Planting and management techniques of broccoli

Broccoli is a kind of flower ball vegetable, although it is not native to China, it also has a history of introduction and cultivation for many years. Cultivation, including management skills are very rich, planting methods, as well as the cultivation process, the final management work, in fact, there are certain requirements and attention, can not be carried out at will. If you want to know something about this, you can take a look.

1. Planting

Planted seeds should be treated before sowing, soaking solution, soaking seeds to accelerate germination, if they are packaged seeds, they may have been sterilized and can be soaked directly. Sowing, exposing white buds should be covered by soil to avoid water evaporation and bud withering. Moisturizing is a work that needs to be paid attention to before emergence to the seedling stage. Don't lose water. But the seedbed do not accumulate water, stagnant water retting. Seedlings mainly pay attention to disease management, and seedlings are most prone to quenching disease. Humidity control is an effective method to restrain the disease.

2. Cultivation

Seedlings grow to 7 to 8 centimeters can be transplanted, transplanting early, not too late, the root system is just in time to transplant. The seedling is so old that it hurts a lot of roots when it is pulled out. Transplanting seedlings can be planted deeper to protect root growth. It recovers quickly. Don't usually refine the seedlings at this time. Attention should be paid to slowing down seedlings and providing water and nutrition. After the growth is restored, the main thing is to top fertilize, water, weed and promote growth. Planting between rows should not be too dense, leaving a gap for the growth and heading period.

3. Management

Management includes some contents such as fertilizer, water and soil nutrition, diseases and insect pests and so on. At the beginning of the heading period, we gradually need to increase the amount of fertilizer to meet the needs of nutrition. Finally, we should pay attention to the supply of soil nutrition. The soil itself has certain natural nutrient elements, but it is easy to be consumed with growth. Therefore, we should pay attention to fertilization supplement, especially some trace elements, can not be lacking. During the growing period, it is easy to produce some diseases, such as downy mildew or brown spot, which harm branches and leaves and flower heads. Emphasis should be placed on prevention and control.

4. Pay attention

The flower bulb of broccoli grows gradually, and if there is a disease that harms the flower ball, the loss is relatively large. High temperature and humidity will cause some diseases, which is the cause of the disease, whether it is planting in open field or greenhouse, it is necessary to cool down and control humidity. Drought is beneficial to some insects and can be harmful, which can be prevented and reduced in advance. High temperature and drought do not apply fertilizer, less fertilizer, choose the right fertilization method.

Broccoli cultivation can be from the seed to the bulb mature process, which separately introduces the management, regulation, matters needing attention. Therefore, the management should pay attention to the growth stage. It can't be managed as usual. Or the completion is not in place.
