A kind of preparation method of compound microbial bacterial fertilizer for root irrigation of peony

Abstract

The invention relates to a preparation method of a compound microbial fertilizer for peony root drenching. The method includes steps: adopting candida tropicalis for fermenting sweet potato residues and fruit wastes to obtain a fermented product I; mixing chicken manure, cow dung, biogas digester residues and wheat straws to realize natural fermentation to obtain a fermented product II; proportionally mixing the fermented product I and the fermented product II, performing inoculation of geotrichum candidum, bacillus megaterium and bacillus mucilaginosus, and fermenting to obtain a fermented product III; adding appropriate amount of a mixture containing mycorrhizal fungi spores of glomus intraradices and glomus mosseae, root internal and external hyphae and infected plant root segments, fish meal, zinc sulfate and bacillus subtilis HS5B5 bacterial liquid, and well mixing to obtain the compound microbial fertilizer for peony root drenching. According to peony growth nutritional and environmental demands, agricultural by-products are used as raw materials, and the prepared compound microbial fertilizer is capable of protecting peony roots and inhibiting pathogenic microorganisms and provides comprehensive nutrition for peony growth to promote growth and prolong flowering phase.

Description

technical field [0001] The invention relates to the field of preparation methods of microbial bacterial fertilizer, in particular to a preparation method of compound microbial bacterial fertilizer for peony root irrigation. Background technique [0002] Peony is a famous ornamental flower in my country. Its flowers are huge, graceful and luxurious, and are deeply loved by people. Peony grows in neutral or slightly alkaline soil, and it is not resistant to acid and heavy soil. Peony likes fertilizers, especially fertilizers with relatively complete elements such as nitrogen, phosphorus, and potassium. At present, the commonly used fertilizers are inorganic compound fertilizers or organic fertilizers such as livestock and poultry manure. Peony is a fleshy root, and the application of inorganic compound fertilizer must be applied far away from the main root. If the fertilization is too close to the main root, it will easily cause water loss in the peony root, which will affect...

AI Technical Summary

Problems solved by technology

Peony is a fleshy root, and the application of inorganic compound fertilizer must be applied far away from the main root. If the fertilization is too close to the main root, it will easily cause water loss in the peony root, which will affect the absorption of mineral elements. Long-term use of inorganic compound fertilizer will easily cause soil damage. Compaction and pollution of groundwater resources; the application of organic fertilizers must be retting and decomposing, and undecomposed organic fertilizers will ferment and release organic acids, which will cause the roots of peony to rot

In addition, during the growth process of peony, it is vulnerable to the influence of adverse environmental conditions and the infection of pathogenic microorganisms. The leaves, branches and rhizomes of peony can become the parts that are harmful to pathogenic microorganisms. The current solution is usually to apply chemical pesticides or Cut off diseased branches and leaves, etc., but long-term and large-scale application of chemical pesticides will easily cause pathogenic microorganisms to develop resistance, and at the same time cause environmental pollution and ecological balance damage
