Every time the sun rises and sets, the light source is weakened, which is different from the light source in broad daylight. The penis sponge will fold, and the leaves will hang down, close tightly and stick to the branches. The fundamental reason for the continuous fan dance of grass-side leaflets is the conclusion that the mechanism of penis cavernosum at the bottom of its petiole is sensitive to light. Whenever the sun shines directly and the temperature rises, the water in the green plant evaporates faster, the cavernous body of the penis expands and the leaflets swing from side to side.
In addition, the dancing grass will continue to have the feeling of sound. When it suffers from 35~40 sound bombs, the corpus cavernosum will also gather to push the small leaves to dance. The results showed that when the outside temperature exceeded 20C, the lateral leaflets of grass gradually rotated. When the temperature rises above 30 degrees Celsius, its rotation becomes active and much faster.
Seed treatment Because the dancing grass has the characteristics of hard seeds and bright surface wax, it usually takes several months to germinate. Therefore, in order to make it germinate quickly, before sowing, it is necessary to gently rub a layer of fruit wax with sun-dried or parched fine sand to achieve the practical effect of slightly breaking the seed coat, then soak it in warm water at 38℃ for more than one day, then take down the seeds, wrap them in old coarse cloth, put them in a warm, moist and hydrating place, and sow them after they swell and slightly dry. The suitable sowing temperature of dancing grass is about 20-28℃.
When sowing, pay attention to cover the surface of the flower seeds with a thin layer of molding material, which is about 1-3 times of the pore size of the flower seeds. If the seeds are buried too deep, it will make the germination period difficult. Sprinkle water with a sprayer as appropriate, and it is best to cover the mouth of the flowerpot with adhesive tape to reduce water evaporation. Keep the flowerpot in a cool place to avoid light, but pay attention to open it every day 15-20min for ventilation. Flower seeds usually germinate in about 8- 10 days. But sometimes it is likely to be disturbed by factors such as temperature changes, and the normal germination time of seeds will change to a certain extent, so don't worry too much.
Pay attention to the symmetry of the first pair of tender leaves on the bud. You must remove the mulch immediately and then move it to Chaoyang District. However, it is necessary to prevent direct sunlight and pay attention to temperature changes. Too much irrigation is not advisable. When the first pair of young leaves are emerald green, it is necessary to gradually increase the illumination time in the sun.
When the first pair of leaves appear, it should be irradiated for 24 hours while keeping the molding material slightly wet. When the second pair of leaves came out, it showed that the sowing had been basically successful. As long as the temperature and water management methods are paid attention to, the dancing grass can grow healthily.
