Sugar beet is an important cash crop, which attracts a lot of farmers' seeds, and farmers will encounter the phenomenon of sugar beet low sugar in the planting process, so what is the reason for the decrease of sugar content in sugar beet? How to solve it? Come and have a look with the editor.

First, reasons

1. Climate impact

From May to September, there is a negative correlation between rainfall and sugar content of sugar beet. if there is too much rainfall and the soil water content increases, the sugar content of sugar beet will decrease, a large number of new leaves will occur, and a lot of sugar will be consumed.

2. Cultivation reasons

Sugarbeet is a cross-pollinated crop, and the occurrence of biological confusion, variety degradation will lead to the decrease of sugar content of sugarbeet. In addition, the suitable temperature for seed germination of late sugar beet is 5 degrees, and early sowing at the right time can advance the growth process, prolong sugar accumulation, sow too long, affect the synthesis and transfer of carbohydrates, and then reduce the sugar content. Little or no application of organic fertilizer, especially too much nitrogen fertilizer in the late growth stage, will also increase the harmful nitrogen content in the root and decrease the sugar content. If the seedlings are thinned and fixed too late at the seedling stage, the seedlings will compete for water and fertilizer, and the normal plant tips squeeze each other, resulting in a decrease in sugar content.

II. Prevention and control measures

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

2. When planting, select the land with flat terrain, deep soil layer and middle and upper fertility to ensure the smooth flow of drainage and irrigation, and do a good job of deep application of basic fertilizer and winter irrigation.

3. To improve the cultivation methods, we should pay attention to plastic film mulching, timely early sowing, reasonable close planting, make the land ready for sowing before winter, and sow seeds with a little rake in the following spring.

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

5. Strengthen field management, control diseases and insect pests in time, fix seedlings as early as possible, put an end to grass shortage in the middle and later stage, and grass has a great influence on sugar content in the later stage. Foliar fertilizer was sprayed at the seedling stage or later stage to supplement nutrients for the plant. at the same time, attention should be paid to prevent the occurrence and harm of weevil, stem weevil, brown spot and powdery mildew.

6. Irrigation is prohibited in the first half of the harvest, so as not to absorb water to dilute sugar and reduce commodity value.

The above is the introduction of sugar beet low sugar causes and control measures, hope to help you, want to know more related knowledge, please pay attention to us.
