What causes low sugar content in sugar beets? The latest control measures are here

Sugar beet is an important cash crop and attracts many farmers to plant it, but during the growing process farmers encounter the phenomenon of low sugar in sugar beet. So what causes the sugar content of sugar beet to decline? How should it be solved? Follow the editor and take a look.

I. Causes

1. Climatic effects

From May to September, rainfall is negatively correlated with the sugar content of sugar beet. If there is too much rainfall, the soil water content increases, which will cause the sugar content of sugar beet to decline, and a large number of new leaves will form, 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 beet. 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, while sowing over a long period will affect the synthesis and transfer of carbohydrates, thereby lowering the sugar content. Applying little or no organic fertilizer, especially excessive nitrogen fertilizer in the late growth stage, will also cause the amount of harmful nitrogen in the root to rise and the sugar content to decline. If thinning and final thinning of seedlings are done too late at the seedling stage, the young seedlings will compete for water and nutrients, and normal plants will press against each other, causing the sugar content to decline.

II. Control measures

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

2. When planting, choose flat terrain, deep soil layers, and medium-to-upper fertility plots, ensure smooth drainage and irrigation, and do a good job of deep application of base fertilizer and 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, prepare the land into a ready-to-sow state, and in the following spring simply harrow and level it before sowing.

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

5. Strengthen field management, promptly control pests and diseases, thin and final-thin seedlings early, and eliminate weed infestation in the middle and late stages; large weeds in the late stage have a relatively large impact on sugar content. Carry out foliar spraying at the seedling stage or late stage to supplement nutrients for the plants, and 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.
