Planting techniques and mu income of Panax quinquefolium

Radix Glehniae, also known as Radix Scutellariae, is mainly produced in various parts of the north and is a precious variety of traditional Chinese medicine in China. So what is the planting technology and mu income of Radix Ginseng?

Analysis of income per mu of Radix Ginseng

According to the normal annual yield per mu, if the yield per mu is 300,400kg, the net income will reach more than 3000 yuan. At the same time, a high unit output means that the product is of large size and good quality, and the selling price will naturally be higher. Therefore, after deducting the factors of yield reduction in disaster years, farmers still have certain benefits and enthusiasm in planting Radix Glehniae at current prices.

Planting technique of Radix Ginseng

1. Land selection and land preparation

Sand ginseng is a deep-rooted plant, and the semi-shady and semi-sunny slope is suitable for cultivation in fertile soil, deep soil layer, good drainage and weak sandy acid soil. Avoid continuous cropping and should not be planted in clay, low-dust and saline-alkali land. The planting site should also choose loose and fertile sandy soil, and the topography should be sunny.

2. Seed selection and seed treatment

The disease-free seeds should be selected to prevent the seeds from carrying bacteria and affect the emergence and growth of seedlings. Choose seeds that have evolved over generations. This kind of seed has strong adaptability and fast growth, "seedling rate and seedling protection", disease resistance and stress resistance are much higher than those of unevolved seeds. Choose seeds that are large and full.

3. Sowing seeds

The sowing time of sand ginseng is generally from the Beginning of Winter to Lesser Snow, when the land has not yet frozen, but there are also those sown during the Spring Festival, because winter sowing is better than spring sowing in terms of seedling emergence, vigorous growth and strong drought resistance, but winter sowing should not be premature to avoid early emergence and susceptibility to freezing damage. Spring sowing should be before and after the sting, but the Qingming Festival is the best. About 7.5 kilograms of seeds are needed for every 667 square meters. Soak the seeds in warm water of 30 ℃ (1 part of boiled water and 2 parts of cold water) for 5 minutes before sowing, drain the water, and sow the seeds after 1 night. When planting, a trench is opened every 13 centimeters, with a width of 13 centimeters and a depth of about 6.5 centimeters. If it is pure sand, it can be deeper, then spread the seeds evenly in the ditch, tread gently with your feet, and then cover about 3 centimeters of soil.

4. Weeding

The weeds in the sand ginseng field are generally pulled out by hand without a hoe, so as not to affect the root growth of ginseng, so as to pull up the grass at least 5 times a year.

5. Watering

In the past, ginseng was planted without watering, and it was thought that watering made the ginseng root easy to rot. In June of one year in Laiyang, Shandong Province, the weather was particularly dry. They broke the rules and watered the ginseng fields. As a result, the yield of watering was more than double that of the unwatered Radix Glehniae. This fully shows that under dry conditions, proper watering can promote the growth of sand ginseng.
