Novel chemical fertilizer

Abstract

The invention discloses novel chemical fertilizer, prepared from, 50-80 parts of urea, 15-30 parts of plant ash; 3-5 parts of rare earth addition, 10-15 parts of monoammonium phosphate, 3-7 parts of magnesium sulfate, 3-7 parts of calcium sulfate, 6-12 parts of potassium chloride, 3-5 parts of single superphosphate, 10-16 parts of carbon,phosphorus and potassium, 5-10 parts of heptahydrated ammonium molybdate and 5-8 parts of agricultural rare earth. The fertilizer is used in crop yield increase fertilizer, with fine functions to improve crop weight and yield.

Description

technical field

[0001] The invention relates to the technical field of fertilizers, in particular to crop fertilizers. Background technique

[0002] Since the synthesis of chemical fertilizers in the 19th century, chemical fertilizers have been widely used because they can greatly increase the yield of crops. However, with the wide application of chemical fertilizers, its shortcomings have gradually been recognized by people: 1) The fertilizer efficiency time period of chemical fertilizers is not high, and the amount of use is large; 2) Excessive use of chemical fertilizers will destroy the structure of the soil and acidify the soil 3) Chemical fertilizers remain in the crops, thus affecting human health. Obviously, such chemical fertilizers do not meet the requirements of the times, and people urgently need a new type of chemical fertilizer with high efficiency and harmlessness.
