Description
Technical field
The present invention relates to technical field of fertilizers, and in particular in a kind of high activity organic multicomponent microelement bio-feritlizer and
Preparation method.
Background technique
China largely uses chemical fertilizer for a long time, causes soil salt content excessively high, harmful ion concentration is excessive, structure
Property poor, easy to harden, soil fertility decline, crop growth is restricted, and soil, water pollution are got worse.Improvement soil,
It preserves the ecological environment and has caused the great attention of the Chinese government.
Improvement soil is mainly that application of organic fertilizers material promotes soil organic matter content at this stage；Or application calcium hydroxide tune
Acid soil is saved, calcium sulfate adjusts basic soil；Or application humic acid, but due to most of the production method of current humic acid
It is that the effect of active function of humic acid is rolled into a ball cannot really open up using the broken original powder produced of the warp such as weathered coal, peat, lignite
Existing, using effect is undesirable.The said goods have a single function, the granular material substantially simply blended, broadcast greatly together in seed manure
In the case that area is universal, it is not able to satisfy mechanical fertilization.Above-mentioned these problems cause China's soil improvement product quality not high,
Different crops and edaphic condition are difficult to adapt to, fertilizer nutrient utilization and improvement soil texture, Bu Nengji cannot be effectively improved
Tool application, increases recruitment cost.
