Embodiment 1

[0034] 1. Preparation of corn stalk oyster mushroom compost

[0035] Step 1: Use a corn stalk chopping and collecting machine to cut the corn stalks harvested from the corncobs into 1.0-2.0cm long sections.

[0036] Step 2: Sprinkle slaked lime powder of 3% by weight of corn stalks on the corn stalks, add water and stir evenly; the slaked lime powder used is calcium hydroxide powder prepared by adding water to quicklime about 2 hours before use. The amount of water used is: hold the corn stalks running water, but there is no large amount of water in the site; pile the corn stalks into a pile with a thickness of 0.8-1.0 meters, and ferment naturally.

[0037] Step 3, when the material temperature rises to 40°C, add 0.3% urea (urea needs to be dissolved in water and then sprayed when turning the material), 1% superphosphate, and 10% chicken manure based on the total weight of corn stalks, Stir evenly and build a heap for fermentation;

[0038] Step 4, when the temperature of t...

Embodiment 2

[0046] Step 1: Use a corn stalk chopping and collecting machine to cut the corn stalks harvested from the corncobs into 1.0-2.0cm long sections.

[0047] Step 2: Sprinkle slaked lime powder with 5% weight of corn stalks on the corn stalks, add water and stir evenly; the slaked lime powder used is calcium hydroxide powder prepared by adding water to quicklime within 24 hours before use. The amount of water used is: hold the corn stalks running water, but there is no large amount of water in the site; pile the corn stalks into a pile with a thickness of 0.8-1.0 meters, and ferment naturally.

[0048] Step 3, when the material temperature rises to 43°C, add 0.4% urea (urea needs to be dissolved in water and then sprayed when turning the material), 1% superphosphate, and 10.0% chicken manure based on the total weight of corn stalks, Stir evenly and build a heap for fermentation;

[0049] The shapes of the piles built are: the width of the bottom of the pile is 1.8-2.0 meters, the...

Embodiment 3

[0056] Step 1: Use a corn stalk chopping and collecting machine to cut the corn stalks harvested from the corncobs into 1.0-2.0cm long sections.

[0057] Step 2: Sprinkle slaked lime powder with 4% weight of corn stalks on the corn stalks, add water and stir evenly; the slaked lime powder used is calcium hydroxide powder prepared by adding water to quicklime about 3 hours before use. The amount of water used is: hold the corn stalks running water, but there is no large amount of water in the site; pile the corn stalks into a pile with a thickness of 0.8-1.0 meters, and ferment naturally.

[0058] Step 3, when the temperature of the material rises to 45°C, add 0.5% urea (urea needs to be dissolved in water and sprayed in when turning the material), based on the total weight of corn stalks, 1% superphosphate, 10% chicken manure, 2.0% bran, turn the material evenly, and build a material pile for fermentation;

[0059] The shapes of the piles built are: the width of the bottom of...

Abstract

The invention discloses a method for preparing an oyster mushroom culture material from corn straw. The method comprises the following steps of cutting the corn straw to the length of 1.0-2.0 cm; spraying slaked lime powder accounting for 3-5% of the weight of the corn straw, and carrying out watering, and uniform stirring; carrying out piling and fermenting until the material temperature is 40-45DEG C, and adding 0.3-0.5% of urea, 1% of calcium superphosphate and 10% of livestock and poultry manure to build a material pile for fermentation; when the temperature of the materials in the material pile is 70 DEG C, turning the material pile once every 3-4 days of heat-preservation fermentation, continuing the heat-preservation fermentation, and turning the material pile according to the interval of 3 days-2 days-1 day; for a pile turning method, taking down stockpile with the thickness of 10-20cm on the outer surface layer of the material pile, and performing gathering and disturbing toform a new pile core; and turning the stockpile in the raw material pile to the pile core to form a new material pile, and in the turning process, avoiding beating of stockpile. According to the method for preparing the oyster mushroom culture material from the corn straw, macromolecular organic substances are fermented and decomposed into simple substances which are easily absorbed by oyster mushroom hyphae at high temperature, harmful infectious microbes and worm eggs are killed at the same time, the prepared oyster mushroom culture material has mildewy fragrance or fragrant and sweet tasteand is environmentally friendly, low in cost and rich in resource, and mushroom bran can be used as feed or organic fertilizer.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a corn stalk oyster mushroom compost and a preparation method and application thereof. Background technique [0002] In recent years, with the sharp reduction in the number of herbivorous livestock such as cattle, horses, and donkeys, as well as the increasing efforts to ban straw burning and environmental protection, the comprehensive utilization of corn straw has become a social problem that plagues governments at all levels and farmers. problem. Straw returning to the field cannot be widely promoted because the failure of straw to degrade in a short period of time may easily cause soil moisture and nutrient loss. [0003] With the continuous expansion of edible fungi planting scale in recent years, the demand for raw materials for edible fungus cultivation has increased sharply. The crude protein content in cottonseed hulls, which is usually used...
