When many fruit farmers fertilize fruit trees, the fertilization site is too close to the trunk. This not only reduces the utilization rate of fertilizer, but also damages the roots of fruit trees, affecting the rooting, flowering and fruiting of fruit trees, resulting in reduced yield.
The absorption of fertilizer by fruit trees is mainly done by the root hairs in the roots. Fertilization in the root hair area can improve the utilization rate of fertilizers, increase production and increase income. The roots of apple, peach, plum and other fruit trees are distributed shallowly, about 40 cm. The roots of pears, grapes and other fruit trees are distributed deep, about 80 cm. Fertilization should be applied at the edge of the crown projection
Or a little further, the fruit trees with deep root distribution should be applied in a deep manner, and the shallow application should be applied. It should also be noted that the organic fertilizer is slow to decompose and the fertilizer supply period is long. It can be applied in a deep manner. For densely planted orchards, it can be applied deep in the line and applied shallowly between the plants. It is best not to hurt or damage the roots. (Han Lu)
