Peony how to plant flowers and plants to teach you the correct maintenance method

Peony is a very ornamental horticultural plant, and its flowers are large and gorgeous, giving people a sense of infinite vitality after they are in full bloom, so they are very suitable for planting in gardens and courtyards. The cultivation of peony has certain requirements on the environment, so we must pay more attention to the cultivation. So what are the specific planting and maintenance methods of peony? After reading this article, go and plant some plants to try.

Paeonia lactiflora is planted by seedling cultivation. First of all, the soil must be selected. Only when the base soil is selected correctly can the peony seedlings have nutrients for growth. The soil needed by Paeonia lactiflora is rich and soft humus soil or sandy soil, both of which are nutritious and permeable. Pour the selected soil into a flowerpot of about 50 centimeters, and pay attention to spreading a few pieces of rubble or sprinkling some broken stones at the bottom of the flowerpot before dumping the soil, which is conducive to the smooth discharge of stagnant water out of the flowerpot.

Secondly, the seedlings of Paeonia lactiflora should be selected. The seedlings should have more branches and branches with certain hardness. This type of seedlings can adapt to the environment more quickly and survive more easily after planting.

We should pay attention to whether the leaves of the seedlings are flat and green, but if the leaves are soft and have a tendency to wither, it is not suitable to plant, because the rate of nutrient absorption of this kind of seedlings is too slow and the survival rate is low. Planted peony seedlings should pay attention to timely replenishment of water, generally once every two weeks, each watering amount should not be too much, too much will lead to soil moisture and corrosion of the roots of peony.

Paeonia lactiflora is a plant that likes fertilizer and light very much, so we must ensure adequate fertilizer and light. You can keep peony in the habit of applying compound fertilizer once a month and put it on the balcony to receive sunlight in sunny weather, so that it can fully synthesize the nutrients needed for growth. If you plant peony directly in the courtyard, you should pay attention to the rainstorm weather.

Propagation methods of Paeonia lactiflora

Propagation methods of Paeonia lactiflora: 1. Plant division method

The method of plant division is the most commonly used propagation method of Paeonia lactiflora, which is basically used in the production of seedlings in peony producing areas. It has three advantages: first, it blossoms earlier than sowing method, sowing seedlings blossom in 4 ~ 5 years, and ramet seedlings can blossom every other year; second, ramet operation is simple and easy to operate, labor-saving management is conducive to wide application; third, it can maintain the excellent characters of the original varieties. The disadvantage is that the reproduction coefficient is low, and the three-year-old mother plant can only be divided into 3-5 offspring, so it is difficult to adapt to and meet the needs of modern large-scale production and the rapid growth of domestic and foreign flower markets. This has always been a difficult problem perplexing the production of peony seedlings.

Propagation methods of Paeonia lactiflora: 2. Sowing method

Seeds should be sowed immediately after harvest. With the delay of sowing time, the water content of seeds decreased and the germination rate decreased. The seed has the characteristics of double dormancy of Hypocotyl and Hypocotyl. After sowing, the soil temperature in autumn makes the Hypocotyl of the seed release dormancy and the radicle develops and takes root. The better the rooting in the current year, the more vigorous the growth in the coming year; if the sowing is too late, the ground temperature can not release the Hypocotyl dormancy, and the germination rate will be greatly reduced in the following spring. After sowing and rooting in autumn, the dormancy of Hypocotyl can be relieved after a long period of low temperature in winter. The following spring, when the temperature rises and the humidity is suitable, the germ will be unearthed.

Propagation methods of Paeonia lactiflora: 3. Cutting method

Select a high-lying, well-drained nursery as a cutting bed, after the bed soil is loosened, spread 15 cm thick river sand, and the river sand should be disinfected with 0.5% potassium permanganate. The cutting substrate can also be vermiculite or perlite. Build a 1.5-meter-high sunshade on the bed. According to the experience of Changchun and other places, the effect of cutting cuttings in mid-July is the best. The cuttings are 10-15 cm long. With two nodes, the last compound leaf, leaving a little leaf; the next compound leaf, even petiole cut off, with a concentration of 500 × 10 ~ 1000 × 10 naphthalene acetic acid or indole acetic acid solution quickly dipped in cuttings, cutting depth of about 5 cm, the spacing between leaves do not overlap each other. Pour water after insertion, and then cover the plastic shed. It is observed that the rooting effect is the best when the substrate temperature is 2830 ℃ and the humidity is 50%. If the temperature is 20: 25 ℃ and the humidity is 80% 90% in the cutting shed, it can take root and form dormant buds 20-30 days after cutting. After taking root, the amount of water spraying and watering should be reduced, and the plastic shed and sunshade should be removed gradually. The cuttings grow slowly and need to be covered with soil on the bed to survive the winter, and then moved to the open field for planting the following spring.

Propagation methods of Paeonia lactiflora: 4. Root insertion method

The roots of Paeonia lactiflora were cut off in autumn and cut into 5-10 cm root segments, which were inserted into deep-turned and flat ditches with a depth of 10-15 cm, covered with fine soil 5-10 cm thick, and watered thoroughly.

Propagation methods of Paeonia lactiflora: 5. Striping method

In spring, the young buds unearthed soon after they are unearthed will pass through the pots of the flowerpots and be introduced into the flowerpots with a diameter of 15cm to 20cm. They will gradually fill the soil with growth, keep the potted soil moist, take root in summer, and cut off the stems under the pots before winter to form a potted peony.

Propagation methods of Paeonia lactiflora: 6. Modern tissue culture method

Plant tissue culture, that is, plant aseptic culture technology, is based on the theory that plant cells are totipotent, using isolated organs, tissues or cells of Paeonia lactiflora (such as roots, stems, leaves, etc.). Callus, adventitious buds and adventitious roots were induced under the conditions of aseptic and suitable artificial medium, light and temperature, and finally formed a complete plant with the same heredity as the mother. This technology, also known as cloning technology, achieves the purpose of rapid propagation and has the value of wide application.

There are six main propagation methods of peony, of which the plant division method is the most commonly used, which can keep the variety excellent and relatively simple. If you want to propagate the peony in the furniture, this method is better.

The planting method of Paeonia lactiflora _ how to grow Peony

Paeonia lactiflora, alias general and grass, is a famous herbaceous flower of the genus Paeonia in the peony family. How should this kind of flower be planted in daily life? The following is the planting method of Paeonia lactiflora that we have sorted out. I hope it will be helpful to everyone!

Planting methods of Paeonia lactiflora

one. Seed harvesting

When the follicles turn yellow, they can be harvested, the seeds are not hot prematurely, and the seed coat blackens and hardens at a later time. Fruit ripening sooner or later, should be harvested in batches, pericarp cracking scattered seeds, you can sow, do not expose the seeds, so that the seed coat hardened, affecting seedling emergence. If the seeds can not be sowed in time, it is feasible to store sand to keep moisture, but the seeds must be taken out and sown before the seeds take root.

two. Sowing time

Paeonia lactiflora must be sown in time in the same year, such as sowing in late August to late September in Heze area, if it is later than late September, it will not be able to take root in that year, and the germination rate will be greatly reduced in the next spring; moreover, even if seedlings emerge, because the roots of seedlings are not developed, it is difficult to resist the drought in spring and is easy to die. Therefore, Heze several spring sowing experiments, all failed.

three. Sowing method

Seed treatment: before sowing, remove the shrunken seeds and impurities from the seeds to be sown, and then remove the unsubstantial seeds by water selection. Although the seed coat of Paeonia lactiflora is thinner than that of peony, it is easier to absorb water and germinate, but if the seed is treated before sowing, it will germinate more neatly, and the germination rate will be greatly improved, often reaching more than 80%. The method is to soak the seeds in 50 ℃ warm water for 24 hours and sow them immediately after being taken out.

Whole bed sowing: the sowing and seedling land should be fully fertilized, and if the soil is moist and suitable for sowing, you can do border sowing directly; if the soil moisture is poor, you should fully irrigate, and then do border sowing. The width of the border is about 50 cm, the distance between the borders is 30 cm, and the seeds are sown according to row spacing of 6 cm and seed spacing of 3 cm. If the seeds are sufficient, the seed spacing is not less than 3 cm, and the seed spacing is not less than 3 cm. After sowing, it is covered with wet soil with a thickness of about 2 cm. Every 666. 7 square meters with seed about 50 kg, sowing about 100 kg. Cover with plastic film after sowing and remove it after sprouting and unearthing in the following spring. It is also feasible for strip sowing, strip spacing 40 cm, grain spacing 3 cm, covering soil 5 cm, or row hole sowing, hole spacing 20 cm, 5 seeds per hole, and soil pile 10 cm 20 cm after sowing, in order to prevent cold and preserve moisture. Rake it flat before sprouting in the following spring.

Planting management of Paeonia lactiflora

one. Land use requirement

The planting land is selected with high dryness and good drainage, which requires deep, loose and fertile sandy urban soil. When planting in saline-alkali areas, it is necessary to change the soil; when planting in lower areas, to build a high platform, there should be sufficient clean water sources for irrigation. Avoid continuous cropping of peony. Field cultivation generally rotates once every 3 to 4 years, otherwise the growth will be weakened and the damage of diseases and insect pests will be serious. When cropping cannot be rotated on time due to land limitations, deep turning should be carried out 1-2 months before planting. The depth is 60cm to 100cm, each 666. 7 square meters can be applied 1500-2000 kg of rotten dried manure or 200-250 kg of cake fertilizer, remember not to apply raw fertilizer that is not mature.

two. Suitable planting period

No matter sowing seedlings or ramet seedlings were planted from late August (the End of Heat) to late September (the Autumn Equinox) in Heze and from late September (the Autumn Equinox) to early November (the Beginning of Winter) in Yangzhou. It is usually carried out in combination with ramet.

three. Planting specification

The row spacing of ornamental cultivation plants in the garden can be 1 m × 1 m, and the planting points can be arranged in "product shape", so that the land can be used uniformly and reasonably, which is beneficial to the symmetrical growth of plants, but the field operation is sometimes inconvenient for field management and observation and recording. the horizontal and vertical "square" arrangement is often used. The specification of the planting hole, the depth is about 35cm, the diameter of the upper mouth is 18cm, the digging pit should be narrow at the top and wide at the bottom, the thick root should not be removed during ornamental cultivation and propagation, and the root-promoting seedling after rooting is used in medicinal cultivation (Zhejiang Dongyang method), the hole is naked about 25 cm. If you directly use the peony root after planting, the depth can also be shallow.

Propagation methods of Paeonia lactiflora

one. The cutting method selects the nursery with high topography and good drainage as the cutting bed. After the bed soil is loosened, 15 cm thick river sand is spread, and the river sand should be used 0. 5% potassium permanganate disinfection. The cutting substrate can also be vermiculite or perlite. Build a height of 1 on the bed. In the 5-meter awning, according to the experience of Changchun and other places, the effect of cutting cuttings in mid-July is the best. The cuttings are 10-15 cm long. With two nodes, the last compound leaf, leaving a little leaf; the next compound leaf, even petiole cut off, with a concentration of 500 × 10 ~ 1000 × 10 naphthalene acetic acid or indole acetic acid solution quickly dipped in cuttings, cutting depth of about 5 cm, the spacing between leaves do not overlap each other. Pour water after insertion, and then cover the plastic shed. It is observed that the rooting effect is the best when the substrate temperature is 2830 ℃ and the humidity is 50%. If the temperature is 20: 25 ℃ and the humidity is 80% 90% in the cutting shed, it can take root and form dormant buds 20-30 days after cutting. After taking root, the amount of water spraying and watering should be reduced, and the plastic shed and sunshade should be removed gradually. The cuttings grow slowly and need to be covered with soil on the bed to survive the winter, and then moved to the open field for planting the following spring.

two. In the root insertion method, the root was cut into a root segment of 5 cm and 10 cm in autumn, which was inserted into a deep turned and leveled ditch with a depth of 10 cm, covered with fine soil 5 cm and 10 cm thick, and watered thoroughly.

three. Striping method in spring will sprout unearthed buds, through the pot hole of the flowerpot, introduced into the diameter of 15-20 cm flowerpot, gradually fill the soil with growth, keep the pot soil moist, can take root in summer, cut off the stem under the pot before winter, to form a potted peony.

four. Modern tissue culture method plant tissue culture, that is, plant aseptic culture technology, is based on the theory that plant cells have totipotency, using isolated organs, tissues or cells of Paeonia lactiflora (such as roots, stems, leaves, etc.). Under the conditions of aseptic and suitable artificial medium, light and temperature, callus, adventitious buds and adventitious roots were induced, and finally a complete plant with the same heredity as the mother was formed. This technology, also known as cloning technology, achieves the purpose of rapid propagation and has the value of wide application.

Disease and pest control of peony planting

1. Beetles

Species and damage of pests: there are many kinds of beetles that harm peony, such as county black velvet Gill beetle, apple beautiful beetle, yellow hairy Gill beetle, its adults harm peony leaves and flowers, larva grub, insect body nearly cylindrical, bent into "C" shape, milky white, head yellowish brown, 3 pairs of chest feet, no abdominal feet. The wound caused by feeding on the root of peony creates conditions for the infection of Fusarium and leads to the occurrence of root rot.

two. Shell worm

(1) pests and damage: scale insects are also known as scale. There are several kinds of shell insects that harm peony, such as cotton blowing scale, Japanese wax scale, long white shield scale, mulberry white shield scale, peony round scale, sagittal shield scale and so on.

The shell insects suck the bodily fluids of peony, weakening the plant growth and yellowing branches and leaves.

(2) Prevention and control methods

① should strengthen quarantine and strictly prevent the introduction of insect-carrying seedlings

② protects and utilizes natural enemies.

③ grasps the egg during the incubation period, and the newly hatched worm surface is not covered with wax and is easy to be killed. It can spray 40% omethoate 1000 times, or 50% malathion emulsion 800 times 1000 times, or 50% phoxim emulsion 1000 times. Spray evenly and spray the whole plant. The spray is ineffective after the wax shell is formed.

④ irrigated the rhizosphere with furan solution, the plant absorbed the fungicide, and the worm was poisoned after sucking plant body fluid.

When ⑤ finds that individual branches are damaged by scale insects, it can be brushed off with a soft brush, or cut off insect pests and burned.

three. Aphids

The main results are as follows: (1) the harm of peony is often caused by aphids. When peony sprouts in spring, aphids fly to harm, suck the juice of leaves and make the affected leaves curl and turn yellow. after the seedlings grow up, aphids often gather in tender shoots, pedicels, leaf backs and other places, so that the stems and leaves of flower seedlings curl and shrink, so that the whole plant withered and died.

(2) occurrence regularity: under the condition of high temperature and drying, aphids reproduce quickly and do serious harm. Aphids can reproduce for several generations a year or even twenty or thirty generations. Aphids secrete honey, which can hinder the physiological activities of stems and leaves of the injured plants; at the same time, honey is a good medium for bacteria, which often causes coal fouling disease; aphids can also spread virus diseases.

(3) Prevention and control methods.

① removes overwintering weeds.

② protects and utilizes its natural enemies. The main natural enemies are Coccinella axyridis, Coccinella septempunctata, Coccinella maculata, Coccinella tortoise, aphid flies and lacewings.

③ sprayed 40% dimethoate emulsion 1000-1500 times, or 80% dichlorvos 1500-2000 times, or 50% aphid pine emulsion 1000-1500 times.
