Planting Ligusticum chuanxiong is generally applied with farm fertilizer, nitrogen fertilizer and compound fertilizer. Ligusticum chuanxiong is a fertilizer loving crop, but its root system is short, so it is necessary to choose thinner fertilizer when applying fertilizer. When deep ploughing the land, some thinner human and animal manure water can be applied as base fertilizer. In the seedling growth stage, a small amount of nitrogen fertilizer and diluted farm fertilizer can be added to promote the growth of their roots. When flowering and fruiting, plant ash compost can be applied to promote rhizome expansion. 1、 What fertilizer should be applied to Ligusticum chuanxiong? Rotten farmyard fertilizer should be used as base fertilizer for planting Ligusticum chuanxiong. Applying 3000-4000 kg of diluted human and animal manure water per mu can effectively improve the soil structure and provide nutrients for their growth and development.
When the seedlings grow to about 10cm, fertilizer can be applied once in combination with weeding. After mixing and diluting the farm manure and purified water in the ratio of 1:1, water it around the plant. After that, fertilize every 30 days in combination with weeding, and it is recommended to use compound fertilizer or human and animal manure water.
In the flowering stage, plant ash and vegetable oil cake can be composted, ditched and cultivated. Increase the number of flower buds, prolong the flowering period and increase the yield. In addition, according to the leaf growth status, you can add a leaf fertilizer and spray it directly on the plant. 2、 Scientific management of planting Ligusticum chuanxiong 1 Check and supplement seedlings: when the seedlings grow to about 7cm, check and supplement seedlings. Make up seedlings in vacant places and divide seedlings in dense places.
2. Prevention of diseases and insect pests: cooperate with weeding and spraying pesticides during the first fertilization. Spray chlormequat fungicide and other pesticides according to the instructions.
3. Picking foot leaves: before the third fertilization, dig up the soil near the plant, and then cut off the old yellow foot leaves. Each plant should leave 3-4 main stems to facilitate rhizome expansion and form a relatively strong Chuanxiong Lingzi. （ChuanXiongShiShenMeFei）
