Embodiment 1

[0022] (1) Take fresh okra stalks and leaves (stalks with leaves), dry them in the sun until there is no moisture in the hand, and then crush them into particles with a particle size of 1 to 2 cm;

[0023] (2) mix okra stem and leaf particles, cottonseed hulls, wood chips, wheat bran, gypsum and lime according to the formula shown in table 1 to obtain a dry material (while setting a conventional formula as a comparative example), then add water until the water content reaches 68%, stir evenly to obtain culture substrate;

[0024] (3) Put the culture medium into a polyethylene plastic bag, tie the mouth of the bag tightly with a plastic rope, carry out normal pressure sterilization at 100°C for 12 hours, and cool naturally after sterilization;

[0025] (4) Inoculate according to conventional methods under aseptic conditions, and the strain is Xiuzhen mushroom Hangxiu No. 1 variety;

[0026] (5) After the inoculation is completed, place the bagged culture medium in an environme...

Embodiment 2

[0040] According to the method of embodiment 1, carry out the cultivation of raw material formula and pear mushroom, concrete formula is shown in Table 4, and comparison result is shown in Table 5

[0041] Table 4 The raw material comparison of embodiment 2 raw material formula and conventional formula

[0042]

[0043] Table 5 Comparison of mycelium growth, biotransformation rate and material cost between Example 2 and the conventional formula

[0044]

[0045] As can be seen from Table 4 and Table 5, adopting the raw material formula of Example 2, its biotransformation rate can reach 75.2%, that is, 1 kg of dry weight base material can produce 0.752 kg of pseudomonas fruiting body. Compared with the conventional formula, it has been improved by 6.5%, but the cost has been saved by more than 50%.

Abstract

The invention discloses a pleurotus geesteranus culture medium prepared from stems and leaves of okra. The culture medium consists of a dry material and water, wherein the dry material comprises the following components in percentage by weight: 45-65% of okra stem and leaf grains, 10-20% of cottonseed hull, 10-20% of wood bit, 10-15% of wheat bran or rice bran, 1-2% of lime and 1-2% of gypsum, wherein the okra stem and leaf grains are grains which are made by drying and crushing stems and/or leaves of okra, and the particle size of the grains is 1-2cm. When the culture medium is used for culturing pleurotus geesteranus, the fungus sprouting time is brought forwards for 2-8 days when being compared with that of an ordinary formula, the biotransformation efficiency of the pleurotus geesteranus can be 75.2%, and the output is increased by greater than 6.5% when being compared with the ordinary formula. As the stems and the leaves of the okra contain rich nutrient substances, a pleurotus geesteranus entity cultivated by using the culture medium is high in quality, and the crude protein, the crude fat and the total sugar content are remarkably increased when being compared with that of the ordinary formula.

Description

technical field [0001] The invention relates to a culture substrate of chrysanthemum pleurotus, in particular to a culture substrate of pleurotus osmanthus prepared from stems and leaves of okra. Background technique [0002] Pleurotus chinensis is a rare edible fungus species that is deeply loved by consumers. Its cultivation raw materials are mainly cottonseed hulls and miscellaneous wood chips. In recent years, with the continuous expansion of the cultivation scale of oyster mushrooms, the demand for cottonseed husks and miscellaneous wood chips has also continued to increase. First, the price of cottonseed husks is also rising, even as high as 2,500 yuan / ton, which makes the cultivation cost of mushroom growers rise sharply and the cultivation benefits gradually decline; second, a large number of forest resources are cut down, causing vegetation to be destroyed and natural disasters Frequent occurrence, deterioration of the ecological environment. Therefore also urgentl...
