Peony is a kind of flower similar to peony, so what is the difference between peony and peony? Let's take a look at it together.

What is the difference between peony and peony?

1. Different leaf shapes

Generally speaking, the biggest difference between peony and peony is the leaf shape. Paeonia lactiflora is a perennial herb with large unbifurcated leaves, while peony is a woody flower with three pointed leaves with many bifurcations, and the peony leaves are green and yellow. there are powdery substances below, and the surface of peony flowers is dark green but very dense.

2. Different designs and colors

4. Different stems

The stem of peony is woody, the stem is stout, and generally will not wither after defoliation, while the stem of peony is herbaceous, almost all wither after defoliation, the stem can be as high as 2 meters, and the peony is mostly about 50cm~80cm, which can be better distinguished.

5. Different florescence

Peony flowers are generally planted in spring, and then florescence is from May to June, which is also the best time to watch peony flowers, while peony flowers bloom in April and fruit in May, which is also the best way to distinguish between the two.

6. Different fruits

Second, what are the common diseases and insect pests of peony?

1. Disease

Leaf spot disease: diseased stems and leaves are the source of infection of the disease. It often occurs in spring and summer, which mainly harms leaves and stems, and petioles also suffer. Methods of prevention and treatment: the diseased stems and leaves were cut off in time, and the fallen leaves were cleaned and burned, and 1 ∶ 1 ∶ Bordeaux solution was sprayed before and after the disease, once every 10 days for several times.

Peony rust: the residual leaves of diseased plants are the source of infection of the disease. It mostly occurs when it is sunny and rainy, warm and humid or low-lying in April-May, which mainly harms the leaves, and the disease is serious from June to August. Prevention and control methods: burn the residual leaves of diseased plants after harvest; select land with high dryness and good drainage for high border planting; at the initial stage of the disease, spray Baomei 0.3-0.4 degree stone sulfur mixture or 97% sodium rust 400 times, once in 7-10 days, many times in a row.

Sclerotinia disease: the soil with sclerotia is the source of infection of the disease. It often causes the disease of stems and leaves in spring. It can occur from seedling stage to adult stage. Prevention and control methods: rotation with cereal crops; in spring, Rain Water do a good job of ditch drainage, reduce humidity, reduce the disease; early detection of diseased plants, dig out with soil, disinfect the disease hole with lime, and spray 1000 times of topiramate around if necessary.

Root rot: the disease remains or seedlings in the soil are the source of infection of the disease. It mainly harms the roots. The disease was serious in the rainy season, and the whole plant withered with the aggravation of the disease. Control method: control of sclerotinia disease.

Peony white silk disease: pathogenic soil and fertilizer are the source of infection of the disease, especially when sweet potatoes and soybeans are used as previous crops, the disease is serious. Mostly before and after flowering, the root and rhizome fell ill in the high temperature and rainy season. Control methods: rotation with Gramineae plants, not with root medicinal plants and crops such as sweet potato, peanut, broad bean, etc.; soak the seed buds with 1000 times of topiramate when planting; dig out and burn the diseased plant with soil, and disinfect the disease hole with lime.

2. Insect pests

Grub: the larva of a copper beetle. It is harmful all the year round and is serious from May to September. Harm to the root, bite into an uneven cavity or broken, causing the aboveground part to grow weak or withered, seriously affecting the yield and quality. Prevention and control methods: remove the injured seedlings and plants in the morning, catch and kill adults by light, pour roots with 50% phoxim EC or 1000-1500 times liquid of trichlorfon, 2 kg carbofuran granules per mu, and mix 20-50 kg of moist fine soil. combined with ploughing and weeding along the ridge.

Small land tiger: also known as "ground silkworm", is a polyphagous underground pest. Generally speaking, the harm is the most serious in spring and autumn, often biting off the seedlings from the ground or biting the ununearthed buds. Prevention and control methods: artificial killing near the affected seedlings before sunrise in the morning; spraying with 98% trichlorfon crystal 1000 times solution or 50% phoxim EC 1000 times solution in the young larva stage Poison bait can be used in the advanced instar stage of larvae, 98% trichlorfon crystals or 50% phoxim EC 100-150 grams per mu are dissolved in 3-5 kg of water, sprayed on 15-20 kg chopped fresh grass or other green manure, spray and mix evenly, spread around the seedlings in the evening, can get a good control effect.

Termites: because of the application of cake fertilizer, it is often easy to attract termites, eat the root bark, hurt the buds, and the leaves turn yellow. Control method: apply cake fertilizer before termites come out of the hole, do not touch the roots; irrigate the roots with new tea cake water or 50% phoxim 200-500 times solution.

Heart drills: most occur in spring, adults lay eggs in the rhizome, after hatching, the larvae drill into the roots, gradually upward decay, light stems and leaves withered and yellow, the heavy ones the whole plant dies. Control methods: find damaged plants, break roots, catch and kill pests; spray more than 1000 times of trichlorfon, or 2.5% trichlorfon powder per mu.
