Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] 1. Embodiment:

[0016] 1. Material preparation

[0017] Distiller's lees compost is provided by Jinshagameng Agricultural Professional Cooperative, and its basic properties are as follows: organic matter (OM): 74.8%; total nitrogen (TN): 3.57%; total phosphorus (TP): 2.18% and total potassium (TK): 1.23% .

[0018] 2. Extraction preparation

[0019] Fully mix distiller's grains compost and water according to the mass ratio of 1:8, put it in a plastic bucket, then seal the plastic bucket and cover it, store it at 20°C-25°C for 7 days, and then filter it through double-layer gauze. The distiller's grains organic fertilizer extract was obtained and stored at 4°C for future use.

[0020] 3. Use of extract

[0021] In the growth stage of crops, the extract...

Abstract

The invention discloses preparation and application of an anaerobic vinasse organic fertilizer extracting liquid. A preparation method of the extracting liquid comprises the following steps of fully and uniformly mixing vinasse compost and water according to a mass ratio of 1:8, and putting into a plastic bucket; sealing the plastic bucket, and covering a cover; storing for 7 days at the temperature of 20 to 25 DEG C, and filtering by a gauze cloth. Compared with the extracting liquid prepared by the aerobic and direct extracting method, the extracting liquid prepared by the anaerobic method has the advantages that the contents of organic matter, whole nitrogen, whole phosphor and whole potassium are obviously increased, and the quick-dissolving property of nutrients is better; compared with the vinasse organic extracting liquid under the aerobic condition, the microorganism activity using the extracting liquid is lower, therefore the extracting liquid is especially suitable for crop root applying.

Description

technical field [0001] The invention relates to the preparation and application of an anaerobic distiller's grain organic fertilizer extract, and belongs to the technical field of compost extract. Background technique [0002] Compost extracts (compost tea or compost extracts) refer to the extracts of composted and decomposed organic materials extracted by different methods. At present, there are mainly two processes for the production of compost extract, but each has its advantages and disadvantages. One of them is aerated fermentation extracts compost (AFEC), which is characterized by short extraction time but requires external energy (oxygen, molasses, fish latex 0.5mol L -1 , humic substances, plant extracts, etc.); and the other is anaerobic extraction of compost extracts (Non-aerated fermentation extractscompost, namely NAFEC), which is characterized by no external energy supply, but the extraction time is relatively long. [0003] More and more studies have shown t...
