How to plant broccoli seeds

Broccoli, also known as green cauliflower, broccoli, broccoli, broccoli or American cauliflower, is a common vegetable grown all over the world. Let's learn how to plant its seeds.

How to plant broccoli seeds?

1. Preparatory work

The cultivation of broccoli should choose loose soil with high dryness, good drainage, ventilation and light, rich in organic matter, farming, fertilization, disinfection and weeding before sowing. At the same time, soil moisture must adjust the seedbed, the soil moisture is too small, affecting the expansion and germination of seeds; if the humidity is too high, the soil will be closed.

two。 Sowing seeds

Soak the seeds in 50 ℃ warm water for 25 minutes before sowing to kill the bacteria that sneak into the seeds. Broccoli can be planted in the open air after the Qingming Festival in spring, or in late summer and early autumn, and in Zhejiang from July to October. Then the seeds of the treated broccoli were evenly sown on the prepared seedbed, covered with fine soil, and sprayed with fine nozzles to make the seeds come into close contact with the surface of glutinous rice.

3. Administration and Management

During the whole germination period, it is necessary to observe the field in the morning, in the evening, and in the field to observe seed germination, soil moisture on dough and sunshine intensity or drainage intensity on rainy days. During the period of sunny day and high temperature from July to September, the germination and seedling stage mainly rely on watering to adjust the soil temperature to keep the soil temperature at the suitable temperature of 25-30 °C for the benefit of normal emergency. Watering can be done in the afternoon and evening to avoid overcast and rainy weather after watering. During this period, cover the sunshade net for 2-3 days and nights to cool down and rain, and wait for two emergency cotyledons to lift the sunshade when green.

4. Transplant

Before transplanting, farm manure was used as base fertilizer, all were applied, ploughed and broken, cultivated in high border in rainy season, double-row cultivation in 1 meter open border, flat bed and wide border in dry season, and plastic film should be covered in autumn and early spring. Planting as much as possible with more soil, less root injury, reduce slow seedling stage, after transplanting. Water management should be strengthened.

In the later stage, we can do a good job of field management like other crops.
