Matters needing attention for fertilization of pear trees in autumn

After the pear tree is harvested, apply enough base fertilizer in time, which is conducive to the production of high-quality pears in the coming year. The application of base fertilizer in autumn has a great effect on the growth and development of pear trees: the roots of pear trees enter the second growth peak from September to November, when fertilization is beneficial not only to the rapid decomposition of fertilizer, but also to the absorption and storage of nutrients by new roots.

Selection of high quality organic fertilizer

The base fertilizer is mainly organic fertilizer. Generally, each pear tree applies about 50 kilograms of rotten soil miscellaneous fertilizer or circle manure, 1 kilogram of superphosphate fertilizer, 0.2 kilograms of urea, or 0.5 kilograms of refined organic compound fertilizer Huimanfeng and Deledan. The amount of base fertilizer applied accounts for 60% and 70% of the fertilizer used in the whole year.

Flexible use of fertilization methods

The application method of base fertilizer can be flexibly mastered according to tree age and local customs. Pear trees with newly harvested fruit can be applied in ring ditches, open ditches according to the trend of root system, or open trenches between rows of pear trees, or dig holes. These methods should be carried out alternately from year to year. In order to reduce fertilizer waste, fertilizers should be applied deeply, with a depth of 30cm to 50cm. In case of drought, irrigate in time to adjust fertilizer with water. Sun Ting
