In order to strengthen the guidance of sugar beet production in autumn, the National Agricultural Technology Extension Service Center and the Ministry of Agriculture and Rural Sugar Experts Guidance Group researched and formulated the “Guidelines for Autumn Production Technology of Sugar Beet in 2019†according to the production characteristics of sugar beet production areas. The general requirements are: strengthen the field management of sugar beet growth, control pests and diseases, control nitrogen and water, harvest at the right time, and effectively increase the sugar content and quality of sugar beet roots.
First, strengthen field management
Nitrogen fertilizer is no longer applied in the later stage of beet growth and the amount of water is controlled. Avoid artificial damage to beet leaves to reduce production. For sugar beet in drip irrigation mode, the drip irrigation facilities should be recovered in time before harvesting; the sugar beet should be recovered before harvesting, and the residual film on the surface should be removed manually after harvest.
Second, prevention and control of pests and diseases
The late growth stage of sugar beet is a key period for sugar accumulation. Due to the excessive rain in the early stage, it is necessary to timely control the occurrence of diseases and insect pests of sugar beet leaves, especially attention to diseases such as sugar beet brown spot, root rot and powdery mildew, and beet cabbage night. Prevention and control of pests such as moth, Lithium californica and spider mites. For the beetroot rot and tuberculosis occurrence plots, it is recommended that the growers carry out centralized inventory and deep burial treatment during the harvesting process; for heavy weed plots, the grass can be properly removed manually to reduce miscellaneous Grass damage, weeds with lighter weeds may not be removed, try to prevent damage to functional leaves.
Third, timely harvest storage
Weather changes should be closely monitored and harvested in time before the frost arrives. Large-scale growers can harvest by combined harvesting or segmentation, and small-scale scattered growers can harvest by segmentation. In the case of unacceptable machine, mechanical excavation, manual picking and cutting, or cutting with a cutting machine, mechanical digging and manual picking can be used. When stacking after harvesting, it is necessary to pay attention to the ventilation and ventilation of the piles to prevent mildew and decay. Beets should be sold in time after collection. Beets that cannot be sold in time should be carefully stored, improve storage quality, and reduce “frozen vegetablesâ€.

Polysaccharide powder can be divided into the following categories:
Starch: such as amylose, amylopectin, etc., is the most common polysaccharide in plants.
Glycogen: Mainly found in animals, it is a form of energy storage.
Cellulose: The main component of plant cell walls, not digested by the human body.
Chitosan (chitin) : found in the shell of crustaceans.
Dextran: such as yeast dextran, etc., has certain immunomodulatory effects.
Other polysaccharides: such as xanthan gum, guar gum, etc., are widely used in food, medicine and other fields. Polysaccharide powder mainly has the following effects:
1. Providing energy: For example, glycogen stores and provides energy in animals.
2. Immune regulation: Some polysaccharide powder has the function of immune regulation, can enhance the body immunity.
3. Moisturizing effect: It can play a role in moisturizing and moisturizing skin in cosmetics.
4. Thickening stability: In the food industry can increase the consistency and stability of the product.
5. Promote gut health: Certain polysaccharides act as prebiotics, promoting the growth of beneficial bacteria in the gut.
