How to cultivate grass coral: like shady and cool environment, avoid strong light and high temperatu

Grass coral, with its beautiful shape and four-year fragrance, has high medicinal, edible and ornamental value. It has the effects of dispelling wind and removing dampness, promoting blood circulation and relieving pain, and connecting the meridians and bones, so more and more people choose to plant grass coral artificially. So how to plant grass coral? Let's read on!

How to cultivate grass coral

It should be planted in the hillside field, row field or sandy soil area beside the gully and stream and under the shade of the forest in the valley where the water source is convenient. In autumn and winter, the soil was dug and naturally weathered, and the soil was prepared before planting in the next spring. It is better to choose the plot under the evergreen broad-leaved forest with damp, deep soil layer and loose texture. During land preparation, 2000 kg of farm soil and miscellaneous fertilizer were applied per mu, ploughed into the soil, raked and leveled to form a high border with a width of 1 meter.

2、 Methods of reproduction

Cutting propagation, seed and ramet propagation are often used in production.

1. Cutting propagation: from March to April, select 1-2 years old branches from robust plants, cut them into cuttings with 2-3 nodes and 10-15 cm long, bundle them into small bundles, and soak the base end in 0.05 ml / L 3 ABT rooting powder solution for 2-3 minutes, or quickly dip them in 1 ml / L NAA solution for cutting. The rooting time of treated cuttings was significantly shortened, and the survival rate was almost 100%. After cuttings treatment, on the seedbed prepared in advance, insert soil obliquely according to the spacing of 5 cm x 0 cm, leave one node on the soil surface, press tightly, and pour water. If the seedbed is small, it is best to set up a shade and keep the seedbed moist. About 30 days after cutting, the cutting took root and began to sprout. After survival, we should pay attention to loosening the soil and weeding, and timely apply the thin water of human and animal manure to promote the growth of seedlings. After 10-12 months of cultivation, it can be planted out of the nursery.

2. Seed propagation: from October to December, when the fruit is red and ripe, collect it, mix it with fine wet sand (seed: wet sand = 1:2, store it in a high dry and ventilated place indoors, or put it in a wooden box, store it in a ventilated place indoors, and take out the seeds for sowing in February to march of the next spring. On the seedbed, open a 2-3cm deep furrow with a row spacing of 20cm, and evenly sow the seeds in the furrow. Cover the furrow with flint ash or fine soil. Cover the furrow with grass and set up a shade. The seedlings emerged about 20 days after sowing, and the grass cover was removed in time. During the seedling period, we should often loosen the soil and weed, timely topdressing. If the management of seedling stage is fine, it can be planted in the nursery from November to December of that year.

3. Ramet propagation: in early spring or late autumn. First, cut the aboveground part of the plant 10 cm above the ground for medicine or as cutting material, then dig up the root stump, divide it into small plants with roots according to the stem, and plant directly in the field according to the row spacing of 20 cm × 30 cm. After planting, continuous watering is needed to keep the soil moist. Pay attention to weeding and fertilization after survival. This method is simple, with high survival rate, fast plant growth and low reproductive coefficient.

4. Transplanting: seeds and cuttings of seedlings, generally in November and December of that year or the next spring February to March transplanting. On the finished border, plant according to the spacing of 20 cm × 30 cm, and irrigate the fixed root water thoroughly. After survival, the field management should be strengthened in time.

3、 Field management

1. Check seedlings and replenish seedlings: check seedlings in time after transplanting. If dead seedlings and lack of plants are found, soil should be taken to replenish seedlings to ensure the whole seedlings.

2. Weeding in the field: weed in the field should be removed in time at seedling stage, and soil loosening in the field should be carried out properly. In general, the soil should be ploughed 3-4 times a year to keep the soil loose and free from weeds.

3. Irrigation and drainage: keep the soil moist after planting, and irrigate in time in case of drought. Rainy season, such as the field water, to remove in time, so as not to cause rotten roots.

4. Topdressing: generally, topdressing is applied once a year in spring and summer, with 6-7kg ammonium nitrate or urea and 2-3kg potassium chloride applied per mu for water irrigation. In winter, combining with soil cultivation, applying farmyard manure once, applying fence manure or compost to the rhizosphere of plants, lifting the soil beside the ditch to cover fertilizer can not only keep warm and prevent cold, but also promote the early growth and rapid growth of plants in the next spring.

5. Field: Intercropping Corn and other high stalk crops, using high stalk crops to shade properly. Through the management of intercropping crops, not only the growth of Sarcandra glabra can be promoted, but also the economic income can be increased.

4、 Pest control

Sarcandra glabra has just been transformed from wild to domestic, and it has strong resistance to diseases and insects. At present, no serious diseases and insect pests have been found, so there is no need to control them. However, if the shading conditions in the field are poor and the sunlight is strong in summer, the leaves will be burned, the leaf tips or leaves will be withered, and the whole leaves will be seriously withered. In order to reduce the damage, measures such as irrigation to reduce the temperature and improve the shading conditions can be adopted.
