Goji Berry ( [Goji" means [happy") , also called wolfberry, has been used for thousands of years by herbalists in China to protect the liver, help eyesight, boost immune function, improve circulation, and promote longevity and overall well being. It has only recently gained popularity in the west, it has become so polar, in fact, the Time Magazine recently named the Goji berry as [super-fruit" of the year. A big reason why Goji berries have quickly become a favorite nutritional supplement is that its impressive list of ingredients. The Goji berry, also called the wolfberry, is a bright purplish red or purple red berry that comes from a shrub that is native to China. In Asia, goji berries have been eaten for generation in the hope of living longer.

1. Hi-light plants (positive plants) require plenty of sunshine and direct sunlight, and in the absence of sunlight, the plants are weak, poor growth, and low yields. Such as rehmannia, safflower, peony, North Adenophora, Cassia, Astragalus and so on.
2. The shade plant (shade plant) can not tolerate strong sunlight, suitable for growing in the shade environment under the forest, hi diffuse light, reflected light or sooner or later light. Such as ginseng, American ginseng, Coptis, Asarum, Pinellia, Araceae, Panax, Guanzhong and so on. The cultivation of this kind of medicinal plants requires artificial scaffolding or shade cultivation under shade trees.
3. The shade-tolerant plant is the intermediate type of the first two plants and grows best under well-illuminated conditions, but it can also tolerate moderate shade, but different shade tolerance levels are different. Such as Tianmen East, Ophiopogon japonicus, winter flowers, violet and so on.
Different kinds of medicinal plants have different requirements for light intensity at different stages of growth and development. Such as the North Schisandra, Codonopsis, Polygonatum, etc. during the seedlings afraid of strong light. Therefore, we must pay attention to short-term shadowing.
It is of great practical significance to master the requirements of the light intensity of medicinal plants. For example, reasonable intercropping, seedlings, pruning, and proper close planting in the production.
Second, temperature Temperature refers to the air temperature and soil temperature during plant growth. Accumulated temperature has a significant impact on the flowering and solidification of medicinal plants. The types of medicinal plants vary, and the required accumulated temperature is inconsistent. The timely sowing of annual fruit and seed medicinal plants is extremely important. Delayed sowing will often reduce the rate of flowering and seed setting due to insufficient accumulated temperature.
During the growth of medicinal plants, if the atmospheric temperature rises and the atmospheric humidity and the soil moisture are both low, the water in the medicinal plants cannot maintain the normal dynamic balance and is unfavorable to growth.
Different plant species have different temperature requirements. According to different plant growth habits and origin, plants can be divided into four categories: tropical plants, subtropical plants, temperate plants, and frigid plants. To cultivate and introduce a certain kind of Chinese herbal medicine in production, we must first understand the temperature conditions of its place of origin and give necessary conditions to obtain good results. For example, if the chicken oil and cinnamon were originally produced in the south, if they were introduced into the north, they could only be cultivated in the greenhouse or require long-term gradual domestication. To cultivate saffron in Beijing, the temperature required during its growth is exactly the same as that of other local plants. It needs to be planted in mid-September, when other plants have almost stopped growing or have entered the dormancy period, but still grow in winter. It only grew weaker and entered dormancy at the turn of spring and summer the following year. It did not re-emerge until September. In the northern cultivation of saffron, indoor cultivation and outdoor cultivation are combined.
Third, moisture water has very important significance for the growth and development of plants. Without water, there is no plant. Plants are divided according to their adaptation to water.
1. Xerophytic plants These medicinal plants have a well-developed root system or a good "xerobiotic structure" and are suitable for cultivation in areas with high altitude and low rainfall. Such as cactus, sea buckthorn, licorice, astragalus, Tianmendong, aloe, agave, sedum, Baihui Branch medicinal plants.
2. Aquatic plants This type of medicinal plant generally cannot leave the aquatic environment. Such as lotus, duckweed and so on.
3. Wet plants These medicinal plants are suitable for growing in wet conditions such as swamps, floodplains, low-lying lands, wetlands in valleys, and under-forest conditions in humid areas. Such as Alisma, Poria and so on.
4. Most of the medicated plants are medicinal plants. Such as to yellow, Zhejiang shellfish, Codonopsis, Campanulaceae, Corydalis and so on. Such medicinal plants are prone to wither under drought conditions, and are prone to crop damage when there is a lot of moisture. Therefore, in the cultivation of such medicinal plants, proper drainage and irrigation can effectively improve the yield and quality of medicinal materials.
First, light is the source of energy for green plant life activities, and is an indispensable condition for green plants to carry out photosynthesis. As long as the light conditions, the plant can grow and develop normally. According to the requirements of light intensity of various medicinal plants, medicinal plants are divided into three categories.
