What if the cabbage doesn't have a heart?

Cabbage is a vegetable that many people like to eat very much, and it is also very common in our lives. Cabbage is a seasonal vegetable in winter, and its planting method is also very simple, but there are many people who will have cabbage without heart after planting. So why doesn't cabbage have a heart? How to prevent cabbage from not including heart? Let's find out more about it.

1. The reason why cabbage does not contain heart

There are many reasons why cabbage does not contain heart, but the most important reason is caused by low temperature and high humidity. The increase of rainfall will cause various diseases and affect the growth of cabbage, which will not only cause cabbage not to contain heart, but also may lead to plant rot and death. Secondly, improper timely fertilization, improper water supply and improper pest control are the causes of cabbage not heart.

2. Prevention methods

Because there are many reasons for cabbage not including heart, so the prevention of cabbage not including heart method also long more. Let's take a look at the specific solutions.

Scientific fertilization: fertilizer application is not right, which will lead to cabbage only long leaves, but not the heart. Many people will apply nitrogen fertilizer to promote the growth of cabbage when applying fertilizer. In fact, this is incorrect. We cannot apply nitrogen fertilizer in the planting process of cabbage. Generally, potassium fertilizer and phosphorus fertilizer should be used as the main fertilizer, and a small amount of nitrogen fertilizer can be applied. About twenty days after planting cabbage, it can be increased and applied once every half month. Secondly, when cabbage starts to wrap its heart, we need to spray foliar fertilizer once every week or so, so as to ensure the compactness of cabbage.

Humidity regulation: During the growth of cabbage, a large amount of water is required, but the water supply should be balanced, not more or less. When the weather is dry, water once a day in the morning and evening, but in case of continuous rainfall, it is necessary to drain the excess water in the field in time to avoid curling the leaves of cabbage when it rolls. To avoid water loss, we can also cover the field with straw, which can keep the soil moist.

Control the temperature: Cabbage is a winter vegetable, so this means that its cold tolerance is very good. It also means that it is heat intolerant. Then what we need to do is to control the temperature of the weather reasonably, and we can plant it by building a greenhouse to keep the temperature at a constant temperature, so that it will not affect the growth of cabbage.

Disease control: cabbage if affected by virus disease, soft rot, hanging filariasis, aphids and other diseases and insect pests, then there will be no heart phenomenon. Therefore, in the process of planting, we should observe the foliage of cabbage. If pests and diseases are found, we need to prevent them in time. Specific medications can be consulted.

Artificial heart: artificial heart is actually very simple, many growers also understand, this is also a common way for many people. In the case of cabbage without heart, many people will use straw or brown leaves to tie up the leaves of cabbage, which plays a role in assisting the heart, and the late cabbage will slowly wrap the heart.

According to the above, I believe that everyone has a certain understanding of the phenomenon of cabbage not including heart. Xiao Bian also gives you a specific introduction to the reasons and solutions for it not including heart. As long as you plant according to the correct process in the later planting process, there will basically be no phenomenon of not including heart.
