How to plant and manage Rehmannia glutinosa? Easily master the planting technology of Rehmannia glutinosa at 5: 00.

Rehmannia glutinosa is a kind of traditional Chinese medicine, which is mainly distributed in Zhejiang, southwest, Hubei and other areas. Rehmannia glutinosa has the effect of treating palmar heat, blood deficiency and internal heat, and the well-known Liuwei Dihuang pill is made from Rehmannia glutinosa. Because of the great market demand, many growers of Rehmannia glutinosa want to increase the output, so how should we plant so that we can increase the output? The following is to help you understand some aspects that you should pay attention to in planting Rehmannia glutinosa.

Soil preparation and fertilization

Rehmannia glutinosa likes the planting environment with plenty of sunshine and warm temperature. There are also some requirements for the land, can not be planted in the soil is relatively hard, will lead to underground rhizome deformity, planting Rehmannia glutinosa in low-lying areas will be too wet roots lead to rotten roots, so to choose a place with deep soil layer for planting. After selecting the geology suitable for planting, the whole field is turned over before planting Rehmannia glutinosa, remove harmful impurities and pests as much as possible, and then spread the base fertilizer on the soil before sowing.

Scientific sowing

Now science is more and more developed, so there will be some more scientific and correct planting methods to help us improve the yield and quality of plants. The general planting method is seed sowing and tuber planting, which should be disinfected and sown before planting. When planting tubers, we should choose some strong vital signs to plant to ensure the survival rate of Rehmannia glutinosa. On the other hand, seed sowing needs to promote the emergence speed of seeds by drying and soaking seeds, so as to ensure that the seedlings can be managed conveniently and uniformly. The correct and scientific planting methods should be chosen in order to improve the quality and yield of Rehmannia glutinosa cultivation.

Reasonable close planting

The density between Rehmannia glutinosa planting also needs to be paid attention to. It is generally managed according to the fertility of the soil. If the land is not fertile and is relatively barren, the distance between each plant should be about five centimeters apart. If it is a more fertile soil, the distance between the plants should be about 15 centimeters apart. Planting according to the plant density reasonably can ensure the nutrient absorption of Rehmannia glutinosa and increase the yield.

Field management

When planting Rehmannia glutinosa, we should pay more attention to field management and focus on the emergence of Rehmannia glutinosa seedlings. Because the root system of Rehmannia glutinosa is relatively shallow, the general method of removing weeds will hurt the rhizome of Rehmannia glutinosa, so we can only pull out the weeds near Rehmannia glutinosa by hand. Rehmannia glutinosa is a variety of plants that need a lot of nutrients, so it is necessary to fertilize twice during planting, but Rehmannia glutinosa does not have high requirements for water, so normal watering is fine.

Pest control

During planting, we should also pay great attention to the phenomenon of diseases and insect pests. In general, diseases and insect pests are caused by high humidity, and once germs are produced, they will destroy the stems and leaves of Rehmannia glutinosa and even the whole land. So we can use Bordeaux liquid and carbendazim to prevent and control in advance to ensure the quality and yield of Rehmannia glutinosa.
