Muskmelon greenhouse cultivation: cultivation of strong seedlings
July 12, 2024
The seeding period sowing time is restricted by the ground temperature of the greenhouse during the planting period, and the general greenhouse can be planted when the ground temperature is stable above 12°C. The seedling period is generally 1 month. Therefore, the time for the first month or so is the appropriate sowing date. Sowing and nursery are usually conducted in a hotbed. The sowing time of greenhouses in various parts of China is: Shanghai is in early February and Zhengzhou is mid-February. Beijing in late February, Lanzhou in early March, Daqing in mid-March. This season nursery uses a nursery in the shed to hold a small shed. It is best to use an electric hotbed to raise seedlings.
Seed treatment and pre-germination sowing should be preceded by heating the hotbed, seedbed irrigation, so that the ground temperature of 5 cm above 20 °C. Seeds sown after sowing were removed and dried, and seeds were treated after drying (see “Sowing and Seedling” in General Management Measures). The soaking and germination selection is carried out in the morning, and the cloth sprouting method is adopted. After 16 to 18 hours, the seed is budded. When the bud grows to 0.5 to 1 cm, the seeds that are germinated are sown, and germination is continued without germination.
Seeding sowing on a sunny day with a cold tail warmer. First, dig a hole a depth of 1 cm in the center of the nutrition bowl, then place the seeds flat in the pot with the buds facing down and cover the soil to a thickness of 1.5 cm. After sowing, close to the bed cover a layer of film, and then set up a small arch shed, arched film tension, surrounded with soil compaction.
The management of the seedbed management seedling stage has an important influence on the differentiation of flower and leaves of the muskmelon. Therefore, the management work during this period is very important. For detailed measures, see the general management measures in this chapter.
