How do you plant pumpkin seeds?

Shandong area is called hanging melon, and the northeast region is called Japanese melon. Edible, there are orange and cyan, the shape is flat round or irregular gourd shape, immature fruit skin crisp meat dense, can be served, stuffing, ripe fruit sweet noodles, can cook porridge, the most widely planted in northeast China, let's take a look at how to grow pumpkin seeds!

Disinfection of pumpkin seeds

Seed disinfection pumpkin seeds are dried in sunny days before seed soaking. Seed disinfection should be carried out before seed soaking. The methods of pumpkin seed disinfection are as follows:

1. High temperature sterilization: soak the seeds in warm water of 55 ℃ for 10 minutes, and constantly stir until the water temperature is 30 ℃, keep the seeds heated evenly, the hot water should be about 5 times the amount of seeds, and then soak the seeds for 3 or 4 hours to prevent pumpkin mosaic virus disease.

2. Chemical sterilization: soak the seeds in clean water for 4 hours, soak the seeds with 1% copper sulfate for 5 minutes, or soak the seeds with 0.1% potassium permanganate for about 30 minutes, or soak the seeds with 40% formaldehyde 100 times solution for 20 minutes. Soak the seeds with 70% carbendazim or 50% carbendazim wettable powder 500 times solution for 30 minutes to prevent anthracnose. Then rinse with clean water, drain slightly, prepare to go to bed and sprout, mix seeds with 90% trichlorfon powder, direct seeding can prevent ants and underground pests from biting.

Accelerated germination of pumpkin seeds

The optimum temperature for pumpkin germination is 28030 ℃. If possible, constant temperature incubator can be used to accelerate germination. The soaked seeds are wrapped in a wet cloth and put into 28030 ℃ incubator.

Pumpkin seeds can be germinated with an electric blanket to lay out the normal use of the electric blanket, and a layer of quilts and other materials can be padded under the electric blanket to facilitate heat preservation, then lay the prepared plastic film on the electric blanket, disinfect the towels used for sprouting, etc., after disinfection with boiling water, wring by hand (it is appropriate to screw the towels without dripping but oozing water between the fingers), spread them on the plastic film, and drain the pumpkin seeds slightly after seed soaking and disinfection. Tile it on the towel.

Direct sowing in the field

When sowing directly in the field, you can prepare the ground in the winter of the first year and apply sufficient base fertilizer, and then bury the pumpkin seeds in February and March of the second year. Because the seedlings grow long and grow fast, you need to apply fertilizer in April, May and June, and pay attention to watering. Pumpkin management is relatively extensive, because the root system is developed, leaf internodes take root, so we should pay attention to soil cultivation in order to absorb nutrients. A pumpkin can produce many branches, in order not to disperse nutrients too much, to fork, a seedling leaves 2-3 main vines, and according to the soil fertility and seedling growth, after several births can hit the top bud.

Pumpkin as long as fertile soil, frequent watering and fertilization, generally 3-5 leaves slip a melon, leaving more melons do not grow, melon axils are very easy to branch buds, we should pay attention to remove, otherwise compete with melons for nutrients, so that melons lack nutrients and wither and fall.
