Master orchid seedling-raising techniques, and the fertilization techniques for broccoli

Broccoli is a vegetable that many friends like. During the process of growing broccoli, appropriate fertilization is also needed. So how is broccoli fertilized? Below, I will introduce the fertilization techniques for broccoli.

How to fertilize broccoli

Cultivation, weeding, and earthing up. After broccoli is planted and has recovered from transplanting, carry out the first cultivation. Where it is far from the seedlings, cultivate deeply; where it is close to the seedlings, cultivate shallowly to prevent root damage. While cultivating, earth up around the base of the seedlings to prevent them from falling over. Afterward, combine topdressing and watering to cultivate and earth up 2 more times, but it must be ensured that the roots are not damaged.

Fertilizer and water management. Broccoli is a vegetable that requires a relatively large amount of fertilizer, especially the dual-purpose types for both terminal and side heads and the mid-to-late maturing varieties. During the growing period, multiple topdressings are still needed to make the plants grow robustly and obtain a relatively high curd yield. Generally, 10-15 days after the seedlings have recovered from transplanting, apply the first topdressing, using 10 kg of urea, 15 kg of diammonium phosphate, and 7.5 kg of potassium sulfate per mu. During the curd expansion period, a 0.05%-0.1% borax solution and a 0.05%-0.1% ammonium molybdate solution can be sprayed on the leaves, which can improve the quality of the flower buds and reduce the occurrence of yellow buds and scorched buds. After the terminal curd is harvested, an appropriate light topdressing can be applied once to increase the yield of side curds and extend the harvest period. However, in the later growth stage, nitrogen fertilizer must not be applied in excessive amounts to avoid rotting.

Fertilization techniques for broccoli

Broccoli likes moisture and is not drought-tolerant. Throughout the entire growth process, it needs a relatively large amount of water. In the event of an autumn drought, after planting, water once every 5-7 days to ensure that the soil is often kept in a moist state. After each topdressing, water should also be applied in a timely manner to help the roots absorb nutrients. Broccoli likes moisture but is also afraid of waterlogging. When watering, avoid flood irrigation. In case of heavy rain, promptly drain the field water. After the rosette stage, appropriately control watering to prevent excessive vegetative growth. After small curds form, water promptly once the curd diameter reaches 2-3 cm to promote rapid expansion. For special-purpose varieties grown for terminal curds, side buds should be removed before the curd is harvested. For special-purpose varieties grown for terminal curds, side branches sprout relatively abundantly; generally, only 4-5 robust side branches are retained, and thin, weak side branches are removed, which can reduce nutrient consumption. When the daily average temperature is below 10°C, in order to concentrate nutrients for supply to the main curd, side branches should also be removed as early as possible.

The above is an introduction to the fertilization techniques for broccoli. Friends who grow broccoli can refer to the above fertilization techniques according to the actual growing conditions and fertilize reasonably.
