The cultivation technology of Polygonatum polygonatum and how to plant Polygonatum polygonatum techn

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) Rhizome propagation.

In late autumn or early spring around the end of March, select 1 2-year-old robust, pest-free plant rhizomes, select the apical tender part, 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 the soil with some circle fertilizer and grass to keep warm.

2) Seed propagation.

After the seeds are mature in August, the mature and full seeds are selected and immediately treated with sand storage: 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 the emergence of seedlings, when the seedlings are 6 9 cm high, the seedlings can be appropriately spaced in too dense places, and transplanted after 1 year. 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.

2] 2. 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.

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. [2]

4. Pest control.

Leaf spot. It can be prevented and controlled by 500 times of 65% zeb wettable powder. [3]

Melanoma. It occurs more than spring, summer and autumn, and 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.

Grubs. Take the larvae as the pest, as the root of the damage, bite off the seedling or chew the seedling root, resulting in the broken seedling or root cavity, and the harm is serious. Control method: 75% phosphine emulsifiable concentrate can be used to dress seeds according to the amount of seeds; Or in the field occurrence period, water with 1000 times of 90% trichlorfon. [3]

Second, post-management.

1. Harvesting and processing.

Generally, it is harvested in spring and autumn, harvested in autumn, cultivated for 3 4 years and harvested after the aboveground part withers in the autumn, digs up the rhizome, removes the aboveground parts and fibrous roots, washes off the soil, and steam it in the steamer until it is oily, take it out and dry it or dry it, or boil it in water, and then remove it to dry or dry.

2. Seed retention technology.

Polygonatum polygonatum can be propagated by rhizomes and seeds, but it is better to use rhizomes to propagate in late autumn or early spring, around late March or early spring, select robust and disease-free plants to dig up underground rhizomes and plant them directly.

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.

This cultivation technique is worth learning well, and I think it is very good.

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.

Choose land preparation, because it likes sunlight and likes the soil to have a certain degree of fertility, so when planting, you should choose a plot with sufficient sunlight and high fertility. Prepare the ground first and apply the base. And pay attention to facilitate drainage, it is best to dig ditches around the plot.

Sowing method: There are two ways to sow seeds, one is transplanting with tubers, and the other is using 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, just cover the seeds with soil and plant them.

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.

The planting prospect of Polygonatum polygonatum is relatively good. A few years ago, it was only a few yuan a catty, but now it has generally risen to 20 yuan a catty in the market. In Hunan, the kilogram is about 60 yuan.

The Anhui region even reached 75 yuan per catty. Now the amount of wild yellow essence is relatively small, so it is more objective when planted artificially, so the cultivation technology of ** is worth knowing, so it is helpful for friends who want to make a fortune.
