Introduction of planting methods
Chinese medicine Taizishen, also known as baby ginseng, baby ginseng. Cultivation and reproduction, mainly based on rhizome reproduction. It has the effect of replenishing qi and strengthening the spleen and moistening the lungs. So when does the ginseng grow and harvest the best? What are the planting points? Now we are organizing the planting techniques for everyone as follows:
The time of ginseng is usually in October. It takes 2 to 3 years from seedling to harvest.
The main points of planting of ginseng:
Taizishen is also known as ginseng, medicinal roots. It can be used for the treatment of spleen deficiency, loss of appetite, lung deficiency, cough, palpitations and dry mouth. It is a kind of Chinese medicine for tonic.
Taizishen is a small variety of medicinal materials, with an annual demand of more than 500,000 kilograms. It is mainly produced in Jiangsu and Shandong. At present, the market price of P. chinensis is 55-60 yuan/kg. Generally, the output per hectare is 1200-2250 kg, and the output value per hectare is more than 60,000 yuan.
When planting: Pay attention to the following points:
First, understand the growth habits and choose suitable land
Pseudostellariae is more resistant to cold, and it can be grown in autumn and grows in spring. Hi warm, humid climate, fear of high temperature and strong light exposure, growing at an average temperature of 10-20 °C, growth stagnation when the temperature exceeds 30 °C, plants begin to wither in late June, sleep more summer. The ginseng is planted in the warm and humid Yangtze River basin in winter and spring. When the winter is cold and the spring is dry in the north, the plant growth and development is poor, and the yield of the medicine is not high. During the growing process, it is afraid of being dry and afraid of cockroaches. It is suitable for loose and fertile, well-drained sandy soil rich in humus, and heavy clay and low-lying water are not suitable for planting. Generally, the land is applied to the base fertilizer and the concrete is finely leveled, and then the sorghum is 1.3-1.4 m wide and 17-23 cm high, so that the kneading surface is turtle-shaped.
Second, choose the breeding method, master the seeding technology
It can be propagated by roots, and can also be propagated by seeds. When harvested with seeds, it is harvested one year later.
1. Roots and roots are selected for roots that are complete with bud heads, large body parts, no pests and diseases, and no damage. In the first ten days of October, before the ground is frozen, it is better to use before the end of October. The late ginseng has begun to sprout, and it is easy to touch the buds when planting to affect the emergence of seedlings. The planting depth has a great influence on the yield and quality. Although the roots are too large, the hair roots are small, but the roots are small and the yield is low. The shallow new ginseng is concentrated in the topsoil, and the roots are small and intertwined, and the quality of the medicinal materials is poor. Generally, the trenches are horizontally spaced by 12-15 cm on the flattened raft surface, and the depth of the trench is 6-9 cm. The bud head is upwards according to the plant spacing of 5-7 cm, and is planted in the same direction and slightly inclined. Inside the ditch. After compacting the soil, compact and water it.
2. Seed breeding is generally not used. The seeds of Radix Pseudostellariae are not resistant to storage. It is best to be sown after harvesting, or stored in wet sand for the autumn of the year. In production, the seeds can be used for seedling propagation in the ground. That is, after the ginseng is harvested, the fertilization is carried out immediately, and the soil is simmered. The radish can be planted with radish and green vegetables. The next spring, the seeds of the ginseng seeds sprouted and emerged. And time seedling weeding, planting soybeans in early May, for the ginseng sunshade seedlings, harvesting and planting in autumn.
Third, prevention and control of pests and diseases, reasonable harvesting and processing
Leaf spot disease occurs in April-May, with round brown lesions on the leaf surface, and the plant is dead in severe cases. It can spray 1:1:100 Bordeaux mixture, or 50% carbendazim 500-1000 times solution, every 10 1 time, 2 times in a row; root rot occurs in the high temperature and high humidity season, causing death of rotten roots, should be drained in time after rain, or watered with 50% carbendazim 1000 times solution; leaf wrinkles caused by mosaic disease Shrinkage curl, reduced yield, choose no diseased ginseng, increase phosphorus and potassium fertilizer.
In June, the seedlings were harvested in time after they were withered. They were selected for sunny harvesting, removed stems and leaves, washed with water, and dried directly to be dried. If the roots are placed in the room for 1 to 2 days after the excavation, wash them with water, put them in the boiling water pot for 1 to 3 minutes, then remove the sun and serve as hot.
