Experience of high yield cultivation of Ligusticum chuanxiong

1. Land selection and preparation

Early rice fields are selected for planting in Sichuan producing areas. after harvesting early rice, they are ploughed and turned into beds and raked flat.

two。 Cultivate seed material

The aboveground stem nodes of Ligusticum chuanxiong, commonly known as "Lingzi", were specially cultivated in mountainous areas with elevations of 900-1500 meters above sea level for planting in flat or hilly areas. The stem nodes of Ligusticum chuanxiong were planted at a distance of 20 cm × 20 cm before the beginning of spring. Seedlings emerged in early March and harvested in mid-July when the stem node disk was enlarged and the stem was red. Cut off the rhizome, called "Ligusticum chuanxiong", can be used medicinally, and then bind the stalk into small bundles and store it in a cool cave as breeding material.

3. Planting

Before and after the beginning of autumn, no later than the end of August. Trench in the whole ground, row spacing 30 cm, depth 3 cm, plant spacing 20 cm, put Lingzi obliquely into the ditch, bud head up, planting should not be too deep or shallow, exposed half on the soil surface. After planting, cover a layer of straw on the border to avoid direct sunlight, using Lingzi about 40 kilograms per mu.

4. Field management

By late August, all the planted moss seeds will emerge, which should be ploughed and weeded for 3 times in time, combined with topdressing, human manure and chemical fertilizer can be used to ensure the exuberant growth of Ligusticum chuanxiong. In the period of vigorous growth, root rot often occurs, so it should be drained in time, and the diseased and dead plants should be pulled out, so it is difficult to prevent and cure the disease. The diseases on stems and leaves are powdery mildew and leaf blight. Powdery mildew can be sprayed with chlorhexidine, and leaf blight can be controlled by Dysen zinc.
