Abstract

The embodiment of the invention discloses a multifunctional soil compound fertilizer. The multifunctional soil compound fertilizer is prepared from the following components in parts by mass: 10 to 30parts of urea, 10 to 30 parts of monoammonium phosphate, 5 to 20 parts of potassium sulfate, 10 to 30 parts of humic acid, 0.2 to 4 parts of zinc sulfate, 0.2 to 5 parts of ferrous sulfate, 0.1 to 2 parts of boric acid, 0.2 to 5 parts of copper sulfate, 0.2 to 5 parts of manganese sulfate, 0.1 to 1 part of ammonium molybdate and 10 to 20 parts of biological bacteria. The multifunctional soil compound fertilizer fully utilizes oyster shells, river sand, light burnt magnesium, organic matters, the humic acid, the biological bacteria and various trace elements, so that balanced nutrition can be provided for crops; meanwhile, a sulfur coat is used to wrap various nutrients to realize slow release of the various nutrients, which improves the fertilizer utilization, reduces the fertilizer loss and increases the grain yield; and the multifunctional soil compound fertilizer can be widely applied to soil improvement and fertilization.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of soil fertilizers, in particular to a multifunctional soil compound fertilizer and a preparation method thereof. Background technique [0002] Chemical fertilizers have gradually become people's first choice due to their easy and quick application and rapid increase in production. While bringing huge benefits to agriculture, they also cause a series of negative effects, such as soil compaction and increasingly poor soil due to the reduction of soil organic matter. Continuing to use chemical fertilizers will inevitably affect the availability of soil and the food safety of crops. [0003] The nutrients needed for crop growth are all-round and indispensable. However, all existing fertilizers do not have the performance of all elements and multi-functions, but simple compounding. In particular, if the soil conditioner is mixed and used with a large amount of chemical fertilizers wit...
