Detailed Guide to Saposhnikovia Seed Selection Techniques and Seedling Cultivation Methods
Saposhnikovia is a traditional Chinese medicine, also known as Huiyun, Huicao, Baizhong, etc. It has the effects of dispelling wind and releasing the exterior, overcoming dampness and relieving pain, and stopping spasms. Some farmers specifically grow Saposhnikovia to make money, so how should Saposhnikovia seeds be selected? What are the seedling cultivation methods? Next, let the editor tell everyone!
1. How to select Saposhnikovia seeds?
1. Quality: Choose high-quality, plump Saposhnikovia seeds.
2. Suitability: Choose Saposhnikovia varieties that have passed approval and are suitable for planting in the local area (through the county-level seed management department).
3. Packaging: Choose seeds with fine printing. Some major brands have anti-counterfeiting marks.
2. Seedling cultivation methods for Saposhnikovia seeds
1. Seedbed preparation
There are two types of raised-bed seedling cultivation: open-field direct sowing seedling cultivation and protected plastic arch shed seedling cultivation, which can be chosen according to local conditions.
(1) Open-field direct sowing bed
The length and width of the bed surface are generally determined by the terrain conditions, and should be tailored to local conditions, with the principle of being easy to manage. The bed is required to be level, with straight ridges and firmness.
(2) Medium shed: bed width 2.4 m, bed length 15-20 m. Small shed: bed width 1.2 m, bed length 15-20 m. Bed spacing 40 cm, all made into walking trenches 10-15 cm below ground level.
2. Suitable sowing time
(1) Seedling field
When using plastic arch sheds for early spring seedling cultivation, it should be 7-10 days earlier than open-field direct sowing seedling cultivation, because covering the shed has a moisturizing and warming effect. The cultivation method is mainly broadcast sowing.
(2) Open-field direct sowing
It should be carried out in early spring when the temperature reaches above 15°C, in early to mid-April, and ridge (row) sowing is preferable.
3. Seed treatment and sowing
(1) Soak the carefully selected seeds in warm water 3-5 days before cultivation. Soak in 35°C warm water for 24 hours, or in 40°C-50°C warm water for 8-12 hours, so that the seeds fully absorb water and facilitate germination. During soaking, stir while sprinkling the seeds, remove the shriveled seeds and impurities floating on the water surface, take out the full seeds that have sunk to the bottom after soaking, dry them slightly, and then cultivate.
When broadcast sowing in an arch shed seedling cultivation field, prepare the bed surface well, spray it thoroughly with water, then manually broadcast the seeds, using 2.5-3.0 kg of seed per mu. After even broadcasting, sift 2.0 cm of moist new soil over it with a bamboo sieve or iron sieve to preserve moisture, cover the seeds completely, then insert the arches and cover with film.
(2) For open-field flat-bed seedling cultivation, choose drill sowing. Manually open furrows with a hoe, with row spacing of 15-20 cm and furrow depth of 2-3 cm (slightly shallower for loam, slightly deeper for sandy soil). Use a dibbler to evenly sow the seeds in the furrows, cover with 1-1.5 cm of soil, and after it dries slightly, press it down to preserve moisture. For direct sowing in production fields, the cultivation method is basically the same as open-field seedling cultivation, but the row spacing should be increased to 25-30 cm, and the seeding rate per mu should be reduced to 1.0-1.5 kg.
Generally speaking, Chinese herbal medicines have relatively high sales in the market, and Saposhnikovia is no exception, with a price that is not low. Therefore, friends who want to engage in planting can try growing it. When selecting seeds, you need to choose better-quality ones.
