AI Technical Summary

Technical Problem

Traditional chemical fertilizers cannot fully promote soil enzyme activity in peony cultivation, affecting nutrient absorption, resulting in stunted plants, low flower quality, and soil compaction, leading to low fertilizer utilization. Existing microbial agents and nano-carbon liquid compound fertilizers cannot meet the needs of various fertilizer elements.

Method used

A composite compost of peony nanocarbon liquid EM microbial inoculant was prepared by using Streptomyces flavus, Bacillus stolonifera, sulfur-loving red oomycetes and nanocarbon liquid as a fermentation organic carrier. The synergistic fermentation improved the composting effect, provided a variety of nutrients, and improved the soil structure and physicochemical properties.

Benefits of technology

It significantly improves the utilization rate and nutrient content of organic compost, enhances soil enzyme activity, improves soil structure, increases the photosynthetic intensity and yield of peonies, and improves flower quality and economic benefits.

Abstract

The invention relates to the technical field of microbial complex microbial agents, in particular to peony nanocarbon liquid EM flora microbial agent composite compost which comprises the following raw materials in parts by weight: 2-4 parts of streptomyces microflavus zymophyte liquid, 2-4 parts of bacillus firmus zymophyte liquid, 1-3 parts of rhodovulum sulfidophilum culture liquid and 1-3 parts of nanocarbon solution. The peony fertilizer is prepared from 3-5 parts of kitchen waste filter residues, 10-12 parts of animal feather meal, 150-250 parts of decomposed cow dung, 80-120 parts of peanut straw, 2-4 parts of oil residues, 20-40 parts of feather meal, 10-12 parts of slaked lime, 2-4 parts of nitrogen, 20-40 parts of soybean meal, 20-40 parts of soybean curb residues, 4-6 parts of boric acid, 20-30 parts of phosphorus, 2-4 parts of magnesium sulfate, 2-4 parts of zinc oxide and 2-4 parts of potassium permanganate. Meanwhile, the granular structure of the soil is improved, the pH value of the soil is reduced, the EC value is increased, the activities of urease, sucrase, neutral phosphatase, alkaline phosphatase and catalase in the soil are improved, the photosynthesis of the peony is promoted, and the economic benefits of peony planting are increased.
