What about beet hollowness? What is the cause?

Sugar beet often appears hollow phenomenon in the planting process, which seriously affects the variety of sugar beet and brings economic losses to farmers, so measures must be taken to prevent and control this disease. The following is to introduce the causes of sugar beet hollow and prevention methods.

I. Hollow reasons

It is mainly caused by different environments and improper management, resulting in uncoordinated cell division speed and volume growth of beet root head, so hollow phenomenon appears. Sugarbeet cultivation is prone to rainy weather, so there is plenty of water. The cell division of root head is accelerated, and the volume growth of leaves is relatively fast, but in the later stage, if the drought climate is encountered, the cell division and volume growth are inhibited, thus forming a hollow phenomenon. In addition, improper cultivation management will also form hollow, irrigation is one of them, planting density is too high, partial application of nitrogen fertilizer these reasons will increase the probability of hollow, they will lead to excessive root growth, resulting in too fast cell division. In addition, diseases and insect pests are also one of the reasons for hollowing. Artificial breaking of leaves leads to new regeneration. The rotation of new and old leaves is too fast, causing root elongation, resulting in an increase in hollowing probability.

II. Prevention and control measures

1. First of all, when planting, we should deeply cultivate the soil to create a good soil environment, so that the root tuber grows normally and inhibits the growth of the root tuber.

2. When planting, it should be planted reasonably according to the actual local conditions. The plots with abundant rain and high accumulated temperature can be planted sparsely; on the contrary, the plots with less rain and low accumulated temperature should be planted densely. The soil is loose and fertile, rich in organic matter, and the fertilizer can be planted sparsely; conversely, such dense planting.

3. Fertilization should pay attention to, should not be partial application of nitrogen fertilizer, so as not to cause excessive growth of plants, to reasonable nitrogen, phosphorus and potassium, so that plants grow fast and good, there are sugar beet special fertilizer on the market, you can directly apply it.

4. In drought, timely irrigation should be carried out, but it is not suitable for flood irrigation, so as to avoid excessive root growth. It is suitable for small water irrigation or sprinkler irrigation, so that the water content of the soil is maintained at about 80%, which is conducive to the accumulation of sugar beet.

5. For the prevention and control of diseases and insect pests should be timely, especially brown spot disease, at the same time, when breaking the leaves, try to break the peripheral functional leaves, so that the plants can carry out photosynthesis normally, which is conducive to the accumulation of nutrients.
