How to apply fertilizer to plant lotus root

Planting lotus root requires fertile soil, which shows that lotus root growth needs to consume a lot of nutrients, so when planting, it is necessary to pay attention to how to fertilize and how to top fertilizer. What is the fertilizer principle of lotus root, and how to apply fertilizer according to the growth stage. What kind of fertilizer is suitable for use at each stage. Please continue to read our next introduction.

1. The principle of fertilizer requirement

Lotus root needs a lot of fertilizer, lack of fertilizer, the plant is very small, the leaf is small, the lotus root is also small. It is necessary to apply fertilizer early and should not be excessive. The nutrient consumption in the water is relatively fast, and the best way is to fertilize the pond in an all-round way. Farmed fish and shrimp can improve the microenvironment, and excreta can be used as fertilizer. Organic fertilizer is more suitable, because it needs a large amount of fertilizer, which is helpful to the fertilizer pond and has good quality. Proper supplement of calcium phosphate, phosphorus is very important for growth.

2. Use of base fertilizer

For the fields that are going to grow lotus root for the first time, apply base fertilizer two weeks before planting, turn the soil 30 centimeters deep, apply base fertilizer a few days before planting, use about 6,000 jin of human and animal fertilizer per mu, and use completely mature farm manure. In addition, add some chemical compound fertilizer, about 100 jin. If it is a field that has been planted with lotus root, it is OK to apply 3000 jin per mu. Compound fertilizer is about 60 jin. Deep ploughing and fertilization, planting in shallow water.

3. Fertilization stage

When you start to grow leaves, fertilize once and apply two thousand jin of manure per mu. If the fermentation is prepared in advance, it can be used. The second topdressing is when the plant has six leaves, the same amount as the first time. The third time is to topdressing before flowering, this time the use of topdressing has increased, about more than 2,000 jin. Generally speaking, the application of base fertilizer of lotus root is less, which mainly depends on topdressing in the later stage.

4. Points for attention

There is no fertilization at noon when the sun is strong. It is best to apply fertilizer in the morning and afternoon. Fertilizing at a low temperature is better, because although the fertilizer has been fermented, the concentration of the fertilizer is too high, which suddenly affects the growth. Put some water before fertilization, the water in the pond is generally deep, fertilizer can not go into the soil, and then dissolved in the water, the root absorption is not very easy. Solid fertilizer absorbs better than liquid fertilizer. Topdressing can be mixed with mud for absorption.

The cultivation of lotus root needs a lot of fertilizer, so it is necessary to apply sufficient base fertilizer and apply fertilizer in time at each stage. To ensure good growth.
