Planting technique of Herba Euphorbiae

Ampelopsis grossedentata is a perennial herb of Rosaceae, also known as Rhizoma thunbergii, melon vanilla, old cow tendon, wolf sprout, etc., tender stems and leaves are edible, not only nutritious but also have a strong anti-cancer effect. Whole grass, roots and winter buds have the effects of astringent hemostasis, anti-inflammation, antidysentery, detoxification, insecticidal, replenishing qi and strengthening the heart. Let's take a look at the planting technology of Herba Euphorbiae.

Growth habits of Crane Grass

Crane grass likes the warm and humid environment, the suitable growth temperature is 20: 30 ℃, and the soil requirements are not strict, but it is better to plant seeds or split roots in sandy loam with deep soil layer and loose and fertile soil. Spring sowing in late March in the south, mid-April or late April in the north, autumn sowing in the south from late September to early October, and north from late October to early November before ground freezing, root reproduction can be carried out in spring and autumn.

Propagation technique of Crane Grass

1. Sowing and reproduction: the sowing and reproduction of crane grass can be sowed in spring or autumn, in the middle and late ten days of April in the north, and before freezing in late October. When sowing, open a sowing ditch of 1 cm to 2 cm according to the row spacing of 30 cm to 35 cm. When sowing in autumn, sow the seeds evenly in the ditch, cover with thin soil, put a little pressure, and water them in time after sowing. The seed consumption is 1-1.5 kg per mu.

2. Ramet propagation: ramet propagation can be carried out in both spring and autumn, and the roots can be dug out and split. Each root must be planted with 2-3 root buds, planted in time, planted according to the hole spacing of 30-15 cm, dig a hole 15 cm deep, plant 1 root in each hole, and compacted with soil cover 5 cm. If it has sprouted, the bud will be exposed to the soil surface and watered after planting.

Planting technique of Herba Euphorbiae

1. Land selection and preparation: it is not suitable to select low-lying land and poorly drained plots for the cultivation of crane grass. Apply stable manure or compost 2000kg to 3000kg per mu as base fertilizer, apply evenly and plough. Make a flat or high bed about 1 to 3 meters wide.

2. Reasonable inter-seedling: when the seedling is 3-5 cm high, start the seedling, replenish the seedling, pull out the over-dense seedling, weak seedling, when the seedling is 15 cm high. 1 and 2 seedlings were fixed according to the plant distance of about 15 cm. If the root bud is used as medicine, the plant spacing can be appropriately increased to 30 cm, which is conducive to root development and increase the yield of root bud.

3. Intermediate ploughing and weeding: timely pulling grass and loosening soil at seedling stage is the key to ensure high yield. it is not necessary to loosen the soil after ridge sealing in the later growth stage, but it is necessary to pull grass.

4. timely topdressing: Crane grass was fertilized once before fixing seedlings and sealing ridges, and then topdressing again in early spring and after each harvest, and more nitrogen fertilizer could be applied with whole herbal medicine. Every year, 1000-1500 kg of manure or 10-15 kg of ammonium sulfate are applied per mu, and then the soil is cultivated. In order to promote the growth of roots and buds, the appropriate application of phosphorus and potassium fertilizer was applied, and calcium superphosphate was applied at 25,30kg per mu in early spring.

5. Removing the flower bolts: Crane grass blossoms and bears more fruit. Except for the remaining plants, the flowers should be removed in time to promote root growth.

6. disease control: the main pest of Xianghe grass is red spider, which sucks stems and leaves, resulting in leaf withering, shedding and plant death. insecticides such as propargite and paraben can be used to control.

7. Seed retention technique: Crane grass usually blossoms from May to July, and when the seeds turn green, brown and slightly dry in mid-late August, cut them off to dry, lay down the seeds, and store the seeds in a ventilated and dry place.
