Peony cultivation

Peony is a fleshy root. Loose, fertile, and deep sandy loam should be selected when planting. If the soil is not good, it needs to be improved. Planting peony to choose high-lying coal. Well-drained areas, should not be planted in the low-lying areas of easy water. Neutral nature of the best soil, planted roots should be properly trimmed before cutting, cut off the roots and broken roots, and then 0.1% of copper sulfate solution or 5% lime water soak for half an hour for disinfection. Then remove and rinse with fresh water. The cutting depth should be the same as that of the soil surface at the junction of rhizomes. In the Yellow River Basin in late August and early October is appropriate. If the planting is too early to cause "fall", there will be no flowers in the following year. If the planting is too late, the wound will heal slowly and survive in the shadow. Even if it survives, the growth will be very thin. It will take only one or two years to recover slowly. Although peony is relatively drought-resistant, watering is also required during the spring and autumn drought seasons, but water cannot be accumulated. When there is a lot of rain in summer, it is also necessary to pay attention to drainage and flood prevention.

Peony is a hibernating plant. In order to make the peony flower colorful and avoid the "flowering every other year" phenomenon, rational fertilization is one of the important conditions. Peony needs to be applied at least 3 times a year. The first time was “flowering before fertilizer”. In the middle and late February, it was applied in combination with pouring “thawing water” and the second time in early May, “post-flowering fertilizer” was applied. If cake fat is used, it must be fully decomposed. For example, compound fertilizer (fertilizer) should be applied far from the main root. 0.2-0.5% potassium dihydrogen phosphate can also be used as a top-dressing fertilizer; the third time before and after the winter Application of fertilizer.
In order to make the peony grow robust and flower colorful, plastic pruning is also very important. 2. The pruning of peonies mainly includes setting, pruning, and removing buds. Lei Lei and other work. After 2-3 years of peony planting, it can be dried. Determine how much the plant keeps branches. The weaker growth. Hairless varieties usually cut thin and weak branches and retain strong skills. It is advisable to keep 3 to 5 dry for varieties with strong growth and many branches. For those species that are particularly strong and grow vigorously, they can be pruned to become a dry type of “peony tree”. The peony should be dried in autumn and winter. Drying depends on the degree of growth of the plant to complete the year, must not be cut and slashed and eager to achieve. There are many adventitious buds in the rhizosphere of peony, which germinate in large quantities every spring and compete with the branches for nutrients and should be promptly removed. In general, animal husbandry Dan Ding after drying, annual degermination and removal of redundant branches, pests and branches, inward branches, cross branches. Parallel branches and overlapping branches can make plants grow well and bloom.

For potted peony, we should select the early and middle flower varieties with strong adaptability and good flower type. The plants should choose to use peony root grafting, two or three years old, and 2-3 branches of small tree peony. If the seedlings are planted with potted plants, the roots of the first plant should be recut, or flattened, or only one or two short branches should be left. When the pots are used, the pots can be smaller. Later, with the growth of the plants, the larger flower pots can be replaced. Basin soil can be used loose, fertile, well-drained, neutral culture soil. In the middle and late September, basins should be planted with appropriate leaves to avoid "falling hair". Pruning and shaping are similar to cultivating peony in the ground. In winter, pay attention to placing potted peony into the “flower pond”. The pool is filled with sawdust to prevent winter overwintering. In the cold area. The peony pots can be buried in the soil, or the above-ground parts of the plants can be wrapped with straw or covered with multi-layer kraft paper bags, and the soil can be used for winter.

Peony is very suitable for promoting the achievement of cultivation. Through the control and adjustment of temperature, it can blossom on New Year's Day, Spring Festival and other festivals. To make it bloom in the Spring Festival, select 4-5 years old varieties, put on the pot 35-60 days before the Spring Festival, and gradually increase the temperature after moving into the greenhouse, and control it at 20-25°C during the day (opening windows for ventilation beyond this limit) , control at 10-15 °C at night, and strengthen leaf spray, ground watering, in order to increase relative humidity. Apply diluted fertilizer once every 7-10 days, and 0.2-0.3% potassium dihydrogen phosphate spray can also be used as top dressing. If the flower buds do not germinate, apply 300-500ppm gibberellin to the scale buds with a brush. Can promote germination. After 40-45 days and up to 60 days (depending on the variety), it can bloom on the eve of the Spring Festival. If flowering is advanced, the pots can be temporarily stored in a low temperature (5-15°C) room.

Reproduction: Peony can be bred, grafted, cut and sowed.

Ramie: It's simple and easy. The Yellow River Basin should be carried out from late September to early October. The entire plant can be excavated in 4-5 years. Remove the soil and leave it in the cool place for 2-3 days until the root becomes soft. In the case of the city's mutual connection, find out where it is easy to separate and open it by hand or open it with a knife. Then plant it.

Grafting: Most roots of peony root are used as rootstocks, and new branches or twigs sprouted on the rhizosphere of large peony plants are selected to be used as scion on short-year annual branches and then grafted by splicing or grafting. Grafting must be completed in late September and early October, otherwise it will affect the survival rate.
Cutting: Less used in the north. The method is: Select the short shoots (brown shoots) sprouted from the rhizosphere of the big plant peony as cuttings, about 15 cm long, treated with hormones. The cutting depth is 1/3 or 1/2 of the length of the scion and it is watered immediately after insertion. The water is sprayed once every 10-15 days, and the bed is often kept moist and shaded. The planting is carried out in September of the following year.

Sowing: Peony seeds have dormancy habits on the epicotyl. After sowing in the fall of the year, the radicles are elongated downward and develop into roots, but no sprouts are unearthed. They must go through a certain period of low temperature (about 1-10 degrees, 60-90 days) to break the dormancy of the hypocotyls, and in the spring Germination unearthed long seedlings. Therefore, the peony seeds are harvested immediately after they ripen in August, and sowed in the same month, so that the second spring is neat and germinating. If the seeds are mature or planted too late, they will not germinate in the spring of the second year, but will need to reach the third year of spring. germination. In order to make Peony seeds germinate neatly in the following spring, wet sand germination can also be carried out after the seeds are mature and harvested. Mix with 2 seeds and 8 parts of wet sand, and then evenly put it in the pot, and then bury the pot in the ground for 0.6 meters, germination for 2 months (2-3 times in the middle), until the seeds give birth to young roots. After the broadcast in mid-October, after sowing, watering and grass protection. Before the winter, pour water once again, so that the spring of the second year will emerge neat and tidy. The seeded seedlings are cultivated for 2 years, transplanted once, and then blossomed again after 3-4 years of cultivation.

Pest control: Peony common diseases include leaf (brown) leaf spot, anthracnose, purple feather disease, and root-knot nematode disease. Insects have longhorned cattle and scale insects.

To control the disease of peony leaf, it can spray equal amount of Bordeaux mixture at the leaves every half month after flowering, spray 7-8 times continuously, or spray 400-500 times sulphur gel suspension once every 7-10 days. Spray 3-4 times. Every year when the winter leaves, cut off the leaves of the peony and burn them together. The disease site of purple feather disease is at the junction of roots or roots. The main methods of prevention and treatment are to disinfect the roots when planting, avoid planting peony in low-humidity areas, and do not use fertilizers that have not been fully decomposed.

The peony root nematode disease occurs near the capillary roots of peony and forms a beaded shape, which causes the peony to grow in a withering state and to die. The prevention and control method is mainly to use chloropicrin for soil disinfection before cultivation. For prevention and control of Tianniu, zinc sulfide can be used. Control locusts, red spiders, available 40% dimethoate or omethoate.
