The best place to fertilize fruit trees
Fruit trees mainly rely on root hairs in their roots to absorb nutrients. Therefore, the fertilizer application of fruit trees should be at the edge of the crown projection or slightly far away, not too close to the trunk, because there are thick roots near the trunk, fine roots and root hairs are less, which is not conducive to the absorption of fertilizer.
The principles of topdressing fertilizer for fruit trees should be as follows: the fruit trees with deep root distribution should be applied properly, and vice versa; organic fertilizer should be decomposed slowly, but the fertilizer supply period is longer, can be applied deeply, chemical fertilizer is mobile and can be applied shallowly. If organic fertilizer is applied to deep-rooted fruit trees such as pears, the depth should be 40cm to 60cm, while to shallow-rooted fruit trees such as plum trees, the depth should be 30cm to 40cm. After fertilization, it is best to spray new high-fat film to improve fertilizer efficiency.
For closed orchards or densely planted orchards, shallow application can be applied between rows and plants, and it is best not to hurt or hurt big roots. Only in this way can we give full play to fertilizer efficiency, improve fertilizer utilization rate, and achieve the purpose of increasing production and income.
