在同样环境条件下,甜菜的根产量及根中含糖率,是由品种特性所决定的,即由该性状的遗传性所支配,故而有丰产型与高糖型品种之分。但是,甜菜又是可塑性较强的作物,不同的土壤气候条件、施肥水平、灌溉条件、种植密度和农业技术措施等对甜菜的根产量和糖率都会产生不同的影响。在选用优良品种前提下,创造适宜的生育环境.是提高甜菜单位面积产糖量的关键。目前甜菜单产较低。其原因种种,而甜菜疏苗早晚,也 Under the same environmental conditions, the root yield of beet and root sugar content, is determined by the characteristics of the variety, which is dominated by the trait of the trait, so there are high-yielding and high-sugar varieties of the points. However, sugar beet is a more malleable crop. Different soil and climatic conditions, fertilization levels, irrigation conditions, planting density and agricultural techniques have different impacts on root yield and sugar content of sugar beets. In the selection of good varieties under the premise of creating a suitable reproductive environment is to improve sugar beet per unit area of ​​the key to the amount of sugar. Currently beet yield is low. The reason for all kinds, and sugar beets seedling sooner or later, also
