Fruit trees are fertilized too close to the trunk
When many fruit growers fertilize fruit trees, the fertilization sites are too close to the trunk. This not only reduces the utilization of fertilizers, but also easily injure the roots of the fruit trees and affects the rooting, flowering and fruiting of the fruit trees, resulting in reduced yields.
The absorption of fertilizers by fruit trees is mainly accomplished by root hairs in roots. Fertilizing in root hairs can increase the utilization of fertilizers and increase production and income. Apples, peaches, plums and other fruit trees have a shallow root distribution of about 40 cm, and pears, grapes, and other fruit trees have a deep root distribution of about 80 cm. Fertilization should be applied at the edge of the canopy projection or at a little distance. The deep-rooted fruit trees should be deep-applied and shallow. It is also important to note that organic fertilizers are slow to decompose and have a long fertilizer supply period. They can be applied in depth. For densely planted orchards, they can be applied deep in the rows and shallowly applied between the plants. It is best not to hurt or damage the roots.
