How to Grow Broccoli from Seed and Key Points for Seedling Stage Management

Broccoli is a green leafy vegetable that looks very similar to cauliflower. It is deeply loved by people because of its low calorie content and high nutritional value. It is currently grown in many regions, so how do you grow broccoli from seed? How do you manage the seedling stage?

1. Introduction to broccoli:

1. What varieties of broccoli are there?

Youxiu, Weilai, Shanshui, Ludai Zi, Shenglü.

2. In which season is broccoli a vegetable?

Broccoli is generally available all year round, but its seasonal period is spring, so broccoli grown at other times is mostly cultivated in greenhouses or plastic tunnels.

2. How do you grow broccoli from seed?

1. Seed selection: What kind of seeds are good to choose?

Just choose seeds with a glossy, plump appearance and no external damage or disease.

2. Seed soaking: How long should they be soaked?

After the seeds are selected, put them in warm water at 22°C and soak them for 15 minutes, then stir continuously until the water temperature drops to 20°C and stop, finally soak them again in warm water for 4 hours, then remove and wash them.

3. Seed germination: How do you promote germination?

Wrap the soaked seeds in wet gauze, then place them at a temperature of 20°C. During development, rinse them with clean water once a day.

4. Seedbed selection: What kind of seedbed is suitable for planting?

Broccoli seeds are suitable for growing in an environment with loose, fertile soil, rich humus and good drainage and irrigation, so it is best to choose a seedbed rich in humus for planting. After choosing the seedbed, deeply plow the soil half a month before sowing, then one week in advance spread 15 kg of ternary compound fertilizer, 5 kg of calcium superphosphate fertilizer, and 2500 kg of decomposed human manure per mu, and finally level it for sowing.

5. Sowing: How do you sow?

(1) Sowing time: Generally sow in March or early July. If using a solar greenhouse, generally sow from late July to August or from early September to early October. If growing in a plastic tunnel or small arch shed, generally sow in November or January.

(2) Sowing method: Before sowing, pour a small amount of water on the seedbed, then scatter phoxim pesticide, finally evenly scatter the seeds on the seedbed, sprinkle a layer of carbendazim or dexon pesticide, lay on a shade net, and finally set up a small arch shed and cover it with another layer of shade net.

3. How do you manage the broccoli seedling stage?

1. Thinning and replanting: How do you thin and replant?

After broccoli sprouts seedlings, observe the plants frequently. Weak seedlings and dead seedlings should be removed in time, and places with dense seedlings or no seedlings should be replanted in time to ensure uniform seedlings.

2. Timely watering: How do you water?

After broccoli sprouts seedlings, keep the humidity up. Generally, water more during high summer temperatures, and at other times determine the amount of watering according to the plant growth conditions.

3. Control the temperature well: What range is good to keep it within?

After broccoli sprouts seedlings, keep the soil temperature at about 22°C and the nighttime temperature at about 12°C. If the temperature is very low, take good insulation measures, and then the seeds will be able to germinate.

4. Remove the shade net in time: When is the best time to remove it?

When the seedlings have all emerged, remove the shade net in time to provide sufficient light, but also avoid strong sunlight exposure, so in summer high temperatures provide appropriate shading to prevent the seedlings from being burned to death by the sun.

5. Pest and disease control: How do you control them?

During the broccoli seedling stage, diseases and pests such as damping-off and flea beetles are prone to occur, so it is best to take preventive measures in advance. For those already affected by pests and diseases, apply the appropriate medicine in time to reduce the occurrence of pests and diseases.

The above is a detailed introduction to how to grow broccoli from seed and seedling stage management techniques. I hope it is helpful to everyone.
