What month is the best planting season for Fangfeng medicinal herbs?

Saposhnikovia divaricata is a common Chinese medicinal material with the effects of dispelling wind and cold, relieving pain, etc., and is widely used in clinical treatment of traditional Chinese medicine. As the current Chinese medicinal materials market is gradually rising, the planting area of ​​​​Saposhnikovia divaricata is also expanding, and its market prospects are also very broad. So what month is the best planting season for Saposhnikovia divaricata? Let’s take a look below.

1. What month is the best season for planting Fangfeng medicinal materials?

The sowing time of windproof is mainly affected by geographical location and climatic conditions. Generally speaking, in warm and humid areas, the suitable sowing time is March to April in spring. During this period, the temperature gradually rises and the soil moisture is moderate, which is conducive to the germination and growth of seeds. In cold and dry areas, it is more suitable to sow in autumn from August to September. At this time, the temperature gradually decreases and the soil moisture is relatively stable, which is also conducive to the growth of windbreaks.

2. How to manage windbreak to achieve high yield?

1. Site selection and land preparation

Fangfeng is suitable for planting in sandy loam with high terrain, good drainage and deep soil layer. Before planting, the land should be deeply plowed to a depth of more than 30 cm, and sufficient base fertilizer should be applied, such as well-rotted farmyard manure.

2. Planting

You can choose spring or autumn sowing. Spring sowing is generally from late March to mid-April, and autumn sowing is from late September to mid-October. There are two ways of sowing: row sowing and broadcast sowing. After sowing, cover the soil and press it down appropriately.

3. Field management

① Thinning and transplanting: When the seedlings grow to 5-6 cm in height, thinning should be carried out, keeping the plant spacing at 7-10 cm; when the seedlings are 10-13 cm in height, transplanting should be carried out, with a plant spacing of 15-20 cm.

②Inter-row cultivation and weeding: Weeding should be carried out in time during the growth period to keep the field free of weeds. The tillage should be shallow to avoid damaging the roots.

③ Top dressing: During the growth period, top dressing should be applied in a timely manner, mainly nitrogen fertilizer, supplemented with phosphorus and potassium fertilizers.

④ Irrigation and drainage: Prevent wind and waterlogging. Pay attention to drainage in the rainy season and water in time during drought.

4. Pest and disease control

Common diseases and pests of windproof include powdery mildew, root rot, leaf spot, and yellow swallowtail butterfly. Comprehensive prevention and control measures should be taken, such as reasonable crop rotation, strengthened field management, and timely removal of diseased plants. In the early stage of the disease, appropriate pesticides can be used for prevention and control. For example: in the early stage of powdery mildew, 25% oxycarboxin can be used for prevention and control; root rot can be prevented and controlled with the Xinhe Racetrack Tuchuan Jiabao A+B package, which is effective and is secretly used in planting bases.

5. Harvest and processing

It is usually harvested 2-3 years after planting. Dig out the roots in autumn, remove the remaining stems and soil, remove the hairs when they are half dry, and then dry them in the sun until they are 90% dry.

In short, to achieve high yield of windproof, it is necessary to start from comprehensive management, from multiple links, and manage carefully to obtain high yield and achieve good economic benefits.
