甜菜单位面积产量是由株数和单株重构成的,而单株重与含糖量之间又有密切关系。在一般情况下,含糖量随着块根增大而增加,500克时达最高值。超过这个数值,含糖量则随着块根的增大而逐渐下降。现在实行以质论价收购,甜菜生产必须兼顾产量和含糖量。甜菜出苗后,适当多留苗是实现高产、高糖行之有效的技术措施。甜菜播种多采用开沟条播的办法,出苗较密集,这对多留苗是十分有利的。在5月下旬,当甜菜长有
The yield of beet per unit area is composed of the number of plants and the weight of the plant, and the weight of the plant and the sugar content are closely related. Under normal circumstances, the sugar content increases with the root tuberosity increased to 500 grams reached the highest value. Beyond this value, the amount of sugars gradually decreases with increasing root tuber. Now the implementation of qualitative parity acquisition, beet production must take into account the yield and sugar content. Beet emergence, the appropriate multi-seedling is to achieve high yield, high sugar effective line of technical measures. Beet seeding and planting more ways to use trenching, more densely populated, which is more advantageous to stay young seedlings. In late May, when beets grow
