Abstract

The invention discloses an environment-friendly slow releasing compound fertilizer which comprises the following raw materials by weight part: 20-40 parts of urea, 20-40 parts of ammonium dihydrogen phosphate, 30-50 parts of potassium phosphate, 0.4-0.5 part of sodium borate, 0.1-0.2 part of ferric chloride, 0.1-0.3 part of manganese ammonium phosphate, 0.3-0.4 part of potassium molybdate, 0.2-0.4 part of copper sulfate, 0.1-0.3 part of zinc sulfate, 8-10 parts of calcium chloride, 4-6 parts of magnesium sulfate, 8-12 parts of kieselguhr, 35-45 parts ofcoating material, 10-12 parts of bean pulp, 5-8 parts of rape seed cake, 10-15 parts of livestock manure, 5-6 parts of mushroom dreg, 5-10 parts of plant ash, 4-8 parts of peanut dreg, 10-20 parts of humic acid and 1-3 parts of biochar. The environment-friendly slow releasing compound fertilizer can efficiently control all elements to slowly release and can be easily degraded; the soil can be improved; the soil moisture can be kept; the environment can be protected.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an environment-friendly slow-release compound fertilizer. Background technique [0002] At present, there are many problems in the use of chemical fertilizers, such as: most of the fertilizers used are ordinary quick-acting chemical fertilizers, unreasonable fertilization, excessive fertilization, low utilization rate of chemical fertilizers, and excess fertilizers cause waste of resources, environmental pollution, and soil compaction Decrease the quality of agricultural products, etc. [0003] Compared with chemical fertilizers, slow-release fertilizers have many advantages, such as reducing nutrient loss and greatly improving fertilizer utilization efficiency, which has become a research hotspot in fertilizers. At present, the proportion of coated fertilizers in slow-release fertilizers is the largest, but the coating materials are mostly organic synthetic polymers, which ...
