Three points for the early spring pumpkin nursery

1. Soak germination with 100°C hot water for 5 seconds, immediately cool the cool water to 30°C and stir for half an hour, then soak in fresh water for 8-12 hours, wash the seeds with warm water at 30°C for 2 or 3 times to remove the seeds. Surface mucus. After the seeds were removed, they were allowed to dry for 2 hours until the surface of the seeds was dry and germinated. When the germination temperature is maintained at 28 to 30°C, after 2 to 3 days, when the shoot length is 0.2 to 0.5 cm, the seed germ roots are exposed, commonly known as dew, and can be sown.

2. Before seeding, use a new high fat film seed dressing to repel the underground pests and isolate the virus infection without affecting the germination and ingestion function, strengthen the respiratory intensity, and increase the seed germination rate.

3, seedling management, the temperature during the day to maintain 25 ~ 30 °C, 18 °C at night. When 60% of the seed arched, remove the film, the temperature dropped to 20 ~ 25 °C during the day, 12 ~ 15 °C at night, to prevent seedlings grow. Spray fresh water every 5 days during nursery. Seedlings with 2 seedlings were planted with medium for seedlings. After spraying the new high-fat film in a timely manner, it can effectively prevent the ground water from evaporating, the seedling body water from transpiration, isolation of pests and diseases, shortening of the seedling-reducing period, rapid adaptation to the new environment, and healthy growth.
