The latest culture methods and matters needing attention of sage

1. Cultivation: Sandy loam or deep loam with adequate sunshine and good ventilation and good drainage is better, which is beneficial to growth. Seed direct seeding, 3-5 seeds per hole, one week after germination or when the plant is as high as 5-10cm, seedlings should be thinned. Spacing 20-30cm. After the adult plant can be thinned again, increase the distance, the growth is more exuberant. Different varieties of sage need different light intensity, which needs to be confirmed and understood before cultivation.

2. Methods of reproduction

① seed propagation

Seeds can be sown in spring and early autumn. Before sowing, in order to improve the seedling emergence rate and early emergence, the seeds can be soaked in 50 ℃ warm water. When the temperature drops to 30 ℃, rinse with clean water several times, and then germinate at 25: 30 ℃ or soak in water for 24 hours before sowing. Direct seeding or seedling transplanting can be done. As the seeds of sage are small, they should be sown shallowly. Cover thin soil after sowing and sprinkle water frequently to keep the soil moist.

② cuttage propagation

From May to June, the tip, which is not very tender at the top of the branch, is 5 cm long and 8 cm long, cut off at the lower position of the stem node, remove the basal 2-3 leaves, press the row spacing 5 cm × 5 cm, and insert it into the seedbed with a depth of 2.5 cm. After planting and watering, and covered with plastic film to moisturize, the new roots were sent out after 20-30 days, and then planted according to the density of (45-50) cm × (25-30) cm.

3. Field management

After planting, the soil should be loosened and weeded in time, irrigated properly in case of drought, and drained in time after rain. In the growing season, topdressing 2 to 3 times according to the situation, each time can recover about 5 kg of urea per mu. To the north of the Yangtze River, soil needs to be cultivated in winter to survive the winter. generally, 20 cm-high soil is cultivated after the above ground is harvested and irrigated before freezing in winter, and the soil is opened and watered at the end of the next spring to make the buds grow. South China can survive the winter safely without coverage.
