The main reasons for empty stalks of broccoli are: The first is the lack of boron, which is the main reason for the empty stems produced by broccoli. The second is that broccoli grows too fast during the process of flower formation. The third is the lack of water or watering during the growth period of the flower bulb. The fourth is to harvest too late. The fifth is related to the variety.
Preventive measures are as follows: 1. Select varieties that are not easily empty. 2. Reasonable application of boron fertilizer, boron-deficient soil, can be used as the base fertilizer per acre of 0.75 kg of boron fertilizer, and then 0.75 kg of boron fertilizer for extra-root fertilizer. 3. Properly dense planting to avoid empty stems due to too thin planting and too fast growth. 3. Spray the vegetables and stems before the formation of flower bulbs to enhance the anti-disaster ability, reduce the amount of pesticides and fertilizers, and reduce residual poisons. 4. Control the amount of nitrogenous fertilizer and increase phosphorus and potash fertilizers; 5. Adjust the temperature at 15°C-22°C, avoid the continuous high temperature above 25°C, so as to avoid over-concentration of nitrogenous fertilizer and continuous high temperature during the formation of flower bulbs. It grows too fast and forms empty stems. 6. Always keep the soil dry and wet, harvest timely, and prevent empty stems from being harvested too late.
