Causes of cabbage bolting and preventive measures

Cabbage is one of the most important vegetables in China, which is widely planted in China, and spring is the best time to plant cabbage, but the phenomenon of cabbage bolting will occur during planting, resulting in a decline in cabbage yield and affecting income. So what is the reason for cabbage bolting? How to prevent it? Let's get to know it.

1. Improper selection of varieties

There are many varieties of cabbage, the characteristics of different varieties are not suitable, some varieties are strong in winter, and some varieties are weak in winter, so the bolting rate is also different. in general, the varieties with weak winter are easy to bolting, while the varieties with strong winter have low bolting rate.

Prevention methods: so in the selection of varieties is to choose strong winter, reduce the early bolting rate, increase the yield.

2. Improper sowing time

The sowing time of cabbage will also affect its bolting rate to a certain extent. if the sowing time is too early, the seeds will be in a low temperature environment for a long time, and bolting will easily occur when the temperature rises.

Prevention method: to strictly control the sowing time, cabbage is a low-temperature vernalization plant, in a low-temperature environment for a long time, it will be very easy to bolting, many people in order to increase yield, sowing blindly, but counterproductive. When sowing, it is most suitable to sow from October to November according to the local climatic conditions.

3. The temperature is not suitable

In the cabbage seedling stage, if the temperature is too high, even if the capture time is applied, it will lead to the rapid growth of seedlings, and the bolting phenomenon will occur when the accumulated temperature is completed during planting.

Prevention method: the temperature must be controlled well, when the temperature is too high and the seedling growth is exuberant, it can control the occurrence of the seedling and inhibit its growth, so as to prevent the seedling from overwintering and bolting after spring.

4. Improper planting time

If the plant is too large when the seedling is planted, it is easy to bolting when overwintering, and the time of planting is also very important. if the planting is too early, the seedling has been subjected to low temperature for a long time, and bolting has occurred. Bolting will also occur if the planting is too late to meet the low temperature duration of the seedlings.

Prevention methods: when planting, we must control the planting time and the size of seedlings, according to the size of seedlings, reasonable regulation of fertilizer and water, so that it can survive the winter smoothly, and bolting will not occur.

The above is the introduction of cabbage bolting causes and prevention methods, hope to help you, want to know more related knowledge, please pay attention to us.
