When is the best time to plant broccoli?

The sowing time of broccoli needs to be precisely controlled to ensure its normal growth. Sowing too early may cause the cabbage to bolt before winter and suffer frost damage. In the southern regions, it is recommended to sow and raise seedlings in early September. The sowing time should be avoided before August 20 and after September 20, because the cabbage sown during these two time periods is prone to bolting, which is not conducive to the formation of buds. In addition, excessively high temperatures will also affect the development of buds, causing the plants to bolt and bloom. Therefore, choosing the right sowing time is crucial for the healthy growth of cabbage.

Seedling raising: Before sowing, fertile and well-drained land should be selected as the seedbed. Deeply plow the land, level it, apply fully decomposed farmyard manure, and mix it evenly with the soil. Water thoroughly before sowing, and the sowing amount is about 70 to 100 grams per mu. Keep the soil in the seedbed moist to promote emergence. After the seedlings emerge, control the water content appropriately to prevent the seedlings from growing too tall. At the same time, thin out the seedlings 1 to 2 times to cultivate strong seedlings.

Land preparation: Choose a plot that has not been planted with cruciferous crops, plow the land 20 to 25 cm deep, and make raised ridges about 1 meter wide. About 4,000 kg of farmyard manure and 25 to 30 kg of phosphate fertilizer are applied per mu as base fertilizer. Use the nest application method to ensure that the fertilizer is fully mixed with the soil before planting.

Transplanting: Transplanting of broccoli is usually done 30 to 40 days after sowing, when the seedlings grow 5 to 6 true leaves and reach a height of 18 to 20 cm. The planting density is generally 2,000 to 2,400 plants per mu, and the row spacing is maintained at 57 to 60 cm. Planting usually takes place in October.

Field management: After transplanting, apply clear manure water in time when the seedlings are acclimatizing. After that, apply decomposed human and animal feces and urine once every half a month, with the concentration ranging from light to heavy. Before the New Year, the use of quick-acting nitrogen fertilizer should be strictly controlled to prevent the cabbage from growing too vigorously. 0.2% potassium dihydrogen phosphate solution can be sprayed 2 to 3 times. Around the beginning of spring, apply urea twice, 30 to 40 kilograms per mu each time. Keep the soil moist, cultivate and weed regularly, and prevent and control diseases and insect pests in a timely manner.

Harvesting: When the fleshy stems of choy are fully developed and the green flower buds begin to appear, they should be harvested in time.
