Key Technical Points for High-Yield Cultivation and Management of Cauliflower

Cauliflower, also known as caihua and broccoli, is a vegetable we commonly eat in daily life. It tastes good, is highly nutritious, and delivers fairly decent economic returns, so it is widely cultivated across the country. However, if you want to earn higher profits, you need to find ways to increase the yield. So how should cauliflower be managed to achieve high yields? Let's take a look.

1. Raising Strong Seedlings

Raising high-quality seedlings is one of the keys to achieving a high yield of cauliflower. First, choose land with good drainage and irrigation conditions that is loose and fertile. Then, while preparing the land, apply decomposed organic fertilizer, disinfect and sterilize the soil, and deep-plow and level it. Select seeds of a superior variety and sow in summer, in June-July. Before sowing, water the seedbed thoroughly, scatter the seeds evenly over the seedbed, cover with 3 cm of soil, and cover with grass for shade. Seedlings will emerge in about a week. After emergence, promptly remove the grass and set up a shade net. Once the cotyledons of the seedlings have unfolded, thin the seedlings while weeding. When the seedlings have grown 5-6 leaves, they are ready to be transplanted.

2. Transplanting

Choose a plot with high terrain, good drainage, and no tendency to waterlog. The previous crop should not be another cruciferous crop, otherwise pests and diseases are very likely to occur. When preparing the land, apply 2000-3000 kg of farmyard manure and 50 kg of compound fertilizer per mu as base fertilizer, then use flat beds or ridged cultivation. When transplanting, likewise water thoroughly, transplant with the soil ball, and take care not to damage the root system. Be sure to transplant on a sunny morning or a cloudy day to avoid strong sun exposure affecting the survival rate. Control the planting density well when transplanting; generally, 2000-3000 plants per mu is suitable.

3. Field Management

Water immediately after transplanting, then water once every 2-3 days; this helps the transplanted seedlings survive. After the seedlings have survived, carry out intertillage and weeding, but note that the intertillage depth should not be too deep, so as not to damage the roots and cause the seedlings to die. Weed frequently and keep the field free of weeds. If using ridged cultivation, before the rows close, combine intertillage with hilling and fertilizing. It is recommended to apply 10-15 kg of urea per mu, and water promptly after fertilizing so the fertilizer leaches down. When the plants begin to curl, apply 15 kg of potassium sulfate per mu, flushed with water. During the heading stage, keep the soil moist.
