摘　　要：饲用型甜菜作为一种家畜饲料作物,具有块根含糖率低、产量高、适口性好等特点。为研究饲用型甜菜在西藏的适应性,对饲用甜菜品种甜饲1号和斯特品种在林芝县和白朗开展播期、密度和施肥等试验研究,结果表明,在白朗县,甜饲1号和斯特品种播期4月25日和4月30日时产量最高;斯特品种播期为5月5日时产量最高;白朗及类似区域甜菜适宜密度是40cm×35cm。斯特和甜饲1号和斯特在林芝播期2月底至3月初时产量最高,甜菜在林芝县及类似地区最适宜密度是50cm×30cm。由此可得在林芝和白朗等县类似区域适宜的饲用甜菜播期、密度和施肥等。As a kind of feed crop for domestic animal, forage beet has the characteristics of low sugar content, high yield and good palatability. In order to study the adaptability of forage sugarbeet in Tibet, the experiment on sowing time, density and fertilization of forage sugarbeet varieties Tianci No. 1 and Ster were carried out in Nyingchi and Bailang counties. Results showed that the yield of the two cultivars reached the highest on April 25 and April 30, the highest on May 5, and the optimum density of sugarbeet in Bailang county and similar areas was 40 cm ×35 cm. During the end of February to the beginning of March, the yield of Sugarbeet was the highest, and the optimum density of sugar beet in Nyingchi and similar areas was 50 cm×30 cm. The suitable sowing time, density and fertilization of forage beet in similar areas such as the county of Nyingchiand Baiang were summarized.
