The fertilizer comprises an NPK compound fertilizer, trace elements and composite additives, wherein the composite additives comprise organic carbon, vinegar liquid, phosphate-solubilizing bacteria and humus soil. The fertilizer solves the problems of the existing methods of slow-release fertilizer film covering, cladding, capsule covering, coating and the like, the occurrence of crop plant diseases and insect pests can be reduced, the moisture content in the soil is regulated, the ventilation performance of the soil is improved, the fertilizer effect is maintained, harmful gas of the soil is regulated, the plant growth is promoted, and the microbes with plant growth promoting effect is increased. The fertilizer is an integral body containing various kinds of nutrition, and is not single-nutrition chemical fertilizer, the fertilizer also contains more than twenty kinds of crop necessary quality elements such as amino acids, humic acid, calcium, sulfur, zinc, iron and boron besides mass nutrition elements of nitrogen, phosphorus, potassium and the like, and the effects of regulating the soil and balancing the nutrition are also achieved.
Description
Technical field
The present invention relates to fertilizer field.More specifically, the special slow release synergy that grows tobacco is related to fertile and preparation method thereof.
Background technology
Tobacco needs to absorb more nutritive substance in a growth cycle, is not only nitrogen, phosphorus, the potassium that common fertilizer provides.Theoretical according to wooden barrel short slab, as lacked other nutrients, can not grow by normal growth, plant slight of stature, has a strong impact on output.Use in a large number due to chemical fertilizer increase yield significantly at present, cause pollution and the deterioration of the soil texture, natural ecological condition destroys.Especially the utilization ratio of fertility is low, and this not only wastes resource, and contaminate environment.
The rational application of fertilizer can provide tobacco necessary nutritive element, changes soil constitution, increases soil fertility, and increases soil organic substance.Thus the rational application of fertilizer growing to tobacco, promotes crop metabolism, improves tobacco yield per unit and plays conclusive effect.Carry out modification to fertilizer itself, exploitation Slow or controlled release fertilizer is effective measure that are the most efficient and convenient, that fundamentally can solve fertilizer loss problem.Slow release fertilizer has the advantages that nutrients release is slow, Crop is many, plant recovery of nutrient is high, uses slow fertilising and can also simplify work program, saving of work and time.Current slow release fertilizer both domestic and external is all generally the fertilizer being extended fertilizer efficiency by physical methods such as coating, parcel, packing, coatings, and by Quick-dissolving fertilizer and rubber latex, mixing the formed Wrapped fertilizer of agriculture and industry waste, these fertilizer costs are higher, and do not possess space and enrich, improve ground temperature, increase soil fertility, improve the features such as Soil structure, therefore develop a kind of cost-saving and preparation method is simple, the fertilizer special for tobacco of economic environmental protection is very important.
