How to plant the latest seeds of Artemisia angustifolia?

Money grass, also known as falling money, Qian Qianjin, even money grass and so on, is a perennial herb of Primulaceae, widely distributed in the tropics and subtropics of both hemispheres, and is wild or artificially planted in various places south of the Yangtze River in our country. the whole grass is beneficial to dampness and yellowing, diuresis, detoxification and detumescence. Let's take a look at how to plant the seeds.

Growth habit

Artemisia angustifolia is often born on hillside grasslands, roadsides or ditches. It likes moisture, warmth, high temperature and low temperature. It grows well in the temperature range of 16-24 ℃, and the overwintering temperature should not be lower than 5 ℃. When the room temperature is more than 30 ℃, the plant growth will be inhibited. It has strong adaptability to pH of water body, but it is best to control it between 6.5 and 7.5.

Seed sowing

The seedling raising method of Artemisia angustifolia is the same as that of ordinary vegetables. The seeds are soaked in warm water of 40 degrees Celsius for 24 hours before sowing. After being removed and dried, they can be sowed on the seedbed. After sowing, the seeds are covered with 1 cm thick sifted fine soil. Generally, the seeds begin to germinate after 7 days. When the seedling grows to 15 meters, it can be transplanted. However, because the seeds of Artemisia angustifolia are very small, it is not easy to collect, and the seedlings grow slowly, so cutting propagation is often used.

Planting management

1. Land selection and preparation: it is appropriate to choose fertile sandy loam and cool and moist land for planting. Before land preparation, apply rotten organic fertilizer 5000kg to 6000jin. After ploughing, rake the soil fine, open the box according to 1.2 meters to make a bed, the width of the box is 90 cm, the width of the ditch is 30 cm, and the depth of the ditch is 20 cm.

2. Fertilization management: 500 kg of dilute dung water per mu 20 days after planting, and 1% urea can also be applied. When the stem and vine grow to 12-15 cm, topdressing is carried out once, and 50 piculs of manure and urine are applied per mu. If there are missing seedlings in the planting hole, longer cuttings should be cut to supplement the seedlings.

3. Intermediate ploughing and weeding: before the second fertilizer application in the first year, it should be combined with ploughing and weeding once, if the weeds can be pulled out manually, and ploughing, loosening soil and weeding should be carried out after the beginning of spring in the second year, and then ploughing and loosening soil and weeding should be done once a year.

4. pest control: it is vulnerable to clam Yu and snails in the process of growth. 1000 times liquid of 90% crystal trichlorfon can be irrigated or sprinkled with 8% trichlorfon granules or 10% polyacetaldehyde granules, which can kill adults or young snails in sunny evenings.

5. Harvest and processing: money grass can be harvested when it grows to 40 to 50 meters long, and it is the finished product after drying. The finished product requires green, no impurities and no mildew. If the finished product can not be sold immediately, it can be stored in a cool and dry place and covered with nylon adhesive tape.
