Recently, the loofah flowers of vegetable farmers in Shaanxi and other places have experienced water rot symptoms, which are wet and odorous and have odor. Because loofah is required to sell flowers, the loofah flower is abnormal, which has a great influence on the commercial nature of loofah. How to prevent it?
Loofah water burnt flower is caused by bacterial diseases. It can cause the disease of loofah water stab, and there are many diseases caused by vines, blight, bacteria, gray mold, etc., and the blackness of the style will occur when calcium deficiency occurs. Once the loofah appears to be watery, it is irreversible after administration, which will directly reduce its commodity value. Therefore, the loofah water burnt flower should be based on prevention, and it can be carried out by preventing and adjusting daily management in advance.
Precautions to prevent water burnt flowers
Practice has proved that 2-3 days before the flowering, spraying the agent for prevention can have a multiplier effect. The agent can be used with procymidone + metalaxyl + chrysanthemum.
When the flowers are scented, the above-mentioned agents for preventing the disease of the loofah water, such as charcoal, enoylmorpholine, and serotonin, are added to the anthers.
Timely flowers, supplement nutrition, and improve the flower's own resistance. The loofah flower is generally open at 20-22 hours, and the flower is opened more when it is 15-16 on the next day. Therefore, it is recommended that the silk flower in the morning be the most suitable for the thickness of the petals. The petals are thicker and the cells are denser, which can reduce the infection of the disease. Loofah needs a lot of potassium fertilizer and calcium fertilizer during the fruit expansion period. Spraying high potassium and high calcium leaf fertilizer on the leaf surface after silk flowering can not only make the loofah expand rapidly, improve its hardness and the brightness of the melon skin, but also the petals will harden. Thicken and improve disease resistance.

It is recommended that the vegetable farmers pour the straw through the small water, operate the straw and rationally release the wind, adjust the humidity inside the shed, avoid condensation on the loofah flower, and cause harmful bacteria invasion. Dyeing, causing water to burn. It is worth noting that within 1-2 days after watering, the ventilation time should be extended by the method of gradually releasing the air to accelerate the humidity reduction in the shed. Do not let the wind out too much at one time, causing the loofah to flash, and there is a problem with the dry side.
