The causes and Control methods of the latest Sugarbeet Hollow

The hollow phenomenon often occurs in the process of sugar beet planting, which seriously affects the varieties of sugar beet and brings economic losses to farmers, so measures must be taken to prevent and cure the disease. So what is the reason why beets are hollow? How to prevent and cure it? Let's take a look at the detailed introduction with the editor.

1. Hollow cause

It is mainly caused by different environment and improper management, which leads to the uncoordinated cell division rate and volume growth of beet root head, so the hollow phenomenon appears. In sugar beet cultivation, it is easy to encounter a rainy climate, so there is plenty of water. Root head cell division is accelerated, the volume growth of leaves is faster, but in the later stage of dry climate, cell division and volume growth are inhibited, resulting in the formation of hollow phenomenon. In addition, improper cultivation management will also form hollow, irrigation is one of them, excessive planting density, partial application of nitrogen fertilizer and other reasons will increase the probability of hollow, they will lead to root growth, leading to cell division too fast. In addition, diseases and insect pests are also one of the causes of hollow, artificial breaking leaves, resulting in new regeneration, the rotation of new and old leaves is too fast, causing root elongation, leading to an increase in the probability of hollow.

II. Prevention and control measures

The main results are as follows: 1. First of all, it is necessary to cultivate the soil deeply when planting, so as to create a good soil environment to make the root tuber grow normally and inhibit the root tuber growth.

2. when planting, it should be planted reasonably according to the local actual situation, and it can be sparsely planted in the land where Rain Water is abundant and the accumulated temperature is high, while on the contrary, the land with less Rain Water and low accumulated temperature should be planted properly. If the soil is loose and fertile and rich in organic matter, those with more fertilizer can be sparsely planted; on the contrary, it can be planted so closely.

3. When fertilizing, we should pay attention to the application of nitrogen fertilizer, so as not to cause overgrowth of the plant. Reasonable nitrogen, phosphorus and potassium should be used to make the plant grow fast and well. There is a special fertilizer for sugar beet on the market, which can be applied directly.

4. It is necessary to irrigate in time during drought, but it is not suitable for flood irrigation to avoid root growth. It is suitable for small water irrigation or sprinkler irrigation to keep the soil water content at about 80%, which is conducive to the accumulation of sugar beet.

5. For the prevention and control of diseases and insect pests, especially brown spot, at the same time, when breaking the leaves, try to break the outer functional leaves, so that the plant can carry out normal photosynthesis, which is conducive to the accumulation of nutrients.

The above are the reasons for the hollow sugar beet and the introduction of prevention and control methods, hope to help you, want to know more related knowledge, please pay attention to us.
