Description
Technical Field
The invention relates to the field of edible fungus cultivation, in particular to a method for cultivating straw rotting type edible fungus matrix by using pure corncobs.
Background
The edible fungus is a large-scale fungus, and the fruiting body of the edible fungus can be eaten by human beings or used as a medicine. At present, more than 90 kinds of edible fungi can be artificially cultivated or semi-artificially cultivated. According to the nutrition mode of the edible fungi, the edible fungi can be divided into 3 types of saprophytic, symbiotic and parasitic edible fungi, wherein hyphae decompose and assimilate dead plant residues by secreting various extracellular enzymes, nutrient edible fungi obtained from the decomposition and assimilation are called saprophytic type edible fungi, and most of the edible fungi cultivated artificially at present belong to saprophytic type edible fungi. The saprophytic edible fungi can be divided into wood-saprophytic edible fungi and grass-saprophytic edible fungi, the wood-saprophytic edible fungi have strong capability of decomposing lignin and wood fiber, the saprophytic edible fungi are mainly saprophytic wood, and the main wood-saprophytic edible fungi at present comprise agaric, mushroom, lucid ganoderma and the like; the straw rotting type edible fungi have poor or no capability of decomposing wood fiber and lignin, and mainly depend on degrading the nutrition of the herbaceous plant residues to rot the living stropharia rugoso-annulata, straw mushrooms, agaricus bisporus, agaricus blazei murrill and the like. The grass rotting type edible fungus strain is prepared by mixing rice husk, cotton seed husk, rice straw powder, miscellaneous wood flour and the like according to a certain proportion and adding some trace elements in an auxiliary manner and stirring. For example, the stropharia rugoso-annulata cultivated by rice husk and pure straw, the stropharia rugoso-annulata cultivated by beet leaf and the like; the rice straw and cow dung are used for cultivating the agaricus bisporus, the coprinus comatus, the agaricus blazei murill and the like. The pure corncobs are directly and simply used for cultivating the straw rotting type edible fungi, and related reports are not found.
Disclosure of Invention
The invention solves the problem of comprehensive utilization of corncobs and the problem of raw material sources of straw rotting type edible fungi. According to the nutrition contained in the corncobs, the growth nutrition requirements of the straw rotting type edible fungi can be completely met. The method can break the prior tedious operation of cultivating the straw rotting type edible fungi by utilizing the crop straws and adding other nutrient materials, and is more beneficial to popularization.
The technical scheme for solving the technical problems is as follows: a breeding method for improving the survival rate and the fighting capacity of fighting chickens comprises the following steps:
s1 preparation of corncob in the first step. When the straw rotting type edible fungi are cultivated, only corncobs are needed to be prepared, and other auxiliary materials are not needed to be prepared. Selecting corn cob which is produced in the same year and has no mildew.
S2 second step of corncob crushing. Crushing the prepared corncobs into corncob fragments and corncob powder of 1-2 cm, 1 mm-1 cm and less than 1 mm, and crushing the corncob fragments of 3 sizes: corn pellet dices with diameter less than or equal to 1 mm (10-15%), diameter less than or equal to 1 cm (15-20%), diameter between 1 cm and 2 cm (65-75%), and mixing.
S3 soaking/cooking corncob in the third step.
And (3) putting the corncobs of 3 specifications obtained by crushing the S2 into a bag, soaking the corncobs in clean water, or 3-5% of quicklime water for 3-7 days, or steaming the corncobs for 30 minutes, wherein water is required to be added for soaking or steaming until the corncobs just submerge.
S4 the fourth step is to replenish water into the corncobs. Randomly grabbing the soaked or steamed corncob fragments by a hand to tightly hold the corncob fragments with strength, and if continuous water drops can not be formed to fall, adding water to the corncob fragments according to the condition that the corncob fragments can have continuous water drops to fall; if a light grip is required to allow successive drops to fall, the relatively dry corn cob is increased to neutralize the moisture.
On the basis of the technical scheme, the invention can be further improved as follows.
Furthermore, in the step S2, the corncobs can be crushed into pieces with the diameter of less than 1 cm, the corncobs account for about 40% of the total corncobs, and the corncobs with the diameter of 2-3 cm account for 60%.
The beneficial effect of adopting the further scheme is that: the corncob crushing process is reduced, the corncob crushing process is reduced from 3 specifications to 2 specifications, and the labor cost is saved.
