Feed beets are also called feed radishes, sweet radishes, and sugared vegetables. The seed germination temperature is 6-8 degrees, and the optimum temperature for growth is 15-25 degrees. It is conducive to the hypertrophy of leaves and the accumulation of sugar in roots in areas with warm nights and high temperature differences.
Beets are sensitive to high temperature and high temperature during seedling stage, which can form high seedlings to reduce feed quality. Feeding sugar beet requires more water, which is a hi-light and long-day crop. Insufficient light, affecting yield and sugar content. The number of hours of illumination is less than 14 hours, and it is not possible to twitch and flower normally. For planting beet, soil with flat terrain, deep soil layer and multiple humus should be selected, especially black soil type black oil sand soil and loess type butter sand soil. A suitable soil pH of 7.0-7.5 is both acid and alkali resistant. Feeding sugar beet in cold areas has high yield, good quality and is resistant to storage. It is a good feed for livestock overwintering.
Forage beets are most difficult to continue to crop, usually in 3-5 years. The best pre-crops are wheat and legumes, followed by rapeseed, potatoes, corn, flax, millet, etc. All kinds of leafy vegetables, melons and pastures are also good pre-crops. Subsequent crops can be selected for soybean, wheat and leafy crops.
Feed beets are guaranteed to have a growth period of 120 days. In the northeast, north and northwest, spring sowing is used, and sowing is carried out in two ways. The row spacing is 40-60 cm, the seeding rate is 15-22.5 kg/ha; the spacing is 50-60 cm, the hole spacing is 20-25 cm, the seeding rate is 75-15 kg/ha, and the soil is 2-3 cm. In recent years, feed beets have also introduced new technologies for paper tube seedlings and soil transplanting. After Miaoqi, we should carry out cultivating and weeding, and at the same time, weeding seedlings; 2-3 pieces of true leaf stage should be combined with cultivating and weeding to carry out seedlings; 7-8 pieces of true leaf stage seedlings, plant spacing 35-40 cm, seedlings per plant of 75,000-90,000 The fertilizer field should be thin, and the thin field should be dense. Feed beets have a long growing period, high yield, and require more fertilizer. Generally, there are many nitrogen fertilizers in the early stage of fertility, and more phosphorus and potassium fertilizers are needed in the later stage. Each time heighs 150-225 kg of ammonium sulfate (or 105.0-127.5 kg of urea) per hectare, 300-450 kg of superphosphate, roots are applied deep, and water is applied after application.
Feed beets are generally harvested in mid-to-late October. Feeding roots can be freshly stored or silaged. Feed beets are valuable succulent feeds in autumn, winter and spring, and contain high levels of nutrients. Its crude fiber content is low and easy to digest. It is an excellent succulent feed for sheep. The beet leaves are soft and juicy, fresh or can be stored. The fleshy roots are high-quality succulent feeds for livestock in winter, which are conducive to improving the health of livestock and increasing the rate of products. However, it is not suitable for feeding rams, which may cause urethra stones. Chopped or crushed, mixed with bran, or cooked with concentrate. The roots of the frozen storage in the north are quickly washed and pulverized, and then frozen and mixed into the concentrate, which is to be opened and then fed.

Multi Span Plastic Film Greenhouse
Arch greenhouse is a kind of economical greenhouse, which is welcomed by the users with graceful curve form and low cost. It has beautiful appearance, fluent visual, reasonable structure and good performance for keep temperature. It is economical greenhouse because of its relatively low manufacturing cost. It can be applied in most areas of China. Double membrane greenhouse is used more in north of China, while single film greenhouse is used more in southern region. It can get maximum sunlight when visible light is within the scope of 0.4 to 0.7 microns and form a thick envelope, which can effectively prevent heat loss and prevent the invasion of cold air. Adopting a double membrane can greatly improve heat preservation performance of the greenhouse and save operating cost. The top cover material is polyethylene lifelong anti-fog and anti-dipping film po-covering. The outer of it has the function of UV protection and the inner has the function of preventing from the sets of dew. According to the needs of customers, the sides of the greenhouse can be covered with polyethylene lifelong anti-fog and anti-dripping po-covering or polycarbonate hollow plate.
