Method for cultivating edible fungus by using discarded branches and leaves of urban greening

Abstract

The method of cultivating edible fungi by using the discarded branches and leaves of urban greening, at least one kind of urban greening branches and leaves among ginkgo, zelkova, magnolia or white birch is preliminarily sorted, washed, dried, crushed, mixed with nutrients and water, and stirred evenly , to make edible fungus culture material, put the edible fungus culture material into bags and carry out high-temperature sterilization. Flammulina velutipes common edible fungus. The invention uses the discarded branches and leaves of landscaping as raw materials, which not only effectively solves the problem of shortage of raw materials for cultivating edible fungi, but also reasonably solves the problem of waste disposal in current landscaping. The edible fungi cultivated by the invention are rich in nutrition, good in mushroom quality and high in yield ,with broadly application foreground.

Description

technical field [0001] The invention relates to a technology for cultivating edible fungi, in particular to a technology for cultivating edible fungi using discarded branches and leaves of urban afforestation. Background technique [0002] The carbon sources in traditional edible fungus culture materials are mainly cottonseed hulls, corncobs, straw, etc. These raw materials need to be purchased in large quantities, which greatly increases the cost of edible fungi and reduces planting benefits, which restricts the rapid development of the edible fungi industry. If cottonseed hulls are mainly used as compost, there will be the following disadvantages: First, the source of cottonseed hulls is limited by seasons, which are relatively sufficient in summer and autumn, and cannot be supplied in large quantities in winter and spring; It has become more and more scarce, and the price has changed from 0.2 yuan per catty to 0.85 yuan per catty; third, the operation process is complicat...

AI Technical Summary

Problems solved by technology

[0002] The carbon sources in traditional edible fungus culture materials are mainly cottonseed husks, corncobs, straw, etc. These raw materials need to be purchased in large quantities, which greatly increases the cost of edible fungi and reduces the benefits of planting, which restricts the rapid development of the edible fungi industry.

If cottonseed hulls are mainly used as compost, there will be the following disadvantages: First, the source of cottonseed hulls is limited by seasons, which are relatively sufficient in summer and autumn, and cannot be supplied in large quantities in winter and spring; It has become more and more scarce, and the price has changed from 0.2 yuan per catty to 0.85 yuan per catty; third, the operation process is complicated, and the labor and time costs are high

Corn cobs are also limited by seasonal and regional production, and the purchase price is about 0.4-0.9 yuan / catties, which increases the input cost of large-scale production

If the main component of the compost is straw, a large volume of wheat straw is needed to cultivate a small amount of edible fungi, and the cultivation effect is not good.

On the other hand, with the continuous advancement of my country's urban greening process, more and more urban greening wastes cannot be recycled reasonably, which not only causes serious pollution to the environment, but also causes a huge waste of resources

[0003] The patent literature with the application number CN201010267926.9 provides a culture medium for edible fungi, which contains magnesium sulfate, triacontanol, peptone, beef extract, etc. in its raw materials. This is a traditional method for cultivating edible fungi, and its disadvantages are The cost is too high; the patent document with the application number CN201010172606.5 provides a kind of edible fungus culture medium mainly made of waste cartons. Since the cartons have been processed in the papermaking process, the cellulose, hemicellulose and other components have been destroyed. , the carton can only be used as the base material, and supplementary materials such as peptone must be added to ensure the nutritional supply, which cannot significantly reduce the cost in practical applications; the patent document with the application number CN201010101915.3 provides a culture medium for edible fungi, and its formula is : Pine and Chinese fir sawdust, due to the high wax content on the surface of pine and Chinese fir sawdust, the sawdust should be sprayed for 20~60 days, which greatly prolongs the production cycle

[0004] The patent document with the application number CN200610135315.2 provides a method for cultivating rare edible fungi using the discarded branches of landscaping. This method is mainly used to cultivate precious fungi. The formula of the material does not describe the growth status of the edible fungus, making it impossible for people to know whether the method is effective; (2) The tree species listed in this method are mainly distributed in southern China, and cannot be widely used nationwide; (3) Rare strains are cultivated in this method, which is not easy to popularize; (4) In addition to waste branches as carbon sources, the formula listed in this method also includes wood chips and cotton seed hulls, which increases production costs
