Common problems in planting Chinese cabbage in early spring

There are many problems with cabbage in early spring, and the environmental factors at this stage bring more problems because the weather is relatively changeable. When planting cabbage, many people have suffered losses. Here we synthesize some common problems. If you want to improve your planting efficiency, you might as well learn about it!

1. Temperature leads to slow growth

Many people find that the growth of cabbage at this stage is obviously slower than that of other times, and there is no difference between planting in all aspects and before, but the growth of cabbage is not good. In fact, this may be caused by the temperature. We all know that the temperature at the beginning of spring is not very stable, but the growth of cabbage needs a relatively stable temperature. When the temperature is high, it grows faster, and when it is low, it grows slowly. As high and low as the beginning of spring, the growth of cabbage has changed, one is fast and the other is slow, and it takes time to adapt, which leads to a gap between the growth of cabbage and other times.

2. there are many deaths after emergence.

The problem of low survival rate after emergence is also relatively common. Most of the seeds germinate after planting, but they begin to die in bulk after emergence. This situation is generally caused by the environment. As mentioned earlier, the temperature at the beginning of spring is unstable, the cabbage seedlings themselves are relatively fragile, the external environment changes frequently, and the seedlings will not stand this change and eventually die. Seeds can germinate because of the barrier of soil, which gives the seeds a relatively safe space, and the emergence of seedlings is in direct contact with the outside world, which is also one of the reasons for the high mortality of Chinese cabbage after emergence.

3. Excessive stagnant water

There is relatively much rain this season, and a lot of farmland needs to be prepared for spring ploughing. Every place begins to store water to raise the field, and if there is more, it will be discharged, and many vegetable fields are relatively close to farmland. Finally, there is too much water in the vegetable field. I believe we all know the harm of too much water. In addition, shortly after the beginning of spring, many people have not yet had time to improve the drainage channels, which aggravates the stagnant water, so we should prepare for waterproofing before planting cabbage and prepare for drainage after planting, otherwise these cabbages may be planted for nothing.

4. Serious decay

The problem of cabbage rot is also more common this season, one water rot is caused by soft rot, the former is caused by too much precipitation, and the latter is due to the slow recovery of latent diseases and the erosion of cabbage at this time. Bugs are not very common at this time, so focus on prevention in view of these two situations. Soft rot occurs very quickly in the case of too much water, so we must pay more attention to whether there is such a situation in the vegetable field.

These are the common problems when Chinese cabbage is planted in early spring. In this changeable stage, we need to take more care to manage when planting, so that the harvest will be good.
