What fertilizer is good for pumpkin topdressing?

Pumpkin topdressing time

After transplanting the pumpkin, you can water it thoroughly once. After the seedlings have grown, use diluted urea water to irrigate it 1-2 times to promote seedling growth. Top dressing is generally done 2-3 times.

What fertilizer to use for pumpkin topdressing

Top dressing can be applied at the base of the pumpkin seedling stage. When entering the fruiting period, fertilizer needs to be applied to both sides of the ridge. Generally, it is applied in strips. On calcareous soil, nitrogen fertilizer needs to be applied deeply and then covered with soil, especially ammonium bicarbonate, the depth of which should be more than 6 cm, and then covered with soil.

Should I use urea or compound fertilizer for pumpkin topdressing?

It is better to use urea as top dressing for pumpkin. Ammonium bicarbonate will be applied during the growth period. Note that it should be applied more than 6 cm deep and covered with soil, otherwise the fertilizer efficiency will be reduced. Chemically stable nitrogen fertilizers such as ammonium sulfate and urea can be used for top dressing in combination with watering.

Pumpkin topdressing method

When the pumpkin enters the middle growth stage and grows 1-2 young pumpkins, you can apply fruit-promoting fertilizer heavily. Generally, biogas slurry is applied as topdressing. The topdressing is mainly quick-acting nitrogen fertilizer, combined with phosphorus fertilizer and potassium fertilizer. The amount of topdressing generally accounts for half of the total amount of fertilizer. Topdressing should be carried out according to the different amounts of nitrogen, phosphorus and potassium required by the pumpkin at different growth stages.

Pumpkin topdressing dosage

Before land preparation for pumpkin, generally 15,000-30,000 kg of manure is applied per hectare, or the base fertilizer application ratio of zucchini can be referred to. Each row of pumpkin occupies one old bed and one interbed, with a width of about 1 meter and a plant spacing of about 40 centimeters. There are about 12,000 plants per hectare, and 15,000 plants if more are planted.

Precautions for pumpkin topdressing

Pumpkin is suitable for planting in sandy loam. The land should be prepared 20 days before sowing. The planting rows should be slightly higher than the stems and vines. This will facilitate topdressing and watering in the middle and late stages and prevent the pumpkins from rotting. High-quality farmyard manure and compound fertilizer can be applied. The fertilization depth is 15 to 20 cm, and it should be wide rather than deep. It is best to apply it in trenches to increase the root area, and it is best not to apply it in holes.
