What is the reasonable method of applying base fertilizer to seedlings?

The role of seedling base fertilizer

Fertilizing seedlings can effectively promote the healthy growth of seedlings, prompt the early formation of seedlings, extend the life of old trees, delay the aging of old trees, improve the efficiency of photosynthesis of plants, and make the nitrogen content of each branch on the tree reach the highest level during the budding and flowering periods, and the lowest level at the end of vigorous growth.

How to apply base fertilizer for seedlings

The soil fertility of the nursery is relatively poor at the beginning. In order to improve the soil, it is necessary to apply base fertilizer, especially for sandy land. Generally, organic fertilizers such as manure, compost, oil cake or manure are used as base fertilizer and spread. Although the soil fertility needs to be very high, the organic fertilizer used when applying must be fermented first, otherwise fertilizer damage will occur.

How to apply fertilizer to seedlings

Topdressing is to supplement the deficiency of base fertilizer. There are three main methods of topdressing:

First, topdressing depends on the type of fertilizer. Different organic fertilizers have different effects. For example, nitrogen fertilizer has strong mobility in the soil and can be shallowly applied to the root distribution layer, while potassium fertilizer has poor mobility and must be manually applied deeply to the densely distributed root system.

The second is to fertilize according to the weather, that is, to determine the frequency and amount of fertilization according to different weather conditions, because when the temperature is low, the seedlings absorb less, and when the temperature is high, they absorb more fertilizer;

The third is to apply fertilizer according to the land. It should be noted that different soil types contain different amounts of required nutrients, so different types of fertilizers should be used when applying.
