Black-skinned chicken fir cultivation techniques, black-skinned chicken fir how much money per jin per mu how much investment

The large-scale artificial cultivation of black-skinned chicken fir has the advantages of low production cost, short cycle and high yield, which can meet the market demand of people. How to grow the black skin chicken fir fungus? The price of black skin chicken fir fungus is 35 yuan per jin, and the price will change in different regions.

The culture method of the black skin chicken fir includes the preparation of the mother seed, the preparation of the original seed, the preparation of the production seed and the artificial cultivation, which is characterized in that the preparation steps of the mother seed are as follows:

a. Under the aseptic condition, the spore of the fruiting body of Fir was isolated, and the fruiting body mycelium was obtained.

b. The fruiting body mycelium was transferred into the test tube with culture medium, and the mature mother seed was obtained by culture at 19 °21 °C for 10 ~ 15 days.

The culture medium is: wheat straw juice 1000ml, Agar 10g 15g, sucrose 25g.

The preparation method of the culture medium is as follows: 200g wheat straw is added, 1000ml distilled water is added, 30~40min is boiled gently, the juice is filtered after cooling, 25g sucrose and 10g Agar are added to the juice, heated and dissolved, and the volume is fixed to 100ml.

The culture medium of the original seed and the producing seed contains one or more compositions of wheat straw, peanut shell, chestnut shell, wheat straw and sorghum straw with lignin content more than 20%. The composition of the preferred culture medium of the original species is: wheat straw 65%, chestnut shell 32%, limestone powder 3%, water content 60% 65%; or sorghum straw 8%, wheat straw 61%, chestnut shell 28%, limestone powder 3%, water content 60% 65%.

The artificial cultivation process includes bagging, sterilization, inoculation, culture and soil covering cultivation, specifically as follows: the culture material is bagged and sterilized under 1.5kg/cm2 pressure for 3 hours, then the bacterial rod is prepared by cooling inoculation, and the bacterial rod is placed in the culture room to mature and transferred to soil covering cultivation.

After the mycelium of black-skinned chicken fir is physiologically mature, the stick is removed from the plastic bag and cultivated with soil-covered 7~9cm. The PH of the culture soil is 6.5-7.0, the culture temperature is 22-26 °C, the humidity is 75%-80%, and the stalk can be harvested and dried when the stalk reaches 10~15cm. In addition, in order to better stimulate the formation and development of fruiting bodies, the diurnal temperature difference during soil mulching cultivation was controlled at 10: 12 ◦ C.

How much does the black skin chicken fir fungus invest per mu? It depends on whether there is a suitable greenhouse, about 200000 if there is one, and at least 300000 if not.
