CN104541984A - Culture compost for industrial production of grifola frondosa - Google Patents

Abstract

The invention provides culture compost for industrial production of grifola frondosa. The culture compost consists of wood shavings, brans, cotton seed hull, corn flour and shell fossils. By the culture compost for industrial production of the grifola frondosa, the production period can be controlled within 70 days in an industrial production process of liquid fungus species, the quality of the grifola frondosa is high, and the biological efficiency is high.

Description

A kind of grifola frondosus factorial praluction composts or fertilisers of cultivating

Technical field

The present invention relates to Edible Fungi field, relate to a kind of grifola frondosus factorial praluction composts or fertilisers of cultivating specifically.

Background technology

Grifola frondosus has food, medicinal edible fungus concurrently, and because of its delicious food, nutrition, health care, deeply by consumers, also other mushroom series products are higher relatively for the selling price of fresh grifola frondosus.China started to carry out artificial domesticating cultivation to grifola frondosus the eighties in 20th century, and in Hebei, Zhejiang Province has and cultivates production on a small quantity, annual production 8000-10000 ton.

In recent years, the production technology of edible fungi liquid strain is applied to day by day in Edible Fungi, it is advantageous that, mycelium grows be in the conditions such as more suitable temperature, acid-base value, oxygen and C/N ratio in fermentation tank under; The metabolic waste that respiration produces can be discharged in time; A large amount of mycelium can be produced at short notice; During liquid spawn access solid culture medium, have mobility, easily disperse, sprout the features such as fast, the Edible Fungi mode that thus the liquid spawn mode of production is more traditional has larger superiority.

But the grifola frondosus mode of production of Present Domestic mostly is seasonal family workshop type, and factory culture is less, and scale is less, and there is the shortcoming that cultivation period is long, biological efficiency is low, regularity is poor, mushroom product commodity is bad; The biological property that grifola frondosus is intrinsic, also makes the cultivated species production cycle longer, thus makes grifola frondosus production cost be much higher than other mushroom kinds.

Summary of the invention

The object of the present invention is to provide a kind of grifola frondosus factorial praluction composts or fertilisers of cultivating, this composts or fertilisers of cultivating is made up of following component:

Wherein the particle diameter of wood chip is 2-6mm, and the particle diameter of wheat bran is for being less than 4mm, and cotton seed hulls is mesochite or medium staple, and the particle diameter of corn flour is less than 2mm, and the particle diameter of shellfish fossil is less than 2mm;

Wherein the water content of said components is all less than 15%;

Wherein ratio described above is weight percentage.

Each component, when applying, mixes, then adds water by a kind of grifola frondosus factorial praluction composts or fertilisers of cultivating of the present invention, and control water content at 64.0-66.0%, after sterilizing, pH controls at 6.7-7.3.

During application, the cultivation bag specification of suggestion is 17*33cm, and charge controls at 1100-1200g.

A kind of grifola frondosus factorial praluction composts or fertilisers of cultivating of the present invention, by the optimization combo between materials multiple in planting material, under the prerequisite ensureing biological efficiency, quality, substantially reduces the production cycle, thus reduces production cost, increase economic efficiency.In liquid spawn factorial praluction process, the production cycle can be made to control within 70d, and the product quality of grifola frondosus is high, biological efficiency is high.
