemical fertilizers are easy to cause soil compaction. and harmful substance residues in crop fruits; while the existing biological fertilizer products are not comprehensive in composition, bio-organic fertilizer is only the compound of bacteria and organic matter, the compound of inorganic fertilizer N, P2O5, K2O and organic fertilizer, lack of compound with new polymer materials ;Biological bacterial fertilizer is only one-sided biological bacterial agent, mixed with organic and inorganic N, P, K, and lacks the compounding of excellent polymer carrier, which is not good in water retention, adhesion, controlled release, etc., so the fertilizer efficiency is low. Large loss
[0003] Disadvantages of the above products: In the case of overcoming simplification and incomplete nutrition, the shortcomings of blind application, large loss, and inability to perform controlled release in the time range cannot be overcome, resulting in unequal fertilization effect and economic efficiency, and large loss. Pollution of surrounding environment and water system

[0058] N, P 2 o 5 , K 2 O content: 50%×12%+16%×12%+60%×12%=15.12%≥15%:

[0059] Organic matter content: 65%×50%+40%×8%=35.7%≥35%.

[0060] The marine polysaccharides used in this embodiment, the raw materials include the following components, according to the mass percentage of each component: shrimp shells or crab shells or shrimp shells and crab shells 30-70%, kelp, Eucheuma, asparagus, Macr...

Embodiment 2

[0087] The difference between the marine polysaccharide organic-inorganic compound controlled-release fertilizer of the present embodiment and the embodiment 1 is that:

[0088] The mass percent by each component in the raw material is respectively:

[0089] Marine polysaccharide 2%, urea 13%, superphosphate 11%, compound potassium salt 14%, seaweed powder 35%, high-temperature puffed chicken manure 25%, beneficial bacteria: nitrogen-fixing bacteria, colloid bacillus total content:

[0090] N, P 2 o 5 , K 2 O content: 50%×13%+16%×11%+60%×14%=16.66%≥15%

[0091] Organic matter content: 65%×40%+40%×25%=36%≥35%

[0092] The difference between the production process of the marine polysaccharide organic-inorganic compound controlled-release fertilizer of this embodiment and the production process of Example 1 is that:

[0093] The (6) grading process is omitted, and the finished product is suitable for fertilization on the ground by a machine, but not in the air by an aircraft...

Embodiment 3

[0095] The difference between the marine polysaccharide organic-inorganic compound controlled-release fertilizer of the present embodiment and the embodiment 1 is that:

[0096] According to mass percentage, raw material formula is:

[0097] Marine polysaccharide 1%, urea 14%, superphosphate 10%, compound potassium salt 15%, seaweed powder 45%, high-temperature puffed chicken manure 20%, beneficial bacteria are: nitrogen-fixing bacteria, colloid bacillus, total content:

[0098] N, P 2 o 5 , K 2 O content: 50%×14+16%×15%=17.6%≥15%;

[0099] Organic matter content: 65%×45%+40%×20%=37.25%≥35%;

[0100] The difference between the production process of the marine polysaccharide organic-inorganic compound controlled-release fertilizer of this embodiment and the production process of Example 1 is that:

[0101] The (7) coating process is omitted, and the finished product is specially used in highly acidic soil.

Abstract

The invention relates to a marine polysaccharide inorganic and organic composite controlled release fertilizer and a process for producing the same, belonging to the technical filed of fertilizer for corps. The marine polysaccharide inorganic and organic composite controlled release fertilizer comprises the following raw materials: 0.5-10wt% marine polysaccharide, 8-15wt% urea, 10-14wt% calcium superphosphate, 6-15wt% complex potassium salt and 30-65wt% seaweed meal, nitrogen-enriched bacterium and bacillus mucilaginosus are used as effective microbes, and others are common household organic fertilizers. The process comprises the following steps: (1) weighing the raw materials in certain mass percent; (2) homogenizing the raw materials for 10-20min; (3) granulating by disc atomizing; (4) drying the particles obtained by the step (3); (5) cooling the dried particles by normal temperature air cooling; (6) grading the cooled particles by a rotary screen; (7) coating the product surface with mixed water solution spray of marine polysaccharides and seaweed meals; and (8) measuring and packaging. The process has the advantage of scientific and reasonable process technique, and the produced fertilizer has the advantages of quick-acting, long-acting, synergy, water holding and controlled release. Various effects which can effect long time are achieved by fertilizing one time, so that the labor intensity of farmers is lightened, and the effectiveness and economy of fertilizing is improved.
