近年来在提高甜菜含糖率和块根产量的讨论中,有些资料曾提出,由于生产实践中甜菜基本不施钾肥,限制了甜菜产量和含糖率的提高,从而建议有关部门向甜菜产区调入钾肥,或者提供氮磷钾复合肥料。然而目前有关甜菜由于施用钾肥而增产增糖的试验报道还不多见,所以对于当前甜菜生产不施钾肥的现象,可以有两种理解,一种是施肥不合理,另一种是施钾肥增产增糖效果不显著。为了探索钾肥对甜菜产量和含糖率的影响,我们从1980～1983年进行了甜菜施用钾肥的试验,结果如下。
In recent years to improve sugar beet sugar content and tuber yield discussions, some data have suggested that due to the basic practice of sugar beet does not apply potassium, limiting sugar beet yield and yield increase, suggesting that the relevant departments to the sugar beet Potash, or NPK fertilizer. However, there are still few reports on the sugarbeet yield increase due to the application of potash fertilizer. Therefore, there are two understandings about the current phenomenon of not applying potassium fertilizer to sugar beet production. One is irrational fertilization and the other is the increase of yield of potassium fertilizer The effect of adding sugar is not significant. In order to explore the impact of potash on sugar beet yield and sugar content, we conducted a test of potash application of sugar beet from 1980 to 1983 with the following results.
