Interesting, exquisite and ornamental methods for potted ornamental pumpkin

Ornamental pumpkin, bright color, there are monochrome, bicolor, dichromatic, etc., the fruit interesting, exquisite, strange shape, strong ornamental, not only can be planted in open field, greenhouse, but also can be cultivated in flowerpots, both ornamental and edible.

Potted pumpkin

Variety selection: the suitable varieties of potted ornamental pumpkin are golden egg, silver egg, Wuzhishan, golden boy, jade girl, incense burner, white jade, golden apple, small wall clock, little green, little yellow, pillow, crown and so on.

Second, the preparation of nutritious soil: choose fertile pond mud or unplanted vegetable garden soil, fully dry and break into 1cm mud, then add 5kg mature peanut bran and straw mushroom mud 15kg per cubic meter; or mix 6 parts of peat soil + 3 parts of river sand + 1 part of perlite, and then add 1kg compound fertilizer per cubic meter to form nutritious soil, the coarse grains should be placed at the bottom of the basin and placed in the basin to 3 parts 4. Ornamental pumpkin is a climbing plant with well-developed root system and needs to be cultivated. Generally choose the flowerpot with caliber 40cm~60cm and 30 cm~50cm high.

Third, sowing at the right time: ornamental pumpkin likes cold and can not bear high temperature, and the suitable temperature for growth is 25 ℃. Sow seeds in spring and autumn. Ornamental pumpkin, the seed coat is thicker. Before sowing the seeds, soak the seeds to promote budding. Methods: the pumpkin seeds were wrapped with clean gauze, soaked in 30 ℃ warm water for 4 hours, then scrubbed clean, picked up and germinated. If the temperature is low in early spring, it should be placed in a 30 ℃ incubator to accelerate germination. Keep the gauze moist when sprouting. After 48 hours, the seeds were sown when the buds were about 0.5cm long. Before sowing, sow the nutritious soil with water and sow 3-4 seeds in each pot. after sowing, cover the soil with about 1cm and drench with sufficient water. after 3-4 days, the seeds will be unearthed. Ornamental pumpkin is mostly the main vine melon, side vine melon is very few, because the melon is small, suitable for vertical (shelf or wall) cultivation.

Fourth, planting in the pot: ornamental pumpkins have well-developed roots. Flowerpots with a diameter above 20cm should be used to ensure adequate nutritional area. When putting on the basin, add a small amount of river sand to the bottom of the basin, then put an appropriate amount of sesame sauce residue as base fertilizer, then fill in part of the culture soil, plant pumpkins and then fill the rest of the soil, compacted and watered once. Grow up with the seedling during the growing period, change the basin appropriately, generally change the small, medium and large basin for 3 times. Each time before changing the basin, let the basin soil dry thoroughly, and then gently pat around the basin wall, after loosening, carefully knock out. Before changing the big basin, do not touch the native ball, so as not to hurt the root. The rest of the operation is the same as when you put it on the basin.

Fifth, timely plastic surgery: ornamental pumpkin plant height about 15cm hit the top, make it branch, branches grow to about 1Ocm again hit the top, generally hit the top 3-4 times, to promote multi-branching, plant shape short and strong, the formation of 40 cm~50cm high spherical plants, so that hanging fruit more beautiful. After the leaves are long and dense, you need to pick the leaves and remove the large, withered and yellow old leaves, so as to facilitate ventilation and ventilation, enhance the light, and make the leaves thin and thick. When picking leaves, it is found that long branches, over-dense branches, withered branches, disease and insect branches should also be cut off to make the plant beautiful.

VI. Management measures:

1. Temperature: ornamental pumpkin likes temperature, the suitable temperature for growth is 15 ℃ ~ 35 ℃, and the optimum temperature is 25 ℃ ~ 28 ℃. Low temperature in early spring should be moved indoors or covered with thin film bags to prevent cold, east harm, high temperature in summer and autumn should be cooled by cool yarn shade and other facilities.

two。 Moisture: the ornamental pumpkin is watered every 1-2 days to keep the soil moist. On a sunny day during the flowering and fruiting period, the water transpiration is large, the water demand is high, and the water storage capacity of the flowerpot is poor. Water should be drenched 2-3 times a day.

Pumpkin pollination

3. Topdressing: master the principle of "applying thin fertilizer frequently". From 7 days after intercropping, 0.3%-0.5% compound fertilizer solution can be applied once a week; when entering the flowering and fruiting stage, a large amount of fertilizer is needed, combined with loosening the soil, 10g compound fertilizer and 5g urea are applied in each pot, and nutritious soil is added to the full basin to promote root development. Since then, according to pumpkin growth, leaf color, results and other conditions, 0.3% 0.5% compound fertilizer solution was applied every 10 days, and foliar fertilizer such as 1000 times of Aiduo harvest was sprayed 2 times 3 times, in order to promote the growth and development of pumpkin and prolong the viewing period.

4. Plant finishing: in the main vine melon-based ornamental pumpkin plant height 25cm~30cm, set up to draw vines, scaffolding can be made of hedge bamboo or iron branches, stand 15m~18m. In order to improve the ornamental effect and reduce the nutrient consumption, all the lateral branches should be cut off, leaving only the main vine, and the yellow leaves, diseased leaves and deformed fruits should be removed in time.

5. Auxiliary pollination: artificial pollination can promote pumpkin to set more fruit and bear good fruit. the method is as follows: at 8: 9 o'clock every morning, choose the male flower on the same day, remove the Corolla and apply the stamen pollen to the female flower stigma.
