There are some propagation methods of lotus.

Lotus

Lotus is a kind of herbaceous flower plant growing in water, with large and fat neck and roots, beautiful leaves like a girl's skirt, and flowers attract eyeballs whether they are open or not. In the 1980s, the lotus was named as one of the top ten famous flowers in China, its fruit is edible, flowers and leaves can be used for ornamental, is a very valuable plant. How to breed lotus has become a topic discussed by many novice flower friends, so the following focuses on the breeding methods and management points of lotus.

First, the growth environment of lotus

Lotus is an aquatic plant, which is suitable for calm shallow water, lakes, marshes and ponds with relatively stable sex. The water requirement of lotus depends on its varieties. Large plant-shaped varieties such as ancient lotus and red thousand-leaf are relatively deep, but not more than 1.7 meters. Small and medium-sized plants are only suitable for a water depth of 20-60 cm. At the same time, the lotus is very sensitive to water loss. As long as it is not irrigated for 3 hours in summer, the lotus leaves planted in the water tank will languish. If the water stops for one day, the lotus leaves will scorch and the buds will wither. Lotus is also very fond of light, and full light is needed during the growth period. The lotus is extremely intolerant to shade and will show a strong phototaxis when it grows in the semi-shade.

Second, the propagation methods of lotus

1. Seed propagation

The first thing is to break the shell. From May to June, the concave end of the seed was worn out on the cement ground or on rough stones, and the seeds were soaked to raise seedlings. To keep the water clear, change the water frequently, sprout in about a week, take root and transplant two weeks later, one plant in each pot, the water layer should be shallow, do not drown the lotus leaves in the water. About 90% can blossom in that year, but not many in that year.

two。 Split lotus root propagation

The best time to turn potted lotus root is from mid-March to mid-April. Planting prematurely will have the influence of cold current, and planting lotus root is easy to suffer frost damage. The northern area can be covered with transparent agricultural film in case of cold snap. Before planting, the basin mud should be mixed into a paste. When planting, the top of the lotus root is inserted at an oblique angle of 20 degrees along the edge of the basin, and the bowl lotus is about 5 cm deep. The large lotus is about 10 cm deep, with a low head and a high tail. The tail is half warped to keep the end of the lotus root from getting into the water. After planting, put the pot in the sun to make the surface soil crack, so that the lotus root is completely bonded with the soil, then add a small amount of water, wait for the bud to grow, gradually deepen the water level, and finally maintain the water layer of 3-5 cm. In the early stage of pond planting, the water layer is the same as the basin lotus, and in the later stage, the lotus leaves are not submerged.

III. Management after propagation of lotus

1. Water and fertilizer management

Lotus is an aquatic plant, which can not be separated from water all the time during the growing period. In the early stage of growth, the water layer should be controlled at about three centimeters, and the depth of water is not conducive to the improvement of soil temperature. If tap water is used, it is best to put it in another tank and use it in the sun for one or two days. Summer is the peak period for the growth of lotus, so there must be no shortage of water in the basin. After the beginning of winter, the basin soil should also be kept moist to prevent lotus root from drying up due to lack of water. The fertilizer of lotus is mainly phosphorus and potassium fertilizer, supplemented by nitrogen fertilizer. If the soil is more fertile, there is no need to apply fertilizer throughout the year. Rotten cake fertilizer and chicken, duck and goose manure are the most ideal fertilizers. Half a pair of fertilizer can be applied in a small basin, while only 1: 2 taels can be applied in a large basin. No more fertilizer should be applied, and should be fully mixed with the soil. During the peak growth period, if you find that the leaves are yellow and thin, you can mix them in the mud with 0.5 grams of urea per box and rub them into small balls of about 10 grams. One grain is applied in each basin and it is effective in the soil in the center of the basin for 7 days.

two。 Overwintering management

After the beginning of winter, the basin can be put indoors or buried under the permafrost. The north of the Yellow River should not only be buried under the permafrost but also covered with agricultural film to keep the basin soil moist throughout the winter.

If the lotus is raised only for ornamental purposes, then it can be allowed to reproduce freely, but if you want to improve the ornamental value or want to breed lotus roots for sale, you have to strictly follow the above methods.

Breeding methods of Liriodendron chinense Reproduction methods of Liriodendron chinense

The whole plant of stone lotus is fleshy and pulpy, with short stems and 10-shaped branches. Today, I'm going to share with you the methods of breeding and breeding of Liriodendron chinensis.

Culture methods of Liriodendron chinense:

1. Soil

The basin soil is required to be loose and fertile and has good drainage and air permeability. rotten leaf soil or peat soil, coarse sand or vermiculite can be used in half, mixed with a small amount of bone powder and other calcareous materials. Because the soil is moist, the newly planted plants do not need to irrigate too much water to maintain their semi-dry state to facilitate the restoration of roots.

two。 Temperature

Liriodendron prefers warm, humid and semi-overcast growth environment, the optimum growth temperature is 20-30 ℃, and the overwintering temperature is 15 ℃. In winter, when the temperature is not lower than 5 ℃ at night and above 15 ℃ during the day, the plant can continue to grow and can be watered normally and fertilized properly, and if watering is controlled to make the plant dormant, it can also tolerate the low temperature of 0 ℃. The long-growing grass is not heat-resistant, and the plant growth stops gradually after May. When it enters the summer dormancy period, the family can keep it under the corridor or on the inside of the balcony where there is no direct sunlight, good ventilation and no rain, and control watering and stop fertilizing, so as to avoid plant rot caused by muggy, damp and stagnant soil.

3. Light

Stone lotus is dormant in high temperature in summer and cold in winter. the main growth period is in the cooler spring and autumn seasons, and sufficient sunlight is required in the growth period. if insufficient light will lead to loose plant shape, not compact, affecting its ornamental, while the plants growing in the place of sufficient light, the leaves are thick and full, the plant shape is compact and the leaf color is beautiful.

4. Watering

Watering master do not dry, irrigate thoroughly, avoid long-term stagnant water, so as not to cause rotten roots, but not too dry, otherwise the plant will not die, but the growth is slow, the leaf color is dull, lack of vitality. In the period of high temperature in summer, the leaf water evaporation is large and the water demand is more, such as the lack of water is very easy to make the leaf wilt, so it is necessary to spray water to the leaf surface frequently and keep the environment moist at the same time, but the stagnant water in the basin must be avoided, otherwise it will cause root rot.

5. Winter maintenance

In the low-temperature winter, the roots of Elaeagnus angustifolia are easy to rot and become rootless plants. High temperature in midsummer, it is not appropriate to water more, but less water spray, do not shower. Fertilize once a month during the growing period to keep the leaves green. However, excessive fertilization will also lead to excessive growth of stems and leaves. In the growing season, flowerpots should be placed in a ventilated and transparent place, and the room temperature should be kept warm in winter. The room temperature is about 10 ℃, and sufficient light should be given. The plants of more than 2-3 years old tend to be aging, so new seedlings should be cultivated and renewed in time.

The method of propagation of Liriodendron chinense:

1. Ramet

It is best to do it in spring and cuttage propagation is commonly used. Indoor cuttage can be carried out in four seasons, especially from August to October, with fast rooting and high survival rate. Cuttings can be cut with single leaves, tillers or apical branches, and the length of the cuttings is unlimited, but the cut should be dried and then inserted into the sand bed. It usually takes about 20 days to take root after insertion.

2. Leaf cutting

Lay the complete mature leaves on the moist sandy soil, with the leaves facing up and back down, without covering the soil and placing them in a cool place. Leaflets and new roots can grow from the base of the leaves in about 10 days, and the roots can be buried in the soil. In the future, let it bask in the sun, properly water and fertilize, and it will gradually grow into a strong new plant.

3. Cuttings

Single leaf, tiller branch or top branch can be used, and the cutting length is unlimited, but after the cut is dry, remove the lower leaves and insert them into the sand bed. It usually takes about 20 days to take root after insertion. Insert the soil should not be too wet, otherwise the cut is easy to yellow rot, the root length of 2-3 cm on the basin. Leaf cuttings can also be used.

Culture method of anemone the propagation method of anemone

Anemone is often born in lakes, ponds and rivers. In summer and autumn, small white flowers bloom. Seen from a distance, they are very pastoral. Today, we are going to tell and share the knowledge of the culture method of anemone and the breeding method of anemone.

Culture method of anemone

The row spacing of cultivated anemone varies according to the ornamental requirements, generally around 60cm, in the initial shallow water, and then gradually deepen the water level according to the growth of the plant. Generally planted in the pool, water depth of about 40 cm is more appropriate, pot water depth of about 10 cm.

Potted anemone is generally based on ordinary pond mud, and the substrate should not be too fat, otherwise the branches and leaves will be luxuriant and the flowering will be rare. Keep plenty of sunshine at ordinary times, and there should be no shortage of water in the basin, otherwise the anemone will easily dry up.

In order to promote the growth and development of the anemone plant and improve its ornamental effect, weeds and debris should be removed in time during the growing period of the anemone plant, keep the water clean, and apply fertilizer 1-2 times combined with weeding.

Keep water in the basin in winter, and you can survive the winter by putting it in a leeward and sunny place. The winter temperature in northern China is relatively low, so overwintering treatment should be carried out when cultivating anemone. The main pest of anemone is aphids, and the control effect can be achieved by spraying 40% dimethoate emulsion 1000 times.

In addition, potted anemones are generally divided into pots every 2-3 years.

Propagation methods of anemone

Anemone can be propagated by seeds and individual plants. Seed propagation of anemone means that the seeds of anemone are soaked in warm water of 22-25 ℃ to promote germination and propagation. The propagation of anemone is mainly based on the pseudophytic phenomenon at the end of the petiole.
