Planting methods and techniques of Auricularia auricula, with cost and profit analysis

After selecting the suitable varieties, the 10-year-old birch species were cut into 1-1.5m wood segments and inoculated after drying for 30 days; the electric drill was used to drill holes on the wood, and then sawdust bacteria were stuffed into the holes to ensure that the temperature was 20-28 ℃ and the humidity was 90-95%. The total cost of planting is 17300 yuan / mu, the profit of general land planting is 1-15000 yuan / mu, while that of hanging bag planting is 30-40, 000 yuan / mu.

I. the method of planting Auricularia auricula

1. Select varieties

(1) according to the shape, the varieties of Auricularia auricula can be divided into two categories: blossom shape and sheet shape, each of which has its own advantages. The output of blossom shape is relatively high, and the sheet shape is spread out, so it looks clean and easy to clean, so it is deeply loved by consumers and sells well in the market.

(2) the general selection of varieties can be planted according to the climate, geographical environment and market conditions of the region, and then combined with the adaptability and resistance of the varieties.

2. Planting environment

The main results are as follows: (1) the artificial cultivation of Auricularia auricula is mainly based on the wood segments of broad-leaved trees which are suitable for growth, and then provide a growing environment after artificial inoculation.

(2) choose a suitable place before planting, during which it is required to be sunny, warm and humid, clean and sanitary, and then select birch species suitable for planting about 10 years old, cut into wood segments of about 1-1.5m, and dry for about 30 days.

3. Inoculation and planting

The main results are as follows: (1) artificial inoculation is critical for planting. Firstly, the temperature is suitable for the growth of Auricularia auricula hyphae, while the temperature of 15-28 ℃ is more suitable. Wood chip type can be used for inoculation, that is, electric drill is used to drill holes on the sterilized wood section with a depth of about 2cm and a hole spacing of about 5X10cm.

(2) the sawdust bacteria are stuffed into the hole, and the surface is covered tightly with bark, which is beneficial to maintain the wettability. after inoculation, the wood sections are stacked into a certain shape to ensure that the temperature is between 20-28 ℃. The bacteria will start to grow only under the conditions of high temperature, high humidity, ventilation and ventilation.

4. Daily management

(1) the hyphae will begin to spread after survival, at this stage, the wettability of the place should be properly controlled between 90-95%, and the sun should be sufficient, the fungus should be ventilated and ventilated, and the fungus can be cross-built during this period.

(2) and to regularly spray an appropriate amount of water on the auricula, the frequency and amount of water need to be adjusted according to the actual situation, if the weather is dry, more water can be sprayed, and the rainy weather needs to stop spraying water, waiting for about 40-60 days, the fungus will grow one after another, and the growing fungus can be harvested many times in batches.

Second, the cost and profit analysis of planting Auricularia auricula

The main results are as follows: 1. The planting cost is also different with different planting methods, in which the production equipment cost of planting Auricularia auricula is about 1800 yuan, the labor cost is about 6250 yuan, and the total cost is about 17300 yuan / mu.

2. The profit of planting Auricularia auricula in the plot can reach about 1-15000 yuan / mu, while the profit of planting Auricularia auricula in hanging bags can reach about 30-40,000 yuan / mu.
