When do you plant the ear?

Auricularia auricula is one of the main vegetables in the summer high temperature season in southern China. Its leaves contain a variety of vitamins and calcium and iron, and are cultivated as vegetables. Fruit juice can be used as a harmless food colorant, but it is rarely cultivated and has been listed as a rare and special vegetable. There are many plants in the north and south of our country, and there are wild ones in the south. Let's take a look at when to grow Auricularia auricula.

When will the fungus be planted?

Auricularia auricula is generally sown in April and harvested in June. It can usually be sown and cultivated in the open field when the temperature is above 20 ℃, and those mainly harvesting tender stems and leaves enter the harvest period about 50 days after sowing. Auricularia auricula is resistant to high temperature and humidity, and generally grows in loose and fertile sandy soil. The optimum temperature for seed germination is about 25 ℃, and the optimum temperature for plant growth is 25-30 ℃. Soil moisture is needed during the whole growth period. Some varieties have strict requirements for high temperature and short days, and most varieties are not strict about sunshine.

Sowing method of agaric vegetable

1. Soil preparation and fertilization: Auricularia auricula vegetables should be prepared and fertilized before sowing, about 5000 kg of mature and high-quality crude fertilizer should be applied per mu, and then ploughed and turned into beds with a width of 1-1.2 meters. When sowing in spring, in order to increase the ground temperature, plastic film mulching can be used to bake the ground one week before sowing. The seeds can only be sown when the local temperature is more than 15 ℃.

2. Soaking seeds to promote sprouting: the seed shell of Auricularia auricula is thick and hard, so you should soak the seeds before sowing. The seeds can be soaked in 50 ℃ water for 30 minutes, then soaked in warm water of 28 ℃ for 6 hours, scrubbed clean, moisturized and germinated at 30 ℃. When the seeds are white, they can be sown.

3. Sowing method: strip sowing can first open a ditch in the border, with a depth of 2 cm to 3 cm, a width of 10 cm to 15 cm, and a distance of 20 cm. After sowing, hold the border flat, after a little suppression, water according to the border, so that the water can wet the surface of the border. Sowing can first pour the bottom water according to the border, and then sprinkle 0.5 cm thick fine soil after the water seeps, then sow, and then cover 1.5 cm thick fine soil after sowing, and then cover with plastic film to keep warm and moisturizing. Generally, seedlings can emerge after 3-5 days.

Planting techniques of Auricularia auricula

The main results are as follows: 1. The planting of Auricularia auricula is that the row spacing of feeding leaves is 40 cm, the plant spacing is 30 cm, and there are 5 plants per hole, while the row spacing of feeding tender shoots is 15 cm × 30 cm, and there are 3 plants per hole.

2. Water and fertilizer management: Auricularia auricula should keep the soil moist and watered at the right time after emergence. Timely pursuit of human feces and urine after each harvest, 50 kg per mu, or 10 kg of urea, drainage and waterlogging prevention should be timely in the rainy season.

3. Harvest tender shoots: the harvested tender shoots of Auricularia auricula leave 3-4 leaves when the seedling height is 30-35 cm, and then 2 strong and exuberant lateral buds are selected to form shoots, and the rest are picked. After 2 shoots were harvested, 2 or 4 strong lateral buds were left to form shoots, and the rest were removed. In the peak growth period, 5-8 strong lateral buds can be selected to form shoots. Buds should be picked at any time in the middle and later stages. At the end of harvest, 1 or 2 strong lateral buds can be left to form shoots.

4. Harvesting leaves: when harvesting leaves of Auricularia auricula, the vine should be set up and the backbone vine should be selected. generally, the strong lateral buds at the base should be selected to form a vine. When the backbone vine grows to the top of the frame, pick the heart, and then leave strong lateral buds from the base of the backbone vine to form a vine. At 40-50 days after sowing, tender leaves are generally harvested every 15-20 days, 10-15 days in the middle growth stage and 10-17 days in the later stage.

5. Pest control: the pest damage of Auricularia auricula is very small, and it only occurs in a few continuous wet areas. The diseases include brown spot, gray mold, etc. at the initial stage, 72% Kelou wettable powder can be sprayed 600 times, or 75% chlorothalonil wettable powder 1000 times, or 70% methyl topiramate wettable powder 1000 times, sprayed once every 5 days and 2 times in a row.
