Potted technique of fungus
Auricularia is a year-round vine plant of the family Amaranthaceae. Its leaves are thick, elastic, taste good, slippery and delicious, resembling fungus, hence the name of the fungus. The roots of the fungus are not developed, so the requirements for the soil are not too much. The cultivation of the fungus in the pot has become an attempt by more and more flower friends. The cultivation techniques of the fungus are now introduced as follows:
First, cultivation methods
1. Live cultivation. Pots of 20 cm in diameter, three to four seeds per pot to ensure the emergence rate. In order to facilitate emergence, it can be soaked for 1 to 2 days before seed sowing, and germinated at a temperature of about 30 °C. When the seedlings have three or four true leaves, you can choose to thin the seedlings, leaving one seedling in each pot. The seedling height can be harvested by 10 to 15 cm.
2. Seedling transplanting. Seeds are dried and seeded at a suitable temperature of 28 ° C for 3 to 5 days. If the ground temperature is low, the seeds should be germinated. If it is not a live broadcast, but choose a seedling, 4 to 5 pieces of true leaves can be transplanted and planted.
Second, choose the variety
It is advisable to use high-quality, high-yield, disease-resistant red stalked stalks, green stalks, and other edible fungus varieties.
Third, management
1. Due to management needs.
1 Take the young shoots, and leave 3 to 4 leaves at the base when the height of the seedlings is 30-35 cm. Harvest the tender heads and leave two strong side shoots. When harvesting two shoots, leave 2 to 4 lateral buds as tips. During the vigorous growth period, each plant has 5-8 strong lateral buds to shoot into the shoots. In the middle and late stages, the young shoots should be wiped out in time, and the growth is weak in the later stage. ~ 2 strong side shoots to facilitate leaf hypertrophy.
2 For the purpose of feeding leaves, it is necessary to frame cultivation. When the height of the seedling is about 30 cm, the truss frame is used to put the vines on the shelves. In addition to the main vines, two strong side vines are left at the base to form the backbone vines. Pick up the heart when you reach the top of the rack. After picking the heart, leave a strong side bud from each bone. The backbone vines are cut off after the leaves are harvested. When you are on the shelf and after each harvest, you must cultivate the soil, or you can harvest the young shoots without pruning.
2. Fertilize and water. The base fertilizer is better with organic fertilizer. Top dressing is applied by chemical fertilizer or organic fertilizer dissolved in water. After emergence, keep the soil moist and water it at the right time. After each harvest, the organic fertilizer should be applied in time, and the rainy season should be drained in time.
3. Control pests and diseases.
1 The disease that often occurs in auricula is brown spot disease. In the initial stage, it can spray 72% kelu wettable powder 500-600 times liquid, or 68.75% easy to maintain dispersible granule 800-1000 times liquid.
2 If Spodoptera litura occurs, it is found that many young leaves have small eyes, and the pyrethroid insecticide can be sprayed once at the age of 1 to 2 years.
Fourth, scientific harvesting
When there are 4 to 5 true leaves in the live broadcast, the seedlings can be pulled out one after another. For the young shoots, when the seedling height is 30-35 cm, the two leaves of the base are cut with scissors, and the germinated side branches are 5 to 6 true leaves, and then harvested according to the method. The first half of the harvest is mainly harvested from 15 to 20 days, the middle growth period is 10 to 15 days, and the later stage is harvested 7 to 10 days. The harvested leaves should be fully unfolded and not yet aged, and the leaves are thick. Only scientific harvesting can make more space grow a lot of fungus.
