The latest course of field management techniques and methods of Auricularia auricula

Auricularia auricula vegetable is one of the main vegetables with high temperature in summer in southern China. It tastes fragrant, crisp and refreshing, like Auricularia auricula, and has a unique taste. Do you know how agaric food is managed when it is planted? Let's learn about the field management skills of Auricularia auricula vegetables together with the editor.

1. The seedlings are fixed

Under suitable temperature and humidity, seedlings can emerge soon after sowing. When the seedlings grow into 1-2 true leaves, they should be interspersed once, and when they grow to 4-5 true leaves, the seedlings will be fixed. The plant distance of the fixed seedling should be carried out according to the sowing method, the plant distance of strip sowing should be controlled at about 20 cm, and the controlled plant distance for sowing should be between 8 and 10 cm.

2. Temperature management

The temperature requirements are different in different growth stages of Auricularia auricula. After the seedlings are unearthed, the temperature should be kept at 25-26 degrees during the day, 16-17 degrees at night, 28-30 degrees during the day and 18-20 degrees at night after the cotyledons are unfolded. The temperature should be lowered a week before it is taken, keeping it at 24-25 degrees during the day and 14-15 degrees at night. The purpose of cooling is to make it grow strong, increase leaf thickness and color, and improve yield and quality.

3. Soil, fertilizer and water management

Generally speaking, after slow seedling, shelf or harvest, intermediate ploughing and weeding should be carried out, and soil should be properly cultivated at the same time to avoid root system exposure. on the basis of sufficient basic fertilizer, quick-acting nitrogen fertilizer should be applied many times during the growing period, generally 15 kg of urea per mu and 5-8 kg of phosphorus and potassium compound fertilizer per mu. After each harvest, fertilizer should be applied in time, with 15 kilograms of urea per mu each time. Auricularia auricula vegetables like a humid environment, so often watering, keep the soil moist, but each time the amount of water should not be too much, should be watered frequently.

4. Plant adjustment

When harvesting, young shoots are mainly harvested. When the seedlings are 30 cm high, 3-4 leaves are left to collect tender shoots, 2-3 strong lateral buds are left, and all other buds are erased; in the second harvest, 2-4 strong lateral buds are left and the rest are erased; 5-8 strong lateral buds can be selected in the growing season, and flower buds should be wiped out in time in the middle and later stages to reduce nutrient consumption. At the end of harvest, the weakening of plant growth is that 1-2 strong lateral buds are selected, which is beneficial to the hypertrophy of leaves, fat shoots, strong stems, good quality and high yield.
