What fertilizer is best for lotus root

Lotus root fertilization time

The fertilization period of lotus root is mainly divided into three time periods. The first time is when the upright leaves just begin to appear, after inter-row cultivation and weeding. The second time is when five or six leaves are born. The third time is when the terminal leaves appear, which is the lotus root formation period, and the last fertilization is carried out.

What fertilizer to use for lotus root

1. Lotus root absorbs nitrogen faster in the early stage of growth, so choose fertilizer with appropriate nitrogen content for fertilization. In the later stage, the amount of nitrogen required by lotus root gradually decreases. Lotus root itself is a crop that likes potassium, so the amount of potassium should be increased gradually in the later stage.

2. In addition to nitrogen and potassium, which need to be appropriately adjusted before and after fertilization, phosphorus is an indispensable element in the entire fertilization process. It should be added appropriately according to the living conditions and living habits of the crops during the entire planned period of fertilization.

Lotus root fertilization method

The fertilizer for lotus root should be determined according to the soil fertility. If the soil is loose, fertile and rich in organic matter, 2500-3000 kg of animal manure, 50-100 kg of quicklime, 25 kg of diammonium phosphate, 10-15 kg of potassium sulfate, 50 kg of superphosphate and 150 kg of cake fertilizer should be applied per mu.

Lotus root fertilization precautions

When fertilizing lotus roots, pay attention to the condition of the lotus field and its service life. If the water level is low and the field has been cropped continuously for more than 5 years, the permeability of the lotus field will become extremely poor, and trace elements will not be able to meet the nutritional needs of lotus roots. Therefore, for such fields, deep plowing should be carried out after 3 years of planting, the proportion of organic fertilizer application should be increased, and the amount of nitrogen fertilizer should be controlled.
