Broccoli cultivation methods and precautions

1. Maintenance methods

1. Substrate selection: Broccoli grows well in loose, breathable, well-drained acidic soil. You can mix bean dregs, animal manure or leaf mold with the soil and then plant it. You can also add nitrogen fertilizer to increase soil fertility.

2. Water management: When growing broccoli, the soil needs to be kept moist but without water accumulation. It is recommended to water it every 5 to 6 days. When it is dry and there is no rain, increase the frequency of watering depending on the situation to keep the soil moist. When it rains heavily, drain the water frequently to prevent the broccoli from getting sick.

3. Nutrient management: Apply a mixture of nitrogen fertilizer and potassium chloride two to three times during the rosette stage. Phosphorus fertilizer and nitrogen fertilizer need to be applied during the flower head expansion period. Foliar fertilizer can be sprayed with trace elements such as boron, molybdenum, and magnesium.

4. Light management: Broccoli likes to grow in places with plenty of sunlight. Adequate light can promote photosynthesis of broccoli, which not only produces sufficient nutrients for the plant, but also makes the surface of the broccoli greener and the appearance more beautiful. The sunlight is strong in summer, so take sunshade measures.

2. Breeding techniques

1. Sowing: When sowing broccoli outdoors, dig a 1.3 cm hole every 8 to 14 cm, then sprinkle a small amount of seeds in the hole, cover with a thin layer of soil, and water in time after sowing.

2. Summer: The best growing temperature for broccoli is 14℃ to 24℃. Too high temperature is not conducive to its growth. The light is strong in summer and needs shading. After heavy rainfall, drain the water in time to prevent it from rotting.

3. Problem diagnosis and treatment

1. Soft rot: It is easy to occur when there is rain or a lot of water. Bacteria will enter through the wounds on the roots, leaves, etc., causing the plant to gradually rot. Drain the water frequently in summer, and spray the soil with sulfate chain toxin diluted with water after the disease appears.

2. Cabbage worm: Cabbage worm mainly feeds on leaves. In serious cases, it will eat the entire leaf. Its feces will also affect the sales of broccoli. After discovery, it is recommended to dilute Greenworm Fungus No. 6 with water and spray it evenly on the plants.

IV. Other issues

1. Is it toxic: non-toxic. The broccoli you buy should be eaten as soon as possible. If you cannot finish it, it is recommended to blanch it or seal it with plastic wrap.

2. Can it be hydroponically grown: It cannot be hydroponically grown. Broccoli is prone to soft rot when there is too much water, so it cannot be grown hydroponically.
