Turmeric, also known as turmeric, is suitable for growing in sub-tropical climates and can be planted both in the north and south regions of the Yangtze River. Ginger is made from tubers and is rich in diosgenin, curcumin and other valuable substances. The saponin that has been hailed by the medical community as "medicinal gold" is extracted from turmeric. First, the cultivation of yellow ginger technology 1. Tuber breeding turmeric in the annual heavy snow to the cold and before and after the vernal equinox, such as tubers for cultivation, when the late autumn mining, such as seeds sown, the harvest should be 2 years - 3 years is better The output of mu is 8000 kilograms, and the annual output of mu is about 3,600 yuan. Tuber propagation can be carried out from the beginning of October to the end of March of the following year. The digging seeds can be selected and the annual robust tubers can be planted on ridges that have been well-organized and adequately basified. Ridge ridge is controlled between 1.2m and 1.5m. Before planting into the stem, you can use a hand-twisted small section of 5 cm to 10 cm, requiring two to three buds per section. The good tubers should be pushed open on the ground for 1 to 2 days. After the wound has healed, sow it so that the bacteria does not infect the wound. When planting, the plant spacing is 25 centimeters or 25 centimeters, and about 150 kilograms to 180 kilograms are planted per acre. After planting tubers with strong shoots, cover them with 2 cm of soil. At the same time, we must also pay attention to eradicate rats, so as to avoid rats digging stems, resulting in reduced production of yellow ginger. 2. Seed propagation Seed propagation is generally selected from late March to mid-April each year. Seeds are treated before sowing. Namely: Put the seeds into warm water of 30°C first, and before the seeds are put into warm water of 30°C, put 10 pieces of milled iodopyrimid sodium tablets in warm water, and then put the seeds and soak them in warm water for one day. One night, after which the seeds are drained and mixed with about 2.5 kg of dry fine sand, spread and then spread. The soil is then covered with 2 cm thick, and slightly pressurized. Each seed is about 1.5 kg per 667 square meters. After covering the soil, pesticides were sprayed to prevent the insects from biting off the shoots after being unearthed. Afterwards, a thin layer of dry straw or dried thatched grass is covered, but it is better to use low-temperature plastic greenhouses to control temperature and germination, so as to ensure that the seeds will be fully emerged after 15 days to 25 days after sowing. When the drug seedlings are completely uncovered, the cover can be gently removed in time. Second, field management When turmeric seedlings come out, you can pour a light human urine, can also be poured a lighter compound fertilizer. About 35 kg per mu. After the compound fertilizer is applied to the water, do not rush to pour all the fields. You can try to pour the seedlings of 1 square meter first. Observe the seedlings on the 2nd to 3rd days after pouring. If no fertilizer is caused, use it again. The same concentration is applied to all the fields. Fertilization usually 5 times - 6 times a year. And weeding soil in time. When the turmeric seedling grows to 30 cm, a small bamboo rod can be inserted between the plants for climbing and shading of the yellow ginger vines, and after the “spring vernal equinox†of the second year, the maize can be planted after the growing season and the vegetables with shorter growth period can be grown. Class, while intercropping corn can still be harvested by 70% to increase the value of land and income. Third, harvesting and processing Huang Jiang excavation time is generally in the late autumn season, north of the Yangtze River in the late October excavation, the area south of the Yangtze River in early November excavation. After the excavation, the soil and fibrous roots are removed and cut into 0.5 cm pieces of ginger, dried and packaged for sale.
