What are the key points of the planting method of crisp and refreshing agaric vegetables?

I. planting time of Auricularia auricula

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 suitable 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.

II. Key points of planting methods of Auricularia auricula

1. Fertilization and soil preparation

Auricularia auricula is a kind of vegetable that is afraid of cold, so it has a good ability to adapt to high temperature, and it is generally suitable to be planted in loose sandy soil. Auricularia auricula needs enough water in its whole growth process, so we should pay attention to a good drainage and irrigation system. When carrying out land preparation, we should pay special attention to applying a sufficient amount of farm manure as basic fertilizer, and at the same time, we should turn the land deeply and plant it deeply, and then make a bed after turning the land over. Generally speaking, about one meter of the border is enough. When making the border, do a good job of the ditch used for drainage and irrigation in the field, so that it can be used directly.

2. Seed treatment

Soak the seeds before sowing, because the seed coat of Auricularia auricula is relatively hard, if you simply sow directly, it may not germinate for a long time. When soaking the seeds, you should pay attention to the water temperature and time. First, soak in the water of about 50 degrees for half an hour, then soak in the water of about 30 degrees for five or six hours, and finally fish out the seeds and put them in a place with a higher temperature to promote germination. Generally, the buds will be white after three to four days, and then the seeds can be sowed.

3. Sowing and planting

There are two ways to sow seeds. The first is to sow the seeds on the border at intervals of 40 cm between rows and 30 cm between plants. The second is to sow seeds and raise seedlings until the seedlings grow three to four leaves for transplanting. The distance between each plant and each row is also 40 cm and 30 cm.

4. Field management

After planting, if there is no rain, water should be watered every three days, and the first fertilization should be carried out after it grows new roots. if it rains after transplanting, you can take advantage of the rain to apply urea, which can promote its growth. Auricularia auricula vegetables can be harvested before they grow taller for a period of time. Fertilization should be carried out after harvest to help it grow new leaf branches quickly.

5. Disease prevention

The main diseases of Auricularia auricula are Brown spot and Botrytis cinerea, which mainly harms the leaves and causes brown spots on the leaves, which will wither the whole plant in serious cases, while Botrytis cinerea has water-stained light green spots, and the diseased stems are easy to fold and rot. We usually spray 72% Kloe wettable powder 600x liquid, or 75% chlorothalonil wettable powder 600x liquid, or 70% methyl topiramate wettable powder 1000 times every five to seven days, and basically do this two or three times in a row.
