目前额敏糖区甜菜栽培较难掌握的技术仍然是保苗。由于春季气候多变,常常出现干旱、大风,造成土壤失墒,加上病虫危害以及耕作技术方面的原因,甜菜缺苗断行或大面积毁种现象经常发生。一、充足的底墒甜菜是深根作物,幼苗生长缓慢且时间长,约需1个多月,苗期不宜灌水。甜菜种子很小,萌发时需吸收种球重的1.2～1.6倍的水分。充足的底墒才能保证出全苗和苗期植株的正常生长。
The current beet sugar sugar beet cultivation is more difficult to grasp the technology is still seedlings. Due to the changing climate in spring, drought, wind gusts, soil moisture loss, pests and diseases as well as farming techniques are the common causes of beetle lack of seedlings or extensive deforestation. First, adequate moisture at the end Beet is a deep root crop, seedlings grow slowly and for a long time, about 1 month, seedling should not be irrigated. Beet seeds are very small, germination need to absorb bulbs 1.2 to 1.6 times the weight of water. Adequate end moisture to ensure the normal growth of seedlings and seedling plants.
