The planting method of dancing grass

one。 Treatment of seeds:

The seeds of dancing grass can not be sown immediately. You need to remove the wax outside the seed coat first. You can use dry fine sand to do this step. After removing the wax, soak the seeds in warm water of about 38 degrees Celsius for more than a day, then wrap them in a dry cloth and dry them in a cool place. After the seeds are slightly swollen, you can sow them!

two。 Sow:

The thickness of flower seed culture medium is best controlled at about one to three times the diameter of flower seed, if it is too thick, it will increase the burden of seed germination. The suitable temperature for planting dance grass is 20 to 28 degrees Celsius, preferring yin rather than yang. Therefore, it needs to be placed in a cool place without light, and it is best to cover it with a layer of shelter to reduce water evaporation. Remember to open it for 15-20 minutes a day to get some air.

three。 Maintenance after sprouting:

Although the germination time is generally eight to ten days, but do not rush after this time, after all, different temperature, moderation, sunshine and other factors will affect the germination time. After sprouting, you should pay attention to replenishing the light in time, and the sun can help it grow. But try to avoid direct shooting. When two pairs of leaves grow, it means that this dancing grass has been basically fed!

four。 Move the basin:

When the seedlings of the dancing grass grow to nearly an inch, they should be ready to move the basin.

five。 Fertilization and watering:

Fertilization is also very important in the process of planting dancing grass. The time of the first fertilization is about one month after sowing, and the second fertilization is about two to three months. It is best to keep the soil moist all the time during the growth of dancing grass.

How to grow dance grass the planting method of dance grass

Dancing grass in the sun, hand sound wave stimulation will continue to swing up and down, like flying butterflies, but also like a girl on the stage, hence the name. Many people raise this beautiful and interesting plant because of the peculiar characteristics of dance grass. So do you know how to grow dancing grass? What is the planting method of dancing grass? Let's take a look at it with the editor.

Introduction to Dance Grass

Dance grass is an upright shrub, up to 1.5 meters high. Stem simple or branched, glabrous. Leaves Ternate compound, terminal leaflet long elliptic or lanceolate, lateral leaflets very small, long elliptic or linear or sometimes absent. Panicle or raceme terminal or axillary; Corolla purplish red, pistil 10-12 mm long, ovary puberulent. Pods falcate or straight, ventral sutures straight, dorsal sutures slightly constricted, dehiscing along dorsal sutures at maturity, sparsely hooked short hairs, pod nodes 5-9; seeds 4-4.5 mm long and 2.5-3 mm wide. The flowering period is from July to September and the fruiting period is from October to November.

Dancing grass likes the sun, the height of potted plants is about 70-100cm, and the ground planting can reach 1.5-2m. There are three beautiful leaves on the petioles of each branch. When the temperature is above 25 ℃ and the sound is stimulated by 70 decibels, there are a large number of linear leaflets on both sides of the leaves, which are very sensitive to sound waves. When the temperature is not lower than 22 ℃, especially in the sun, they will continuously swing up and down when stimulated by sound waves. It is like a butterfly dancing its wings in flight, and it is also like a young girl with relaxed arms on the stage, hence its name. Born in hills, wilderness and bushes. Like sunshine and drought tolerance, mainly distributed in China, India, Nepal, Bhutan, Sri Lanka.

1. Morphological characteristics

Stem: dancing grass is an erect shrub plant, up to 1.5 meters high. Stem simple or branched, rounded to shaped, minutely striate, glabrous.

Leaves: Ternate leaves, lateral leaflets very small or absent and only simple leaflets; stipules narrow triangular, 10-14 mm long, base 1.7-2.3 mm wide, usually oblique, glabrous, margin sparsely pilose; petiole 1.1-2 cm long, grooved above, sparsely spreading pilose Terminal leaflet long elliptic or lanceolate, 5.5-10 cm long and 1-2.5 cm wide, apex rounded or acute, apiculate, base obtuse or rounded, upper glabrous, below appressed pubescent, lateral veins 8-14 on each side, not reaching leaf margin, lateral leaflets very small, long elliptic or linear or sometimes absent; stipules subulate, 3-5 mm long, both surfaces glabrous; petiolule ca. 2 mm.

Flowers: dancing grass is a panicle or raceme terminal or axillary, inflorescence axis with curved hooked hairs; bracts broadly ovate, ca. 6 mm, dense, deciduous; pedicels 1-4 mm long, extended to 3-7 mm after anthesis, spreading hairs Calyx membranous, 2-2.5 mm long, outer hairy, calyx tube 1-1.5 mm long, upper lobe apex 2-lobed, about 1 mm long, lower lobe about 1 mm long; Corolla purplish red, flag petal 7.5-10 mm long, winged valve 6.5-9.5 mm long, 4-5 mm wide, keel about 10 mm long, 3 mm wide, long stalked, stamens 8-11 mm long Pistil 10-12 mm long, ovary puberulent.

The fruit period of dancing grass is from October to November.

2. Ecological habits

Dancing grass likes the sun and warm and humid environment. Resistant to drought and barren soil. It is a very sensitive plant to sound waves of a certain frequency and intensity, and is also related to temperature and sunlight. When the temperature is above 24 ℃, on a sunny day, the leaflets will cross, kiss and bounce. The two leaves can rotate by up to 180 degrees and then bounce back. When the temperature is 28-34 ℃ or in a muggy sunny day or after rain, throughout the whole pearl, dozens of pairs of leaves sometimes hug like lovers, sometimes dance, dazzling, giving people a fresh and mysterious feeling, when night falls, it sticks the leaves to the branches and snuggles up to each other, which is really a rare flower.

III. Mode of reproduction

Dancing grass can be propagated by sowing. The seedlings emerged about 5 days after sowing, and grew slowly at the seedling stage, so transplanting should bring soil balls.

The method of sowing and reproduction was adopted. First of all, make a seed bed, sow the seeds, drench with water, cover the surface with a thin layer of moist fine soil or fine sand, generally germinate in 5 days, and seedlings can emerge in about 10 days. When the first true leaf appears, the seedlings can be pseudo-planted in a nutrition bowl or planted with 6 leaves. The seedlings are generally planted from October to November and can blossom from January to early April of the following year. When planting, dry, soft and fertile soil should be selected and sufficient organic fertilizer should be applied as base fertilizer.

How to grow dancing grass

First, the planting method of dancing grass

The growth of dancing grass is closely related to various factors in the natural environment. In temperature, light, moisture, culture medium and other factors, due to the great differences in climate in different places, when you sow seeds under natural conditions, please, according to the habits of dancing grass, after carefully studying the local climate of the four seasons, determine the time to sow. If your indoor air conditioning or heating is used to adjust the temperature, the planting will not be affected by the season. the brief introduction of planting techniques is as follows:

1. Seed treatment

The seeds of dancing grass are hard and have a bright waxy appearance, and it takes several months to emerge under natural conditions. Therefore, in order to achieve the purpose of rapid emergence, before sowing, you need to gently rub the wax on the seed appearance with sun-heated or stir-fried dry sand, so that the seed coat is slightly worn out, and then sow the seeds with 38 ℃ of warm water for more than 24 hours (during which the water can be changed several times), and then wrap the seeds in a warm and moisturizing place with coarse cloth, wait for planting to expand, and dry slightly, then sow the seeds (those seeds that are not bubbly should be selected, and then rubbed).

2. When planting

The suitable temperature for sowing is 20-28 ℃. If various growth conditions are not suitable, please do not open the outer package of the seeds and wait for the right time to sow. Dance grass can be preserved for 2 years at a theoretical temperature of 5-10 ℃, but it is recommended to be used as soon as possible under appropriate conditions.

3. Planting

When planting, pay special attention to that the surface of the flower seed can only be covered with a thin layer of culture medium at most, and the thickness is about 1-3 times the diameter of the flower seed, which is as accurate as possible. If the seed is buried too deep, it will become difficult for the seed to sprout. Adjust the spray can to the shape of spray, spray an appropriate amount of water on it, cover the mouth of the flower jar with glass or plastic paper, to reduce moisture evaporation and put the flower pot in the shade without light. Remember to open it for 15-20 minutes every day to breathe. Flowers usually germinate in about 8-10 days. Wait for germination to be patient, sometimes temperature changes and other factors will affect the time of seed germination, please wait patiently.

4. Budding

After the seeds germinate, when the first pair of leaves on the bud spread symmetrically, please remove the covering (glass plate, plastic paper) immediately and place it in the sun to avoid direct sunlight, pay attention to temperature changes, and do not overwater. When the first pair of cotyledons are fully expanded and green, it is necessary to gradually increase the light time in direct sunlight. When the first pair of true leaves grow, they should be placed in direct sunlight throughout the day, pay attention to the dryness of the culture medium, and properly feed water; when the second pair of true leaves grow, it shows that they have passed the most difficult time of planting. As long as you master the temperature, moisture, dancing grass will thrive.

5. Lighting

Lack of light in plants often leads to yellow rust, a disease of plants. The symptom is that yellow spots appear on the leaves and stems, and the grains of diseased plants are not full or overgrown, which makes the plants slender, thin and easy to fall, so the light time should be increased. Turn the flowerpot as often as possible so that the branches and leaves of the plant can receive sunlight from all angles and grow fully.

6. Maintenance

When the seedlings grow to nearly an inch, keep the robust plants and move the rest of the pots. When moving the basin, be careful not to hurt the fibrous root. When removing the seedling, dig a pit of appropriate width and depth in the center of the flowerpot, so that the root system can fully expand, cover the culture medium, gently press, and then pour the right amount of water.

7. Watering

During budding, it is necessary to keep the culture medium moist. After sprouting, it is better to keep dry and dry with the surface culture medium, but the interior is still moist; watering time is as far as possible in the morning, avoid the sun, the water had better be placed for 4-6 minutes, disperse the chlorine in the tap water, it is best to use a thin-eyed kettle when watering, gradually move closer to the plant from the place away from the plant, pour more around, less near the plant, and try not to splash on the leaves and stems.

8. Fertilization

When the plant grows to more than one month, the first fertilization should be carried out, two packets of fertilizer should be provided, the first fertilization should be carried out, and the flowering period of the plant should be carried out, that is, the second fertilization should be carried out when the plant grows to two to three months.

9. Common factors leading to planting failure: (self-detection)

Environmental factors: whether the change of temperature deviates greatly from the suitable temperature for plant germination and growth.

Sowing factors: whether the seed is buried too deep, the seed is not in full contact with the culture medium, and the culture medium is dry during sowing and germination.

Cultivation management factors: forget to use glass panels or plastic covers, as soon as they sprout, they are exposed to the sun, they are watered too little or too much, and after a week of germination, they do not get enough sunshine and forget to apply fertilizer.

A kind of dancing grass grows in India. This kind of dancing grass can be appreciated, and its two curved leaves move endlessly like hands of a clock even when there is no wind. At night, the larger one stops moving, but the smaller leaves are still dancing, which is very lovely. After research, relevant scholars pointed out that the dance of this plant is actually an act of self-defense, in order to drive away the invading animals.

II. Key points of method-level conservation of dancing grass

1. Artificial pollination: the natural pollination rate of dance grass is only 2% Mur5%. If artificial pollination is carried out, the fruit rate can be increased by more than 5 times. Wash your hands during pollination, scrape off the outer surface of the left thumb nail, gently pinch the two keel petals (the middle two petals) with the right thumb and index finger, press the left thumb nail against the top of the keel flap, and gently push back (the keel flap will spread, while the pistil and stamen are in the middle of the keel flap). If the anther is mature, the pollen will spring on the left thumb nail and rub the pollen on the pistil stigma to complete pollination. If the keel flap does not spread during pollination, it means that the anther is not mature and the pollination time should be postponed.

2. Annual sowing: the conventional seedling raising of dancing grass is usually sown from May to August, and the annual sowing can greatly accelerate the propagation speed. Those planted in the open field can be sown in spring, summer and autumn, as well as indoors in winter. Generally speaking, the plants sown before the end of May can blossom and bear fruit in the same year, the flowering period is 9-October and the fruiting period is 9-11; those sown after the end of July can blossom and bear fruit in the first half of the following year, but the seeds can be obtained one quarter earlier than those sown and raised seedlings.

3. Seed germination: there is a waxy layer on the seed surface, which makes it difficult to soak; the seed surface contains substances that inhibit its own germination, which is difficult to germinate after sowing. The germination rate can be greatly increased by accelerating the germination of seeds. Soak the seeds in warm water of 40 degrees, change the water once a day, and rub the seeds many times in the soaking process to remove the surface wax and the substances that inhibit germination. After soaking the seeds for several days, when the seeds are white, the seeds can be sown, and the germination rate is more than 95%.

4. Cutting propagation: cutting propagation can be carried out in spring, summer and autumn, and can also be carried out indoors or in greenhouse in winter. Cut the sturdy branches of the year as cuttings, cut them into 5 cm long into a section (leaving a leaf at the top and a branch at the base), insert them into a fine sand basin, insert them with a depth of 2 cm 3 for the length of the ear, and pour water after the insertion. Insert the basin in a cool and ventilated place, cover the glass plate and often spray water to moisturize. It can take root after 10 days, and after a few days, go to cover and stop squatting seedlings for 3 days, and then it can be planted in the basin.

5. Lighting: the plants of dancing grass are lack of light, and the phenomenon of overgrowth often occurs, which makes the plants slender, thin and easy to invert, so the lighting time should be increased. Turn the flowerpot as often as possible so that the branches and leaves of the plant can receive sunlight from all angles and grow fully.

6. Temperature: the cold resistance of lover grass plant is strong. Under the condition of natural temperature in Kunming winter, some varieties can survive the winter in the open field. As long as the roots of most varieties have fully grown before the beginning of winter, even if all the aboveground leaves are withered, its persistent roots will sprout and blossom in the coming spring. However, the flowering of lovegrass is very sensitive to low temperature. The flower branches can grow and blossom only when the daytime temperature is more than 20 ℃ and the night temperature is not lower than 10 ℃. Otherwise, even the flowering branches that have been drawn can not blossom or bloom unsatisfactorily at low temperature, or even turn yellow and die. Lover grass that blossoms in autumn and winter should do a good job of heat preservation.

7. Watering: it is necessary to keep the culture medium moist during budding. After sprouting, keep a little dry, dry with the surface culture medium, but the interior is still moist; watering time as far as possible in the morning, avoid the sun, the water had better be placed for 6 minutes to disperse the chlorine in the tap water, it is best to use a thin-eyed kettle when watering, gradually move closer to the plant from far away from the plant, pour more around, less near the plant, and try not to splash on the leaves and stems.

8. Fertilization: the first fertilization should be carried out when the plant grows for more than a month. Plant flowering period: that is, when the plant grows to 2-3 months, the second fertilization is carried out.

III. Disease control of dancing grass

There are few insect pests in dancing grass, but there are more diseases, especially in vegetable stubble and so on. The main diseases are powdery mildew, anthracnose, leaf spot, root rot and blight. When the disease occurs, the diseased leaves should be cut off and burned in time. Spraying 50% carbendazim wettable powder 500 times or topirazine wettable powder 500 times, once every 10-14 days, spraying 3Mel 4 times can be cured; in addition, Bordeaux solution (1Rutl 100) or Bordeaux and Bordeaux solution alternately sprayed 3MU 4 times, the effect on leaf spot is better. The 500-fold solution of Dysen zinc is better for the control of blight. Continuous cropping for many years is beneficial to the spread of the disease, so the stubble should be changed every 4-5 years. The main pests are ground tiger, powder medium, thrips, mites, armyworm and so on.

The function and use of dancing grass

1. Ornamental value

Dancing grass leaves have the characteristics of natural dance, have been used in horticulture and ornamental industry, is an excellent material for making bonsai, high ornamental value, can be cultivated, and is a famous interesting ornamental plant.

2. The value of scientific research

Dance grass is the only plant in nature that can respond to sound. According to scientific research, the reason for grass dancing is mainly related to temperature, sunlight and the induction of sound waves under certain rhythm, rhythm and intensity.

In the environment of strong light at room temperature and no wind and rain, the two side leaflets of dancing grass will keep swinging. Within half a minute, each leaf can complete an oval movement, and after each leaf rotates up to 180 degrees, it bounces back to its original place, and then dances again.

Even in the midnight "sleep" state, the lobules are still turning slowly, but at a slower speed than during the day. Whenever night falls, the dancing grass goes into a "sleep" state, with the petiole pressed upward to the branch and the top lobule drooping, just like a closed pocketknife. With the arrival of the morning light, the angle of its leaf axils increases and the parietal lobule is stretched out.

If you lift its terminal lobule up after the grass enters its "sleep", you will find that it still maintains a certain state of tension when it is drooping. The angle of leaf axil and the angle of parietal lobule and petiole are difficult to change at will. Its petiole is raised and the apical leaflet is pressed down because a group of cells in the petiole of the parietal leaflet and the petiole of the whole compound leaf increase the turgor pressure; in the normal state during the day, the turgor pressure is increased by a group of cells in the opposite position of the petiole.

Why does dancing grass have this kind of "catatonic sleep"? We know that when plants carry out photosynthesis during the day, the leaves take a position perpendicular to the direction of gravity and a consistent drooping posture, which reduces energy consumption. This is also a way of adaptation formed by plants in the process of long-term evolution.

Dance grass can dance to music, dance grass "dance", not the whole plant in the movement, the so-called dance that arouses people's interest is that a pair of lateral lobules can obviously rotate: or do a 360-degree loop, or swing up and down. Although the leaflets on the same plant move fast and slow, they are quite rhythmic. Sometimes the two leaflets close up at the same time, and then slowly spread apart, like butterflies dancing their wings; sometimes one is up, the other is down, like the graceful dance of rhythmic gymnastics; sometimes many lobules dance at the same time, rising and falling one after another, a spectacle.

The stronger the light or the greater the vibration of sound waves, the faster the movement will be until all the leaves droop and close to sleep at night. Whenever the sun goes down, when night falls, the light becomes weaker and different from the daytime light, the sponge shrinks and the leaves hang down and stick to the branches.

The reason why the lateral leaflets of the dancing grass keep dancing is due to the fact that the cavernous tissue at the base of the petiolule is sensitive to light. Whenever the sun shines and the temperature rises, the water in the plant evaporates quickly, the sponge expands and the lobules swing from side to side. In addition, the dance grass will also have a sense of sound, and when it is oscillated by a song with a volume of 35-40 decibels, the sponge will also contract, driving the small leaves to dance.

Studies have shown that when the external temperature reaches more than 20C, the lateral leaflets of dance grass begin to rotate. When the temperature rises above 30 degrees C, it rotates most actively and speeds up a lot.

The rotation of the lateral leaflets of dancing grass is neither caused by external stimulation like mimosa, nor is it as phototaxis as sunflower. This kind of movement is indeed rare in the plant kingdom. So why does the dancing grass dance? It is still a mystery and remains to be further studied and explored.

Cultivation techniques of Dance Grass

Taking good care of the seeds is the first step in growing dance grass. The seeds of dancing grass are very strong, and their appearance is as bright as a layer of wax, and it takes 2 months to grow seedlings without external interference. So, in order for the seedlings to grow quickly, rub the surface of the seeds with overheated sand before sowing. After the skin of the seeds is worn out and the appearance is no longer bright, soak the seeds in 40 ℃ of hot water for more than a day, then wrap the seeds in a warm, wet place like a baby, wait until the seeds become slightly bigger, dry to about half, and then sow the seeds!

After reading this article, you must all know why dancing grass likes dancing. I hope the article edited will make you happy.
