Biological organic composite coated fertilizer capable of activating soil and preparation method thereof

Abstract

The invention discloses a biological organic composite coated fertilizer capable of activating soil. The biological organic composite coated fertilizer is characterized by being prepared from the following raw materials in parts by weight: 10-13 parts of stellera chamaejasme powder, 20-24 parts of humulus lupulus, 33-36 parts of Chinese prickly ash, 50-57 parts of castor bean meal, 25-30 parts of nitrogen fertilizer, 15-20 parts of phosphatic fertilizer, 17-19 parts of potash fertilizer, 1-2 parts of sodium silicate, 17-21 parts of ammonium sulfate, 14-18 parts of calcium persulfate, 29-33 parts of carbamide, 1-2 parts of sodium borate, 8-11 parts of medical stone powder, 5-7 parts of EM fungicide, 7-9 parts of soil improvement agent and a proper amount of water. The biological organic composite coated fertilizer has balanced nutrition, contains nitrogen fertilizer, phosphatic fertilizer, potash fertilizer and microelements, also contains stellera chamaejasme powder, Chinese prickly ash and the like so that the residual fertilizer in the soil can be activated and used and good fertilizer efficiency is achieved; the soil improvement agent is added into the biological organic composite coated fertilizer, so that the biological organic composite coated fertilizer has functions of improving the fertilizer efficiency and promoting the nutrition absorption of the plant. The biological organic composite coated fertilizer is coated with carbamide, so that the biological organic composite coated fertilizer is good in slow-release effect and balanced in release of fertility; by virtue of the biological organic composite coated fertilizer, the cultivation cost is saved and the yield and quality of crops are improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a bio-organic composite coated fertilizer capable of activating soil and a preparation method thereof. Background technique [0002] Plants need a lot of nutrients to promote their rapid growth during the growth process. Different soils have certain effects on the growth of crops, which requires effective soil improvement. Existing fertilizers for soil improvement can only see the impact of fertilizers on crops, but cannot effectively improve the soil. Most of the soil is compacted due to the application of chemical fertilizers, and the poor soil is not effectively improved due to unreasonable fertilization, resulting in no harvest or poor harvest; especially the saline-alkali land occupies a considerable land area in my country and the world. It is too heavy to be cultivated, and some have invested a lot of money to improve, to discharge alkali and suppress salt, but with little effec...

The existing soil-improving fertilizers can only see the impact of fertilizers on crops, and cannot effectively improve the soil

Most of the soil is compacted due to the application of chemical fertilizers, and the poor soil is not effectively improved due to unreasonable fertilization, resulting in no harvest or poor harvest; especially saline-alkali land occupies a considerable land area in our country and even countries in the world. It is too heavy to be cultivated, and some have invested a lot of money to improve, to discharge alkali and suppress salt, but with little effect
