Abstract

The invention discloses a compound fertilizer containing microelements. The compound fertilizer is prepared from the following raw materials by weight: 80-85 parts of rapeseed cakes, 40-45 parts of crop straws, 30-34 parts of tree leaves, 23-26 parts of rice husk,10-12 parts of rice straws, 10-12 parts of bamboo dust, 30-34 parts of activated carbon, 10-12 parts of chitosan, 80-90 parts of calcium magnesium phosphate fertilizer, 30-34 parts of urea, 13-16 parts of magnesium sulfate, 6-8 parts of zinc sulfate, 2-3 parts of copper sulfate, 3-4 parts of ammonium molybdate, 1-2 parts of borax, 2-3 parts of polyvinyl alcohol, 1-2 parts of sulfur, 3-4 parts of an EM microbial agent, 4-6 parts of a coating film and a proper amount of water. The fertilizer provided by the invention is an organic-inorganic special fertilizer integrating organic materials and inorganic nutrients. The prepared fertilizer contains a lot of macroelements such as N, P and K, and contains a certain proportion of medium and microelements. Meanwhile, the compound fertilizer combines the growth fertilizer requirement rule of the plants, is reasonable in raw material proportions, is more comprehensive and balanced in nutrients, and has relatively high scientificity.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound fertilizer containing trace elements and a preparation method thereof. Background technique [0002] From ancient times to the present, agriculture has played an important role in our country, and fertilizers play a decisive role in the growth of crops, so our country is also a big country in the use of fertilizers. At present, my country mainly uses chemical fertilizers, and the amount of chemical fertilizers used is also increasing, and the varieties used are mostly unit nitrogen fertilizers, while the use of multi-element fertilizers containing phosphorus and potassium elements is relatively small, resulting in soil hardening and the ability to retain water and fertilizer. Phenomena such as weakening not only waste fertilizers, but also increase the burden on farmers, and also have a certain impact on the environment. Our country has always advocated the rapid a...
