Notes on the latest planting of Panax Notoginseng

Tianqi is a traditional Chinese medicine in China, which can replenish qi and blood and improve human immunity. It is not only a kind of Chinese herbal medicine with high medicinal value, but also a common medicinal diet. It is often used to make tea and soup in daily life, and it tastes very good. At present, it is planted in many areas of our country, so what should we pay attention to at 07:00 in the planting field? Let's take a look at the detailed introduction.

1. Growth environment

Tianqi is a shade-loving plant, likes warm winter and cool summer environment, afraid of cold and hot climate, likes humid environment, but afraid of stagnant water, the suitable soil water content is between 20% and 40%. Pay attention to the change of temperature when planting, it should not be higher than 35 degrees in summer, once the temperature is too high, it will grow slowly or stagnant, and if it is heavy, it will die; and in winter, the temperature must not be lower than minus 5 degrees, otherwise it will produce frost damage, and grow best in an environment of 18-25 degrees.

2. Soil preparation and fertilization

Tianqi has loose requirements for soil and strong adaptability, but it is suitable for loose, fertile and well-drained sandy loam, and should not be planted on land with heavy stickiness and low-lying water. At the same time, continuous cropping should be avoided, and the pH value of soil should be between 4.5 and 8. In order to promote the growth and development of Tianqi root system, the soil should be deeply turned over before planting, and the yield of soil sterilization should be carried out. At the same time, 5000 kg of fully mature farm manure per mu should be applied as base fertilizer to maintain soil fertility.

3. Seedling stage management

Seedling management needs to pay attention to water management and weeding work. When the climate is dry, an appropriate amount of watering should be increased, usually once a week, while in case of rainy weather, the amount should be reduced. At the same time, we should also pay attention to the situation of stagnant water in the field, drainage and dampness, so as to avoid rotting roots. Then there is regular weeding, in order to avoid Tian Qi being hurt, it is best to choose artificial weeding, not to use pesticides, so as not to cause drug residues and affect the yield.

4. Pest control

There are many diseases and insect pests in Tianqi, such as blight, root rot, aphids and so on. These diseases mainly occur in the environment of high temperature and humidity, so we must pay attention to the humidity in the field and maintain the permeability of the field. When diseases are found, chlorothalonil and Bordeaux solution should be sprayed in time to control, and dimethoate emulsion should be sprayed when insect pests occur.
