Due to the large differences in climate between different regions, the colonization time of pumpkins is also inconsistent. As long as the pumpkin seedlings can be protected from freezing and normal growth, they can be planted or broadcast live. Note that it should not be too deep when planting, it is appropriate to expose the cotyledons to the ground. When pouring root water, do not touch water and soil on the seedling leaves, so as not to affect the slow seedling and survival.

Cultivating and weeding combined with weeding for cultivating, from shallow to deep. Note that when weeding, do not move the seedlings and hurt the seedlings or roots. In order to promote root development, when cultivating, it is necessary to cultivate the soil. During the whole period of pumpkin growing, it is generally necessary to carry out cultivating and weeding 2 to 3 times. Be careful not to spoil the pumpkin plants and leaves during cultivating.

After irrigating and topdressing the pumpkin, if the sensation is good, generally no need to fill the water. At this stage, we should carry out several times of cultivating, and at the same time, increase the ground temperature and promote the development of roots to benefit the cockroaches. After stretching the vines, 15 to 20 cm from the root, ditching and fertilizing, applying rotted manure, combined with spraying photosynthetic nutrient fertilizer, can help plants absorb a lot of light energy and light to supply plant growth and development.

When pruning and cultivating pumpkins, sometimes the leaves are too prosperous, and it is easy to cause the melons. Therefore, it is generally recommended that the flowering of the vines promotes the growth of the main shoots, more flowering, more fruit, and promote the development of pumpkin. The side vines of pumpkins should not be left too much. If there is special cultivation demand, pruning and vines should be carried out as needed.

If pollination is to cultivate pumpkin or open-decorated pumpkin in the facility (flowering in rainy days), in order to improve the rate and yield of pumpkin, prevent the dead buds and the dead fruit, spray the flower king 3 to improve the quality of pollen fertilization and increase the pumpkin. Yield.
