Problems solved by technology

[0007] The inventor unexpectedly discovered through research that the adoption of the above-mentioned coating structure solved the technical problems of foaming and less addition of humic acid in the high-tower process, and the spray granulation of the activated humic acid-urea mixture can significantly improve the particle strength. To reduce the problem of particle pulverization, through the reasonable combination of the above active ingredients, the utilization rate of fertilizers can be improved, the soil can be effectively improved, the loose soil can retain water, and the yield and quality of crops can be improved. In particular, activated humic acid urea, loose soil concentrate and polyglutamic The acid components work together to solve the problems of humic acid activation and urea loss. It can inhibit the activity of urea enzyme, slow down the decomposition of urea, reduce volatilization, and gradually release nitrogen to prolong the fertilizer effect.

[0079] Experimental example 1 (field fertilizer effect test)

[0080] 1. Test location: Jiaolong Town, Linshu County, Linyi City, Shandong Province

[0081] 2. Basic conditions of the soil in the test site: The soil for the test is loam.

[0082] Peanut variety selection and seed treatment: Kehua No. 1 was selected; the seeds were dried before sowing. Test design:

[0083] 9 treatments were set up in the experiment, each treatment area was 50m 2 , each treatment was repeated 3 times, arranged in random blocks, and 9 experimental treatments totaled 27 plots. The blocks were set along the direction of soil fertility gradient, and the soil fertility was uniform. The specific treatment is as follows:

[0084] Treatment 1: blank control, no fertilization (CK);

[0085] Treatment 2: conventional fertilization control, application of common compound fertilizer (15-15-15) (T1), 40kg per mu;

[0086] Treatment 3: Apply the organic-inorganic compound fertilizer (T2) prepared in Ex...

Abstract

The invention relates to an organic-inorganic compound fertilizer containing active factors as well as preparation and application of the organic-inorganic compound fertilizer. The organic-inorganic compound fertilizer comprises a) a granular inner core, wherein the granular inner core comprises the following components: a first nitrogen fertilizer, a phosphorus fertilizer, a first potassium fertilizer, a medium and trace element fertilizer and a functional bag; and b) a coating layer covering the granular inner core, wherein the coating layer comprises the following components: humic acid, hydroxide, a second nitrogen fertilizer and a second potassium fertilizer. The organic-inorganic compound fertilizer provided by the invention is high in fertilizer utilization rate, and can effectivelyimprove soil, loosen soil, retain water, promote crop growth and improve crop yield and quality.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic-inorganic compound fertilizer containing active factors and its preparation and application. Background technique [0002] At present, 70%-80% of chemical fertilizer usage is wasted due to irrational use and unbalanced soil nutrition, resulting in low fertilizer comprehensive utilization rate, which not only causes huge economic losses but also leads to serious pollution of soil environment, atmospheric environment and water environment. . Excessive use of fertilizers and unreasonable agricultural fertilization structure lead to soil compaction, serious acidification, and imbalance of the micro-ecological environment. Soil compaction hinders the rooting of crops, reduces the utilization rate of fertilizers, and makes it difficult for crops to breathe. Production fell. [0003] The organic-inorganic compound fertilizer has the dual advantages of quick-acting and l...
