The invention discloses a soilless culture method for pumpkins. The soilless culture method comprises the steps of A, preparation of organic matrixes; B, planting management: laying the matrixes on a planting
bed adopting a meshy carrier as a support, then,
sowing seeds on a base material layer, after
sowing, watering the seeds, covering a matrix layer with a thin film, after seedlings come up, removing the thin film, and ventilating the space; C, water and
fertilizer management: watering the seeds once every 2 to 4 days, and spraying
biogas slurry once every 5 to 7 days, wherein organic microelements are added in the
biogas slurry; and D, harvest: harvesting ripe pumpkins 40 to 60 days after
pollination, after 2 to 3 batches of pumpkins are born, burying stems when parts of the leaves close to the root parts are yellow, and
cutting the leaves, 1 cm to 2 cm away from the node positions, in the node positions of the buried stems. According to the soilless culture method for pumpkins, organic matters are adopted as a main material, soilless culture is carried out on pumpkins, a suitable growing environment is provided for pumpkins, a water and
fertilizer drip irrigation management method is combined, pumpkins grow vigorously, the harvest cycle is shortened, the yield is increased, the nutritional value is improved, the quality is guaranteed, and pumpkins are healthful.
