Depth and time of fertilization for pear trees

In China, the planting area and yield of pears are second only to apples, and one of the important factors affecting pear yield is the depth, time and method of fertilization, which will be introduced below.

1. Depth and time of fertilization for pear trees

Sprouting fertilizer was applied before pear sprouting, boric acid solution was applied at flowering stage, potassium fertilizer was applied mainly in May and July, long fruit fertilizer was applied from June to July, strong fruit fertilizer was applied from August to September, and base fertilizer was applied after fruit harvest. In addition, when applying organic fertilizer, phosphorus and potassium fertilizer, the depth should be kept at 20-60cm, and the principles of deep application of base fertilizer, shallow application of topdressing, deep application of deep root and shallow application of shallow root should be adhered to.

II. Fertilization methods for pear trees

1. Annular furrow fertilization

In the outer part of the crown, a circular ditch is dug for fertilization, and the ditch depth is determined by the root distribution depth. The method is relatively simple and suitable for the fertilization of young trees.

two。 Radiation furrow fertilization

Take the tree body as the center, dig 4 or 6 radial trenches around the crown at an equal distance. The ditch is 30 cm wide and 20-30 cm deep, and requires shallow inside and deep outside. The length of the ditch depends on the size of the tree.

3. Furrow fertilization

This method is a kind of fertilization method which is widely used in pear production, and can be operated mechanically, specifically by opening ditches between rows of pear orchards. The ditch is 50 cm deep and 50 cm wide. Fill it with soil after applying fertilizer. This method can be replaced with radiation ditch fertilization every other year.

The fertilization methods of pear trees include burrowing fertilization, irrigation fertilization and other methods, which can be determined by the majority of growers according to the situation in the field, and can be adjusted appropriately if they do not want to apply.
