Suitable seeding
Mini pumpkins have low requirements on soil conditions and are suitable for cultivation in protected or open fields on soils with good permeability and sandy soil. Regardless of the type of cultivation, nutrient seedlings should be used, and the two leaves should be planted at the same time. This saves seeds and grows strong seedlings under the protection of the facility.
1.1 Protected cultivation of small pumpkin planting period: Generally, in the middle of February, the greenhouse or the middle arch shed is used for seeding and seedling, and the two true leaves are planted in time (before and after March).
1.2 Open field cultivation of small pumpkin planting period: Generally, in the middle of March, the greenhouse is used in the greenhouse or in the middle arch, and the plant is planted in time after the night frost in mid-April.
1.3 Autumn mini pumpkin sowing period: In the middle and late July, the nursery seedlings are protected by the insect net, and the seedling stage can not be drought or flooded. The key to summer seedlings is to prevent them from contracting viral diseases.
2. Germination
The seeds are immersed in water at 25 ° C ~ 30 ° C for 6 ~ 8 hours, the seeds are removed and washed into the germination box to promote germination (temperature control at 25 ° C ~ 30 ° C), when the seeds are white, the temperature is controlled below 25 ° C, the germination time is generally 24 to 36 hours, the buds can be released, and timely sowing.
3. Sowing
The seedlings were raised with a nutrient meal of about 10 cm 10 cm. The nutrient soil is mixed with 300kg of organic fertilizer and 3~4kg of phosphate fertilizer per cubic meter, and then mixed, and then sown after watering. Each seed is placed with a sprouted seed, and then covered with fine soil about 1cm thick. After sowing, a film should be spread on the nutrient bowl to promote the emergence of moisturizing and warming, and the film should be removed in time after emergence.
4, seedbed management
During the emergence period, the daytime temperature in the shed is maintained at around 25 °C, and at night it is not lower than 15 °C. It is required that the seedlings should top the soil within 1-2 days, and the emergence of the seedlings within 3 to 4 days is most ideal. After the cotyledons are flattened, the daytime temperature in the shed is kept at around 20 °C, and at night it is kept at around 12 °C to prevent high seedlings. When the true leaves appear, the temperature during the day can be kept at around 25 °C, and at night it is maintained at around 10 °C, which is conducive to the formation of female flowers and early sitting. During the nursery period, watering can be carried out 2 to 3 times according to the soil moisture. When the seedlings have 2-3 leaves, they can be colonized (two leaves are better for conservation cultivation).
5. Colonization
The planting density depends on the cultivation mode. Generally, about 1200 plants per acre can be planted in the greenhouse. Open field cultivation (3-4 vines) can grow about 500 seedlings, and immediately watering to promote living trees after planting. In short, the planting density depends on the characteristics of the variety and the way of cultivation to determine the density and the number of vines.
6. Pruning
The purpose of pumpkin pruning is to promote the balance of the results with the long leaves. In the plots with sufficient nitrogen fertilizer, the pumpkins have strong branching power. If they grow, the branches and leaves will be excessively prosperous and prosperous. Generally, greenhouse cultivation is mainly based on single or double vine cultivation (stacking or ground climbing); open field cultivation is the most common method of planting three vines or four vines per plant (depending on the thin mantle), no matter which type of vine is used. The side branches that appear again on the vines that are kept in front of the melon should be removed in time to avoid affecting the rate of sitting.
7. Pollination
Usually the second or third female flower (9-10 blocks) is left on the main vine, and the first or second female flower is left on the side. The amount of fruit retained is related to the characteristics of the variety. Generally, 1 to 2 large varieties are kept, and 4 to 5 small varieties are left. When the female flowers are left, the blooming male flowers are removed at 7-9 in the morning, and the petals are removed and gently applied to the stigma of the blooming female flowers for artificial pollination.
8. Fertilizer management
Mini pumpkin fertilization should be applied to 200kg of commercial organic fertilizer per mus and 25kg of ternary compound fertilizer per base. Strictly control nitrogen fertilizer and watering during the flowering and fruiting period; after the melon is stabilized (large egg) combined with drip irrigation and top dressing 1 or 2 times, apply 5-10 kg of compound fertilizer per acre. In the whole life of pumpkin, the average mu of ternary compound fertilizer is 30-35kg, and urea can not be applied.
