2. Using nutritious earthwork to raise seedlings. First of all, a seedbed is arranged in the seedling raising facility, and nutrient soil with a thickness of 10 cm is laid in the seedbed, trampled flat and watered. After water permeates, divide it by 10 cm, and prepare for sowing. When sowing, plant the germinated seeds in the middle of the nutrient surface.
3. Nursery seedlings in nutrient pots. First, choose a suitable nutrition bowl. At present, the diameter of nutrition bowls is mostly 5 ~ i3 cm. The application method is also very simple. Arrange the seedbed first, then spread a thin layer of fine sand on the bed surface, put the plastic seedbed with a diameter of about 10cm into the seedbed, squeeze the pipes together, and then irrigate and sow. The function of fine sand is to isolate the soil. When planting, it is only necessary to isolate seedlings along fine sand, which is beneficial to the operation and protection of pumpkin roots.
4. The seedling tray is used to raise seedlings, which can be moved and replaced at any time, which is conducive to regulating the growth of seedlings and making full use of protective facilities. If conditions permit, the seedling tray can be used for three-dimensional seedling raising to make full use of space.
5. Using plug seedling is more convenient for seedling management and planting operation, which is beneficial to protecting root system. At present, plugs with different holes can be bought on the market. Because pumpkin leaves are large, grow fast, and need a large nutrient area, it is best to use a large hole plate, at least 72 holes. But in fact, the 72-hole seedling tray can't fully meet the needs of pumpkin seedlings, so the seedlings can be planted when they are young, otherwise the seedlings will be crowded and easy to grow because of insufficient nutrient area.
6. Using the seedling method to cultivate pumpkin Miao Zhuang has the advantages of less root damage and quick seedling delay, which is beneficial to seedling delay and post-planting growth. There are many modes of production, among which the most widely used is nutrition bowl seedling raising.
