Technical points of daily maintenance and management of orchid sage

Orchid sage is a perennial herb, which likes warm, moist and sunny environment, has strong cold tolerance, and is afraid of heat and dryness. It is suitable to grow in loose, fertile and well-drained sandy loam soil. In daily maintenance, efforts should be made to keep the leaf surface dry and prevent diseases. The following is to introduce you the knowledge of daily maintenance and management of orchid sage.

Technical parameters of orchid sage maintenance:

The main results are as follows: 1. In order to make the plant have strong root system and luxuriant branches and leaves, continuous fertilization is very important. 100ppm, a compound fertilizer containing calcium and magnesium, is used once a month.

2. Spray 700 times carbendazim or chlorothalonil every 7-10 days.

3. Cultivation reference: about 250-300 seeds per gram, suitable for sowing and sowing in spring and summer.

4. Soil temperature of germination: 20 ℃ 23 days of germination: 5 Mel 8 days

5. Suitable temperature for growth: 18murmur23 ℃ from sowing to flowering: 70Mel 100 days

6. Ph value: 5.5, Musi 5.8, plant height: 20, 35 cm.

Daily management of orchid sage:

The orchid sage is usually sown from January to the middle of February and in the middle of July, and can be sowed at any time according to the need. The matrix is best made of peat and perlite, as well as rotten leaf soil. The culture soil was sifted and placed in a seedling plate, soaked with 500 Mel 600 times carbendazim solution, dried slightly and then sowed, about 1000 tablets per square meter.

After sowing, the covering soil is sprayed with liquid medicine to facilitate the close contact between the seeds and the substrate. Cover with film or glass to shade and keep moist. After emergence, gradually remove the film and gradually strengthen the light. Use chlorothalonil or tocopherol every week to prevent cataplexy, once every 10 days.

Hefei liquid 150PPM, add thin organic fertilizer solution to each watering. The cultivated soil quality is better in fertile loam or sandy loam with good drainage. If the soil is mixed with organic fertilizer before planting, the growth will be better.

The radicle appeared in the first stage of orchid sage germination, and the root began to form. There is no need to apply fertilizer at this stage, but it is very important to keep the seedling medium moist and need a certain amount of light. Gradually remove the film after emergence. 1000 times chlorothalonil or tocopherol was sprayed 2 to 3 times a week to prevent cataplexy.

The second stage of germination continues to take root, the stem appears, and the cotyledons have unfolded. To maintain proper humidity and prevent excessive humidity, water-soluble fertilizer with a ratio of 20-10-20 of nitrogen, phosphorus and potassium can be properly applied. In the third stage of germination, the root can be inserted into the hole of the disk, and several true leaves appear.

Increase the concentration of fertilizer, control humidity and temperature, the temperature is reduced to about 20 ℃, need some light to prevent seedlings from overgrowing at this stage. In the fourth stage of germination, the root system clumps, with 2 to 3 pairs of true leaves. Continue to increase the fertilizer concentration, temperature and humidity are the same as the third stage, properly control moisture, strengthen ventilation, still need to prevent overgrowth and prepare for transplanting.
