Detailed Explanation of the Causes and Control Measures of Low Sugar Content in Sugar Beets

Sugar beet is an important cash crop that attracts many farmers to grow it, but during cultivation farmers encounter the phenomenon of low sugar in sugar beets. So what causes the decline in sugar content of sugar beets? How should it be solved? Let's take a look together.

I. Causes

1. Climatic influence

From May to September, rainfall is negatively correlated with the sugar content rate of sugar beets. If there is too much rain, the soil moisture content increases, which will cause the sugar content of sugar beets to decline, and a large number of new leaves will develop, which will also consume a considerable amount of sugar.

2. Cultivation reasons

Sugar beet is a cross-pollinated crop, and biological mixing occurs. Variety degeneration will lead to a decline in the sugar content of sugar beets. In addition, sowing too late: the suitable germination temperature for sugar beet seeds is 5 degrees. Sowing early at the right time can advance the growth process and extend sugar accumulation. Sowing too late will affect the synthesis and transfer of carbohydrates, thereby reducing the sugar content rate. Applying little or no organic fertilizer, especially excessive nitrogen fertilizer in the later growth stage, will also cause the harmful nitrogen content in the root to rise and the sugar content rate to decline. If thinning and final thinning of seedlings are done too late at the seedling stage, the seedlings will compete for water and nutrients, and normal plants will crowd each other, causing the sugar content rate to decline.

II. Control measures

1. Select excellent high-sugar varieties and strengthen the breeding work of varieties.

2. When planting, choose plots with flat terrain, deep soil layers, and medium-to-upper fertility, ensure smooth drainage and irrigation, do a good job of deep application of base fertilizer, and carry out winter plowing and winter irrigation.

3. Improve cultivation methods, pay attention to plastic film mulching, sow early at the right time, and plant at a reasonable density. Before winter arrives, prepare the land into a ready-to-sow state, and the following spring it can be sown after slight harrowing.

4. Improve the level of formula fertilization, attach importance to organic fertilizer, reasonably increase the application of phosphorus and potassium fertilizers, and appropriately control the amount of nitrogen fertilizer.

5. Strengthen field management, control diseases and insect pests in a timely manner, thin and final-thin seedlings early, and eliminate weed infestations in the middle and later stages; large weeds in the later stage have a relatively large impact on sugar content. Spray fertilizer on the leaves at the seedling stage or later stage to supplement nutrients for the plants. At the same time, pay attention to preventing the occurrence and harm of weevils, stem weevils, brown spot disease, and powdery mildew.

6. Prohibit irrigation half a month before harvest to avoid water absorption diluting the sugar and reducing commercial value.
