Problems solved by technology

[0003] In order to solve the deficiencies in the prior art, the present invention provides a method for preparing compost for Agaricus bisporus in industrialized cultivation by using silage corn stalks, which solves the problem of using dry corn stalks to cause nutrient loss or using fresh corn stalks in the existing compost for cultivating Agaricus bisporus The stalks lead to problems such as short utilization time. After adding the treatment liquid, the problems of deterioration and mold that are easy to occur in the silage process are solved, and the workload of pre-wetting in the process of making compost is reduced, water is saved, the formula is reasonable, and Agaricus bisporus Preparation method of culture material with stable yield

Embodiment 1

[0019] Example 1: The preparation method of compost using silage corn stalks as the main raw material, wherein the weighing of various raw materials is the ratio of parts by weight. In order to meet the needs of factory production, the standard of 350-450 kg per part is selected. The raw material formula is: silage 70 parts of corn stalks, 24 parts of chicken manure, 2 parts of soybean meal, 5 parts of gypsum, 1 part of superphosphate;

[0020] The preparation method of culture medium is:

[0021] a Raw material pretreatment: crush the fresh corn stalks with a pulverizer, the length is 12-15cm, spray the treatment liquid accounting for 2% of the weight of the corn stalks, throw it into the middle layer of the silo, press it tightly, seal it, and carry out anaerobic fermentation. After 40 days PH is reduced to 4.2, and the silage corn stalks are obtained, and they are used for standby. After each feeding, the surface of the remaining stalks in the silo is sprayed with an aqueo...

Embodiment 2

[0027] Example 2: The preparation method of compost using silage corn stalks as the main raw material, wherein the weighing of various raw materials is the ratio of parts by weight. In order to meet the needs of factory production, the standard of 350-450 kg per part is selected. The raw material formula is: silage 80 parts of corn stalks, 24 parts of chicken manure, 2 parts of soybean meal, 5 parts of gypsum, 1 part of superphosphate;

[0028] Primary fermentation: The laboratory indicators are 72% moisture, 1.82% nitrogen, 0.6% ammonia, and PH8.5.

[0029] Secondary fermentation: The laboratory indicators are 66% moisture, 2.1% nitrogen, 0.018% ammonia, and PH7.7.

[0030] Other process steps are carried out according to embodiment 1 step.

[0031] Among them, the silage corn stalks used in the preparation of the compost were stored for 6 months. In the industrialized cultivation of Agaricus bisporus using this compost, the output of fresh mushrooms is 29 kilograms per s...

Embodiment 3

[0032] Example 3: The preparation method of compost using silage corn stalks as the main raw material, wherein the weighing of various raw materials is the ratio of parts by weight. In order to meet the needs of factory production, the standard of 350-450 kg per part is selected. The raw material formula is: silage 100 parts of corn stalks, 15 parts of duck / goose manure, 5 parts of soybean meal, 7 parts of gypsum, 2 parts of superphosphate;

[0033] Primary fermentation: The laboratory indicators are 73% moisture, 1.84% nitrogen, 0.6% ammonia, and PH8.5.

[0034] Secondary fermentation: The laboratory indicators are 68% moisture, 2.2% nitrogen, 0.02% ammonia, and PH7.6.

[0035] Other process steps are carried out according to embodiment 1 step.

[0036] Among them, the silage corn stalks used in the preparation of the compost were stored for 12 months. The industrialized cultivation of Agaricus bisporus using the compost prepared by the preparation method has an output of...

Abstract

The invention relates to a preparation method of compost for Agaricus bisporus industrialized cultivation using silage corn stalks in the technical field of edible fungus cultivation. The invention provides a method for preparing compost for factory-cultivated A. biscuitus by taking silage corn stalks and dung as main raw materials, pretreating the raw materials, mixing them, stacking them, and then undergoing primary fermentation and secondary fermentation. Among them, after adding zinc chloride, polyvinyl alcohol and other treatment solutions to silage corn stalks, the storage time is prolonged, and appropriate nutrients are added to quickly germinate bacteria, saving 90% of the water consumption for forage pre-wetting, and reducing 18% to 20%. The preparation cost of compost is low, the output is stable, and the economic benefits are obvious. The output of fresh mushrooms reaches 25 kg-30 kg per square meter.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a method for preparing culture material for industrialized cultivation of Agaricus bisporus by using silage corn stalks. Background technique [0002] Agaricus bisporus is a kind of edible mushroom that people like. In recent years, the sales of Agaricus bisporus in the domestic and foreign markets have increased significantly, which has prompted the continuous rise in the price of raw materials for compost of Agaricus bisporus. The traditional culture medium is mainly wheat straw, and the price of such raw materials has risen greatly. In the prior art, corn stalks are used instead of rice straw, wheat straw, etc. to prepare compost for Agaricus bisporus. At present, corn stalks are mostly harvested by machinery, which has a high water content, is prone to mildew and rot, cannot be stored in batches, and has serious loss of nutrients, so it is mostly used after...
