Matters needing attention in planting Rehmannia glutinosa

With the improvement of economic level, the application of traditional Chinese medicine is more and more widely, and the demand for all kinds of traditional Chinese medicine is gradually increasing. Rehmannia glutinosa has the effects of cardiotonic, diuretic, analgesic, hypoglycemic and liver protection. it is one of the commonly used medicinal materials and is cultivated all over the country. So what should be paid attention to when planting Rehmannia glutinosa? Let's take a look.

1. Parcel selection

Rehmannia glutinosa has strict requirements for soil. When planting, it is appropriate to choose sandy loam with deep soil layer, loose and fertile soil and good drainage, requiring neutral or slightly acidic acidity and the best content of organic matter. The land with heavy soil viscosity and low-lying stagnant water should not be planted, and Rehmannia glutinosa should not be replanted, which should also be paid attention to when selecting land. The previous crop is the most Gramineae plant, so it is not suitable to choose the plots of cotton, sesame, beans and melons.

2. Seedling stage management

The middle ploughing and weeding of Rehmannia glutinosa should not be carried out too much, generally only twice in the seedling stage, the first time in the seedling 4-5 meters, shallow hoe to loosen the soil, so as not to damage the root system of the seedling, resulting in the death of the seedling and manual pulling of weeds; the second time when the seedling grows to the model above 10cm, repeat the same operation. There is no need for intermediate ploughing in the future, but weeding can be carried out according to the weeds in the field. In addition, it is necessary to combine two intertillage to seedling and seedling supplement, irregular emergence is a common problem in Rehmannia glutinosa production, improve the way of seedling supplement and make it grow neatly.

3. Water management

Rehmannia glutinosa has a very high demand for water. In the early days, it requires low soil water content, between 10% and 25%. In the middle and later stages of growth, that is, when the tuber expands, it is necessary to keep the soil moist, but not too wet. Its roots are less and its ability to absorb water is weak, so it will wither in case of drought, but the stagnant water will make its roots rot, so pay attention to it.

4. Picking buds

A month after the emergence of Rehmannia glutinosa, its underground rhizome will grow 2-3 buds, these later buds must be pulled out, each plant can leave a strong seedling. Some seedlings may have a string of bark roots because of the variety, and there will also be a lot of adventitious buds on these roots, which consume a lot of nutrients and affect plant growth, so they should be pulled out in time. In addition, when the plants on the ground begin to sob and blossom, in order to save nutrients, the buds should be removed in time to increase yield.
