Special slow release synergistic fertilizer for tobacco and preparing method of special slow release synergistic fertilizer

Abstract

The invention discloses a special slow release synergistic fertilizer for tobacco and a preparing method of the special slow release synergistic fertilizer. 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 [0001] The present invention relates to the field of fertilizers. More specifically, it relates to a special slow-release and synergistic fertilizer for tobacco and a preparation method thereof. Background technique [0002] Tobacco needs to absorb more nutrients in a growth cycle, not only nitrogen, phosphorus and potassium provided by ordinary fertilizers. According to the short board theory of wooden barrels, if there is a lack of other nutrients, it will not grow and develop normally, and the plants will be thin and small, which will seriously affect the yield. At present, chemical fertilizers are widely used due to significant increase in production, resulting in pollution and deterioration of soil texture and destruction of natural ecological conditions. In particular, the utilization rate of fertility is low, which not only wastes resources, but also pollutes the environment. [0003] Reasonable fertilization can provide essential nutrients for toba...

AI Technical Summary

Problems solved by technology

At present, slow-release fertilizers at home and abroad are generally fertilizers that prolong the fertilizer effect by physical methods such as coating, wrapping, encapsulation, and coating, and wrapped fertilizers formed by mixing instant fertilizers with rubber emulsion and industrial and agricultural waste. These fertilizers are expensive, and do not have the characteristics of rich voids, increased ground temperature, increased soil fertility, and improved soil structure. Therefore, it is very necessary to develop a cost-saving, simple preparation method, economical and environmentally friendly tobacco-specific fertilizer.
