一、植物学特性饲用甜菜在种子发芽温度为6～8℃,幼苗在子叶期不耐冻,真叶出现后抗寒力增强,可耐-4～-6℃的短暂低温。最适生长温度为15～25℃。在黑土、砂壤土、粘土、轻度盐渍化土上均可种植。二、饲用价值多汁,富含糖分、矿物质、维生素。其根、叶中粗纤维含量低,消化率高,适口性强,是猪和奶牛以及各种家畜泌乳期的优质青饲料。如水肥条件优越,每0.067公顷可产块根15吨,鲜叶5吨。饲用甜菜封行后,每半月便可采叶一次。饲用甜菜的营养成分(占干物质%),块根:粗蛋白质13.4、粗脂肪0.9、粗纤维12.5、无氮浸出物63.4。鲜叶:粗蛋白质20.3、粗脂肪2.9、粗纤维10.1、无氮浸出物60.9。
First, the botanical characteristics of sugar beet germination in the seed temperature of 6 ~ 8 ℃, seedlings in the cotyledon is not resistant to cold, true leaves appear after the cold resistance, resistant to -4 ~ -6 ℃ transient low temperature. The optimum growth temperature is 15 ~ 25 ℃. In black soil, sandy loam, clay, mild saline soil can be planted. Second, feed value juicy, rich in sugar, minerals, vitamins. Its roots, leaves, low crude fiber content, high digestibility, palatability strong, is a pig and dairy cows and a variety of livestock during high-quality green feed. Such as water and fertilizer superior conditions, each 0.067 hectares can produce 15 tons of roots, fresh leaves 5 tons. Feeding beet seal line, every half month can be taken once. Nutrient composition of fodder beet (% dry matter), root: crude protein 13.4, crude fat 0.9, crude fiber 12.5, nitrogen-free extract 63.4. Fresh leaves: crude protein 20.3, crude fat 2.9, crude fiber 10.1, nitrogen-free extract 60.9.
