In recent years, the prices of agricultural means of production have increased year by year, the prices of agricultural products have increased slowly, and the economic benefits of agricultural production have been relatively low. In the past two years, the state has adopted direct subsidies for planting food crops, and farmers’ enthusiasm for grain production has greatly increased. . The area of ​​food crops has also increased greatly, but the utilization of crop stalks and oyster shells is not high. Part of the feed, most of it is abandoned. In order to make full use of the resource advantages of crop wastes and reduce the cost of cultivating edible fungi, replace the cotton seed husks to produce edible fungi, such as corn straw, corn cob, flax stalk, wheat straw, wheat bran, bean stalks, sunflower straw, etc. After smashing, all bags can be planted with edible fungi. And get higher economic benefits.
The principle of cultivation of cultivating materials is to make the ratio of carbohydrate to protein of the cultivating material reach or close to 25:1 in order to be suitable for the growth of edible fungi. The waste of most crops has high carbohydrate content and low protein content. , Ingredients can be added to some of the crops with higher protein content, such as soybean stalks, bean husk, flax straw, oil sunflower straw, etc. The protein content is higher, the appropriate amount to the proportion of 30-25:1, to meet the growth of mycelium , pulverize every 1000 kilograms according to the requirements of the preparation of a good culture material plus 20 kilograms of lime, 10 kilograms of gypsum, 1 kilogram of potassium dihydrogen phosphate, add water 1500 kilograms, fully stir evenly, so that the water content reaches 60-65%. Then, the bag is filled with polypropylene, and the material can be sterilized under high pressure or atmospheric pressure after being packed, and can also be cultivated after fermentation.
Choose the excellent oyster mushroom, mushroom, mushroom, and mushroom strains that are suitable for cultivation in our area, such as Jing 1, Zisporia, Pleurotus ostreatus, and Jin pin 1 commonly used in our district.
Inoculate in a culture room or room where disinfection with a mixture of formalin and potassium permanganate is sufficient. At about 25°C, germination can occur for 15-20 days, and the mycelium can be filled with bacteria. It is faster than cotton seedlings in the case of contamination with bacteria. It is rich in nutrients, C/N is reasonable, and the physical structure of cultivated materials is relatively loose. It can meet the needs of the hyphae-rich edible fungi hyphae well, and can decompose and utilize the crude fiber and nutrient components in the cultivated materials for the bacteria supply. Silk and mushroom growth. During the mushrooming process, the temperature change treatment and the use of scattered light were used to induce the formation of fruit bodies (small mushroom body), the temperature was maintained between 15-20 °C, and the relative humidity was maintained at about 95%. In addition, pests and diseases of edible fungi need to be controlled in time. Pick it once every 3-5 days.
The bioconversion rate of edible fungi using crop waste bags can reach more than 70%, and each 1,000 kg of feed can produce 700 kilograms of fresh mushrooms. Calculated at the average wholesale price of 3 kilograms per kilogram, minus the cost of production costs, the profit can be 1600. yuan. In addition, the use of crop waste bags for planting edible fungus has one of the biggest features is the fast growth, short cycle, a 600? greenhouse, vegetable or simple room can be produced twice a year in spring and autumn 20,000 kg of culture materials for production, At least 30,000 yuan in economic benefits.
