Broccoli cultivation and management technology

Broccoli is also called broccoli. Its edible part is green flower ball, which is rich in nutrients. It is the best vegetable among cabbage vegetables. Now it is mostly used for health care because broccoli has strong resistance to diseases and is now used by farmers. My friends plant it extensively, so what cultivation and management techniques does broccoli have? Let's understand!

Broccoli cultivation and management technology

1. Site preparation

Generally, before planting, it is necessary to turn over the land, dig up suitable planting holes, apply 1500 kg of decomposed farm manure per mu, and about 50 kg of compound fertilizer, and mix it with the soil evenly.

2. Cover film

In order to retain water, fertilizer, heat, and inhibit the growth of weeds, the membrane must be covered. After the membrane is covered, the edge of the membrane is pressed with a soil block.

3. Perforate the plastic film above the pond during planting, plant the seedlings, and cover the joint of the seedling root neck and the plastic film with soil. Then pour enough root water to facilitate survival.

4. Planting management

(1) Topdressing: Broccoli requires a large amount of fertilizer. Topdressing nitrogen fertilizer at the seedling stage promotes vegetative growth, controls fertilization in the middle period, prevents excessive growth, and re-attacks the ball fertilizer later to promote flower ball hypertrophy.

(2) Moisture: The growth of broccoli needs to keep the soil moist. Generally, watering is carried out after top dressing, and the supply of water is controlled to make the broccoli balls expand more and increase production.

(3) Main diseases and insect pests and control techniques: Broccoli has strong disease resistance and is not harmful to pests. Common diseases and insect pests include downy mildew, soft rot, diamondback moth, cabbage worm, and vegetable aphid.

Diseases: Downy mildew is susceptible to black rot in the early stage, and can be controlled by Bacillium Chloride, Dicloxone, and Phaihaiying. If a disease occurs in the later stage, it will seriously threaten the quality of broccoli, so it is necessary to spray Streptomyces sulphate in time To prevent and control.

Insect Pests: Pests that commonly occur are Plutella xylostella, Pieris rapae, and Aphis vulgaris, which require farmers to use decontamination, acetamiprid, and hanging silkworm alternate spraying for prevention and control.
