The Propagation method of Watermelon Piper Grass

Watermelon peel pepper prairie is produced in Brazil, its cold tolerance is poor, when the winter temperature is lower than 13 ℃, it will suffer frost damage. Artificial cultivation of watermelon pepper grass is not difficult, reproduction can use ramet and cutting methods, the editor will briefly introduce to you the two propagation methods of watermelon pepper grass.

Watermelon peel pepper grass

I. split-plant propagation

Can be carried out in the spring and autumn, select the plant with new buds at the root of the mother plant, combined with turning the basin to change the soil to take out the plant, shake off the attached soil, and use a sharp knife to cut the new bud potted plant according to the position of the new bud. When ramet, pay attention to protect the root system of the mother plant and the new bud. It can also be poured out and divided into several pots when the plant is full of pots.

Second, cutting propagation: cutting has branches and leaves.

1. Branch insertion can be carried out in spring and summer, select strong branches, cut 5-8 cm scions, remove the lower leaves, dry the cut, and then insert them into the wet sand bed. It can take root at a temperature of 18-25 ℃ in semi-shade.

2. Leaf cuttings are mostly carried out from May to October. When inserting leaves, choose strong and full leaves, take off all the full leaves with petioles, take petioles of 2mi 3cm, dry for 2 to 3 hours after the wound is slightly dry, and insert them obliquely into the sand bed or basin at an angle of 35 ~ 45 degrees between the petiole and the seedbed, and the matrix uses washed river sand with 20% vermiculite of 30% vermiculite. Keep it moist, put it in half-shade, 20: 25 ℃, about 4: 5 weeks can produce adventitious roots and buds, and about 2 months can grow into seedlings. When the seedling grows to 4ml / 5cm, it will be transplanted into the pot. But avoid the medium too wet, to avoid cuttings rot. Avoid covering with plastic film or glass when cutting, otherwise it is perishable.

How to raise watermelon pepper grass culture method of watermelon pepper grass

Watermelon pepper prairie is native to South America and tropical regions, with regular silver-white color bands between leaves, similar to watermelon markings, is a perennial herb, evergreen all the year round, flowering from March to May. Many people do not know how to raise watermelon pepper grass, the following editor will introduce to you the cultivation methods and cultivation techniques of watermelon pepper grass and other related knowledge.

Introduction of watermelon peel pepper grass

Watermelon pepper grass, also known as bean green pepper grass, is a perennial herb, evergreen all the year round, watermelon pepper prairie produces South America and tropical regions. The stem is short and tufted, and the petiole is reddish brown. The leaves of Capsicum sativum L. are oval, pointed at the end of the tail, and about 6cm. Leaf veins radiate from the center to all sides, 8 main veins, dark green, silver gray between veins, shaped like watermelon peel, hence the name watermelon peel pepper grass.

1. Morphological characteristics

Plant: Zanthoxylum bungeanum is a clustered plant with tufted watermelon peel-shaped leaves on the short stem. The height of the plant is about 15-20 cm.

Leaves: the leaves of Zanthoxylum bungeanum are ovate, long 3~5cm and wide 2~4cm. Petiole reddish brown, long 10~15cm. Leaf veins radiate from the center to all sides; 11 main veins, dark green, silver-gray between veins, like watermelon peel. Stems short, with dark red petioles. The leaves are dense, fleshy, peltate or broadly ovate, 2-5 cm long, green on the surface and red on the back. The veins of the leaves are green, with regular silver-white bands between the leaves, similar to the markings of watermelons.

Flowers: the watermelon pepper grass is a spike with small, white flowers. The flowering period of watermelon and pepper grass is from March to May.

2. Ecological habits

The optimum temperature for the growth of watermelon prickly ash was 20-28 ℃, and the growth was slow when it was more than 30 ℃ and less than 15 ℃.

The cold tolerance of watermelon pepper grass is poor, and the lowest indoor temperature should not be lower than 10 ℃ in winter, otherwise it is vulnerable to freezing injury.

III. Mode of reproduction

1. Ramet propagation

Can be carried out in the spring and autumn, select the plant with new buds at the root of the mother plant, combined with turning the basin to change the soil to take out the plant, shake off the attached soil, and use a sharp knife to cut the new bud potted plant according to the position of the new bud. When ramet, pay attention to protect the root system of the mother plant and the new bud. It can also be poured out and divided into several pots when the plant is full of pots. Cutting propagation can be divided into branches and leaves.

Branch insertion can be carried out in spring and summer, select strong branches, cut 5cm to 8cm scion, remove the lower leaves, dry the cut, and then insert it into the wet sand bed. It can take root at a temperature of 18-25 ℃ in semi-shade.

2. Leaf cutting propagation

Most of them are carried out from May to October. When inserting leaves, choose strong and full leaves, take off all the full leaves with petioles, take petioles of 2-3 cm, dry for 2-3 hours, wait for the wound to dry slightly, and insert them obliquely in the sand bed or basin, the angle between petiole and seedling bed is 35 ~ 45 degrees, and the matrix is mixed with washed river sand with 20% vermiculite. Keep it moist, put it in half-shade, 20: 25 ℃, about 4: 5 weeks can produce adventitious roots and buds, and about 2 months can grow into seedlings. When the seedling grows to 4-5 cm, it is transplanted into the basin. But avoid the medium too wet, to avoid cuttings rot. Avoid covering with plastic film or glass when cutting, otherwise it is perishable.

Cultivation techniques of watermelon and pepper grass

Watermelon pepper grass likes the environment of high temperature, humidity, semi-shade and high air humidity. In order to maintain the beautiful markings of the leaves, the following must be done:

1. Substrate: it needs to be cultivated in loose, fertile and well-drained soil, but grows poorly in clay. The basin soil should be mixed with coarse sand or cinder ash. It can also be cultivated with peat soil and perlite.

2. Temperature: watermelon pepper grass is neither resistant to severe cold nor heat. The optimum temperature for growth is 20: 30 ℃. When the air temperature is more than 30 ℃ and less than 15 ℃, the growth becomes slow. The lowest temperature in winter can not be lower than 10 ℃, otherwise it is vulnerable to freezing injury. There are even physiological diseases.

3. Soil: the basin soil is mainly composed of rotten leaf soil and mixed with a small amount of river sand.

Illumination: because the watermelon skin pepper grass is more shady, it should be placed in the indoor bright scattered light place, do not have strong light directly. Spring and autumn should be moved to a well-ventilated and slightly sunny place for maintenance. Like semi-overcast or scattered light, can only be maintained in the whole sun in winter, shade 50% in summer, otherwise it is easy to burn leaves. But too shady, the leaves are dim, grayish green, and the markings are not obvious.

Moisture: it is necessary to keep the basin soil moist during the growing season, but there can be no stagnant water in the basin, otherwise the roots and leaves will rot easily, and even the whole plant will die. In summer and dry season, water should be sprayed on the leaf surface 2 or 3 times a day to increase air humidity and promote the formation of leaf markings. Fear of both drought and waterlogging, drought will wilt, yellow, or even death; waterlogging will produce root rot. The basin soil can be kept slightly moist, and it can also be watered when the basin soil surface is dry. In winter, if the temperature is slightly lower, watering should be controlled to make the basin soil dry and wet alternately.

Fertilizer: usually need to apply thin pancake fertilizer or compound fertilizer once a month, nitrogen fertilizer should not be too much, such as lack of phosphate fertilizer, it is easy to cause leaf markings to disappear and reduce the ornamental effect. To apply balanced fertilizer, do not apply nitrogen fertilizer alone, otherwise the stripes of "watermelon" will not be obvious and the ornamental value will be greatly reduced. It is best to use thin liquid fertilizer to irrigate basin soil, too thick fertilizer is easy to cause plant necrosis.

Humidity: need high air humidity, not resistant to drying, in addition to normal watering, but also often spray water to the plant, if there are conditions, it is best to sprinkle water to humidify the growth environment, the effect is good. The growth of leaves is extremely abnormal in a dry environment.

Culture method of watermelon peel pepper grass

1. Potted soil

The pot cultivation of watermelon and pepper grass should be mainly composed of rotten leaf soil and a small amount of river sand.

2. Display environment

Usually can be placed in the indoor bright scattered light place to cultivate, do not have strong light direct.

3. Fertilizing and watering

Apply thin rotten cake fertilizer and water once a month. If there is too much fertilization, especially too much nitrogen fertilizer and lack of phosphate fertilizer, it is easy to cause leaf markings to disappear and reduce the ornamental value. Keep the basin soil moist during the growing season, but there can be no stagnant water in the basin, otherwise the roots and leaves will rot easily, and even the whole plant will die. Apply thin pancake fertilizer and water or all-element chemical fertilizer once a month.

4. Matrix preparation

With loose, drained and ventilated imported peat of 5-40mm specification, break the peat and mix well with water. (standard of adding water: after mixing well with water, hold a handful of peat tightly and the water oozes from the fingers) to be planted in a cup. The peat consumption in each basin of the 9cm basin is about 250ml, and a packet of 300L imported peat can hold about 1200 cups.

5. Upper basin

Requirements for potting seedlings: select high-quality seedlings produced professionally, with a height of 5-8 inches, leaves of 6-10 pieces, no diseases and insect pests, no withered leaves and yellow leaves.

For the old basin that is re-used, it must be soaked in potassium permanganate 1000 times solution for more than half an hour, then rinse with clean water and dry for use. The new basin can be used directly. Generally, first use a smaller flowerpot (9cm plastic pot) to plant, first cushion the appropriate substrate at the bottom of the cup, and then move the sieve seedlings into the cup, the seedlings can be appropriately planted deeper, with the base of the flat plant slightly above, 1 ball / pot; the matrix is loose and tight moderately, loaded to the cup 9 minutes full, gently vibrate the basin soil, and pour the roots semi-thoroughly or with surface water.

6. Cultivation characteristics

Watermelon peel pepper grass likes the environment of high temperature, moist, semi-shade and high air humidity. Not only is not resistant to cold, but also avoid extreme heat. Pot containers should choose tile pots or coarse sand pots with rough texture and strong water permeability, and potted plants should choose rotten leaf soil as the main culture soil, which can be mixed with rotten leaf soil, garden soil and river sand. When the seedlings are in the pot, pay attention to protect the roots, water the plants once and put them in a ventilated shade for about a week, then they can be managed normally. Usually should be placed in a semi-shady place to cultivate, do not bright light direct. Like enough scattered light.

Too strong light is disadvantageous to growth, overcast is easy to produce overgrowth, and lose beautiful markings, reduce the ornamental effect. Branches and leaves are nearly fleshy and have the function of storing water, so they have a certain ability to resist drought. Avoid watering too much, and if the basin soil is too wet, it will cause the rotten roots of the plants to die. During the growing season, the basin soil should be kept moist, but there should be no water in the basin, otherwise the roots and leaves will rot easily, or even the whole plant will die. it is better to irrigate or spray the plant with lukewarm calcium-free soft water, and the cold water will cause the plant to rot. After the beginning of winter, it is more necessary to control the amount of water, and the water temperature should not be lower than room temperature. Apply thin rotten cake fertilizer and water once a month, avoid applying thick fertilizer, and avoid contaminating the leaves. If there is too much fertilization, especially too much nitrogen fertilizer and lack of phosphate fertilizer, it is easy to cause leaf markings to disappear and reduce the ornamental value. 0.1%-0.2% urea can also be used as extra-root topdressing.

7. Humidity requirements

The requirement of air humidity is higher, so it is appropriate to spray water on the leaf surface once or twice a day in summer and dry season, and sprinkle water on the ground around the flowerpot in order to maintain high air humidity and promote the formation of leaf markings. In spring and autumn, it is best to move to a place with good outdoor ventilation and a little sunshine, and then move or indoor for a period of time, so that the plant can grow healthily. The pot should be changed once every two years, because the old plant can not maintain a strong ornamental effect, so it should be renewed frequently. When the ventilation is poor, it is easy to be harmed by shell insects. It should be timely removed or sprayed with 1000 times of omethoate EC for prevention and control. When the soil is too wet or even stagnant, it is easy to cause root rot, so it should be drained or changed in time to improve the soil quality.

Disease control of watermelon peel pepper grass

1. Disease control

The diseases of watermelon peel pepper grass are less, and the diseases are common in leaf spot, which can be controlled by spraying carbendazim, Dianlituo and so on.

2. Pest control

The main pests of watermelon pepper grass are red spiders and shell insects, which can be sprayed with special insecticides, such as triclofenac, Nisolan to control red spiders, parathion and chlorpyrifos to control shell insects. Attention should be paid to the disinfection of cultivation places, pots and pots and soil. Root rot and scab are harmful, and spraying Bordeaux solution can control the spread of the disease.

Garden use of watermelon peel pepper grass

Watermelon pepper grass plant shape is short, luxuriant growth, whether as a pot decoration, or hanging appreciation are very suitable. The leaves of watermelon pepper grass are striped like watermelons. It is suitable for pot cutting or hanging cultivation.

The green leaves of watermelon and pepper grass are thick, bright and green, and they are evergreen all the year round. They are common small foliage plants. Suitable for potted plants and hanging baskets, often used for interior decoration.

Propagation methods of watermelon pepper grass what are the matters needing attention in the propagation of watermelon pepper grass

When it comes to watermelon pepper grass, I believe we are no stranger to it, watermelon pepper grass is a kind of plant with ramet propagation and cutting propagation as the main way of reproduction. Many flower friends have also had their own experience of raising watermelon and pepper grass. So, do you know the key points and matters needing attention in the reproduction of watermelon and pepper grass? Let's study with the editor.

Common ramet and cuttage propagation:

Ramet propagation

Can be carried out in the spring and autumn, select the plant with new buds at the root of the mother plant, combined with turning the basin to change the soil to take out the plant, shake off the attached soil, and use a sharp knife to cut the new bud potted plant according to the position of the new bud. When ramet, pay attention to protect the root system of the mother plant and the new bud. It can also be poured out and divided into several pots when the plant is full of pots.

Cutting propagation: cutting and branch cutting and leaf cutting.

(1) Branch insertion can be carried out in spring and summer, select strong branches, cut 5-8 cm scions, remove the lower leaves, dry the cut, and then insert them into the wet sand bed. It can take root at a temperature of 18-25 ℃ in semi-shade.

(2) Leaf cuttings are mostly carried out from May to October. When inserting leaves, choose strong and full leaves, take off all the full leaves with petioles, take petioles of 2-3 cm, dry for 2-3 hours, wait for the wound to dry slightly, and insert them obliquely in the sand bed or basin, the angle between petiole and seedling bed is 35 ~ 45 degrees, and the matrix is mixed with washed river sand with 20% vermiculite. Keep it moist, put it in half-shade, 20: 25 ℃, about 4: 5 weeks can produce adventitious roots and buds, and about 2 months can grow into seedlings. When the seedling grows to 4-5 cm, it is transplanted into the basin. But avoid the medium too wet, to avoid cuttings rot. Avoid covering with plastic film or glass when cutting, otherwise it is perishable.
