What soil does Panax notoginseng grow in, and what climate and soil conditions are needed to grow Pa

Born under the jungle on a hillside. At present, it is mostly cultivated on the slope of the foot of the mountain or the gentle slope of the mound at an altitude of 800 to 1000 m. Panax notoginseng is a perennial root-bearing herbaceous plant with a growth cycle every year.

Generally, Panax notoginseng over two years old has two growth peaks in a growth cycle, the vegetative growth peak from April to June and the reproductive peak from August to October. The germination temperature of Panax notoginseng seeds is 10-30, the optimal temperature is 20, the dormancy period of seeds is 45d-60d, and the seedlings need to undergo a period of low temperature treatment before germinating in the dormant process, and they are very sensitive to light. Tradition believes that 30% of natural light is needed for normal growth and development, so the Panax notoginseng shade shed has the saying of "three percent of the light, seven percent of the shade"; According to the latest research, the most suitable light transmittance of Panax notoginseng shed is 8%-12%, and the growth of more than 17% of Panax notoginseng will be adversely affected!

It is advisable to choose a well-drained gently sloping land with a slope of 5-15 degrees, humus soil or sandy loam soil rich in organic matter. Corn, peanuts or beans should be used for farmland, and Solanaceae should not be used for cropping. The plot is well chosen, it should be leisureed for one to half a year, ploughed many times, 15 to 20 cm deep, to promote soil weathering.

Where conditions permit, grass can be spread and burned before turning the ground or 100 kg of lime per mu can be applied for soil disinfection. For the last time, 5000 kg of fully rotted manure per mu is applied, 50 kg of cake fertilizer, leveling and plowing finely, making furrows, furrows to the south, furrows are wide meters, furrow spacing is 50 150 cm, furrow length depends on the terrain, furrow height is 30-40 cm, furrow circumference is blocked with bamboo poles or wooden sticks, in case the furrow falls, and the furrow surface is tile back shaped.

Panax notoginsengJoy of yinPlants, prefer warm in winter and cool in summer, and the right time for sowing Panax notoginsengIt is from November to March。Planting Panax notoginsengSandy black loam soilPreferably, cover with soil mixed with fertilizer and cover with a layer of turf. Ex-situ planting was carried out after one year.

Adjust the light transmittance of the ceiling appropriately. Remove weeds in the field in a timely manner, fertilize four to eight times a year, and carry out manual watering.

Panax notoginseng planting method:

1. It is better to plant Panax notoginseng in sandy black loam soil, and it is most suitable to plant it on a cool and ventilated hillside. In addition, before planting Panax notoginseng, it is best to build a ceiling with wooden pillars and wooden beams, or build a ceiling with wooden pillars and barbed wire. Remember to evenly sprinkle some well-rotted base fertilizer on the cultivated furrow, and mix well with the soil.

2、.After sowing the seeds, they should be covered with soil mixed with fertilizer, and then covered with a layer of turf, which can help the seeds germinate quickly.

3. After a year of seedling cultivation, it is necessary to plant in situ, and the land ready to transplant Panax notoginseng should also be arranged as well as the seedbed of the seedlings.

4. After planting Panax notoginseng, the light transmittance of the ceiling should be properly adjusted, the light transmittance in spring should be greater than that in autumn and winter, and the light transmittance in summer should be the smallest.

5. During the seedling raising period of Panax notoginseng, during the post-transplanting management period, the weeds in the field should be removed in time, fertilized four to eight times a year, and topdressed about once every one or two months. The fertilization time was after emergence, April, May and July.

6. Panax notoginseng needs to be watered manually during the seedling period (the soil can not be watered if it is night tide), and it is necessary to use a sprinkler to water until the water on the furrow surface, generally watering two to three times a month, and it can be stopped until the rainy season comes.

Panax notoginseng is a shade-loving plant. Prefer warm winter and cool summer environment, afraid of severe cold and heat; Prefer moisture but are afraid of stagnant water, and the soil moisture content should be 22% to 40%. The temperature in summer is not more than 35, and the temperature in winter is not less than minus 5, all of which can grow, and the suitable temperature for growth is 18 25.

Panax notoginseng has no strict requirements for soil and a wide range of adaptation, but it is better to have loose soil and well-drained sandy loam soil. It is not suitable for planting in areas that are too sticky, too sandy and low-lying and easy to accumulate water. Avoid continuous cropping, soil pH.

Panax notoginseng has only one palmate compound leaf; Biennials have 2-3 palmate compound leaves, each composed of 5 7 leaflets, which begin to sprout and flower; In three or four years, Panax notoginseng generally has 3 5 palmate compound leaves, each of which is mostly composed of 7 leaflets, and a few have as many as 9 leaflets. Panax notoginseng that is more than five years old has up to 6 compound leaves. The number of palmate-shaped compound leaves in each year is affected by the growth and development conditions, and the nutrition is sufficient, the development conditions are suitable, and the number of palmate-shaped compound leaves is large.

Panax notoginseng is born in each year, and the seedlings emerge in February and March in the production area, and the seedling emergence period is 10 to 15 days. Panax notoginseng will enter the leaf development period after the growth, the stem and leaf growth is faster at the beginning of the leaf development, usually 15 20 days plant height can reach the normal plant height of 2 3, and then the stem and leaf growth is slow, with the germination of the seedlings grow out of the one-time growth, once the formed spores grow out of the stem and leaf are damaged, there is no seedling on the ground.

Panax notoginseng is sensitive to light, likes oblique, scattering, and diffuse light, and avoids strong light. Generally, the light transmittance should be 30%. If the light is too weak, the plant grows, the leaves are soft, the taproot grows slowly, and it is easy to get disease; If the light is too strong, the plant is short and the leaves are easily burned.

Panax notoginseng seeds have post-ripening and can be stored under moist conditions in order to complete physiological post-ripening and germination. The appropriate temperature for seed germination is about 20. The lifespan of seeds under natural conditions is about 15 days, and the seeds lose their vitality once they are dried, so they should be sown with harvest or layered.

In fact, the requirements for the soil of notoginseng are not very strict, generally except for the overly acidic soil and clay soil, other types of soil can be planted normally. However, in order to ensure the normal growth of Panax notoginseng and improve the yield and quality of Panax notoginseng, it is necessary to ensure that the soil is soft and rich in humus. It is best to use sandy soil as the mainstay, maintain a certain inclination, and have not planted Panax notoginseng in eight years, and its pH is controlled at about it.

Panax notoginseng does not have strict requirements for soil pH, and can be adapted to neutral, slightly acidic and slightly alkaline. It grows well between loose, well-drained, humus-rich sandy loam, calcareous light clay loam and red loam, pH 4 5 8.

Panax notoginseng is warm in winter and cool in summer, and the climate with small temperature changes in four seasons requires an average annual temperature of 16 21, the average monthly temperature in January is not less than 4, and the average monthly temperature in July is not more than 34, under the conditions of low latitude of the main producing areas, it is most suitable to be cultivated in the mountainous area at an altitude of 800 1600m, if it exceeds 1700m height, the fruit is not easy to ripen.

Panax notoginseng is a shade plant, which is very sensitive to light, and the leaves will be burned when exposed to strong direct light. But it prefers scattered light and low light. Different growth periods have different requirements for light, generally requiring shade of 40 70.

If the shade is too high, the plants are long, delicate, and prone to disease, with low yield and poor quality. If the shade is too low, the plant will grow slowly, dwarf, the leaves will be old, and even sunburn will appear.

Panax notoginseng has strict requirements for moisture, likes moisture, is afraid of drought, but is afraid of waterlogging. The relative humidity of the air is required to be 70 85; The soil moisture content was optimally 20 40; Drought occurs below 17, and flooding occurs above 40. The relative humidity of the air should be 70 85.

Special attention should be paid to strengthening the light and reasonably adjusting the dry and humidity in the cultivation of Panax notoginseng. Breeding can use Bika granular fertilizer as base fertilizer.

The climate and soil required for the third phase of planting have special requirements, he is only suitable for the weather in the south, and the north is not planted with Panax notoginseng, which needs to be the temperature and humidity of the soil.

The following conditions are generally met for planting Panax notoginseng: Panax notoginseng is a negative plant, which needs certain shade conditions to grow, is sensitive to light, likes scattered light, usually 8%-20% of natural light, avoids direct sunlight, the light is too strong, the plant is short, and the leaves are easy to burn. Panax notoginseng is a kind of moisture-loving, drought-tolerant, waterlogging plant, growth and development needs a humid environment, the average annual precipitation is more than 1200 mm, the relative humidity of the air is 70%-85%, the leaves of the air humidity are too low, and the optimal moisture content of the soil is 25%-30%. �

The rhizome of the Panax notoginseng plant is erect, the height is about 60 cm, the stem color is dark green, the flowers are light yellow, Panax notoginseng is suitable for planting to loose and fertile acidic soil, and the planted plants can be placed in a sunny place indoors, and they can be watered every 10 days or so, so that the soil is in a moist state.

1. Plant introduction

Panax notoginseng plants can reach 60 cm high, the taproot is fleshy, spindle shaped, the stem is dark green, the petiole has stripes, the flowering period of the Panax notoginseng plant is July to August every year, the flowers are solitary at the top of the stem, the flowers are petite, but the number is numerous, there are about 100 flowers.

2. Provide soil

Panax notoginseng plants like acidic soil, can be planted into humus, garden soil mixed with the soil, before planting, can also be mixed into the soil coarse sand, improve soil permeability and drainage, but also for the soil to add base fertilizer, promote the better growth of notoginseng.

3. Growth environment

When maintaining Panax notoginseng plants, it needs to be placed in a ventilated and diffused light place to provide no less than 5 hours of scattered light for the plants every day.

4. Apply moisture

In the process of maintaining Panax notoginseng plants, it is necessary to observe the changes in the soil, when the soil surface is white, it is necessary to water Panax notoginseng immediately, so that the soil is in a moist state, and pay attention to not make the chassis have stagnant water, otherwise it will lead to the rot of the root system of Panax notoginseng.

Panax notoginseng has relatively high requirements for soil, you should choose some fertile soil, or choose some soil with good air permeability, and do a good job of insect control after planting, because Panax notoginseng is very insect-catching, and you should usually do a good job of watering, and the temperature should be kept at about 25 degrees, so that Panax notoginseng will grow particularly well.

When planting, we must pay attention to the acidity and alkalinity of the soil, try to be more alkaline, and we must pay attention to humidity and temperature, and at the same time we should ensure the nutritional value of the soil.

The requirements for soil are still relatively high. It is best to choose sandy soil, but also need to ensure the fertility of the soil, timely watering and fertilization, strengthen water and fertilizer management, but also should maintain sufficient light, do a good job of loosening the soil, avoid insect pests, spray pesticides regularly, and do a good job of drainage and ventilation.

First of all, the soil must have a certain amount of organic matter, it must be fertile, it must have a certain humidity, the acidity and alkali must be balanced, and it must be loose and breathable.
