Embodiment 1

[0042] An organic fertilizer with an insect-resistant function is prepared through a production method comprising the following steps:

[0043] (1) Preparation of stockpiles

[0044] Mix fresh chicken manure and hay (or branches, straw, etc.) according to the weight ratio of 3-4.5:1-1.5, and then dry it until the moisture content reaches 55%-60%.

[0045] (2) Preparation of fermentation liquid bacterial agent

[0046] Self-prepared composite fermentation liquid bacterial agent by volume percentage, consisting of the following components: Bacillus licheniformis ABTNL-1 bacterial liquid 15~20% (bacterial liquid concentration 10% 8 ~10 9 CFU·ml -1 ), Bacillus subtilis ABTNL-2 bacterial liquid 10~15% (bacterial liquid concentration 10 8 ~10 9 CFU·ml -1 ), Bacillus thermospheroidus ABTNL-3 bacterial liquid 10~15% (bacterial liquid concentration 10 8 ~10 9 CFU·ml -1 ), Bacillus thuringiensis ABTNL-4 bacterial liquid 15~20% (bacterial liquid concentration 10 8 ~10 9 CFU·ml...

Embodiment 2

[0053] Step 1: Build a chicken manure static compost. The method is to manually mix the pretreated corn stalks, hay and fresh chicken manure with a shovel in a certain proportion (adjust the raw material C / N between 20 and 30), and adjust its moisture content (55% to 60%) to control It is advisable to hold a ball of chicken manure raw materials tightly with your hands, no liquid will flow out, and it will not disperse after you let go.

[0054] Step 2: Selection of bacterial solution

[0055] Bacillus licheniformis ABTNL-1 bacterial liquid 36.5ml (bacterial liquid concentration 10 9 CFU ml-1), Bacillus subtilis ABTNL-2 bacterial liquid 36.5ml (bacterial liquid concentration 10 9 CFU·ml-1), Bacillus thermosphaeroides ABTNL-3 bacterium liquid 36ml (bacterial liquid concentration 10 9 CFU ml-1), Bacillus thuringiensis ABTNL-4 bacterial liquid 36ml (bacterial liquid concentration 10 9 CFU·ml-1), Bacillus amyloliquefaciens bacterial liquid 25ml (bacterial liquid concentration 1...

Abstract

The invention discloses an insect-resistant bio-organic fertilizer and preparation method thereof. The preparation method mainly comprises two steps, step 1, complex fermentation of eight bacteria agents for improving fermentation efficiency, wherein the first four bacteria agents are thermophilic functional bacteria and can improve temperature peak and prolong duration of high temperature of compost through synergistic effect, and absence of any one of the first four bacteria agents may cause reduction of the duration of high temperature; the latter four bacteria agents are mesophilic functional bacteria, and can accelerate temperature rise on the basis of sufficiently degrading organics so as to enable the compost to be in high temperature phase in advance; step 2, mixing of bacillus thuringiensis ABTNL-4 for improving insect resisting effect of the compost. According to the invention, preparation efficiency can be improved, and the insect-resistant bio-organic fertilizer can be produced.

Description

technical field [0001] The invention relates to a bio-organic fertilizer with an anti-insect function and a preparation method thereof, belonging to the field of agricultural biotechnology. Background technique [0002] Chemical fertilizers have played a huge role in the development of agricultural production in my country, but long-term application in the soil is likely to cause adverse effects such as soil compaction, nutrient loss, and pH imbalance. Plant diseases and insect pests occur, resulting in poor quality agricultural products. [0003] Bio-organic fertilizers have received renewed attention due to their complete nutrient elements, diverse microbial populations, and their advantages of improving soil, improving resistance to diseases and insect pests, and improving the quality of agricultural products. Bio-organic fertilizer is a stable and harmless final product formed by organic waste fermented by microorganisms at high temperature. It is an environmentally frie...
