In the management of the orchard, some fruit farmers apply fertilizer close to the trunk, which not only damages the root system, but also reduces the fertilizer efficiency. The correct fertilization position should be at the outer edge of the canopy or a little further away.
The absorption of fertilizer by fruit trees is mainly done by the root hairs in the roots. If the fertilizer is applied to the concentrated distribution of root hairs, the fertilizer utilization rate will be increased. The horizontal root distribution of fruit trees is about 1 to 1.5 times the crown diameter of the canopy; the vertical distribution of roots varies with tree species, soil quality and management level. The roots of apples, pears, citrus and grapes are distributed deeper, up to 80 cm. However, most of the absorption roots are concentrated in the depth of the soil layer of 40 to 60 cm. The roots of peach and plum are distributed shallowly, and most of them absorb the roots in a soil layer of about 40 cm. Therefore, when fertilizing fruit trees, it is necessary to carry out the above-mentioned characteristics. When organic fertilizer is applied, the decomposition of organic fertilizer is slow, and the fertilizer supply period is long, and it is suitable for deep application; the fertilizer has greater mobility and can be applied shallowly. For densely planted orchards or closed orchards, it is advisable to apply them deep, but be careful not to hurt or damage the roots. Combined with the application of photosynthetic nutrient film fertilizer (light fertilizer) and plant electronic fertilizer.
