How to plant the latest Puhuang

Puhuang is the dried pollen of Typha angustifolia, Typha orientalis and similar plants. It is a kind of traditional Chinese medicine. Puhuang in China is mainly produced in Zhejiang, Jiangsu, Anhui, Hubei and other places, mainly used for the treatment of hematemesis, traumatic bleeding, amenorrhea and dysmenorrhea. So do you know how to grow Puhuang? Today, let's follow the editor to learn about its cultivation techniques.

1. Planting site management

Puhuang has the characteristics of high temperature, high humidity, low temperature resistance and strong adaptability. Pu Huang does not have high requirements for the planting environment, generally choosing marshes, lakes, shoals and paddy fields with deep silt and rich organic matter in the soil layer. In addition, the soil had better be loose and solid, which is convenient for the management of water in the field and the arrangement of soil fertilizer. Soil preparation should be carried out together with base fertilizer, which is mainly based on manure and urine, of course, it can also be replaced by other organic fertilizers, and finally leveling the land, the planting of Puhuang can be carried out.

2. Propagation and cultivation techniques

Puhuang is generally carried out in the way of ramet propagation, of course, seed reproduction is used in some places, but it is mainly ramet propagation. The best time to breed 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 or above, we can plant. Before planting, we should select robust ramets for planting, and then plant holes at a distance of 50 centimeters between rows and plants, and two small plants are generally planted in each hole.

3. Field management

After planting Puhuang, we need 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, nor should it be too shallow, which is generally about 15 centimeters in the early stage, which can increase the surface temperature and thus improve the survival rate of Puhuang, but what should be paid attention to is not to make the soil drought. affect the normal growth of Pollen Typhae. Then with the growth of Puhuang, we can gradually raise the water level, but the maximum depth can not exceed 1.2 meters. Wait until a month after planting, if the growth rate of Puhuang slows down or stunted, it needs to be topdressing in time, generally based on rotten farm manure, according to the specific situation to control the amount of fertilizer. Finally, in the process of the growth of Pollen Typhae, we have to sort out some cluttered and overgrown Puhuang, and if necessary, it is best to change fields for planting, and of course, we should pay attention to weeding and reduce the consumption of nutrients.

4. Harvesting and disease prevention

Pu Huang is the most common in the growth of aphids, we can usually use dimethoate for control, but it is important to note that no insecticide can be sprayed within half a month before harvest. The second is that the harvest of Puhuang should be reasonable, generally cutting off the upper part of Puhuang with a knife, or pulling it out by hand. What we also need to pay attention to when harvesting is not to hurt the root of Puhuang, so as not to affect the output and quality of the coming year.

Pu Huang is not only a blindly traditional Chinese medicine, in fact, it can also be eaten as a vegetable, but its main edible part is its fresh stems and leaves, which is rich in protein and other nutrients, and is also a very healthy green vegetable.
