Wanyan No.1 small winter melon is made up of the mother-in-law Wanhe 09-214 and the father-in-law pillow 09-312. The plant has strong growth potential and branching, medium and early maturity, short cylindrical shape, beautiful appearance and dark skin color. Green wax-free powder, high commodity rate, firm flesh and minimal cavity. The number of melons per plant is more than 4, the yield per plant is 3~4kg, and the average yield of 667m2 is 2800kg. It is resistant to blight and is extremely resistant to storage and transportation. China's north and south open fields or greenhouses are suitable for planting.
1. Seeding and seedlings. Soak the seeds with warm water at 50-55 °C (continuously stirring to normal temperature) and then soak the seeds for 7-9 hours; pick up the soaked seeds and spread them to cool the surface of the seeds; use moist (60-70% water content) The sand cloth or towel is wrapped in a sealed bag; the treated seeds are placed in a 31-32 ° C incubator for germination, and the sealed bag is ventilated once every 2 to 3 hours, and the small melon seeds can be exposed for about two days. Can be sown, so the seed germination rate is about 90%. The seedlings can be raised by seedling cups or nursery beds, and one spot is placed in each hole, and the substrate is covered with 1 to 2 cm after sowing. After the seeds are emerged, maintain proper temperature and humidity during the day to cultivate strong seedlings. When the seedlings reach 2 leaves and 1 heart, they can be colonized.
2. Colonization. Apply the base fertilizer before planting, apply organic fertilizer 200kg/667m2, superphosphate 50kg/667m2, then deep turn, fine, flattening, creping, wide 1.8m ditch, double row planting, plant spacing 80cm, Line spacing is 100cm, and the shape of the plant is planted. Generally, the planting is about 800 to 1000 plants per mu. When the seedling reaches 2 leaves and 1 heart, it is the most suitable planting period. It is selected to be planted in sunny afternoon, and the root water is poured in time.
3. Fertilizer management. In the case of pouring enough root water, the melon seedlings enter the slow seedling period, and generally do not need watering during the slow seedling period, as long as the soil is kept moist, when the melon seedlings grow 5 to 6 true leaves, per acre Twenty-three compound fertilizer 25 ~ 30kg, urea 7 ~ 10kg, superphosphate 15 ~ 20kg, promote the extension of vines, increase plant nutrient accumulation, which is conducive to the formation of female flowers and sitting melon; after the female flowers are open, control the fertilizer to control the water to prevent the growth of the melon; When the fruit grows to 0.3-0.5kg, it is necessary to strengthen the management of fertilizer and water, and promote fruit expansion. Apply 3-5 yuan of compound fertilizer per acre to potassium chloride for 5~10kg, once every time, once every 2~3 times.
4. Racking and pruning. It is cultivated in the form of a flat frame with bamboo. The height of the flat frame is about 2 meters and the width is about 3.6 meters. Each seedling is a bamboo. When the melon is started, the melon seedlings are placed on the bamboo to let it sit on the shelf. The whole process is carried out by a single vine whole plant method, that is, all side vines should be removed before and after the shelf. During the cultivation process, the topping treatment can be appropriately carried out, that is, when the melon seedling grows to half of the flat frame or the flat frame, the topping is performed once, and then one side bud is left to grow, which is beneficial to increase the fruit setting rate and the commodity rate.
5. Artificial pollination and fruit selection. In order to increase the fruit setting rate, artificial pollination can be carried out every day from 8:00 to 9:00 in the flowering period. Remove the male flower that is open that day, and gently wipe it on the stigma of the female flower. One male flower can apply 2 to 3 female flowers. In general, the melons are kept from the second female flower, and the melons that can be knotted in each section are mainly preserved and harvested until the melons are harvested.
6. Pest control. The main diseases of the small melon are blight, disease, etc.; the main pests are thrips, whiteflies and so on. In the early stage of wilt disease, 800-fold solution of wilting spirit or 120-200 times of phytoremediation or 400 times solution of chlorosis can be used for prevention and control of root disease; the disease should be controlled after heavy rain or heavy rain, and 58% of Rydmir 800 times can be used. , 800 times of plague cream or 1000 times of anti-virus sputum spray; scorpion horse, whitefly can be sprayed with 2.5% sputum 2500 ~ 3000 times liquid, good winter 1000 times liquid or 蓟蚜 enemy 2000 times liquid spray, and Alternate use.
7. Harvest at the right time. Generally, when the small melon grows to a diameter of 10 to 11 cm and a weight of 0.75 to 1 kg, the harvest is carried out. Each plant can generally harvest 7 to 10 fruits.

The Anti Rabies Vaccine For Human vaccine can prevent rabies. Rabies is a serious illness caused by a virus. The rabies virus is spread to humans through the bite or scratch of an infected animal. Dogs, bats, skunks, coyotes, raccoons, and foxes are examples of animals that can carry rabies. The rabies vaccine can protect you from infection if you are at high risk of exposure. The vaccine can also prevent infection after you are bitten by an infected animal.
