The dancing grass is sunny, with small shrubs. The potted plants are about 70-100 cm high, and the ground plants can reach 1.5-2 m. There are 3 delicate leaves on each petiole. When the temperature reaches 25 °C and above, the sound is stimulated at 70 decibels. Next, the two small leaves around the middle of the big leaf will "play on their own", the name "dance grass", giving people fresh and mysterious. Born in the hills and bushes, it is a rare plant that is on the verge of extinction. It is sunny and drought-tolerant, mainly distributed in China, India, Nepal, Bhutan and Sri Lanka.
Living habits: hi sunshine and warm and humid environment. Drought-tolerant, resistant to thin soil, often growing in hilly hillsides or ravine shrubs, or growing in mountains at an altitude of 2,000 meters.
Illumination: The lack of light in the dancing grass plants often leads to the phenomenon of lengthening, making the plants slender, thin and easy to fall, and should increase the illumination time. Rotate the pot as often as possible so that the foliage of the plant receives sunlight from all angles and is fully grown.
Temperature: The cold resistance of lover grass plants is strong. Under the natural temperature conditions in Kunming in winter, there are varieties that can be exposed to winter. Most of the varieties are fully grown as long as the roots are frozen before winter. Even if all the above ground leaves are dead, their roots are in the coming year. Spring will also sprout. However, the flowering of lovers grass is extremely sensitive to low temperature reaction. Only when the daytime temperature reaches 20°C or above, and the nighttime temperature is not lower than 10°C, the flowering branches can grow and bloom. Otherwise, the flowering branches that have been extracted cannot bloom or bloom under low temperature, and even Yellow and dead. The lover's grass that blooms in autumn and winter should be specially insulated.
Watering: During the budding, it is necessary to keep the culture medium moist. After budding, it should be kept dry, and the surface culture medium should be dry, and the inside should be wet. The watering time should be as far as possible in the morning, avoiding the sunlight. The water should be placed for 4-6 minutes first, and the chlorine in the tap water should be dispersed. When using water, it is best to use a fine-eyed pot. From the place far away from the plant, gradually move closer to the plant, and pour some more around it. There are fewer plants nearby, and try not to splash on the leaves and stems.
Fertilization: When the plant grows for more than a month, the first fertilization is required. Plant flowering period: when the plant grows to 2~3 months, the second fertilization is carried out.
Pest control: There are few grass pests, but there are many diseases, especially when it is planted in vegetable rafts. The main diseases are powdery mildew, anthracnose, leaf spot, root rot and disease. In the onset of disease, it is necessary to cut off and burn the diseased leaves in time. Spray 50% carbendazim wettable powder 500 times solution or thiophanate WP 500 times solution, spray once every 10-14 days, spray 3-4 times to cure; in addition to Bordeaux mixture (1:1 : 100) or the combination of the antibacterial and Bordeaux mixture spray 3-4 times, the effect on leaf spot is better. Daisen zinc 500 times liquid is better for the prevention and control of disease. Years of continuous cropping is conducive to the spread of disease, so it should be replaced once every 4-5 years. Pests mainly include tigers, powders, thrips, mites, armyworms, etc., and the corresponding drugs can be used for prevention and treatment.
Artificial pollination: The natural pollination rate of dancing grass is only 2%-5%. If artificial pollination is carried out, the result rate can be increased by more than 5 times. Wash your hands during pollination, scrape the outer surface of the left thumb, and use the right thumb and index finger to gently squeeze the two keel flaps (two petals in the middle). The left thumb is placed against the top of the keel and pushed back ( The keel flap will spread out, while the pistil and stamen are in the middle of the keel. If the anther is mature, it will bounce outward. The pollen will be bucked on the left thumb and the pollen will be applied to the pistil head to complete the pollination. If the keel flap does not spread when pollinating, it indicates that the anther is not mature and the pollination time must be postponed.
Anniversary sowing: Conventional seedlings for dancing grass are usually planted in May-August, and the use of annual seeding can greatly speed up the breeding. Planted in open field can be planted in spring, summer and autumn, and can be planted indoors in winter. Generally, the plants planted before the end of May can be flowered in the same year. The flowering period is 9–10 months, and the fruiting period is 9–11 months. After the end of July, the first half of the year can be flowered, but it can be earlier than the conventional seeding. Get the seed.
Seed germination: There is a layer of wax on the surface of the dancing grass seeds, and it is difficult to infiltrate the water; the surface layer of the seed contains substances that inhibit self-germination, and it is difficult to germinate after sowing. The germination rate can be greatly improved by germination of seeds. The germination time is soaked with warm water of 40 degrees, and the water is changed once a day. During the soaking process, the seeds are sprayed several times to remove the surface wax and the surface layer to inhibit the germination. After soaking for several days, when the seeds are white, they can be sown, and the germination rate is over 95%.
Airway bills courier form refer to documents used by the express industry to record the sender, recipient, product weight, price and other related information during the delivery of goods. At present, the express delivery industry mostly uses bar code express orders to ensure continuous data output in the express delivery industry and facilitate management.
At present, the paper used for express delivery forms is generally multi-part carbonless Copy Paper, etc. The processing technology mainly uses continuous code printing, skipping code variable code printing, and most of them are more than 3 copies, especially for EMS, etc. express orders are mostly 5 copies.
In 6 pairs, it can be divided into ordinary barcode slips and adhesive-backed barcode slips. The ordinary barcode slips need to be used with courier bags. The last page of the adhesive-backed barcode slip can be torn off and pasted on the goods, which is more convenient to use. The regular size is 217*127,230 *140,230*127,240*150, etc.
The most advanced system currently used in the express waybill production industry is the Kodak Wanyin coding system, which has the advantages of high processing efficiency, high precision and high stability.
