Therapeutic heating pads usually operate from household current and must have protection against overheating.
A moist Heating Pad is used dry on the user's skin. These pads register temperatures from 76 to 82 °C (169 to 180 °F) and are intended for deep tissue treatment and can be dangerous if left on unattended. Moist Heating Pads are used mainly by physical therapists but can be found for home use. A moist cloth can be added with a stupe cover to add more moisture to the treatment.

1. Choosing good varieties is the key to high yield. The white bitter gourd and green bitter gourd 915 developed by the Chinese Academy of Agricultural Sciences are favored by vegetable farmers because of their good quality, high yield, and strong disease resistance. Before sowing, the seeds were soaked in hot water of 55°C and agitated. When the temperature was lowered to 30°C, soaking for 12 hours (if the seeds were gently opened, the seeds would absorb water, and the soaking time was 8 hours). Subsequently, the seeds were washed and removed, wrapped in clean gauze, and germinated in a thermostat at about 30°C. Wash it once daily with lukewarm water and begin budding approximately 4-5 days later. In this way, it can kill the germs brought by the seeds, and it can ensure the buds.
2, sowing bitter gourd open cultivation, generally in the greenhouse in the first nursery. The prepared soil is prepared the day before sowing (eclogous peat grass with no melons grown: vermiculite: rotted manure drier=1:1:1:0.5; diammonium phosphate plus 1 kg/m3, After sieving and dosing, piling up into piles, covering with plastic sheeting, using it after a few days, mixing evenly once during use, loading in a 10 cm X10 cm nutrient bowl, or installing in a prepared nursery pot (with wood) Bars shall be made into squares by 10 cm X 10 cm, and the middle of the squares shall be hit with a wooden stick with a 1 cm deep eye). The next day after spraying the nutrient soil with water, a thin layer of fine soil can be sowed. Put the seeds of the buds in the little eyes (Note: The buds are down on the soil). Cover the seeds with a small mound of about 1.5 centimeters thick, and then sprinkle a layer of fine soil. Taking the Beijing area as an example, planting is generally conducted at the end of March and the beginning of April. The seedling age is about 30-35 days. After the final frost in early May, the planting field will be planted. Cultivating strong seedlings is one of the elements of producing pollution-free vegetables.
3. Seedling management After sowing, the greenhouse must be sealed to raise the temperature. The seedlings should be inserted into a small shed, covered with a film, and warmed and moisturized to keep the temperature at 30-35°C during the day and 15°C during the night. When 50% of the seedlings emerged, cover the membrane of the small shed in time. After the seedlings are released, the indoor temperature is maintained at 20-25°C during the day and at about 10°C during the night. See dry watering, take the principle of temperature control without water control, keep the seedlings grow robustly. Afterwards, the temperature in the shed was gradually reduced, and the shed film was opened a few days before the planting to carry out the hardening.
4, colonization due to bitter gourd thermophilic and fat-resistant crops, it is necessary to give enough base fertilizer. Apply 5,000 kg of high-quality organic fertilizer and 30 kg of ammonium phosphate per 667 square meters. After mixing, press 1.5 meters to make water. After a few days, dry the soil and make it 80-90 cm wide. , 10-15 cm high sorghum, 5-7 days before planting on the mulch. Every two rows, 60 cm spacing, planting line. Digging pits should not be too deep. It is advisable to block some water after planting. In order to prevent the ground temperature from declining, the dredging method is generally adopted. After the water in the pit is infiltrated, the pit is sealed with soil to prevent air leakage. After the planting, it must be inserted in a timely manner. Because the bitter gourd grows very strong, it is necessary to insert a firm frame. The distance between racks is 20 cm (a slightly thicker rack can be 30 cm). Timely plugging can also improve the microclimate in the field, which will help the seedlings quickly grow seedlings. Planting 1300-1600 strains per 667 square meters, using 250-300 grams of seed.
5, field management in time after the seedlings slowly pouring water, so the temperature is still at the end of the water can not be too large. A few days later, the cultivars will be intensively cultivated in order to preserve the soil temperature and promote plant growth and development. Due to the strong branching ability of the plant, select 2-3 thick vines from the lower part, tie the vines to the shelves, and destroy the rest. During this period, water is generally not available. When the first melons all sit and start to inflate, water and follow the water to recover 10-15 kg of urea or 20-25 kg/667 m2 of ammonium bicarbonate. Therefore, when the plants enter the growing season, they should be top-dressed according to weather changes, plant growth, and soil conditions. This is called "seeing the sky, watching the land, and looking at the crops." It should be noted that because the bitter gourd roots are more developed, the plant growth potential is stronger, watering should not be overworked, so as to avoid causing light and long pods not to produce melon, poor ventilation and light transmission cause disease or overwhelm the frame, resulting in economic losses. About 40-50 days after colonization, commercial melons are harvested. The melon period needs more fertilizer.
6. Diseases and Insect Pest Control Due to less disease resistance of bitter gourd, leaf mold and powdery mildew generally occur in the late growth stage. Usually 50% thiophanate-methyl WP 1000 times or 10% triadimefon EC 1500 times spray. 20% omethoate 1000 times spray to control aphids, Krypton 1500-2000 times spray to control red spider, camellia.
Momordica charantia is a short-day plant. It is hi-temperature, hi light, heat-resistance, moisture-resistance, and immeasurable to shade. The requirements for light length are not strict. Longer-time light is beneficial to its good growth, and it requires higher soil moisture and air humidity. However, it is not tolerant; it has wide adaptability and can be cultivated in various soils in the north and south of China. In recent years, vegetable growers in some areas are also growing in greenhouses or greenhouses.
