North Sanqi grass planting technology

Sanqi Cao is a plant of the Asteraceae family, also known as chrysanthemum notoginseng, blood peony, etc. It has the effects of promoting blood circulation, swelling, detoxification, and removing phlegm. It is mainly produced in Yunnan-Guizhou and Guangdong-Guangzhou regions. The northern introduction and cultivation techniques are introduced as follows.

1. Biological characteristics

Hi warm and moist environment, loose, fertile sandy loam is better, the soil requirements are not strict, but the clams and clay are not suitable for cultivation. Not cold.

2. Soil preparation and fertilization

Apply 3000 to 5000kg per mu of land-fertilizer, pound fine, and spread evenly, deep plowing 20cm, fine leveling, making 1m wide to do, spare.

3. Breeding method

(1) Rootstock propagation: From March to April, choose a robust, disease-free rhizome and cut into small pieces. Each root should have 2 or 3 buds. After cutting, cut the incision or mix it with plant ash and plant it. In the entire well, the spacing of 6 to 10 cm deep is set at 35 to 40 cm, and the cut rhizome is placed in the ditch at a plant spacing of 20 to 25 cm. The tip of the bud is upward, covering the soil and flattening. About 15 days after planting emerged. During drought, water can be poured into the pot first, and then the water will be cultivated after seeping to ensure its survival rate.

(2) Cutting propagation: From June to July, during the high temperature and rainy season, choose robust, disease-free shoots, cut into 10 to 15 cm long sections, remove the lower leaves, keep 2 to 4 leaves at the top, and insert them diagonally in the sand. Leave about 5cm above the soil surface. It can survive in about 2 weeks, and can be transplanted 2 weeks after survival. The transplant spacing is the same as that of rhizome propagation.

4. Field management

Water the plant on time to prevent drought. After the seedlings are aligned, they should be cultivated and weeded on time. During the vigorous growth of plants, one-time human or animal manure water can be applied, or 20 kg urea can be applied per mu. During the rainy season, water should be prevented from accumulating in the ground and drained in time to prevent root rot.

5. Pest Control

Panax notoginseng has fewer pests and diseases, and the main pests are ground tigers and aphids. When the place where the tiger is harmed, can be used 1:100 times liquid spray control of trichlorfon original drug, or 50% phoxim 50g minced fresh grass made of 5kg poison bait; in the event of locust damage, 40% dimethoate can be used Emulsion 1000 to 1200 times spray control.

6. Harvest processing

The harvest was harvested in the middle and late October of the year. When harvesting, cut off the stems from the ground and dig out the roots. After drying to dryness, remove fibrous roots and dry them for medicinal purposes.

7. Planted storage

In the north, Sanqi grass is best stored in the cellar, and the cellar temperature is controlled at 0 to 5°C. When stored, the top buds are placed upwards, a layer of sand and rhizomes, and 4 to 5 layers are covered with sand and sand. To check regularly to prevent fever and mildew.
