The pumpkin has the characteristics of strong cold-resistant and low-temperature growth, and can use the spring early-maturing cultivation technology to raise the morning market, fill the market gap, and obtain higher economic benefits. Now is the time for the early spring pumpkin nursery. Here are the technical points for using the greenhouse and Yangshuo to cultivate pumpkin seedlings for reference by the friends of Guaran.

First, nursery

In North China, early spring pumpkin nursery takes place in a greenhouse or in Yangshuo. The appropriate sowing date is generally from late February to early March.

Second, soaking germination

Fight with 100°C hot water for 5 seconds, immediately cool the cold water to 30°C and stir for half an hour, then soak in fresh water for 8-12 hours. During this time, wash seeds with warm water at 30°C for 2 or 3 times to remove mucus from the surface of the seeds. 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 °C ~ 30 °C, 2 ~ 3 days, when the bud length of 0.2 ~ 0.5 cm, the seed radicle exposed, commonly known as dew, you can sow, the general amount of 200 grams per mu.

Third, sowing

Seedlings are commonly used to raise seedlings, and 2kg of 40% carbendazim powder per cubic meter of seedling substrate is disinfected prior to loading. The seedling substrate was sprayed with fresh water so that the moisture content reached 70%. When the nursery substrate is loaded, a 2 cm deep space is reserved for the cup. Each seedling cup was sown with one seed of germinated seeds, covered with 2 cm thick expanded vermiculite, and then covered with a mulch. You can also use germination live field.

IV. Seedling management

After sowing, the temperature is maintained at 25°C-30°C during the day and 18°C ​​at night. When 60% of the seed is arched, the film is removed and the temperature is reduced to 20°C-25°C during the day and 12°C-15°C during the night to prevent seedling growth. When the heart blade is 2 cm long, the daytime temperature is maintained at 25°C to 28°C and 15°C at night. Spray fresh water every 5 days during nursery. When the seedlings have 2 leaves and 1 heart, they are planted with a nursery substrate.
