Broccoli seedling management method

Broccoli is a kind of cauliflower vegetable, which is widely distributed in China and is favored by many people. The planting area of broccoli is expanding with the market demand. Broccoli has different management points at each growth stage. Among them, the management of seedling stage is very important, so how to manage broccoli at seedling stage? The following editor has brought you the seedling management method of broccoli, let's have a look!

1. Regular observation

During the period of non-germination of broccoli after sowing, its germination must be observed regularly and checked twice a day. Mainly check germination, soil moisture and light intensity. In the environment of high temperature in summer, we should pay attention to controlling the temperature and watering reasonably to control the soil temperature. Keep the soil temperature at about 26 degrees. To promote the normal germination of seeds to break the soil, watering should pay attention to the time, not at noon. And pay attention to the weather changes to prevent rain after watering. Finally, do a good job of shading to prevent direct sunlight and affect the emergence of seeds.

2. Temperature control

Temperature is very important for the growth of broccoli seedlings. Before emergence, the temperature is controlled at about 22 degrees, and the temperature difference between day and night is about 10 degrees. Then the temperature should be reduced by 5 degrees after emergence. Temperature discomfort will not only reduce the germination rate of seeds, but also affect the growth of seedlings. As a result, the growth ability of seedlings decreased and the growth of seedlings was weak. Therefore, we should adjust the temperature according to the growth of broccoli seedlings to prevent temperature discomfort, affect the normal growth of broccoli and reduce the planting efficiency.

3. Timely seedling refinement

A week before broccoli seedlings are planted, seedling refinement should be done. Improve the adaptability of seedlings, properly watering after sowing, and increase soil water content. Then uncover the straw after the seedlings are complete, and properly control the soil at about 75%. Attention should be paid to ensuring proper light when refining seedlings, so it is necessary to remove the sunshade net in time to provide sufficient light for seedling growth, but also pay attention to sunlight intensity to avoid direct sunlight on seedlings, resulting in seedling burns. In addition, it is necessary to do a good job in the prevention and control of diseases and insect pests, control the serious harm of diseases and insect pests and reduce the survival rate of seedlings.

4. Pest control

Disease and pest control of broccoli at seedling stage is also very important. The common diseases and insect pests in broccoli seedling stage are blight, jumping beetle and so on. These diseases and insect pests will harm all parts of broccoli in varying degrees, resulting in serious effects on the growth of broccoli. Therefore, we must do a good job in disease and pest control of broccoli. Seed dressing should be carried out before sowing to improve the disease resistance of seeds. Then strengthen the management, check frequently, and if there is any abnormal situation, we should take corresponding measures in time.

The above is a brief introduction to the management methods of broccoli at seedling stage. The seedling management of broccoli is very important, which directly affects the growth ability and yield of broccoli. So we must pay more attention, today's introduction is here, this article is only for reference, I hope it can be helpful to everyone!
