What is the planting technology of Panax notoginseng medicinal herbs?

1. Land selection and land preparation: It is advisable to choose gently sloping land with good drainage, humus soil or sandy loam soil rich in organic matter. Repeated ploughing, 15 to a depth of 20 cm, promotes the weathering of the soil.

Every time it is turned, the foot fertilizer is applied, and the new high-fat film is sprayed to disinfect the soil, so as to protect fertilizer and moisture, which can repel underground diseases and insects and isolate virus infection.

2. Seed treatment: select excellent varieties, from October to November every year, select 3-4 year-old plants to produce full shade ripe and red fruits, pick them, put them in a bamboo sieve, rub off the peel, wash, and dry the surface moisture. Soak seeds with 800 times liquid of new high-lipid film for 10 minutes for disinfection treatment (can be mixed with seed coating agent) to repel underground pests and diseases, isolate virus infection, do not affect germination and swelling function, strengthen respiratory intensity, improve seed germination rate, and sow seeds in time.

3. Seedling management and transplanting: timely watering, regular weeding, a small amount of chasing at the seedling stage, transplanting after the seedlings are full, and it is required to pick up seedlings, select seedlings, and transplant at the same time. When rooting, it is strictly prevented from damaging the roots and spores.

When selecting seedlings, disease, injury, and weak seedlings should be eliminated, and they should be cultivated at different levels. Seedlings should be disinfected before planting. Dip the roots with 300 times more zinc, remove it immediately after dipping and plant it in time.

4. Growth management: Panax notoginseng is a shallow root plant, which should be weeded and cultivated in time, and should be frequently watered to keep the furrow moist, and should be sprayed when watering, not splashed, otherwise it will cause the plant to lodging. Panax notoginseng likes yin, artificial cultivation needs to build a shed for shade, Panax notoginseng topdressing to master the principle of "many times a small amount", in order to prevent the needless consumption of nutrients, concentrate on the growth of underground roots, when the flower sprouts appear in July, remove all the flower sprouts, and spray the herbs on the foliar surface Root Daling, promote the foliar photosynthesis products (nutrients) to the root system, improve the nutrient conversion rate and loosen the soil ability, make the rhizome expand rapidly, greatly improve the medicinal content, and improve the yield of Panax notoginseng.

5. Common pests and diseases include blight, anthracnose, root rot, blight, aphids, red spiders, and scale insects. Spraying targeted drugs and new high-lipid film greatly improves the utilization rate of active ingredients of pesticides, is not afraid of evaporation from sun exposure, can adjust the absorption of water, and prevents drought and rain.

Panax notoginseng transplanting can be divided into winter planting and spring planting. Winter planting is better, winter planting uses 1-year-old seedlings, generally transplanted from late November to December, and completed before dormant bud germination. First of all, the seedlings should be dug up carefully so as not to hurt the roots.

Then, it is planted according to large, medium and small grades, which is conducive to the emergence of seedlings neatly and is easy to manage. Before planting, cut off the yellow leaves of the seedlings, soak them in a new high-fat film (which can repel underground pests and diseases, isolate virus infection, and improve the survival rate of plants) and dry them before planting. When planting, on the planted ground, according to the large, medium and small seedlings, respectively, according to the row spacing is:

17 17 cm, 17 13 cm, 13 13 cm open holes, the depth of the hole is 3 cm, and each hole is placed into 1 Panax notoginseng seedling. Place the bud heads in the hole slope downhill. Flat ground, can also be on the furrow surface to open a horizontal ditch, 3 5 cm deep, according to the row of plant spacing 15 15 cm, the seedlings evenly swing into the ditch.

After planting, cover with fine manure soil, thick centimeters, and finally cover the furrow with grass, and the thickness is not seen in the soil fertilizer; Then pour it 1 more time to penetrate the water. Planted in strips, with a row spacing of 15 cm each. About 20,000 seedlings need to be planted per mu.

Timely spraying of the new high-lipid film after the disaster can effectively prevent the water on the ground from evaporating, the moisture of the seedling body from transpiring, isolate pests and diseases, shorten the seedling period, quickly adapt to the new environment, and grow healthily.

1. Sowing time.

Panax notoginseng is a relatively cold-tolerant plant, many people do not know how to plant notoginseng, usually we can sow in winter 11 and December, and can also be sown in spring 3 and April, it needs to be decided according to the planting area and climate, sowing and reproducing in these two time periods, and the seed survival rate of Panax notoginseng is the highest.

2. Seed treatment.

Seeds can be collected in October and November every year, or you can buy the seeds directly, and the seeds need to be soaked in 1000:1 dilution carbendazim to prevent pests and diseases during the planting process.

3. Select the soil.

Every time you plant Panax notoginseng, do not use clay to plant, it is best to choose deep soil, loose and drainage, high fertility of the soil planting, we can sow the seeds of Panax notoginseng into the black soil, which can be added in an appropriate amount of some Bika granular fertilizer, increase the organic matter of the soil.

4. Sow seeds and germinate.

The treated Panax notoginseng seeds are sprinkled on the soil, covered with a layer of about 1cm of soil, a little organic fertilizer can be applied appropriately, some water is sprayed on the soil, and then a layer of turf is spread, which can promote the seeds of Panax notoginseng to take root and germinate quickly.

5. Seeding management.

After the seeds of notoginseng are sown, they need to be placed in a scattered place to breed, and they should be watered every 5 7 days, and organic fertilizer should be applied every 20 days or so, and the temperature should be controlled at 15, and after waiting for 1 2 months, the seeds of notoginseng will take root and germinate, and then be carefully cultivated in a place with sufficient sunlight.

Panax notoginseng planting method:

First, the choice of garden

The quality of the soil directly affects the output of Panax notoginseng, if the soil quality is very good, the growth environment is very good, then the staff will be much easier to take care of, and the output will also increase. Panax notoginseng has very few requirements for soil quality, and there is no problem with sandy soil, yellow clay, clay, and sandy soil. Panax notoginseng is freeze-resistant, dry-resistant, waterlogging-resistant, planting land requires flat terrain, the land should be drained smoothly, the rainfall gradually increases, and the water should be drained in time, otherwise it is easy to die in a large area.

The land is mainly conducive to drainage, the soil quality is almost enough, and the sunshine time is sufficient.

2. Land preparation

Cultivated land:

Panax notoginseng responds quickly to fertilizer, the soil fertilizer is sufficient, the development can be vigorous, and the plant body is strong. But a small part of the soil of the field is some fertilizer about the same land, so if you want to produce more, you should apply enough green manure before sowing, and sprinkle 3 6t cow dung and horse manure on one acre of land, and turn the soil and deep plough once after using fertilizer, and rake it once, so that the soil and fertilizer are fully and evenly mixed together, and there is no big soil lump, which is conducive to sowing and germination.

Zuo Qi:

In order to facilitate the maintenance and management of Panax notoginseng in the growth period from beginning to end, such as watering, weeds removal, fertilization, etc., it is recommended that you make the land into a fixed standard meter wide furrow, with a total length of 16 22 meters, and the actual situation is determined according to the field.

3. Sowing

Panax notoginseng seed particle size is general, germination rate is relatively good, before sowing can be moderate germination treatment, the method is actually very simple, use cold water to soak for a day, after taking out to dry the surface can be made, sowing depth is moderate or shallow, covering the depth of the soil is not more than 5 cm. Generally, strip sowing, the condition of choosing a small wind, mixing the seeds of Panax notoginseng into the wet sand, evenly sprinkled on the soil, after sowing seeds, you can use manual soil or machine soil covering soil, after covering the soil, irrigate once, about 5 9 days can germinate.

Fourth, seedling management

There is only one thing to manage during the growth period of Panax notoginseng, it has few insect pests, and the growth situation is good. The maximum work is only watering, removing weeds and pests and diseases, in the peak growth of Panax notoginseng, requiring a lot of water and fertilizer, during this time, can be applied 45 kg of fertilizer per acre, during the peak growth of Panax notoginseng also requires more water, during which it is necessary to decide whether it needs to be watered according to the meteorological conditions.

Panax notoginseng is a perennial herbaceous plant that has a growth cycle every year. Generally speaking, Panax notoginseng has two growth peaks in a growth cycle, that is, the vegetative growth peak from April to June and the reproductive growth peak from August to October. The germination temperature of Panax notoginseng seeds is 10-30, the optimal temperature is 20, and the dormancy period of the seeds is 45-60 days.

Seedlings need a period of low temperature treatment to germinate during the dormant period and are very sensitive to light. Traditionally, 30% of natural light is needed for normal growth and development, so Panax notoginseng canopy has the saying of "30% light transmission, 70% shade"; According to the latest research.

The most suitable light transmittance of Panax notoginseng shed is 8%-12%, and more than 17% will adversely affect the growth of Panax notoginseng! It takes more than 3 years to sow and harvest Panax notoginseng; The roots of Panax notoginseng are usually used as seedlings and can flower and bear fruit from the second year onwards. They usually bloom in July, bloom in August, bear fruit in September, and ripen in batches from October to November.

Wenshan's special natural environment: Wenshan, the main production area of Yunnan Panax notoginseng, is located on a low-latitude plateau. Climatic characteristics: long summers and warm winters, abundant heat, small annual temperature differences, annual average temperature, Yunnan Meteorological Bureau Data Room, 1982).

Except for the weather from mid-December to mid-February, the average annual minimum temperature is 0-2 when daily temperatures and low temperatures occur. In summer, due to the concentration of precipitation, solar radiation decreases significantly, and the average temperature from June to August is . The suitable temperature and moisture conditions provide a superior natural environment for the growth and development of Panax notoginseng.

In winter, the average monthly temperature is 11, and the growth of the aboveground part has stopped, but the ground temperature of 5cm is still 14 (regional average), which is also the reason why the stems and leaves of Panax notoginseng can still survive in winter.

Higher ground temperature is conducive to the accumulation of root nutrients, especially conducive to the morphological development of seeds planted in the soil, and the seed post-maturity period is naturally completed in winter, which is extremely beneficial to the seedling raising and seed emergence rate of Panax notoginseng, and this unique natural ecological environment is a favorable factor for the production and development of Panax notoginseng in Wenshan Prefecture. Influence of temperature on Panax notoginseng: The landform of Panax notoginseng is complex and the terrain is undulating, resulting in a significant vertical difference in temperature.

In winter and spring (December to April) and late summer and early autumn (August to October), the intrusion of cold air from atmospheric circulation causes short-term and local frost and low temperature disasters, especially low temperature damage.

Be sure to pay attention to control the temperature, the germination temperature of the seeds should be kept at about 10 30, the best temperature should be kept at about 20, the dormancy period of the seeds is generally 45 60 days, during the dormancy period must be treated at low temperature, the light time should not be too long, the light transmittance should be kept at about 8% 12%, and the place of planting must be selected at low latitudes and high plains.

The first is to choose sunny slopes for planting, the second is to choose sandy black loam, the third is to choose excellent varieties, and the fourth is to water more and weeds in time.

To plant Panax notoginseng, we must first choose good varieties, find highlands with good drainage, and dig planting pits. Seedling management needs to control the appropriate temperature and humidity. Daily management should pay attention to the prevention and control of pests and diseases.

When planting notoginseng, it should be noted that the most different thing about notoginseng and other plants is that notoginseng likes to grow in the shade, and direct sunlight is a harm to its growth. Therefore, in the planting process of Panax notoginseng, it is necessary to avoid direct sunlight, and according to the growth of Panax notoginseng, moderate shading. There is also to prevent the pests and diseases of Panax notoginseng, the diseases include Panax notoginseng yellow rust, Panax notoginseng blight, Panax notoginseng black spot disease, insect pests and short-bearded mites, peach aphids, bee slugs, ground old cattle and tigers, rodent infestation, etc.

Regarding insect pests, physical prevention and control methods can be adopted, for example, after sowing and watering, the method of covering silver-gray mulch film is adopted, so that some insects have a response to silver-gray avoidance, on the other hand, the temperature of the soil increases after covering the mulch, and the eggs and pupae of insects existing in the soil have the effect of elimination. At the same time, it also has good effects such as water retention and fertilizer saving.

We must pay attention to the selection of soil, we must pay attention to the situation of sunlight, pay attention to the temperature, and we must do a good job of drainage system in advance, we must choose the right seeds for planting, and the management must be managed in accordance with scientific methods, and we must pay attention to the prevention and control of bacteria and pests.

Planting conditions: Shading measures should be taken when planting Panax notoginseng, and well-drained, gently sloping humus-rich soil should be provided. Seed treatment:

The seeds were soaked in 800 times the solution of the new high-lipid film, and the beam infiltration type was disinfected to improve the disease resistance of the seeds. Field management: Weeding is required regularly at the seedling stage to prevent weeds from competing with the plants for nutrients.

1. Planting conditions

Panax notoginseng is a negative plant and is sensitive to light, so when planting, it is necessary to do a good job of shading measures to avoid strong light burning the leaves, resulting in dwarf plants, and notoginseng likes a moist environment, is not tolerant to drought and severe cold, and is suitable for growing in well-drained, gently sloping and humus-rich soil.

2. Seed treatment.

From October to November every year, select high-quality Panax notoginseng fruits, remove their skins, wash them with water, and put them in a ventilated place to dry them, and then soak the seeds in the new high-fat film 800 times the liquid for disinfection treatment, improve the disease resistance of the seeds, and strengthen the strength of the root system.

3. Field management

In the seedling stage of Panax notoginseng, weeding needs to be carried out regularly, so as not to compete with weeds and plants for nutrients, and take transplanting measures after the seedlings, and when the seedlings rise, we must avoid damaging the spores and roots of Panax notoginseng, so as not to affect the growth of plants, in addition to the later maintenance process, timely weeding, soil cultivation.
