III. Pumpkin planting techniques

1. Planting: when there are 3-5 true leaves, strong, disease-free and pest-free seedlings can be selected in the sunny afternoon, 1 plant per pot, the planting depth should be cotyledon flat soil surface, and watered thoroughly. If it is direct seeding, it is necessary to remove the sick seedlings and leave 1 seedling in each hole.

2. Fertilization: about 10 days after planting, sparse organic fertilizer was sprayed once, mainly nitrogen fertilizer. The plant grows rapidly after climbing the vine, and the first topping is carried out at the time of 8-10 true leaves, which promotes the sprouting of lateral vines, and the bracket can be set up in advance. When the lateral vine is more than 50 cm long, you can collect tender stem tips and petioles to eat, pay attention to retain about 5 leaves, and use larger soil clods to press the remaining stem vines to promote the germination of aerial roots. The rarefied mature organic fertilizer dominated by nitrogen fertilizer was sprayed once after each harvest.

3. Bracket: when the vine goes around the basin on the soil surface, it can pull the stem vine to climb the support, so that the leaves are evenly distributed and the branches do not block each other.

4. Growth: after a certain stage, the plant enters the flowering stage, and the male flowers are mainly male flowers at the beginning. When the flowers will not bloom in the morning, the male flowers and pedicels can be picked together for consumption. When the female flower began to grow, the mature organic fertilizer was mainly phosphorus and potassium fertilizer, and the young stem tip was reduced or stopped harvesting. If necessary, artificial pollination must be carried out before 8 o'clock in the morning. Usually there are 3-5 melons per plant for normal growth (1-2 large melons, micro melons can be increased appropriately, depending on the growth of the plant), too many young melons or female flowers should be thinned, and the stem vines should be properly topped to avoid insufficient nutrient supply. Larger melons can be hung in a firm place with net pockets, and melons close to the ground can be isolated from the soil with foam or wood pads.
