山东省种植甜菜已有十多年历史。近年来每年种植甜菜有20多万亩,年产量有2万多吨,甜菜生产有发展的趋势。目前山东甜菜生产上最突出的问题是春菜块根含糖低,一般含糖为14—15度。其主要原因是8月份多雨、高温致使甜菜褐斑病发生严重,影响了块根糖分的积累,糖度降低。为扭转低糖局面,其有效途径是甜菜生产布局应变春播为夏播。夏播甜菜块根一般含糖为16—17度,比春播糖分提高1—2度。以山东高密县500吨糖厂为例,如果甜菜糖分提高一度,每年可多给国家创造财富80多万元的资
Shandong Province has planted sugar beet more than ten years of history. In recent years, there are more than 20 million mu of sugar beet planted each year and the annual output has more than 20,000 tons. The development of sugar beet industry has a tendency of development. At present, the most prominent problem of beet production in Shandong is that the root vegetables contain low sugars, with the sugar content of 14-15 degrees. The main reason is the rainy in August, high temperature caused serious occurrence of sugar beet leaf spot, affecting the accumulation of sugar content in roots, reducing sugar content. In order to reverse the situation of low sugar, the effective way is that the beet production layout strain spring sowing is summer sowing. Summer sowing beet root sugar content of 16-17 degrees, 1-2 points higher than the spring sowing sugar. Take Gaomi County, Shandong Province, 500 tons of sugar mills, for example, if the sugar beet once increased once each year to create more than 80 million state-owned assets
