Causes of cracking in cabbage and its control measures

Cabbage is a common cabbage in our life, which is deeply loved by many people, and there are also many growers, but there are many farmers' reaction that cabbage has the phenomenon of cracking, which is very easy to occur in the later stage of cabbage growth. So what is the cause of the kale crack? How to prevent and cure it? Let's take a look at the detailed introduction.

1. Symptoms of fissure ball

The common symptoms are cracking at the top, some side cracking, generally strip cracking, and vertical and horizontal cross cracking, which will expose the leaf tissue inside. The degree of cracking varies from several layers of leaves outside the bulb, and the depth of the crack varies. Leaf ball cracking not only reduces the commercial nature of leaf ball, but also causes leaf ball infection and rot, losing edible value and commodity value.

2. The cause of cracking ball

There are many reasons for the cracking ball of cabbage, one is the variety reason, if the varieties of flat head type or round head type are planted, it is easy to crack ball in the later stage; second, the moisture in the soil is uneven, and the leaf ball tissue of cabbage is relatively fragile and tender, if there is too much water in the soil, its tissue will cause leaf ball expansion due to excessive water absorption, or it will also cause leaf ball cracking in case of heavy rain or heavy water irrigation after heading. Third, if the harvest is too late, it will also cause cracked balls; fourth, it is easy to crack balls in warm winter weather after overwintering cultivation in the open field in the south.

3. Preventive measures

First of all, it is necessary to select suitable varieties, plant varieties that are not suitable for split balls, and choose flat, convenient drainage and irrigation, fertile and loose soil, or high border planting in order to drain water. Watering should be reasonable and appropriate, mainly soil moisture, avoid flooding, and stop watering in the later stage of leaf bulb growth, so as to avoid leaf bulb cracking. When cultivated in the open field in the south, water and fertilizer should be properly controlled to avoid early heading of cabbage. When it is estimated that cracking occurs, part of the root system should be cut in advance to inhibit plant water absorption.

4. Remedial measures

When a slight rupture of the leaf ball is found, the sprain yield should be carried out in time to reduce the absorption of nutrients and water by the root system and reduce the degree of crack ball. The specific practice is to grasp the slightly broken leaf ball with both hands, shake it left and right several times, and break the fibrous root, but the main root is not broken, making it in a pseudo-planting condition. For the cracked leaf balls, they should be harvested in time and should not be left in the field to get sick.
