The yield of lotus root will be higher if you use organic fertilizer, urea, and phosphate fertilizer. When using urea, you must pay attention to the growth and development time of lotus root. Under normal circumstances, top dressing should be carried out according to the time of leaf establishment. The details are as follows:

Organic fertilizer:

Organic fertilizer is better as a base fertilizer. Remember to apply enough base fertilizer.

Urea:

Choose urea for top dressing in the seedling stage. During the growth and development process of lotus root, top dressing is usually carried out 2 to 3 times: the first time when standing leaves begin to appear, and the second time when top dressing begins. It is carried out when there are 5 to 6 standing leaves. The third top dressing is carried out when the terminal leaves appear. At this time, lotus roots begin to form. Top dressing can promote the expansion and growth of lotus roots.

Phosphate fertilizer:

Spray potassium dihydrogen phosphate foliar fertilizer 2-3 times when lotus roots are forming, and spray once every 7-10 days. This effect is also very good. of.

It should be noted that fertilization should be carried out in sunny and windless weather, and avoid doing it at noon in the scorching sun. In deep-water lotus root fields, fertilizers are easier to lose, so liquefied fertilizers cannot be applied directly. Solid fertilizers can be used; and then topdressing is carried out. When using chemical fertilizers, first mix the chemical fertilizers with river mud thoroughly to make a fertilizer mud ball, and then apply it to the lotus root field, so that the effect of top dressing will be better.
