3. Fertilizer selection

How far it is from the roots when applying fertilizer depends on the size of the plant. If it is biennial, it should be 40 cm away from the root. If it is three years old, the distance should be 50 cm. If they are four years old or above, the distance should be 80-100 centimeters. The older the age, the further away the base is. Also, pay attention to the depth of fertilization. You should dig a trench 30-40 cm wide and 40 cm deep, and then put the fertilizer in, so that it can be better absorbed and work better.

1. The location of fertilization

How far away from the roots when applying fertilizer depends on the size of the plant. If it is a biennial plant, the distance should be 40 cm. Three-year-old plants should be kept 50 centimeters apart. Those who are four years old and above should be 80-100 centimeters away. That is, the older they are, the farther away they are. Because of their age, the longer the roots stretch, they should not be too close as it is easy to burn the roots.

2. Depth of Fertilization

In addition to paying attention to the location when fertilizing it, you also need to pay attention to the depth. Fertilizer must be applied within the distribution layer according to the distribution of the root system, so that it can be better absorbed and effective. When fertilizing, you can dig a trench 30-40 cm wide and 40 cm deep, which means the depth is about 40 cm. Too deep or too shallow will affect absorption.

3. Fertilizer selection

When fertilizing, the base fertilizer usually uses organic fertilizers such as pig manure, cow manure, duck manure, chicken manure, and manure. In addition, phosphate fertilizer has poor mobility, so it is mostly applied together with base fertilizer, using 25-50 kilograms of superphosphate per acre. If it is used continuously for many years, it can be stopped for one year. Later top dressing should use different fertilizers according to different growth periods. For example, during the germination stage, urea fertilizer can be applied. Phosphorus and potassium fertilizers should be applied before flowering to promote flowering. Top dressing is also required after flowering. Just use compound fertilizer to meet the needs.
