Common application methods of fertilizer

Fertilization is a very important job when we are planting and producing. Appropriate fertilization is a key measure to ensure that crop growth and nutrition needs are met, so we must pay attention to fertilization no matter what crops are planted. There are many ways to fertilize, what are the specific ones? Today, Xiaobian has brought you common fertilizer application methods. Let's take a look at them together.

1. Circular fertilization

Circular fertilization is what we often call circular fertilization. Mainly in the crown around, a long distance from the place to dig a good ring ditch for fertilization. Although the operation of circular fertilization is relatively simple, and the fertilizer is economical, it is also necessary to pay attention to not cutting the horizontal roots, and the range of circular fertilization is relatively small, so it is only suitable for young trees. Then is the semi-circular fertilization, semi-circular fertilization is in the circular basis will be interrupted into about 3 pig trough fertilization ditch. This method has less root damage, can change the position of fertilization properly, and can expand the fertilization position, which is suitable for fire dragon orchards planted in hilly areas.

2. Radial fertilization

Radial fertilization is about one meter away from the trunk from the bottom of the tree, with the trunk as the center point, and then dig about 5 radial grooves outward. The depth of the ditch is usually maintained at about 30cm, and then fertilizer can be applied. Compared with circular fertilization, radial fertilization caused less damage to roots. However, we should also pay attention to avoiding big roots when digging trenches. Then every other year or so to pay attention to changing the location of the radiation ditch, improve the fertilizer surface, strengthen root absorption.

3. Irrigation fertilization

Irrigation fertilization is to combine topdressing with watering. Over the years, China's drip irrigation technology has gradually matured, and this fertilization method has been slowly applied. Irrigated fertilization, whether sprinkler or drip. All of them can supply fertilizer for crops in time, and the fertilizer can also be evenly distributed, which will not affect the roots, but also protect the soil structure of the cultivated layer, and its fertilizer utilization rate is also very high. Therefore, in recent years, this method of irrigated fertilization has gradually become hot and has been used in many places.

4. Fertilization of the whole garden

For some mature trees or closely planted orchards, whole-orchard fertilization is the main method of fertilization. Because at this time, the roots have basically been distributed to the whole garden, so the whole garden should be sprayed in place. Sprinkle the fertilizer evenly into the garden first, then put it into the soil about 20cm. The roots can absorb fertilizer evenly and well, but because the fertilization depth is shallow, the roots are easy to turn up, and their resistance is reduced. It can be applied alternately with radial ditch fertilization, which can complement each other to improve the maximum use of fertilizer efficiency. Finally, there are foliar fertilizer fertilization methods, foliar fertilizer absorption is fast and effective, can meet the urgent need for nutrition of fruit trees.

The above is a brief introduction to the common application methods of fertilizer. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
