Detailed Explanation of Glehnia Planting Techniques and Per-Mu Profit Analysis

Glehnia littoralis, also known as glehnia, is mainly produced in various northern regions and is a precious traditional Chinese medicinal variety in China. So what are the glehnia planting techniques and per-mu profit?

Glehnia per-mu profit analysis

Calculated on the basis of normal annual per-mu yield, with a per-mu yield of 300-400 kg, the net profit will reach more than 3000 yuan. At the same time, a high per-unit yield means the product is large in size and good in quality, so the selling price will naturally be higher. Therefore, after deducting the factor of yield reduction in disaster years, and calculated at current prices, farmers still gain certain benefits and enthusiasm from planting Glehnia littoralis.

Glehnia planting techniques

1. Site selection and land preparation

Glehnia is a deep-rooted plant. Choose a half-shade, half-sun slope, and it is suitable for cultivation in fertile soil, deep soil layers, well-drained, sandy, weakly acidic soil. Avoid continuous cropping, and it should not be planted in clay soil, low-lying dusty land, or saline-alkali land. The planting site should also be selected as loose, fertile sandy soil, and the terrain should be sunny.

2. Seed selection and seed treatment

Seeds free of disease should be selected to prevent the seeds from carrying pathogens, which would affect emergence and seedling growth. Choose seeds that have undergone several generations of evolution. Such seeds have strong adaptability and grow quickly, with high emergence rates and seedling survival rates, and their disease resistance and stress resistance are far higher than those of seeds that have not undergone evolution. Choose seeds that are large and plump.

3. Sowing

The sowing period for glehnia is generally after Lidong (Start of Winter) and before Xiaoxue (Minor Snow), when the land has not yet frozen, but some also sow at Spring Festival, because winter sowing produces more uniform emergence, more vigorous growth, and stronger drought resistance than spring sowing. However, winter sowing should not be too early, to avoid early emergence making the seedlings susceptible to freezing injury. Spring sowing should be around Jingzhe (Awakening of Insects), and preferably no later than Qingming. About 7.5 kg of seeds are needed per 667 sq m. Before sowing, soak the seeds in warm water at 30°C (1 part boiling water, 2 parts cold water) for 5-10 minutes, drain off the water, and leave them for 1 night before sowing. When sowing, open a furrow every 13 cm, with a furrow width of 13 cm and a depth of about 6.5 cm; if it is pure sand, it can be a little deeper. Then evenly scatter the seeds into the furrow, gently tread once with the foot, and cover with about 3 cm of soil.

4. Weeding

For weeds in glehnia fields, generally do not use a hoe to remove them but pull them by hand, so as not to damage the seedlings with the hoe and affect the growth of the roots. Pull them whenever there are weeds, at least 5 times each year.

5. Watering

In the past, glehnia was mostly grown without watering, because it was believed that watering made the roots prone to rot. One year in Laiyang, Shandong, the weather in June was especially dry, and they broke with convention and watered the glehnia field. As a result, the yield of the watered Glehnia littoralis was more than 1 times higher than that of the unwatered ones. This fully shows that under dry conditions, watering in appropriate amounts can promote better growth of glehnia.
