The latest course of planting techniques and methods of sage

Sage Labiatae Sage is a small evergreen subshrub, with woody stems, gray-green leaves, blue to blue-purple flowers, native to southern Europe and the Mediterranean coast, has many different uses and effects, often cultivated as a kitchen herb or medical herb, with high cultivation value, let's take a look at sage planting technology!

Growth Habits of Salvia officinalis

Sage likes sunny or semi-shady environment, cold tolerance, can withstand-15℃ low temperature, like good drainage sandy loam, more fertile, drought resistance is strong, like good drainage slightly alkaline calcareous soil, born on hillside, roadside, shaded grass, water and shade, China mainly grows in Zhejiang, southern Anhui, Jiangsu, Jiangxi, Hubei, Fujian, Taiwan, Guangdong, Guangxi and other places, Japan also has distribution.

Breeding technique of Salvia miltiorrhiza

1, seed propagation: sage can be sown in spring and early autumn, before sowing in order to improve the emergence rate and early emergence, can first soak the seeds with warm water at 50℃, when the temperature drops to 30℃, wash with water several times, put in 25~30℃ constant temperature germination or with water soaked for 24 hours after sowing. Direct seeding or seedling transplantation can be. Because sage seeds are small, they should be sown shallow. Cover with thin soil after sowing and sprinkle frequently to keep the soil moist.

2, cuttage propagation: sage cuttage propagation usually in 5~6 months to select the top of the branch is not too tender, 5~8 cm long, in the stem node lower cut, pick the base 2~3 leaves, according to the row spacing of 5 cm ×5 cm, inserted into the seedbed, 2.5~3 cm deep. After planting, water and cover plastic film to keep moisture. After 20~30 days, plant new roots according to the density of (45~50) cm × (25~30) cm.

Sage planting techniques

1. Transplanting into the upper pot: When the true leaves of Salvia miltiorrhiza reach 2 to 3 pieces, transplant into the upper pot. Generally, select a nutrient pot of 12 cm to 13 cm for transplanting. Select loose and ventilated garden soil with organic fertilizer and compound fertilizer as substrate. When 4 pairs of true leaves were grown, 2 pairs of true leaves were reserved for pruning to promote lateral branches.

2. Temperature management: After sage is placed in the basin, the temperature is reduced to 18℃, and it can be reduced to 15℃ after one month. If the temperature is below 15 ° C, the leaves will yellow or fall off, and when the temperature is above 30 ° C, there will be small flowers and plants to stop growing.

3. Fertilization management: ammonium sulfate diluted 1500 times during the growth period of Salvia miltiorrhiza is applied to change the leaf color, and the effect is better. Urea should not be applied at low temperature. In order to make the plant roots strong and branches and leaves luxuriant, it is very important to apply fertilizer continuously. Compound fertilizer containing calcium and magnesium is applied once a half month, and phosphorus and potassium fertilizer are applied once before flowering.

4, light management: sage likes sunny environment, hot summer needs appropriate shade, seedling stage to strengthen the light to prevent excessive growth.

5. Disease and pest control: Common pests of sage include whitefly, aphid, etc., which need to be actively controlled. Common diseases are downy mildew, leaf spot disease, etc. When the disease occurs, 50% thiophane wettable powder 500 times solution can be sprayed for control.
