Breeding method of storage-resistant pumpkin

The invention discloses a breeding method of storage-resistant pumpkin. The breeding method comprises the following specific steps: seed treatment; preparation of nutrient soil; seedling stage management: regulating and controlling the bed temperature after sowing so as to promote seedling emergence, removing mulching films and other coverings when the seedling emergence rate reaches 70%, carrying out seedling hardening 7 days before field planting, and transplanting when the seedling age is 20-25 days; soil preparation: combining soil preparation with ploughing, applying 2500-3000 kg of a high-quality organic fertilizer and 30 kg of a ternary compound fertilizer per mu, adopting deep furrows and high ridges, keeping the ridge width to be 3-3.5 m, planting one row of seedlings in each ridge, and covering with a mulching film one week before transplanting; field planting: covering with a mulching film during field planting, digging field planting holes according to the plant spacing of 0.4-0.5 m, performing fi
