When is the best time to plant broccoli?

Broccoli, also known as green cauliflower, broccoli , etc., is a very common vegetable . It has bright colors, crisp taste, high nutritional value, and has good planting prospects. So when is the best time to plant broccoli? Let’s learn more about it below.

When is the best time to plant broccoli?

Broccoli is a cool-loving vegetable. The best growing temperature is 15 to 21 degrees. The best planting season is mainly in spring or autumn. In spring, sowing is generally carried out in mid-March and harvesting is carried out in early June; in autumn, sowing is generally carried out in July and harvesting is carried out in mid-September.

Key points of broccoli planting technology

1. Seedbed selection

The seedbed should be selected on high, fertile, well-drained sandy soil. Avoid planting cabbage and Chinese cabbage vegetables in the previous crop. Before sowing, apply 15-20 kg of decomposed compost per square meter, dig trenches with a width of 40 cm on a 1.5-meter clean bed surface, and level the bed surface.

2. Sowing and seedling raising

The sowing of broccoli is the same as that of cauliflower. It is better to sow dry seeds, which have a higher germination rate. Use 20-30 grams of seeds per acre. Generally, broadcast sowing is used. After all the water in the seedbed has seeped down, a thin layer of sieved fine soil is first spread to prevent the seeds from sticking in the mud and to increase air permeability to facilitate germination. Then spread the seeds evenly on the bed surface, cover them with 0.5 cm thick sifted fine soil immediately after sowing, and then cover the seedbed with a film to increase temperature and retain moisture.

3. Transplanting and planting

When the seedlings have grown 5-6 true leaves and are 30-35 days old, they can be transplanted and planted. When transplanting, make small high ridges with a ridge width of about 80 cm and a ridge ditch of 30 cm. There are two rows on each ridge, and the spacing between plants is 40-50 cm. About 2300-2700 plants are planted per acre.

4. Field management

After planting, water should be poured in time to restore the seedlings, and weeds should be weeded on time. In the middle period, top dressing should be carried out in combination with inter-cultivation. Dig trenches to build up soil around the roots to prevent drought and waterlogging, and observe carefully to prevent and control diseases and insect pests in a timely manner, and prune and remove side branches in a timely manner. Wiping off weak side branches can save nutrients for the growth of main branches and flower balls.

5. Harvest at the right time

The best time for harvesting is in the morning and evening. When harvesting, keep 3-4 leaflets around the flower head to protect the flower head. The broccoli tissue is crisp and tender. It should be harvested and transported gently. It is best to use plastic baskets or cartons, and do not fill them too full to prevent crushing.

In general, broccoli can be planted in spring or autumn, and it is recommended to sow and raise seedlings in a solar greenhouse, which can achieve early maturity and high production efficiency.
