Introduction to the propagation method of Spiraea japonica

The cultivation difficulty of hemp leaf embroidery ball is not high, so it is very suitable for ornamental use in the garden. In the full bloom of hemp leaf embroidery ball, its blooming white flowers will cover the branches, very beautiful. Artificial propagation of hemp leaf embroidery ball can be used by sowing, cutting and ramet methods, the editor will briefly introduce to you the breeding method of hemp leaf embroidery ball.

Sowing: can be sowed in spring or autumn. After the seeds were harvested, they were stored in sand for the winter, sowed from March to April in spring, and germinated 30 days later.

Cuttings: the rainy season from June to July. The semi-lignified branches were cut, the length was 8ml 10cm, and 3 leaves were left at the upper end, which were inserted into the sand bed and rooting in 25ml for 30 days, and the dormant branches were cut in the middle and late February.

Ramet: ramet in combination with transplanting in early spring from February to March. Cut the parasite sprouting seedlings of the mother plant, cut them properly, and then plant them separately.

Breeding methods of Spiraea morifolium Reproduction methods of Spiraea

The inflorescence of Spiraea morifolium is dense, the color is white, and it is very beautiful. Spiraea can also be used for cut flower production because of its dazzling color. Then how to raise Spiraea? What are the ways of reproduction? Next, let's get to know it with Xiaoqi.

1. Culture methods of Spiraea

1. Planting: both spring and autumn can be carried out. Generally, it is mainly ornamental by planting on the ground. It should be selected in the place with plenty of sunshine and good ventilation, and the survival rate of dipping holes and dipping pulp is higher. It grows poorly in a shady environment.

2. Light and temperature: it can survive the winter in open field. It grows well under the condition of sufficient light and temperature of 20-25 ℃. Freezing injury and even death will occur when the temperature is lower than-25 ℃ in winter.

3. Watering and fertilization: apply sufficient base fertilizer before planting, generally apply rotten manure, turn tree holes deeply, apply phosphorus and potassium fertilizer (potassium dihydrogen phosphate) 2-3 times at flowering stage, apply overwintering fertilizer at the end of autumn, and stop fertilization in winter to reduce watering a small amount.

4. Plastic surgery and pruning: spring is better. Cut off dry and withered branches, over-dense branches, diseased and weak branches and aged branches before sprouting in early spring, so that the plant looks beautiful, flowers and leaves flourish, and the plant grows vigorously.

5. pest control: when Spiraea is cultivated in the nursery, it has strong resistance, few diseases and insect pests, and no serious diseases have occurred, but after rainstorm, excessive water on the ground and long time of root water accumulation will easily lead to root rot, so it should be drained in time. For diseased plants, 1000 times mancozeb or 800x chlorothalonil can be irrigated and foliage for three times, the symptoms can disappear.

2. Propagation mode of Spiraea chinensis

1. Sowing and reproduction: soak the seeds in warm water (30 ℃) for 1 day and night, take them out and put them in a petri dish covered with moist filter paper. In the room of 18-20 ℃, they begin to germinate in 8-10 days, and the germination ends in about 10 days, with a germination rate of 80% 95%. When the seeds are dry in early summer, they can be sowed immediately after harvest, potted or sown in the open field. Spiraea using mother tree to create moderate shade is beneficial to seed germination and rapid growth at the initial stage of seedlings, and can improve seedling emergence rate and seedling growth rate.

2. Cutting propagation: hardwood cuttings are used in spring and soft wood cuttings are available in summer. Cut 1-2 natural cuttings with branch cuttings, 10-15 cm long, soak in BT rooting powder for 1 day and night, shade with shading net after insertion, and spray to keep the seedbed moist, the survival rate is more than 95%. Spiraea plants are highly sprouting, so they can also be propagated in separate plants, and it is better to propagate in October-December every year.

The above are the breeding methods and breeding methods of Spiraea. Spiraea has strong stress resistance, drought and cold tolerance, no diseases and insect pests, and convenient cultivation and management.

The difference between golden flame Spiraea and hemp leaf Spiraea

Spiraea is as beautiful as snow in early spring and is often made into bouquets and baskets. What's the difference between golden flame Spiraea and hemp leaf Spiraea? What is the effect and effect of Spiraea? Let's learn about it next.

I. the difference between golden flame Spiraea and hemp leaf Spiraea

1. Spiraea: Spiraea is a deciduous shrub with small buds and bud scales of 2-8.

Pods 5, often dehiscing along ventral sutures. Seeds are numerous and small; endosperm quantity may be absent. Its leaf color has rich seasonal changes and has high ornamental value.

2. Spiraea: Spiraea Rosaceae, Spiraea shrubs up to 1.5 meters high; branchlets thin, winter buds small, ovate, leaf rhombus lanceolate to rhombic oblong, dark green above, gray-blue below, both sides glabrous, petiole glabrous. Umbels with many flowers; bracts linear, calyx tube campanulate, sepals triangular or ovate-triangular, petals suborbicular or Obovate, white; disk composed of suborbicular lobes of different sizes, ovary subglabrous, follicles erect opening, style terminal, April-May flowering, July-September fruit.

Second, the efficacy and function of Spiraea.

1. The medicinal effect of Spiraea: Spiraea is a plant that can be used as medicine, its roots, leaves and fruits can be used as medicine, clearing heat and cooling blood and removing blood stasis are all its important effects, which are usually used in the treatment of human injuries.

From a distance, it looks like a beautiful jade belt, giving people a clear and beautiful feeling. It is a good ornamental plant planted on the lawn roadside and by the pool, and it can also absorb some dust. It is very helpful for air purification.

The above is the difference between Spiraea and Spiraea and the efficacy and function of Spiraea. I don't know if you can distinguish between Spiraea and Spiraea. I also want to know other plant knowledge and continue to pay attention to us.
