Should I use urea or compound fertilizer for topdressing bitter gourd?

The compound fertilizer used for topdressing bitter gourd is complex in terms of nutritional structure. It can be regarded as a fertilizer made of nitrogen, phosphorus, potassium and trace element fertilizers in a certain proportion. In terms of fertilizer efficiency, since the nutritional structure of compound fertilizer is relatively balanced, it can meet the various needs of the plants and improve the nutrient deficiency of crops due to the lack of multiple nutrients.

Method of topdressing bitter melon

Dig trenches and apply fertilizer: dig a circular trench 20 cm away from the bitter gourd plant, with a depth of 5 cm, and then apply compound fertilizer. It should be noted that after each topdressing, watering is required so that the absorption effect is good. In addition, avoid applying fertilizer with water, otherwise the utilization rate of fertilizer will be very low and there will be serious waste.

Principles of topdressing for bitter melon

Bitter melon takes a long time to bear fruit. In addition to applying sufficient base fertilizer, topdressing should also be carried out. It should be done according to the principle of light application in the early stage, heavy application in the middle stage, and additional application in the late stage. Before flowering and fruiting, the plant growth is small, so thin fertilizer can be applied. In the peak fruiting period, the plant growth and fruit bearing proceed at the same time, and the demand for fertilizer is large, so heavy topdressing can be applied. In the late fruiting stage, the plant begins to age, so an appropriate amount of topdressing is sufficient.

Matters Needing Attention in Topdressing Bitter Melon

When applying fertilizer to bitter gourd, it is best to apply fertilizer in the morning and afternoon when the weather is good, not in the hot noon, otherwise fertilizer damage will occur. In addition, do not apply fertilizer too many times, and the concentration of fertilizer should not be too high. When applying base fertilizer, it must be fully decomposed, and water can be applied once after each fertilization.
