种植饲用甜菜需要大量的养分。只有施足肥料才能获得高额产量。每亩饲用甜菜对纯养分需要量约为12至13公斤氮,8至10公斤磷酸,16至20公斤苛性钾以及4至5公斤镁。一般在秋季施苛性钾—磷酸盐基肥。如因各种原因而未在秋季施基肥,也必须在春季及早补施。值得建议的是,可用苦土钾盐镁矾供给一半的苛性钾,另一半用颗粒苛性钾供给。施过钾盐镁矾的饲用甜菜在夏季抗旱能力较强。苛性钾肥料的构成和施用量应为:约67至80公斤/亩苦土钾盐镁矾和20至27公斤/亩颗粒苛性钾,这样可同时满足饲用甜菜对镁的需要。
Growing fodder beets requires a lot of nutrients. Only enough fertilizer to obtain high yields. The pure nutrients required per mu of sugar beet are about 12 to 13 kg of nitrogen, 8 to 10 kg of phosphoric acid, 16 to 20 kg of caustic potash and 4 to 5 kg of magnesium. Kashkari generally in the fall of potassium - phosphate-based fertilizer. If, for various reasons, the base fertilizer is not applied in autumn, it must also be replenished early in the spring. It is worth recommending that half of the potash can be supplied with bitter aurite and the other half supplied with granular caustic potash. Feeding beet with potassium alum as alum has strong drought resistance in summer. The composition and application rate of caustic potash fertilizer should be about 67 to 80 kg / mu of bitter aurite and 20 to 27 kg / mu of granular caustic potash, which simultaneously satisfies the magnesium requirements of fodder beet.
