How to grow Salvia chinensis? The latest planting techniques and method tutorial
Salvia chinensis, also known as Zishen, has whole plants that can be used as medicine, with effects of promoting blood circulation and removing blood stasis, clearing heat and detoxifying, and reducing swelling and relieving pain. It is a relatively common plant in rural areas. According to modern research, it can also inhibit the growth of tumor cells, and demand has surged. So how should Salvia chinensis be grown? Let's take a look together.
1. Site selection and land preparation
Salvia chinensis prefers a warm or cool climate and often grows on hillsides, roadsides and in field grass. In the north, it is generally cultivated in the warm season. Choose a plot with higher terrain, deep soil, loose and fertile soil texture, and good drainage for planting. After selecting the site, clear the weeds and remaining plant residues from the plot, then plow the soil 20-30 cm deep, let it weather naturally, then apply base fertilizer, and make beds or ridges ready for planting.
2. Propagation methods
In production, seed propagation is generally used. When the seeds mature, harvest them, remove impurities, and store them for later use. In spring, sowing begins in March-April. First open a shallow furrow on the bed surface at a row spacing of 30-35 cm, sow the seeds evenly into the furrow, then cover with about 1 cm of soil. It should not be too deep, so as to avoid difficulty in seedling emergence. After sowing, water thoroughly once and cover with a layer of rice straw to keep warm and moist, which helps seedling emergence. In this way, seedlings can emerge after about half a month.
3. Field management
After the seedlings emerge completely, thin them in time. While thinning, pay attention to weeding and loosening the soil. Weed frequently; manual weeding is recommended, so that there are no weeds in the field. When loosening the soil, be careful not to go too deep, so as not to damage the root system and affect the normal growth of the seedlings. In order to speed up the growth of the seedlings, apply 1-2 times of dilute fertilizer water appropriately during the seedling stage. In drought, water in time to keep the soil moist, which is beneficial to seedling growth. In the rainy season, drain in time to prevent waterlogging, so as to avoid root rot and death of the seedlings.
4. Harvesting
Salvia chinensis is originally a wild plant with strong environmental adaptability, so there are rarely pests and diseases during cultivation. When pests and diseases occur, conventional methods can be used for control. When Salvia chinensis blooms, except for plots kept for seed production, the remaining plots can be harvested. Cut the whole plant, and use it fresh or dry it in the sun.
