When will Salvia miltiorrhiza be planted

If Salvia miltiorrhiza is planted in North China, the more suitable planting time is from mid-late March to early April, while if it is planted in the Yellow River basin, the more suitable planting time is about July-September. If cutting planting is needed, it is generally carried out from June to July in the north and from April to May in the south, and the branches with strong growth are selected for cutting planting.

1. Sowing time of Salvia miltiorrhiza seed

Planting Salvia miltiorrhiza in North China can be planted from mid-late March to early April in the Gregorian calendar, and in the Yellow River basin in June-August of the lunar calendar. Rain Water is relatively abundant in this season, and the corn seedlings grown are also covered with the ground, and the seeds of Salvia miltiorrhiza are sown in the corn field. the survival rate is relatively high.

2. Propagation time of Radix Salviae Miltiorrhizae

1. When harvesting in autumn, the root of Salvia miltiorrhiza, which is 0.7-1cm in diameter, purplish red in color, pest-free and well-developed, can be selected as seed root and stored in wet sand. From March to April next year, the seed root will be cut into small segments of 4-6cm. According to the specification of row spacing as 35cm, plant spacing as 25cm and depth as 6cm, the cut seed root will be put vertically into the dug hole.

2, each hole put a small section of seed root head up, and then cover the soil around 2cm, the cover soil should not be too thick, otherwise it will affect seedling emergence, the average per mu can use about 100jin of seed root, select Salvia miltiorrhiza root section planting, flowering will be relatively late, it is difficult to harvest seeds in the planting year, but the root growth will be relatively fast, and the yield of medicinal materials will be very high.

3. Cutting and planting time of Salvia miltiorrhiza

1. From June to July in the north and from April to May in the south, the branches of Salvia miltiorrhiza which are robust and disease-free are cut into long segments of 13-16cm. The tail incision should be close to the stem node, showing the shape of a horseshoe, and the tail leaves are cut off. According to the specification of row spacing for 20cm and plant spacing for 10cm, the cuttings are obliquely inserted into the seedbed.

2. The depth of the cuttings is 1-2-3, and then the covering soil is gently pressed, and 1-2 leaves are retained on the ground, which can be cut while cutting, and the cuttings should not be placed for a long time, otherwise, the survival rate of cuttings will be affected. Watering should be carried out after cuttings to keep the soil moist, and appropriate shading should be carried out during the period. Generally, after 15-20 days, new roots will be produced from the stem nodes at the bottom, and when the roots grow to 3cm. And then transplant it to Daejeon.

Fourth, the cost of planting one mu of Salvia miltiorrhiza (excluding land contract fees)

1. Seedling cost: 8000 seedlings of Salvia miltiorrhiza are planted per mu, the price of high-quality seedlings on the market is 0.06yuan, and the cost of seedlings per mu is 480yuan.

2. The cost of cultivated land: deep ploughing once before planting, rotary ploughing once, the cost per mu is about 80 yuan.

3. The cost of fertilizer and pesticide: using 100 jin compound fertilizer as base fertilizer per mu, the cost is about 150 yuan, and the cost of topdressing is about 50 yuan, totaling about 200 yuan. Salvia miltiorrhiza has relatively few diseases and insect pests. During the growth period, prevention is mainly focused on, so the cost is negligible.

4. Other costs: the labor costs of planting, receiving and drying, as well as planting methods, planting time, environmental conditions and other different reasons, no budgeted expenses, an average of 800 yuan.

Profit from planting one mu of Salvia miltiorrhiza

When Salvia miltiorrhiza is planted in late autumn or early spring, the growing period is one year, and the harvest is carried out in the autumn of that year. If there are no natural disasters in that year, each plant can produce 50g dry goods on average. Take 8000 trees per mu as an example, calculated according to the survival rate of 90%, about 720jin of dry Salvia miltiorrhiza can be harvested per mu of land. According to the current market price of 28-36 yuan per kilogram, the income per mu is about 6000-6500 yuan, excluding planting costs. The net profit of one mu of land is about 3300-4800 yuan.
