Potted pumpkin planting method

First, the variety selection: potted ornamental pumpkin suitable varieties are golden eggs, silver eggs, Wuzhishan, Jintong, jade girl, incense burner, white jade, golden apple, small wall clock, a little green, a little yellow, small pillow, crown and so on.

Second, nutrient soil preparation: use fertile pond mud or vegetable soil without melons, fully dried, broken into 1cm mud, and then add 5kg of decomposed peanut bran and straw mushroom 15kg per cubic meter; or 6 Peat soil + 3 parts of river sand + 1 part perlite mixed, then add 1kg of compound fertilizer per cubic meter to mix into nutrient soil, place the coarse grain on the bottom of the basin, and install the pot to 3/4. Ornamental pumpkins are climbing plants, and the root system is more developed. Generally, a flower pot having a diameter of 40 cm to 60 cm and a height of 30 cm to 50 cm is used.

Third, timely sowing: Ornamental pumpkins are cold and not resistant to high temperatures, and the growth temperature is 25 °C. Sowing in spring and autumn. Ornamental pumpkin, thicker seed coat. Before sowing, soak seeds and germination. Method: Wrap the pumpkin seeds in clean gauze, soak them in warm water at 30 °C for 4 to 5 hours, then rinse them clean and pick up the germination. In the early spring, the temperature is low, and it needs to be placed in a 30 °C incubator for germination. Keep the gauze moist when germination. After 48 hours, when the shoots were about 0.5 cm long, they were sown. Before sowing, the nutrient soil is drenched with water, and 3 to 4 grains are planted per pot. After sowing, the soil is covered with about 1 cm, and the water is poured. After 3 to 4 days, the seeds are unearthed. The ornamental pumpkin is mainly composed of vines and melons, and there are few side-grown melons. Because of the small size of the melons, it is suitable for vertical (frame or wall) cultivation.

Fourth, the upper pot colonization: ornamental pumpkin, root system is developed, the use of flower pots with a diameter of more than 20cm to ensure adequate nutrient area. In the upper basin, add a small amount of river sand to the bottom of the basin, then put a proper amount of sesame paste as the base fertilizer, then fill in some culture soil, plant the pumpkin and then fill the remaining soil, compact and pour water. The growth period grows with the seedlings, and the basin is changed appropriately. Generally, the small, medium and large pots are replaced three times. Before changing the basin, let the potting soil dry out, then gently tap around the basin wall, loosen it, and carefully pry it out. Before changing the basin, do not move the original soil ball to avoid injury. The rest of the operation is the same as when it was in the upper basin.

5. Timely plastic surgery: When the pumpkin plant height is about 15cm, the topping will make it branch, and when the branch grows to about 10cm, it will be topped again. Generally, it will be topped for 3~4 times, which will promote multi-branch, and the plant shape will be short and strong. Spherical plants with a height of 40cm to 50cm are more beautiful after hanging fruit. After the leaves are long and dense, the leaves need to be picked, and the old leaves with large and yellow leaves are removed to facilitate ventilation and ventilation, and the leaves are thin and thick. When picking leaves, it is found that long branches, overly branches, dead branches, and pests and branches should also be cut off to make the plants beautiful.

Sixth, management measures: 1. Temperature: ornamental pumpkin temperature, growth temperature is 15 ° C ~ 35 ° C, the most suitable temperature is 25 ° C ~ 28 ° C. In the early spring, the low temperature should be moved into the room or set of film bags to prevent cold damage, and the summer and autumn high temperatures should be cooled by cool silk shades and other facilities. 2. Moisture: The seedlings of ornamental pumpkins are drenched once every 1-2 days to keep the soil moist. The sunny days of flowering result, the water transpiration is large, the water demand is large, the water storage capacity of the flower pot is poor, and the water should be drenched every day. ~3 times. 3. Topdressing: Master the principle of “thin and hard work”. 7 days after the seedlings, 0.3% to 0.5% of the compound fertilizer aqueous solution can be applied once a week; into the flowering result period, the fertilizer needs to be large, combined with loose soil, 10g of compound fertilizer and 5g of urea per pot, and supplemented The nutrient soil is full of pots to promote root development. After that, according to the growth of the pumpkin, the color of the leaves, the results, etc., the 0.3% to 0.5% compound fertilizer aqueous solution is applied once every 10 days, and the foliar fertilizer such as 1000 times of love is sprayed 2 to 3 times to promote the growth of the pumpkin. Develop and extend the viewing period. 4. Plant finishing: When the height of the ornamental pumpkin which is mainly composed of main vines is 25cm~30cm, the vines are framed, and the frame can be fenced or iron branches, and the height is 15m~18m. In order to improve the ornamental effect and reduce the nutrient consumption, all the side branches should be cut off, only the main vines should be left, and the yellow leaves, diseased leaves and deformed fruits should be removed in time. 5. Auxiliary pollination: Artificial assisted pollination can promote the pumpkin to multi-fruit and fruit. The method is: 8~9 o'clock every morning, choose the male flower to open the day, remove the corolla, and apply the stamen pollen to the female flower stigma.

7. Harvesting: The miniature ornamental pumpkin can be harvested for about 10 days after flowering, and can be harvested when the fiber is hardened after 45 days of flowering. After harvesting the miniature pumpkins, it can be used as a fashionable toy and beautification furnishings in the home after drying, waxing, coloring and engraving.
