The present invention discloses a kind of tobacco special slow release synergy fertilizer and preparation method thereof, and the fertilizer includes nitrogen-phosphorus-potassium compound fertilizer, microelement and compound additive；The compound additive includes Organic carbon, vinegar liquid, phosphate solubilizing bacteria and peat.The fertilizer solves the higher method of the costs such as coating, package, packing, the coating of existing slow-release fertilizer, and can be reduced crop disease and insect and occur, adjust and keep soil moisture content, improve the gas permeability of soil and keeping fertilizer efficiency, the pernicious gas for adjusting soil, promote plant growth, increase the microorganism for promoting Effects on Plant Growth.The fertilizer is containing there are many synthesises of nutrient, it is not the single chemical fertilizer of nutrient, it is also rich in necessary to 20 various crops such as amino acid, humic acid, calcium, sulphur, zinc, iron, boron " Quality Element " other than the macronutrients such as nitrogenous, phosphorus, potassium, plays the role of adjusting soil balanced nutrients.
Description
Technical field
The present invention relates to fertilizer fields.More particularly, to a kind of tobacco special slow release synergy fertilizer and preparation method thereof.
Background technique
Tobacco needs to absorb more nutriment in a growth cycle, not only provided by common fertilizer
Nitrogen, phosphorus, potassium.According to barrel short board theory, such as lack other nutrients, can not normal growth and development, plant slight of stature, seriously affect
Yield.It is largely used due to chemical fertilizer increase yield significantly at present, causes the pollution and deterioration of the soil texture, natural ecological condition is broken
It is bad.The utilization rate of especially fertility is low, this not only waste of resource, but also pollution environment.
The rational application of fertilizer is capable of providing nutrient necessary to tobacco, changes soil constitution, increases soil fertility, and increases soil
Earth organic substance.Thus growth and development of the rational application of fertilizer to tobacco promotes crop metabolism, improves tobacco yield per unit area
Play conclusive effect.Fertilizer itself is modified, exploitation Slow or controlled release fertilizer be it is the most efficient and convenient, most can be from root
The effective measures of fertilizer loss are solved the problems, such as in sheet.With nutrients release, slow, crop absorbs more, plant recovery of nutrient height to slow release fertilizer
The characteristics of, labour program, saving of work and time can also be simplified by applying slow fertilising.Current slow release fertilizer both domestic and external is typically all to pass through
The physical methods such as coating, package, packing, coating extend the fertilizer of fertilizer efficiency, and by Quick-dissolving fertilizer and rubber latex, industrial or agricultural
Waste mixing is formed by Wrapped fertilizer, these fertilizer costs are higher, and does not have abundant gap, raising ground temperature, increase ground
Power improves the features such as soil texture, therefore develops a kind of save the cost and simple, the economic and environment-friendly fertilizer special for tobacco of preparation method
It is very important.
