How to plant Polygonatum polygonatum and how to plant Polygonatum polygonatum

1.The planting of Polygonatum polygonatum needs to be loose and fertile, with good air permeability and drainage. You can use humus, garden soil, and humus.

Before sowing, turn deeply, apply two tons of farmhouse fertilizer per mu in combination with land preparation, turn it into the soil as the base fertilizer, and then rake it flat to make a wide rice furrow. 2.Planting method (1) sowing planting.

Choose seeds that are growing well and sow them in August. The ratio of sand to sand should be 1:3, maintaining a uniform row spacing, and the optimal range is 12-15.

Cover the seeds with a layer of soil and press the soil with both hands to make it stable and firm. (2) Rhizome planting: select the rhizome part with good growth, and cultivate it after disinfection with carbendazim, and keep the spacing at 15-20.

After mulching, dilute nitrogen fertilizer is used to provide nutrients to the stalks. Water again, about 500ml, to keep the soil moist. 3.

Light temperature: Huangjing's light requirement is to ensure more than 5 hours of light every day. The temperature is above 20 degrees. In summer, the temperature is high, so avoid direct sunlight.

In winter, the temperature is low, and light can be used for photosynthesis at noon. The temperature should not be lower than 10 degrees Celsius to avoid freezing damage. 4.

Polygonatum polygonatum needs more water in spring and autumn because it is in the growing season and needs to be watered every 3-5 days. Long-term fertilization is the use of nitrogen, phosphorus and potassium compound fertilizer, which is applied every 5-7 days. 5.

The growth of disease herbicide Polygonatum polygonatum will be affected by diseases such as anthracnose, and can be disinfected with pesticides and carbendazim. Weeds should be pulled out in spring and autumn so as not to hinder the growth of Polygonatum polygonatum

1. Site selection and land preparation: Choose a site with sufficient sunlight for planting Polygonatum polygonatum, and deepen the depth of 20 cm, and apply well-rotted farmhouse fertilizer. 2. Sowing and planting:

Select undamaged young stems, cut them into small sections and bury them in the soil at a plant spacing of 20 cm. 3. Disease prevention and control: Yellow essence leaf spot should be treated with Dysen zinc, and Bordeaux liquid should be used for black spot disease.

1. Site selection and land preparation

Polygonatum polygonatum has a certain need for light, so you can choose a field with sufficient sunlight and nutrients when planting, and use a hoe to plough the soil for 20 cm to remove grass roots and gravel from it, and then bury the soil with well-rotted farm manure or animal manure, wait for a week and then plant Polygonatum polygonatum polygonatum

2. Sowing and planting:

Polygonatum polygonatum can be sown and planted, first dig out the healthy and pest-free young stems from the soil, cut them into several small sections, and then put them in a cool and ventilated environment to dry the wounds, and then bury the stems in the soil with a row spacing of 30 cm and a plant spacing of 20 cm, and finally cover with a thin layer of soil.

3. Disease prevention and control

The common diseases of Polygonatum polygonatum are leaf spot, black spot, after the disease the plant will have a phenomenon of long spots, affecting the normal growth, for leaf spot, you can use the diluted solution of zeb zinc for spraying**, after suffering from black spot, you should spray Bordeaux solution once a week, so that the plant can resume healthy growth.

How is Polygonatum polygonatum grown? Explain in detail the cultivation technology of Polygonatum polygonatum seeds and seedlings.

1. Land selection and land preparation: Plant yellow selects moist and shady plots, first prepares the land to ensure that the plots are soft, and also makes furrows. 2. Planting method:

The rhizomes can be planted directly, and the treated young stems can be dried for wounds, planted according to the plant row spacing of 50-50 cm, and covered with soil and watered. You can also use the sowing method, according to the row spacing of 12-15 cm evenly sprinkled seeds in the shallow ditch. 3. Field management:

Weeding in the early stage, and soil if necessary. Timely watering and top dressing during growth.

1. Land selection and land preparation.

Choose moist and well-shaded plots, and the soil should be loam or sandy loam with loose texture and good water retention. Before sowing, turn it deep 1 time, apply 2000 kg of farm fertilizer per mu in combination with land preparation, turn it into the soil as base fertilizer, and then rake it finely and level, make a furrow, and the furrow is wide and meter.

2. Reproduction methods.

Rhizome propagation: in late autumn or early spring around the end of March, select 1-2 years of robust, disease-free plant rhizomes, select the young part of the apex, cut into several segments, each section has 3 4 sections, the wound is slightly dried, according to the row spacing of 22 24 cm, the plant spacing is 10 16 cm, and the depth is 5 cm, after covering the soil, it is slightly suppressed and watered, and then watered once every 3 5 days to keep the soil moist. When planting in late autumn, cover with some circle fertilizer and grass to keep warm after frosting.

Seed propagation: After the seeds are mature in August, the mature and full seeds are selected and immediately treated with sand: 1 part of seeds, 3 parts of sandy soil and mix evenly.

Store in a pit 30 cm deep in the shade and keep it moist. In late March of the second year, the seeds are sieved out, evenly sown into the shallow ditch of the furrow surface according to the row spacing of 12 15 cm, covered with soil about centimeters, watered after a little pressing, and covered with a layer of grass to moisturize. Remove the cover grass before emergence, when the seedling height is 6 9 cm, the seedlings can be appropriately spaced in too dense places, and transplanted after l years.

In order to meet the shading conditions required for the growth of Polygonatum polygonatum polygonatum (Polygonatum polygonatum vulgaris), corn can be planted on the ridges.

3. Field management:

In the early stage of growth, it is necessary to often cultivate and weed, and carry out 1 time a year in each month, and it is advisable to hoe shallowly and cultivate the soil appropriately; Pull the weeds later. In case of drought or planting in a sunny and arid place, it needs to be watered in time. Every year, combined with cultivating and weeding for top dressing, after the first three times of tillage, 1500 kg of soil miscellaneous fertilizer is applied per mu, 50 kg of superphosphate and 50 kg of cake fertilizer, mixed and mixed evenly after ditching between the rows, and covering soil and fertilizer after application.

Polygonatum avoids water and shade, and should pay attention to drainage and intercropping corn.

Polygonatum polygonatum is planted. Pest and disease control.

1. Black spot disease: more than spring, summer and autumn, which is harmful to leaves. Prevention and control methods: clear the garden at harvest time to eliminate disease and residues; Spray 1:1:100 Bordeaux solution in the early stage, once every 7 days, 3 times in a row.

2. Grubs: take larvae as the pest, damage the roots, bite off the seedlings or chew the roots of the seedlings, causing broken seedlings or root cavities, and the harm is serious. Prevention and control methods:

75 phosphine emulsifiable concentrate can be used for seed dressing; Or in the field occurrence period, water with 90 trichlorfon 1000 times.

1. Polygonatum polygonatum planting varieties, we can choose according to the market and our own planting costs, and try to choose excellent varieties with fast returns, high yields and good planting to plant.

2. Before planting Polygonatum polygonatum vulgaris, we should build a garden according to the soil environment preferred by Polygonatum polygonatum above, and the soil must be deeply turned, drainage measures should be taken, and foot fertilizer should be applied. In this way, it lays a solid foundation for the growth of Polygonatum polygonatum in the later stage.

3. There are generally two ways of planting Huangjing, seed sowing and rhizome propagation, but we generally choose rhizome propagation, the time of rhizome planting can be spring and autumn, spring is generally in late March, you can plant according to the row spacing of about 30 cm, the plant spacing is about 15 cm, planting is good to water permeable, help germination, the use of such reproduction is relatively fast, the harvest time is short, and the economic benefits are effective.

In terms of variety, Polygonatum polygonatum is planted.

The varieties should be selected for the planting of yellow essence, and the varieties are directly related to the yield, and the later income is also linked.

Polygonatum polygonatum planting technology:1

First, the selection of land preparation.

Choose plots with moist and shady conditions, and the soil should be loam or sandy loam with loose texture and good water retention. Before sowing, the soil is ploughed, raked finely leveled, and furrowed.

2. Planting methods.

1. Rhizome propagation.

In late autumn or early spring around late March, dig up the underground rhizomes, select the young part of the apex, cut into several segments, each section has 3-4 sections, the wound is slightly dried, according to the row spacing of 22-26 cm, the plant spacing is 10-16 cm, 5 cm deep is planted in the neat furrow, covered with soil 3-5 cm, watered after a little suppression, and then watered once every 3-5 days to keep the soil moist. Planted in late autumn, should be covered with some livestock manure or manure after freezing, in order to keep warm for winter, after the second year of thawing, the manure is broken, flattened, and the soil is kept moist before emergence.

2. Seed propagation.

After the seeds are mature in August, the sand storage treatment is carried out immediately: 1 part of the seed, 3 parts of sand are mixed evenly, and placed in a 30 cm deep pit in the shade to keep it moist; In late March of the second year, the seeds are screened out, evenly sown into the shallow ditch of the furrow surface according to the row spacing of 12-15 cm, covered with soil about centimeters, slightly pressed, watered, and covered with a layer of grass. Remove the cover grass before emergence, when the seedling height is 6-9 cm, the seedling can be appropriately spaced in the dense place, and transplanted after 1 year.

In order to meet the growth habit of Polygonatum polygonatum that needs shade, corn can be planted on the ridges.

3. Field management.

In the early stage, it should be cultivated and weeded frequently, and if necessary, the soil can be cultivated in a smooth manner, and the weeds can be pulled in the later stage. If there is a drought or a more sunny and arid place, it is necessary to water in time, and cake fertilizer can be applied when conditions permit, 50-80 kg per mu, and applied in 2 times; After that, 1000-1500 kg per mu of circle fertilizer is applied every year.

Pest Control:

1. Diseases. Black spot is the main disease of Polygonatum polygonatum (Polygonatum polygonatum vulgaris), and the pathogen is a semi-known fungus in the fungus, which harms the leaves. Later, the lesions spread downwards and become more severe during the rainy season. The leaves of the diseased part are yellow. Prevention and control methods:

Clear the garden at harvest time to eliminate the sick and remnant; Before and at the beginning of the disease, spray 1 1 100 times Bordeaux solution or 50% antibacterial special 1000 times solution, once every 7-10 days, several times in a row.

2. Pests. Grub: belongs to the family Coleoptera. With larvae damage, bite off seedlings or chew seedling roots, resulting in broken seedlings or root cavities, serious damage.

Ground tiger: Damage seedlings and rhizomes. Control method: 75% phosphine emulsifiable concentrate can be used to dress seeds according to the amount of seeds; In the field occurrence period, 1000 times of 90% trichlorfon was watered; Trap adults with black lights or poison bait; The application of manure should be fully decomposed, and it is best to use high-temperature compost.

To plant Polygonatum polygonatum polygonatum it is necessary to choose a sandy soil that is loose and breathable and can retain water; The planting time is in March or November, the root nodes of Polygonatum polygonatum are treated and planted in the soil, covered with 2 cm thick fine soil, and can be picked manually after two years of growth; When infested by black spot disease, spray 1000 times diluted Bordeaux liquid for prevention and control.

1. Select the field.

To plant Polygonatum polygonatum you need to choose a cool and humid place, the soil should be loose and breathable, and can retain water, not suitable for air evaporation, you can choose sandy soil; Before planting, the soil should be renovated to allow it to contain more oxygen, and dichlorvos should be sprayed appropriately to eliminate pests in the field.

2. Preparation for planting.

In the planting and management of Polygonatum polygonatum polygonatum Essence, the planting time of Polygonatum Polygonatum polygonatum is in March or November, the mature Polygonatum polygonatum is dug out, the tender parts at the bottom are cut into different segments, each section is about 3 subsections, and the wound is smeared with carbendazim solution to prevent infection, and it can be planted after drying.

3. Planting method.

After the treatment, the polygonatum polygonatum is planted in the field, the spacing between the rows of planting is guaranteed to be about 30 cm, the depth of planting is about 6 cm, and then covered with 2 cm thick fine soil, watering the soil is wet, watering once every three days, always ensure that the growth environment of polygonatum is humid, and the growth cycle of polygonatum is two years.

4. Field management.

During the planting period, weeds will often grow together with Polygonatum to grab the living space, which needs to be treated manually, and the number of weeds is too large, so the diluted dead grass solution can be sprayed; Polygonatum is also susceptible to black spot disease and needs to be sprayed with 1,000 times diluted Bordeaux solution for control.

Polygonatum polygonatum is mostly wild and cold-tolerant plants, and artificial planting needs to imitate the wild environment; However, low temperature is required without frost damage. From late February to early March, the temperature is 10 15, and the germination can grow above 5, but the air temperature is lower than 5 will cause frost damage, and the suitable temperature for general seed germination, root growth and development and top bud germination is 15-20, the emergence is 20, the aboveground plant growth is 16-20, and the underground rhizome growth is 15-20. Generally, areas with abundant heat and large temperature difference between day and night are more conducive to the growth of Polygonatum polygonatum.

Polygonatum polygonatum planting method:

1. Land selection and land preparation: It likes sunlight and has a certain degree of fertility in the soil, so when planting, it is necessary to choose plots with sufficient sunlight and high fertility. First prepare the ground and apply the base. And pay attention to facilitate drainage, it is best to dig ditches around the plot.

2. Sowing method: There are two ways to sow seeds, one is to transplant with tubers, and the other is to use direct sowing. Among them, the transplanting of tubers is carried out in March in the spring, the tubers are divided into subsections, and the wounds are dried and placed for planting, and after planting, they should be covered with thin soil.

Sowing seeds is simpler, and the seeds are planted directly under the soil.

3. Reasonable density: pay attention to the density when planting, usually about 800-100 plants per square meter, depending on the fertility of the soil. The soil is fertile with rows spaced 30 cm apart and plants spaced 20 cm apart.

Poor soils are spaced 20 cm apart in rows and 10 cm apart in each plant, so that the planting will be highly productive.

Planting Polygonatum polygonatum should choose fertile soil, apply base fertilizer after selecting the plot with enough sunlight, prepare the land, and it is best to dig drainage ditches around it to facilitate drainage in the later stage. When sowing, you can use the tuber transplanting method, or you can sow seeds directly. Pay attention to the planting density should be reasonable, usually about 800-100 plants per square meter.

High yields can only be achieved if the density is reasonable. In addition, judging from the current duration, the prospect of planting Polygonatum polygonatum is relatively good and objective.
