Planting methods of Auricularia auricula

With the deepening of people's understanding of Auricularia auricula, more and more people will like the uniqueness of Auricularia auricula, and planting Auricularia will become a project for farmers to get rich in the future. Let's take a look at it with the editor.

Planting methods of Auricularia auricula

1. Variety selection

The varieties with strong growth potential, many branches, high temperature resistance, drought resistance, moisture resistance, high nutritional value, thick stem, thick leaves, soft, smooth and fleshy leaves were selected. Like Auricularia auricula.

2. Soaking seeds to accelerate germination

The seed coat of Auricularia auricula is hard and it is difficult to germinate, so it must be accelerated before sowing. Soak the seeds in 35 warm water for 1-2 days, remove and germinate at 25-30 ℃. In about 4 days, the seeds can be sown after "whitening".

3. Soil preparation and fertilization

Before sowing, the mature organic fertilizer 3000-4000kg and superphosphate 50kg were applied every 667 m, turned deeply and raked flat to make a flat bed. The width of border is 1.2m. And build the shed in time.

4. Cultivation methods.

① direct seeding cultivation. The seeds used for direct seeding feeding seedlings were 6kg / mu and sowed. In order to facilitate seedling emergence, the seeds can be soaked for 1-2 days before sowing and germinated at a temperature of about 30 ℃. About 40 days after sowing, the seedling height is 10-15 cm and can be harvested.

The seedlings were raised and transplanted with ②. Make a good seedbed, sow dry seeds, and emerge in 3-5 days at an appropriate temperature of about 28 ℃. If the ground temperature is too low, you should speed up germination and sow seeds. Proper low temperature was controlled at seedling stage, and 4-5 true leaves were planted. The row spacing of tender shoots is 20 cm 25 cm, the plant spacing is 15 cm 20 cm, the row spacing of tender leaves is 60 cm, the plant spacing is 25 cm 35 cm, and the seedling protection is 3000 cm / mu.

Growth habits of Auricularia auricula

Auricularia auricula is produced in tropical Asia, which is planted in the north and south of China, and wild in the south. Resistant to high temperature and humidity, it generally grows in loose and fertile sandy loam. Generally, the optimum temperature for seed germination is about 25 ℃, and the optimum temperature for plant growth is 25-30 ℃. Soil moisture is needed in the whole growth period. Some varieties have strict requirements for high temperature and short days, while most varieties have lax requirements for sunshine. Born in areas below 2000 meters above sea level.

Fertilization methods of Auricularia auricula

The growth of Auricularia auricula needs a large amount of fertilizer and water, so the fertilizer and water management of Auricularia auricula should run through the whole daily management work. On the basis of sufficient base fertilizer, quick-acting nitrogen fertilizer should be applied many times during the growth period, and there should be no shortage of fertilizer in the whole process of Auricularia auricula cultivation, otherwise the shoot is old, the leaf is small and the quality is poor. Topdressing is usually carried out after each harvest. The amount of topdressing each time is 30% of fully mature, 50% of mature organic fertilizer, 800-1000kg per 667m2, plus urea 15kg.

Auricularia auricula likes to be wet, after each picking should be combined with topdressing irrigation, in order to keep the soil often moist, in case of drought, the number of irrigation should be increased.

Harvest of Auricularia auricula

The best time to harvest Auricularia auricula vegetables

In general, Auricularia auricula harvesting seedlings can be harvested about 40 days after sowing, when the seedlings grow to 5-6 leaves.

For the purpose of eating the tender leaves of Auricularia auricula, it was harvested once every 15-20 days in the early stage, once every 10-20 days in the middle growth stage, and once every 10-17 days in the later stage. When harvesting the tender tip of Auricularia auricula, you can cut it with a knife or scissors. Cut when the tip length is 10-15cm, once every 7-10 days. It can also be used to cut tender shoots and pick tender leaves in the early and later stages.

II. Harvesting methods of Auricularia auricula vegetables

The leaves and tender shoots of Auricularia auricula are edible. When harvested mainly by eating tender shoots, after the seedling height of 30 cm, leave 3 leaves to pinch off the head shoots, select robust lateral buds to grow new shoots, the rest are erased, and then choose 2 strong sides or new shoots after harvest. The growth potential is weakened in the later stage, and 1 or 2 strong buds or shoots can be retained after pruning to keep the leaves big and strong.

When harvesting tender leaves, leave the main vine and a side vine at the base, pick the heart when the plant reaches the top of the frame, select strong buds or new main vines from the base of the main vine, and cut off the leaves of the original main vine near the new main vine. It was harvested once in 10 days in the early stage and once in 5-7 days in the later period, with an output of 1000kg to 2000kg per 666.7 square meters.

The cultivation of Auricularia auricula is the same as other vegetables, each planting procedure is very important, in addition, Auricularia auricula has some unique growth habits and requirements, but also the cultivation of Auricularia auricula needs special attention. Now that you have decided to plant Auricularia auricula, enjoy the process!
