Greenhouse pumpkin clever cultivation

Colonization Because of the great differences in climate around the country, the time for planting pumpkins is also inconsistent. As long as pumpkin seedlings can be protected from cold freezing and normal growth, they can be planted or broadcast live. Note that when planting should not be too deep, the cotyledon exposed to the ground is appropriate. When the root water is poured, do not touch the water on the seedlings and soil so as not to affect the seedlings and survival.

Weeding and weeding combine weeding for cultivating, from shallow to deep. Note that when weeding, do not move seedlings and injure seedlings or roots.

After extending vines, 15 to 20 cm from the roots, fertilizing and composting manure, combined with photosynthetic nutrient fertilizer, can help plants absorb a lot of light energy, light, and provide plant growth and development.

When squash is crushed and squash is cultivated with pruning, sometimes the branches and leaves are too prosperous, and it is easy to cause squash. Therefore, it is generally applied to the vine shoots to promote the growth of the main shoot, promote flowering and fruiting, and promote the development of the squash. The side vines of the pumpkin should not be left too much. If there are special cultivation requirements, the vines should be pruned and stay on the side.

If the pollination is to cultivate squash or open cultivated pumpkins in the facility (flowering rainy days), in order to increase the rate and yield of pumpkins and prevent buds and stamens, it is possible to spray on them to promote the quality of pollen and increase the quality of pollen fertilization. Yield.
