Lotus root fertilizing time
The fertilizing period of lotus root is mainly divided into three time periods. The first time is when the standing leaves just begin to appear, after cultivating and weeding, and the second time is after five days. It is carried out when six leaves are born, and the terminal leaf will appear on the third time, which is the lotus root stage, and the last fattening is carried out.
What kind of fertilizer should be applied to lotus roots?
1. Lotus roots absorb nitrogen quickly in the early stage of growth. Choose fertilizers with appropriate nitrogen content for fertilization. In the later stages, the nitrogen requirements of lotus roots gradually decrease. Lotus root is a type of crop that likes potassium, so the amount of potassium should be increased gradually in the later stages.
2. In addition to nitrogen and potassium, which need to be appropriately adjusted before and after fertilizing lotus roots, phosphorus is an indispensable element in the entire fertilization process. It is required during the entire planned period of fertilization. It should be added appropriately according to the living conditions and habits of the crops.
How to fertilize lotus roots
Fertilizing lotus roots should be determined according to the soil fat. If the soil is loose, fertile and rich in organic matter, 2500-3000 kg of livestock manure and 50-100 kg of quicklime should be applied per acre. kg, 25 kg of diammonium, 10-15 kg of potassium sulfate, 50 kg of superphosphate and 150 kg of cake fertilizer.
Precautions for fertilizing lotus roots
When fertilizing lotus roots, pay attention to the condition and age of the lotus root field. If the water level is low and the lotus root field has been continuously cropped for more than 5 years, the permeability of the lotus root field will change. The yield is extremely poor, and trace elements cannot meet the nutritional needs of lotus roots. Therefore, for this kind of field, it is necessary to conduct comprehensive deep plowing three years after planting, increase the proportion of organic fertilizer application, and control the amount of nitrogen fertilizer.
