Special basal fertilizer used in ecological tobacco leaf plantation

Abstract

The invention discloses a special basal fertilizer used in ecological tobacco leaf plantation. The invention belongs to the technical field of organic fertilizers. The special basal fertilizer used in ecological tobacco leaf plantation comprises components of, by weight: 19 to 23% of fermented cake fertilizer, 43 to 47% of biogas residue, 17 to 21% of common calcium superphosphate, 2.3 to 2.7% ofpotassium nitrate, 0.27 to 0.32% of borax, 0.8 to 0.9% of zinc sulfate heptahydrate, 9.5 to 9.9% of potassium sulfate, 0.05 to 0.15% of potassium humate, and 0.64 to 0.68% of mixed microbial manure. The basal fertilizer is prepared through steps that: (1) cake fertilizer and biogas residue are dried and crushed, such that a basic mixture is obtained; (2) the mixed microbial manure is added; and (3) common calcium superphosphate, potassium nitrate, borax, zinc sulfate heptahydrate, potassium sulfate, and potassium humate are added. With the basal fertilizer provided by the invention, soil micro ecological environment can be repaired or protected, tobacco plant disease resistance can be improved, quality of fire-cured tobacco can be improved, and ecological tobacco production can be continuously and healthily developed.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to a base fertilizer required for planting ecological tobacco leaves. Background technique [0002] The application of organic fertilizer is to improve the quality of tobacco leaves, maintain and maintain soil fertility, improve and improve the quality of tobacco leaves and improve the ecological environment, which has been theoretically recognized by the prior art. Many studies have proved that the application of cake fertilizer can coordinate the internal chemical components of tobacco leaves and improve the quality of tobacco leaves; the application of organic fertilizer or bio-organic fertilizer can increase the total amount of microorganisms in the soil of tobacco fields, improve soil physical and chemical properties, enhance soil enzyme activity, and improve the quality of fertilizers. Utilization rate, reduce environmental pollution, etc., and can impr...

AI Technical Summary

Problems solved by technology

Long-term application of chemical fertilizers leads to soil compaction, deterioration of the soil ecological environment, and the decline in the intrinsic quality of tobacco leaves and the low utilization rate of the cigarette industry, etc.

At present, there are many studies on the preparation methods of organic fertilizers, such as organic fertilizers, green organic compound fertilizers and their manufacturing methods, but none of them can be effectively used in ecological tobacco planting
