It is mainly used to treat diseases such as hematemesis, traumatic bleeding and dysmenorrhea. Here is an introduction to the cultivation techniques of Chinese herbal medicine "Puhuang".

I. planting site management

Pollen Typhae has the characteristics of high temperature, high humidity, low temperature tolerance and strong adaptability in the west. Puhuang does not have high requirements for the planting environment. Generally, marshes, lakes, shoals and paddy fields with deep silt and rich organic matter in the soil layer can be selected, and the soil had better be loose and solid, so it is convenient for the management of water in the field and the arrangement of soil fertilizer. The base fertilizer is mainly manure and urine, of course, it can also be replaced by other organic fertilizers, and finally leveling the land, it can be planted in Puhuang.

II. Propagation and cultivation techniques

Puhuang is generally carried out in the way of ramet propagation, and seed reproduction is used in some places, but it is mainly ramet propagation. The best time for reproduction is from March to April every year, but it can be planted between March and June, that is to say, when the temperature is 15 degrees Celsius or above, it can be planted. Before planting, select robust ramets for planting. Then hole planting was carried out according to the distance of row and plant spacing of 50cm, and two small plants were planted in each hole.

III. Field management

After planting, it is necessary to carry out field management, the most important of which is water management. after planting, the water in the field should not be too much or too shallow, generally around 15cm in the early stage, which can increase the surface temperature, thus improve the survival rate, do not make the soil drought, affect the normal growth of Pollen Typhae, with the growth of Pollen Typhae, the water level can be gradually increased. But the deepest cannot exceed 1.2m, wait until one month after planting, if the growth rate slows down or the growth is stunted, it needs to be fertilized in time, usually based on the rotten farm manure, according to the specific situation to control the amount of fertilizer, in the process of the growth of Pollen Typhae, it is necessary to sort out some disorderly and overgrown Puhuang, and if necessary, it is best to change the field to plant. Pay attention to weeding and reduce the consumption of nutrients.

The harvest of Pollen Typhae should be reasonable. Generally, the upper part of Puhuang is cut off with a knife, or pulled out by hand, so as not to hurt the root of Puhuang during harvest, so as not to affect the yield and quality of the coming year.
