Analysis of the Causes of Cabbage Head Splitting and Control Measures

Cabbage is the common cabbages we see in daily life, loved by many people, and quite a lot of people grow it, but many farmers have reported that cabbage shows head splitting, a phenomenon that very easily occurs in the late growth stage of cabbage. So what causes cabbage head splitting? How should it be prevented and controlled? Let's take a look at the detailed introduction.

1. Symptoms of head splitting

The common symptom is splitting at the top, with some splitting on the sides, generally linear splitting, and there is also crisscross splitting, which exposes the leaf tissue inside. The degree of splitting ranges from splitting of several outer layers of leaves of the head, with the depth of the split varying. Head splitting not only reduces the marketability of the head, but also causes the head to be infected by pathogens and rot, losing its edible value and commercial value.

2. Causes of head splitting

There are quite a few causes of cabbage head splitting. First, the variety: if flat-headed type varieties or round-headed type varieties are planted, they are prone to head splitting in the late stage; second, uneven moisture in the soil: the head tissue of cabbage is relatively crisp and tender, so if there is too much water in the soil, its tissue will swell and split the head due to absorbing too much water, or splitting can also occur when heavy rain or heavy irrigation occurs after head formation; third, harvesting too late can also cause head splitting; fourth, in open-field overwintering cultivation in the south, when head formation is followed by warm winter weather, head splitting very easily occurs.

3. Preventive measures

First, choose suitable varieties and plant varieties that are not prone to head splitting, and select flat terrain with convenient drainage and irrigation and fertile, loose soil, or use high beds for planting to facilitate drainage. Watering should be reasonable and appropriate, mainly keeping the soil moist, avoiding flood irrigation, and watering should be stopped in the late stage of head growth to avoid head splitting. In open-field cultivation in the south, water and fertilizer should be properly controlled to avoid early head formation in cabbage, and when head splitting is expected to occur, part of the root system should be cut in advance to inhibit water uptake by the plant.

4. Remedial methods

When slight splitting of the head is found, twist and injure it in time to reduce the roots' absorption of nutrients and water and lessen the degree of head splitting. The specific method is to grasp the slightly split head with both hands and shake it left and right several times to break the fibrous roots while the main root remains unbroken, putting it in a state of temporary planting. For heads that have already split, harvest them in time; they should not be left in the field to become diseased.
