How to prevent and control flower and fruit drop in zucchini? Please advise on methods.
Flower and fruit drop in zucchini can be prevented and controlled by referring to the following methods:
Strictly control temperature. During the flowering and fruiting period of zucchini, keep the temperature inside the greenhouse at around 26°C during the day and no lower than 15°C at night.
Remove and cover the straw curtains in a timely manner. Remove and cover the straw curtains in a timely manner to extend the lighting time as much as possible and increase light intensity.
Strengthen water and fertilizer management. If the plant leaves are dark green and thick, yet the plant flowers without setting fruit, water and fertilizer must be strictly controlled, and a larger clod of soil should be used to press down the vine tip to inhibit excessive vegetative growth. If the plant is weak and the leaves are yellow and thin, water and fertilizer must be increased, and the first female flower should be removed to promote vegetative growth.
Prevent and control diseases and pests in a timely manner. Prevent and control diseases and pests in a timely manner, strengthen ventilation, reduce humidity inside the greenhouse, apply pesticides regularly, remove fallen petals and diseased or old leaves, and smear a layer of carbendazim powder on the spot where the petal is attached at the top of the zucchini fruit. This can prevent pathogens from invading the fruit through this spot and causing it to drop.
Supplement boron fertilizer in a timely manner. When flower buds first appear on zucchini, spray chlorophyll or Spraying Treasure on the leaves once every 10 days or so to prevent poor development of flowers and fruits caused by a deficiency of trace elements such as boron, which can lead to flower and fruit drop.
Prevent poor fertilization. At around 10 a.m., select female flowers that are about to open, and dip the flowers in a mixed solution of 2,4-D at a concentration of 20×10-6 and gibberellin at a concentration of 30×10-6 to promote fruit enlargement and prevent poor fertilization.
