Sugarcane is suitable for planting in winter. The autumn rainwater accumulated in the soil has not been evaporated in large quantities, and is strongly planted to facilitate the sprouting of sugarcane on hillsides without irrigation conditions. In winter, the ground temperature is higher than the temperature, the roots of winter sugarcane are well developed, and the quality of seedlings is high. , High yield, early maturity, accumulated more sugar.
I. Cultivation techniques
1, selection and preparation
Winter planting sugarcane is planted in low temperature and dry season. In order to keep moisture moist, the selection conditions of planting place are higher than that of spring planting and autumn planting, and lands with irrigation conditions, water accumulation, sunny, flat terrain, and strong water retention ability are selected. It is required that the soil should be finely chopped and flat, with a furrow depth of 30 feet and a row spacing of 90-100 feet. Most of the sugarcane farmers are planted on paddy fields and terraces, and their water retention conditions are good.
2, in due course
The time of winter planting sugarcane is closely related to the safe wintering and sprouting of seedlings and the seedling rate. The planting period is too early. After the sugarcane sprouts, the soil is vulnerable to frost. The unemerged buds are also rotted due to prolonged periods of low temperature and drought. The planting period is too late, and once it is frosted, it is susceptible to freezing and rot. Sugar cane is generally planted from early November to late December or late mid-January.
3, cut down the seed
Since the winter planting sugarcane is under the condition of low temperature and dry season, the quality of the seedlings is required to be high. When cutting the seedlings, it is necessary to choose a robust and disease-free sugarcane plant, and the sugarcane plant generally has 2-3 buds. As the germination time is longer, the general disease is more serious than the spring and autumn cane, and the cut seedlings are best to be disinfected with the lime powder meal incision. When the next kind of deep groove to open up the soil, depth 30-35?, Ditch bottom leveling to ensure the quality of the next species. Winter planting should increase the amount of seedlings, 6500-7500 seedlings per acre, to ensure that the basic seedlings, the next kind of soil should not be too thick.
Second, field management
As the winter planting sugarcane planting period is ahead of schedule and the jointing period is advanced, the measures for field management must focus on the word “early†and must be top-dressed in mid-May. The timely fertilization before the tillering period promotes early delivery and more tillers, and improves the rate of tillering and stem formation. We combine arable and weeding to cultivate soil and apply stem fertilizer in large soil. If the growth rate of sugarcane declines in August and there is a lack of fertilizer, it is necessary to follow the strict tail fertilizer. The winter seedling sugarcane seedlings are the overwintering grounds of the roundworm locusts, so early prevention and control, elimination of the overwintering insects, and prevention of the spread of the insects.
Antiviral:
Antiviral drugs are a class of medication used specifically for treating viral infections. Like antibiotics and broad-spectrum antibiotics for bacteria, most antivirals are used for specific viral infections, while a broad-spectrum antiviral is effective against a wide range of viruses. Unlike most antibiotics, antiviral drugs do not destroy their target pathogen; instead they inhibit their development.
Antiviral drugs are one class of antimicrobials, a larger group which also includes antibiotic (also termed antibacterial), antifungal and antiparasitic drugs, or antiviral drugs based on monoclonal antibodies. Most antivirals are considered relatively harmless to the host, and therefore can be used to treat infections. They should be distinguished from viricides, which are not medication but deactivate or destroy virus particles, either inside or outside the body. Antivirals also can be found in essential oils of some herbs, such as eucalyptus oil and its constituents.Related Products:antiviral drugs,anti-cancer drugs.
Anti-cancer:
Anticancer, or Antineoplastic, drugs are used to treat malignancies, or cancerous growths. Drug therapy may be used alone, or in combination with other treatments such as surgery or radiation therapy.
