How do you prevent and control fruit abortion in zucchini? What methods are truly effective?
For zucchini fruit abortion, you can refer to the following methods for prevention and control:
1. Controlled cultivation. Keep the growing temperature for zucchini at around 25°C during the day and around 15°C at night, which favors the production, transport and accumulation of carbohydrates, and can greatly reduce fruit abortion.
2. To make up for insufficient light, plant about 2000 plants per mu. If continuous rainy days occur, spray the leaves with a sugar-nitrogen solution (0.2% monopotassium phosphate + 1% glucose + 0.5% urea) to improve the nutritional status of the plants.
3. Scientific fertilizer and water management; for early spring cultivation, cover with film on rainy days to prevent heavy rain from washing over the flowers.
4. Harvest in time; pick deformed fruits and fruits that drag down the vines early, harvest marketable fruits at the right time, and do not rush to pick half-formed marketable fruits.
5. Chemical treatment: 2-3 days after flowering, spray with 1000-500 mg/kg gibberellin and 100-200 mg/kg 4-CPA (fruit-setting hormone); both can make the young fruits grow quickly and make fruit abortion less likely.
